NASA: #HurricaneMichael intensifying – now 150 MPH winds at landfall, nearly Cat5

UPDATES BELOW

The latest GOES16 satellite closeup of the eye of Hurricane Michael at landfall.

Live Source here

This morning, it has further intensified and now stands on the threshold of a CAT5 storm. It would become Cat5 at 156mph sustained winds.

NASA: Max sustained winds in high-end Cat 4 have unfortunately continued to intensify, now at 150 MPH! Pressure down to 27.26″. ( GOES-East 30-sec vis imagery)

If it is not a poor coordinates tracking, I would guess it might be to do with the rate of updating (looking at its today’s back data), i.e. wind graphic appears to be updated every hour, while graphic for the storm centre marker might be updated more frequently.

So they model the wind speed from the temperature of the eye compared with the cold cloud tops?!? We know how that goes — while I’m not belittling the hurricane, I predict on-the-ground wind speed measurements will be significantly less than these model-driven predictions.

From https://hypertextbook.com/facts/2007/DmitriyGekhman.shtml quoting Beiser, Arthur. Schaum’s Outline of Applied Physics. McGraw-Hill, 2004.:

“At 100 °C and atmospheric pressure … the density of water is 1000 kg/m3, and the density of steam is 0.6 kg/m3.”

The intense rainfall is condensing water vapor. When water vapor condenses it occupies a lot less space than in the vapor phase, thus creating a vacuum. Although water vapor is not condensing at 100 °C, the relative densities shown above can give you an idea of the vacuum engine that is driving the hurricane. When starved of moisture, the hurricane dissipates.

It’s normal to have big storms.

It’s been that way for centuries, with often 5 or even 7 major hurricanes hitting the US in one year (search Steven Goddard / Tony Heller for tons of posts on this, or input simply site:realclimatescience.com hurricanes or variations of that).

It’s NORMAL to have big storms. But with every single storm the leftists start screaming “climate change! climate change! climate change!” No, it’s normal to have devastating storms. They are proof of nothing abnormal.

Joe Bastardi who works in the real world would dispute that statement–see him at WeatherBell Analytics.
Has anyone seen the Allstate Insurance Commercials where the actor who portrayed the POTUS on TV Drama series 24 make a statement that (26) 500 YEAR EVENTS have occurred in the last TEN (10) YEARS? With the ten year drought in mind how is it he can justify that statement?

October 10, 2018 9:12 am

Models had the path correct from the start…failed miserably with the intensity. Think it was slower thsn projected, which allowed more time for intensification, but still…it was supposed to be a TS or Cat 1, then Cat 2, then Cat 3…now Cat 4 and possible 5, basically with those upgrades daily.

Odd that the hurricane center reports sustained winds of 155 MPH and gusts of 175 MPH, yet Tyndall AFB reports maximum gusts of only 128 MPH and the eye has already passed directly overhead. Either the max wind field is very, very small or some serious over-estimations are going on.

The ground based recordings and observed damage to trees and buildings will likely reflect cat 2 to cat 3 at most. We will see if storm surge hit the 14′ predicted anywhere. It is not accurate to compare today’s storms with past storms before satellite surveillance and numerous air reconnaissance.

Reply to  David A
October 10, 2018 12:10 pm

Yes, the jet stream above is traveling at about 200 MPH, which by the same general criteria means that I must be in a Cat 5+ storm …

It’s similar to picking arbitrary starting points to establish a trend. We are already seeing the downside where more and more people are ignoring warnings knowing that they consistently over-estimate the land strength of storms. The resulting apathy is going to kill people when a legitimate cat5 storm is on the way. Is this what the alarmists are trying to achieve in order to justify their position?

David A
Reply to  co2isnotevil
October 10, 2018 12:07 pm

Not surprising. Expect ground speeds sustained of cat 1 or two and ground damage to reflect that. Comparing past hurricanes to today’s satellite tracked and frequent storm flight monitoring is simply not accurate. Going off of storm surge and land based damage is more accurate. This is a dangerous cat 2 or 3 hurricane based on earlier storms.

