When Danielle becomes a major hurricane this week, Richard Holle’s prediction will be confirmed as exact to date.
Oh Mon petit Danielle, you are so far and so weak!
I am going to stick with 7 major storms, 50 percent tropical storms and 50 percent hurricanes.
Chances are it won’t make shore.
Cat 2 to 3 Possible..

Told ya.
From the earlier thread:
And just imagine the excitement that’ll ensue in the newsrooms if the prediction holds for it to become a major hurricane by midweek.
So, did they declare it a hurricane without flying a single Herculese through it, again? Al Gore needs to lend the Atlantic some viagra if we are going to get anything with potential for serious rapage.
Meanwhile TS Frank weakens…. http://www.nhc.noaa.gov/index.shtml
NOAA predicts….
14-20 Named Storms,
8-12 Hurricanes
4-6 Major Hurricanes
They have a ways to go. I wonder what kind of odds one could get in Vegas on their predictions being right?
So, “48-hour formation potential” – formation of what exactly? A tropical depression, a named storm, etc.?
Dr. Hansimian’s forecast of 6-8 hurricanes appears to be on track.
Estimated intensity of 3 mph less keeps this storm below hurricane category 1. Watch NOAA closely when it estimates/forecasts storm intensity of these mid-Atlantic storms without actual measurements from airplanes. It always increases the estimate above the hurricane category threshold when nobody can take a real measurement.
I was off by 3 days for date of second named hurricane of the season in the comment below made almost two weeks ago.
http://wattsupwiththat.com/2010/08/10/klotzbach-on-atlantic-hurricane-season-analysis/#comment-454057
Now for the hurricanologist he can cull his list of hurricane seasons to those with a La Nina and the second hurricane coming in the last week of August, recalculate his ACE average for those conditions, and update his forecast for the rest of the season.
In fact, since the list of those hurricanes is included in the OP for the Klotzbach thread referenced above I just added them up for myself. There are nine seasons on record with a La Nina and the second named hurricane happening on or after August 22. The seasonal average ace for those years is 129.7
In the comment above I made almost two weeks ago I predicted this season’s ACE to come out at, wait for it now, one hundred twenty nine.

Dr. Hansimian’s forecast of 6-8 hurricanes appears to be on track.
so true, and you know, Dr. Hansimian would work for bananas literally, compared to all the data crunchers we have that can not even get close.
But you really never know to be honest.
Oh look!
I think I see where the NOAA forecast got hurt. A La Nina that had grown very weak to almost moderate in July 2010 at 0.94 cooler SST than neutral weakened a whole bunch since then. It’s expected to persist through November but it sure isn’t very significant on the power scale so far.
I believe the theory goes (correct me if I’m wrong) that La Nina in the pacific reduces wind sheer at some critical altitude where tropical depressions form in the Atlantic and where the reduced wind sheer allows the depressions to more easily spin up into an organized storm.
Invest 96L (Red cherry drop on the map) may become Earl within the next few days…
“MAXIMUM SUSTAINED WINDS HAVE INCREASED TO NEAR 75 MPH…”
Near enough to ‘call it’ in time for the evening news …
.
The CO2-hurricane frequency/strength relationship has been adequately debunked. Don’t waste any time or breath on it.
The season is normal (within typical range) and some may make it to landfall. That we have reasonable warning (advance notice) is the key.
That anyone wants to make a CAGW issue out of it is just grist for our mill. 🙂
Looks like a hurricane to me http://www.ssd.noaa.gov/goes/flt/t1/avn-l.jpg This is not a temporary whirl with no staying power, it has good symmetry and outflow.

