Hurricane expert Klotzbach: #Irma at landfall comes in 7th behind 1935 Labor Day storm

While this won’t be of much comfort for those that are squarely in it’s path right now, it is a small bit of good news. Dr. Philip Klotzbach has compiled rankings of both hurricane Irma and Harvey when they made landfall. Compared to the 1935 Labor Day storm, Irma is a distant 7th, tied with the 1928 Lake Okeechobee storm.

He writes:

Table of all hurricanes with landfall pressures <= 940 mb at time of U.S. landfall. was 929 mb and was 938 mb.

With Irma ranked 7th, and Harvey ranked 18th, it’s going to be tough for climate alarmists to try connecting these two storms to being driven by CO2/global warming. But they’ll do it anyway.

I turn off the audio when viewing the Weather Channel, to avoid the possibility that I will lose control and put something handy thru the TV screen. Right now they are claiming that Tampa has not seen a major hurricane since 1921. From the looks of the Hurricane Center estimates, they still won’t have seen one when Irma passes by. They estimate Irma as leaving major hurricane status less than halfway up Florida – quite a distance from Tampa.

To be fair, the claim was a direct hit. Eyewall. We know what that means because we too a direct hit from Wilma in 2005. Being just 15 miles away can make a huge difference. Andrew made a direct hit on Homestead, yet south Miami just 27 miles away had almost no damage because Andrew was spun up so tight and small.

Do far it is clear, Irma and Harvey; the two weakest ground based CAT 4 landfall storms in history!
Zero people should say I am minimizing the pain inflicted on people from this storm. I am not. I just want the facts on ground based wind readings to compare to past storms.

As this thread is newer, I am just posting three of my recent comments from the older “maue expert” thread:

If people want to keep an eye on winds speeds recorded by buoys, use the link http://www.ndbc.noaa.gov/radial_search.php?lat1=25.0n&lon1=80.0w&uom=E&dist=150&ot=A&time=8 .
Fowey Rock, FWYF1, see http://www.ndbc.noaa.gov/station_page.php?station=FWYF1 , has been recording the highest speeds for the last few hours, between 60 and 70 knots, i.e. Category 1 Saffir-Simpson. Interestingly Fowey Rock is on the Miami side. Hurricanes going north typically have the highest winds on the east side, so perhaps, emphasize perhaps, Naples isn’t in too much danger as the eye approaches it. There could be higher winds on land of course just to the east of the eye.
Does anyone have a link to the nearest NWS station to Naples?
Rich.
Sorry, I just saw bw’s posting https://wattsupwiththat.com/2017/09/09/hurricane-expert-maue-irma-may-bomb-to-cat-5-again/comment-page-1/#comment-2606353 . There he also talks about Fowey Rock, and the fact that the anemometer height is 44m, well above the official 10m level.
Rich.
Homestead Air Base station KHST, south of Miami and not too far from the sea, stopped reporting winds after 11am having had a gust of 62mph out of a sustained wind of 28mph.
Enquiring minds want to know: did a gust take it out or is the NWS trying to starve its customers, you the people, of accurate information?
Rich.

And their estimate for 10m height is 52kts, which is below hurricane strength.

The badness of hurricanes besides how fast the winds and how low the pressure should also include where they strike and how long they linger. This one’s going skate up the Florida coast and do a lot of damage as opposed to going straight inland and decaying to a lesser status.

September 10, 2017 9:47 am

Following my gripe about non-functioning NWS sites, I shall now gripe about non-functioning webcams in the Naples FL area. I’ve tried several, and none are working. Do webcam owners turn them off when a storm is approaching, just in case they get damaged? It would be quite interesting to see a car (say) being blown into a webcam in its last moments on earth…
And I expect the insurance would pay.
Naples does seem to be in the current path of the eye, so observations there could be crucial in understanding the nature of this hurricane.

You don’t “rank” it Griff because we have no reliable long term data for wind speeds of offshore hurricanes, so what would we “rank” it against? The frantic effort you refer to is merely trying to keep some kind of sense of proportion in the dessemination of “information” in times of crisis and natural disaster. We don’t need hype and horse puckey, particularly from government funded agencies who are supposed to simply record and report what they measure. As the MSM beclowns itself more and more, rational people just tune them out.

Griff,
It still ranks lowly.
Outside the US it has to compete with the most extreme storms, like Labor Day, Camille, Allen, Gilbert. Rita and Wilma, all 900 hPa or lower. Plus all those between 900 and Irma’s pressure.
You could easily have looked up these facts yourself.
BTW, did you notice that yesterday 2017 Arctic sea ice extent surpassed 2008, making this year the seventh lowest since 1979, after 2012, 2007, 2016, 2015, 2011 and now 2008? Good chance of beating 2010, too.
Don’t you feel foolish for making such the ridiculous prediction that this year was “sure” to be the lowest Evah! The low record of 2012 is liable to stand for years, if not decades, at least.