It’s more likely that the power failed and there was insufficient battery backup and/or there was no network connection. If it’s broken, it’s inoperative, but if it’s inoperative, it’s not necessarily broken.

I will eat my hat if sustained wind speeds on land exceed 110mph anywhere in the path of the storm.
Wind speed at 1000 ft. just scares people unnecessarily. And when a big storm really arrives, they will think they “already lived through a Cat 4 storm, and it was no big deal”, and they will be in real danger.

Not that 110mph isn’t bad, but it isn’t as devastating. Now the flooding, that will be a real problem.

Back in the mid ’90s while sailing in the NW Caribbean we ran into a real character, A retired weather service guy, who’s job was to fly on hurricane hunters and estimate the wind speed by judging the sea state (i.e., the height of the waves and amount of spindrift). We suggested that flying through a hurricane at that low of an altitude must have been fun. He just smiled an poured himself another drink.

Remembering correctly the instrumentation blew off the NWS station in Miami at 140 mph during Andrew. I remember another set of instrumentation blowing off another NWS facility at 140 also. Coincidence just kind of stuck in my head. Kind of became my benchmark for CAT 4-5 storms. Maybe the instrumentation is more robust these days.

Click on the icons on the left side of the data list for graphical output. Pressure dropped like a rock to a low of 28.87 so likely eye passed over it or very close. Max sustained wind ESE at 54.4 knots (@ 5 meters). Peak gust was 66 knots.

There is the SFMR instrument on both NOAA and USAF aircraft. The last pass by the Air Force showed a SFMR surface wind of about 135 kt (155 mph). But we will have to wait for anemometer readings from Tyndal AFB and Panama City. Problem is, at these wind speeds, you often have instrument failures.
Also the Texas Tech team has set up a stick-net of portable wind instruments. But it takes a while for them to make data available.

Reply to  Greg S.
October 10, 2018 1:04 pm

Just checked out Texas Tech’s Facebook page, and it seems they didn’t deploy for Hurricane Michael. Ouch! Here is their reason:

For those wondering, we will not be deploying for #Michael. A few days ago the intensity forecast had too many caveats and questions as to if it would meet our NE Gulf Coast deployment criteria. Once this became more clear yesterday, we felt with the forward speed of Michael we could not deploy safely under a compressed timeline. For us, safety always trumps science. Unfortunately these are the factors we must consider given the significant driving time between Lubbock and the Gulf Coast. Other factors also include personnel time and funding support for the program. Good luck, collect great data, and stay safe to the other research teams deploying!

It’s annoying the time lag for NWS web data. Viz: it is 1800Z now and the latest I can find for Tyndall AFB https://w1.weather.gov/data/obhistory/KPAM.html is

10 10:56 E 41 G 66 1.13 Heavy Rain Fog/Mist and Windy NA 77 77 100% NA 78 28.97 981.3

So, they had a gale force 8 there but I believe the 10:56 is CDT or 15:56Z, i.e 2 hours ago. This should be one of, if not the, windiest places in the NWS stations, so I’ll keep an eye on it.

Be great if we actually saw sustained hurricane speed there, but I’m not betting on it.

October 10, 2018 11:24 am

I’ve searched many of the weather stations reporting on my Wunderground weather app, and I cannot find one station reporting sustained hurricane force winds, not even gusts above 74 mph. Most stations’ sustained winds are well under 50 mph. I looked near and far to the eyewall, east, NE, north, NW and west as it came ashore directly over Tyndall AFB. After eye passage, Tyndall is reporting 45 mph sustained wind. How can that many stations be that wrong?

Also, the few live webcams in Panama City Beach that are operating show moderate waves, beaches are visible, and there is little damage to beachfront wooden structures.

It seems that satellite and aircraft-borne storm estimates greatly exaggerate the real situation on the ground.

pflashgordon: Actually Apalachicola, a bit further east, has had hurricane force gusts and a sustained wind close to Storm Force 11, despite its pressure 986mb being higher that Tyndall’s 981mb:

10 12:53 S 58 G 84 0.25 Heavy Rain and Windy BKN009 OVC015 81 NA NA NA 79 29.12 985.9 0.48

It’s worth keeping an eye [sic] on both of these, but they only seem to update hourly. Or do they just turn them off around hurricane time so the public who pay for them can’t get to see what’s actually happening?

Apalachacola pressure minimum was 29.1″Hg at 1:30, Peak sustained winds at 1:18pm of 62mph, with gusts to 72mph. This is Tropical Storm category windspeeds.

Perhaps the “models” need a little refining, or much more. Either that or the past few years hurricanes die down at the very sight of land or buoys. Solve the catastrophic damage of hurricane winds by installing buoys lining the shores and create a new Category scale to Category 8 or even 19! It will be unprecedented to have Category 19 hurricanes caused by Global Warming and of course CARBON! Even the heat is hiding in the deep ocean where there are no instruments.

Yes, 1:17pm of my comment refers to PDT I think, so it must be 3:17pm or 4:17pm now in Panama City. Perhaps the equipment has broken and we won’t see their maximum wind speeds. John Pickens whaddya think?

Looks like the data feed crapped out at 12:15pm local time. Sustained winds of 64mph at that time. I very much doubt it ever reached 110mph sustained, but we may never know from this weather station.

The damage to Tyndall AFB will be enormous, very much like Homestead AFB, FL in 1992 after Andrew.
Hurricane Andrew wiped Homestead Florida off the map in late August 1992.

Any guesses on when the period of Rapid Intensification for Andrew occurred from this historical plot of Ap Index?
comment image

Geomagnetic Ap index spiked this past Monday Tuesday, not quite as high as forecast, but still spiked. That coincides with Hurricane Michael’s rapid intensification over these past 48 hours.

One can go back to 2017 and see the same sort of intensification for Hurricanes Irma and Maria coinciding with the whopper Ap spike as Maria was bearing down on Guadeloupe in the Lesser Antilles. Irma stayed an amazing Cat 5 for 5 days from Sept 5 to Sept 9 as Ap index hit it highest level of Solar Cycle 24.

Certainly an Ap spikes by themselves are not sufficient to bring on a major hurricane development as there are exceptions where Ap spikes don’t correlate with hurricane development. For example the 2015 hurricane season was a minimal Atlantic hurricane year, likely due to the very strong El Nino in the eastern equatorial Pacific through the hurricane season keeping the wind shear high over the tropical Atlantic.

So other factors must also be in place, such as water temps, broad pressure patterns, and maybe a neutral/near-neutral ENSO. But there does appear to be a role for Ap spikes assisting in shifting the atmospherics toward one favorable for hurricane development and intensification.

Joel, you should do some statistics on that Ap index stuff, and prove a correlation. Otherwise it’s just anecdotal I fear.

Re the damage to Tyndall AFB, let’s see. Above I wrote “Tyndall peaked at 75kt sustained and 112kt gust”. So the sustained wind was probably OKish, but that is a big gust differential, and that 130mph really may have done some damage. Hope everyone was hunkered down, or absent.

The big damage to Tyndall AFB will be the storm surge flooding in the housing and base facilities with salt water.
Tyndall AFB has a listed airfield elevation of 7 feet. That would be the ends of the main runway. Most of the main part of the air base is between 4 to 12 feet.

“At 2:12 pm EDT, the storm tide at Apalachicola, FL peaked at 7.72’ above high tide (Mean Higher High Water, or MHHW), which was the highest water level on record there (going back to 1967). Hurricane Dennis of 2005 (a 6.43’ storm tide) held the previous record. The highest storm surge at the site (height of the water above the normal tide) was 8.53′. NHC predicted a storm surge of 8 – 14 feet for this portion of the coast.

At 2:06 pm EDT, the storm tide at Panama City, FL peaked at 5.31’ above MHHW, which was the second highest water level on record. The record was 5.72’ above MHHW, set on October 4, 1995 during Hurricane Opal. The highest storm surge at the site (height of the water above the normal tide) was 5.62′. Records extend back to 1973 at the site.”

So, interpolating between 5.3 feet above MHHW at Panama City and 7.7 feet above MHHW at Apalachicola, puts Tyndall AFB at 6.5 feet above MHHW from Michael’s storm surge.