Griff,
Alarmists were right about nothing.
Irma wasn’t any stronger at any point in its path than many other hurricanes from long, long ago.
Nothing is happening in earth’s climate or WX that hasn’t happened over and over again before.
The null hypothesis can’t be rejected. Indeed, it’s the only hypothesis for which there is evidence.

If you look at Irma’s rank as its maximum, it would tie with Wilma in 2005. And in 2005 we would have four cat 4 hurricanes if you look at maximum (Dennis, Katrina, Rita, and Wilma) as compared to two for 2017 (Harvey and Irma). So yes, the 12 year streak is broken, but we’re nowhere near as bad as we were just prior to the streak.

Historically, the strength of a hurricane is unknown prior to hitting land.

Assume hurricanes are getting stronger and more frequent. We have taken steps to compensate for that though Houston suggests there is more to do. Our ‘eyes’ are better (using satellites). Our predictions are better. Our knowledge is better. Our communication methods of the dangers are better. As Luddites we could have never have developed fast enough computers for hurricane predictions and everything that goes into our weather satellites and it might be suggested we’d be at greater risk from hurricanes.

IMO there was enough info to have ordered evacuations from Houston, but the mayor didn’t. Shades of Katrina, when the mayor of NO and governor of LA refused to order evacuation or seek federal aid in time.
The problem in Houston is development and subsidence. The WX pattern which kept the storm over the same area, not much people can do about that.

Smarter development could somewhat lessen the impacts of heavy precipitation. Might also improve their water quality and that of the nearby gulf.

More storm drains and reservoir capacity, perhaps. However it could be a long time before the combination of hurricane and blocking WX pattern recurs.
Maybe pumping water back into the ground to combat subsidence.

During the last hurricane to hit Houston, evacuation was ordered, and dozens died during that evacuation.
I suspect the mayor of Houston made the right call.

Reply to  Sixto
September 11, 2017 10:03 am

As a Houstonian, I think our Mayor is something of an idiot. But he made the right call here. Certainly evacuation of the city would have been (1) impossible without at least a week plus of lead time, (2) a waste of time and effort when the large majority of the city was not flooded, (3) resulted in far more deaths and injuries due to travel accidents than the few drowning deaths (almost all of which could have been avoided by reasonable behavior). If you watched the news channels, you might have thought all of Houston was flooded, in fact, a very small area was flooded – and a not insignificant amount of those areas had flooded before.

Anthony, wouldn’t it be interesting to crowdsource amateur(PWS?) wind data all along the coasts during weather events like Harvey and Irma? In particular, many amateur radio enthusiasts, who already provide emergency communications assistance in times of disaster, seem to routinely have antenna towers which would allow mounting at or close to the 10m height. Such an enormous body of information would be an incredible view of the variations in wind speeds with terrain differences, distance from coasts, storm centres etc and a useful balance to the seemingly sparse “official” numbers which always seem to disappear just when needed to counter the media silliness.

Now downgraded to 120mph/Cat 3 ahead of peninsula landfall.

Will believers castigate politicians for funding the rebuilding of the Florida Pennisula? If Mann and Gore chalk up the devestation to GW then shouldn’t the call be to just write off the loss and never fix any storm damaged areas within 50 miles of a tidal flat. End the federal flood insurance program, repurpose those funds towards building new communities high in the a
Appalachians. Why postpone the doom a hundred years hence?

Based on an analysis of AF306 Mission #30 into IRMA (this link will probably only be valid for a while) and the raw data file (ibid), I have done an analysis (which may be incorrect).
Briefly, the only surface wind data in the raw data file are peak (10 sec) winds in knots. Readings are reported every 30 seconds. I assume it is possible to approximate 1 minute sustained surface wind estimates by averaging two consecutive 30-second readings. There are two candidates:
11:56:30 89 knots
11:57:00 110 knots
Average would be 99.5 knots or about 115 mph, barely a Cat 4.
12:07:30 86 knots
12:08:00 97
12:08:30 98
12:09:00 97
12:09:30 92
12:10:00 89
12:10:30 83
12:11:00 79
The highest pair would give a 1 minute estimate of 98.5 knots or about 113 mph, a Cat 3.
Currently, Irma is rated a Category 3. It looks like the reported ratings are based on the SFMR readings, which are estimated surface winds speeds. From the whole flight, it appears that these speeds were only seen for about 3 minutes, disregarding those estimates that were higher but that had error flags or neighboring error flags (making them estimates of peak gusts not sustained speeds.)
There was a peak gust (albeit bracketed by error flags):
13:25:30 116 knots or about 134 mph

Sustained winds 43 knots at 4.18pm EDT recorded there. Radar showed the heaviest part of the eyewall at that time. Then the center of the eye with 5 knots 30 minutes later. The trailing side of the eyewall shows 31 knots.
On cable news a NHC expert says winds are “over 100” and Irma is “Category 2”
Live video of damage in Naples shows almost no palm tree damage but some fronds down in the streets. No damage to structures visible at that location. News reporter says some power is out, but the street lights behind him are obviously still working.