The next named TC for 2018, Tropical Storm Nadine has just formed out in the eastern Atlantic development region. Currently Nadine’s max winds 63 MPH and 993 mb central pressure estimate at 12.6 N 31.6 W headed west-northwest, at least a 7-10 days out from any significant landfall.
And the next Ap spike is forecast for around 19 October. So “If” Nadine is still over favorable waters for strengthening, expect it to do so then. And in 9 days that could put it bearing down on Florida or into the Gulf of Mexico where the waters are still quite warm. Or she could just get steered off into the North Atlantic near Bermuda. Too early to tell her track.

It is now 5:09pm EST, and the NWS/NHC website lists “Hurricane” Michael as a “Major” hurricane with maximum sustained winds of 125mph. Yet, there are no ground stations reporting sustained winds of greater than 74mph. This storm landed as a Tropical Storm. Why is this happening?

Does anyone know of an actual report of a weather station in the effected area which reported anything near hurricane force sustained winds? I’ve been scanning websites, and I cannot find one.

This is a farce.

Yeah, well there they are using the word “wind” for gusts rather than sustained winds, which is a bit of a cheat, making people think they’ve been in a hurricane rather than a tropical storm. And they immediately throw in km/h to make it sound more scary.

Well, John, we saw upthread that Panama City stopped recording around 12:15pm when the sustained wind was close on 74mph, still apparently increasing, and with the barometer still diving. So I think we can be pretty sure the winds continued to increase. But up to what Category? It certainly would be nice to have solid data, I agree, but unlike some other hurricanes I have commented about, especially Sandy, I am reasonably persuaded that this was a landfalling hurricane.

Shell structures for storage (like boats) don’t withstand much wind (and the boats look like they are still safely inside). The residential condo in the background looks unscathed.
I feel for those with damage, I’m sure a lot of roofs were damaged, but I drove the coast after both Camille and Katrina, and so far I haven’t seen anything approaching the devestation caused by those storms. I hope that continues to be the case.

This was a 155 mph sustained wind storm as conveyed by the NHC. The AFB noted is right at the point of impact for this storm, and right on the water. What I am I missing with intensity?

Pensacola dodged a bullet.

“Blessed are those that experience a NH Hurricane on the west side of the storm. And, woe to those to the east.”

Much will be made of Michael, deservedly so as the people in the affected areas will suffer from lack of power and all the comforts that electricity brings, possibly loss of water and sewage disposal, perhaps little food if not prepared, lack of communication services, maybe little access to medical help, exposure to the elements, flooding, the stress of losing much, if not all, of the things people treasure, maybe trauma from the loss of friends and relatives……get the picture? Its not the technical aspects that are important, its the damage that is caused. Fortunately, if that is the proper word, Michael affected a less populated area of our state but that’s little comfort to those that reside there.

Pensacola is similar to the Panama City area. Smaller, large military presence, coastal and, thus, exposed but we had not had a direct hit from a hurricane hit for decades until 1995 when Erin visited followed by a near miss from Opal. Mobile, AL was hit by Frederick in 1979 and Pensacola experienced some effects but the last hits were from the “Decade Storms in 1906, 1916 and 1926. What an eye-opener for the area as the collective historical memory had receded. Then, we went through the “eye” of Erin and Opal veered to the east at the last minute it seemed. Pensacola was hit again in 2004 from Ivan (we were in, or near, the east eyewall, an exciting experience) and again in 2005 from Dennis (we were in, or near, the west eyewall) and had a glancing blow from Katrina in 2006. Instantly in 1995 and then for a span of about 10 years the collective memory was re-awakened and reinforced several times! Our neighbors to the east will be experiencing that feeling now.

We have a large oak in the backyard, a LARGE oak. Ivan leaned it one way, Dennis back the opposite way, and Katrina straightened back up to the vertical. A natural weathervane. Funny how the mind works. I rate hurricane intensity at my house by how many days the power is out: Erin for 3.5 days (Cat 1 but a direct hit), Opal for 3.5 days (Cat 3 at landfall but read more below; stronger but not as close), Ivan for 9 days (Cat 3 and direct hit), Dennis for 3 days (Cat 3 but west side), Katrina for 1.5 days (Cat 3-5, Cat 3 at landfall but farther away from Pensacola), Michael for 0 days. However, in each of those cases there are people who were affected much more. lost much more including their lives. Its not the wind, pressure, etc. ratings; its the impact.

Opal was an interesting storm and I told my younger son, who lives to the east of Destin, to keep a close eye (no pun) on Michael as it reminded of Opal. As Opal was headed north, straight for Pensacola in 1995, it was designated a hurricane on October 2 and strengthened to a Cat 4 by October 4 fueled by unusually warm water thought to be associated with the Loop Current. As Michael was traversing nearly the same waters I told my son to watch for rapid strengthening which turned out to be the case.

Michael is not the first storm of this strength to hit the northern Gulf Coast. Camille (1969) was stronger, Katrina was devastating (a Cat 5 at one point) and Opal achieved a 155 mph winds before weakening to a Cat prior to landfall. But it is the strongest to hit the Florida panhandle, and as I said, any hurricane is a bad day if it comes to your house.

We prepared well prior to each of our hurricane visitors and got better at it each year. After Katrina in 2006 we installed a whole-house generator and hardened the house through FEMA’s Wind Mitigation Program which I highly recommend for anyone in hurricane country (and tornado country). We are only a few miles from the coast but at 80 feet MSL so storm surge and flooding are not an issue for us and surge/flooding are the major killers during these storms.

It took several years to recover from Ivan. Major bridges in the area were unusable. Beach areas were rearranged and had no services for months, tens of thousands of structure were destroyed and tree canopies were reduced by about 80%. Housing was in very short supply and home prices skyrocketed. A benefit: no insects! It took me eleven days to clear debris from the property but not a flying insect in sight. They were all blown north with the storm! But, they were back about 14 days later.

So, as the debate will rage about strength of a storm, remember the impact on people’s lives. As coastal development and population increases, the impacts will be greater, recovery costs greater (particularly with inflation) but, hopefully, development will be smarter. Our Panhandle, Big Bend and west Coast Florida neighbors will recover. Some faster than others. Some with life-changing memories. All with a new perspective on what is important. I’ve been through a number of hurricanes, even more tropical storms, and they are a marvelous and frightening display of power and deserve much respect. I know that many of you have as well or have experienced a tornado (I remember going through Grand Island, NE decades ago after the town was essentially wiped from the face of the planet), or earthquake (been there, too), or an explosion, fire or war. Leaves a mark.

Oh, a final comment, as for hurricanes: its weather, just weather.

Sorry for the wordy post.

Erin took out all the sand pines in my back yard with its slow approach and heavy rains. The trees just laid over, their root balls lifting out of the sand. Power out for 4 days. Then 2 months later Opal went right over my house in Navarre took off half the roof, dropped much of the sheet rock ceiling inside with insulation everywhere. Power out for 4-5 days. I love the beach and water, but I left Florida forever 6 months later (for permanent living) in June 1996.

On October 4, 1995 at 1200 GMT Opal hit a minimum central pressure of 919 mb. It was very briefly a Cat 4, but really just a solid Cat 3 at 12 hours before landfall. Then it hit some colder water as it moved north toward the panhandle and made landfall right over my house as a minimal Cat2. (Iwas stuck in 40 mile long I-10 parking lot about 20 miles outside Tallahassee. I spent the night in my 4Runner with my wife and 3 small dogs along with 50,000 neighbors.

Keep in mind that the NHC uses a 1-minute time average for their sustained winds. Observation stations use a 2-minute time average for computation of sustained wind. That can result in a significant difference between what NHC reports vs. what observation stations report.

This is not a “natural disaster” according to CNN and according to them, it is “dangerous” to talk about it in such a way. Much more dangerous to call it a natural disaster than the hurricane itself.

“”Hurricane Michael isn’t a truly “natural disaster.”

Neither was Harvey in Houston.
Nor Maria in Puerto Rico.
Yet we continue to use that term.
Doing so — especially in the era of climate change — is misleading if not dangerous, according to several disaster experts and climate scientists I reached by phone and on Twitter.”