I voted for two named storms, one really weak one around the 20th to 23rd, and a stronger one later forming around the 25th and making landfall Florida panhandle close to end of month, 30th or 31st.
Or this one?;

Made a my space blog comment on the updated forecast I posted on WUWT “thoughts on the 2010 hurricane season.”
2010 detailed Hurricane forecast
Current mood: adventurous
Today I climbed out on a big limb, with chainsaw in tow, with this forecast?
There are four ingredients needed to make a large storm, available heat energy, moisture to change phase states to generate the low pressure zone, ion potentials to drive the “precipitation” (not just condensation), and a global lunar tidal effect to drive the wind patterns that tighten up, as the tropical air mass that becomes the tropical storm, moves off of the ITCZ and further away from the equator, the Coriolis effect kicks in and strengthens, to assist the formation of the cyclonic circulation along with the associated ionic drives.
We have been having three of these ingredients showing up in the three named disturbances so far. However the global “pole to equator ion charge gradient” is currently stagnating, all of the seasonal drivers of these shifts in charge gradients will occur later in the year than is the”Normal” (although nonrandom pattern of distribution.)
The solar cycle has been slow, but is starting to pick up as we approach the heliocentric conjunctions of three of the four outer planets that drive the global ion potentials that create and drive these large storms. I have posted a detailed forecast of the dates to expect these storms to be produced several time over the past year.
Due to the geomagnetic effects of the increased coupling, of the solar fields extended out from flares and coronal holes, as the Earth passes through the focused area that lines up heliocentrically with the outer planets:
Neptune on the 20th of August, the Earth will have an increased homopolar generator charge potential inducted into it, then relaxed over the next two weeks (till end of August 2010) that will induce the typical discharge pattern that generates the large flows of ions that allow the global tropical storms to attain sizable effects above cat 1 – cat 2 levels, because of increased wind and precipitation production, powered by the enhanced action of the opposing ion charges swept into the cyclonic flow structure.
September 21st through 24th 2010 will see the bigger set of conjunctions that will do a much better job of driving the intensity of resultant global tropical and extra-tropical storms, that form on the discharge side of the ion flux patterns, after these dates. No the season is not over yet.
The lunar declinational tides that peak at the culmination of the declinational sweep occur at Maximum South on 19th August then heads North with tropical moisture in tow until the effects has run its course by the 2nd to 4th of September 2010, is the window of opportunity for the first weaker outbreak of global TS.
The lunar declination is Maximum South again on the 15th of September 2010, ahead of the peak of charging of the Uranus / Jupiter heliocentric conjunction of the 24th of September 2010, and it should be in phase with the movement of tropical moisture laden warm air crossing the equator following the moon, as it moves North across the equator on the 23rd of September.
The same day of the peak charging effects of the homopolar generator as the Earth responds to the increased inductive effects carried on the solar wind to affect the coupling through to the outer planets from the sun out of a large coronal hole created on the sun just for the purpose of providing the magnetic field energy needed. This powers up the cycle of positive ion charging along the ITCZ, by pushing more moisture into the lower atmosphere, to then add drive to the ion discharging phase, driving the resultant outbreak of global wide intense tropical storms, that will occur post conjunction.
By the time the Moon reaches maximum North declination on the 29th of September 2010, the global ACE values will be close to peak for the year. Inertial momentum of the global systems should carry on the enhanced zonal flow through the next two weeks.
With the continual decreasing electromagnetic coupling as the Earth moves past these outer planets the severe weather activity levels, will drop with continued attempted recovery enhancements at the lunar declinational culminations, until by the time of the synod conjunction of Venus and Earth on the 29th of October 2010, we will see a last hurrah, then a slow shift into the storms of a deep cold NH winter.
That’s what they said (NOAA), unfortunately, in this ‘numbers’ game (and in a game where both the ‘prediction’ and ‘call’ are made by the same party) things could be/may be too easily ‘rigged’ to achieve a/the desired outcome (high or targeted score) … perchance you don’t see/don’t grasp this?
Where are the ‘refs’, the auditors on this/on this one (the hurricane count in light of/versus NOAA’s ‘predictions’)?
Certainly _not_ a case of ‘nothing but net‘ if all your hurricanes come in at or NEAR (as NOAA seems to have called this one; see bulletin above in posted article) 75 MPH wind speed from the __low__ side …

Generally it’s expressed as El Niño causing shear; neutral and La Niña don’t affect the Atlantic as much. I don’t have a good feel for just how the transition goes. La Niña’s cooler SSTs impact Pacific storms, but I don’t follow those as closely as Atlantic storms.

I believe the NOAA prediction is for the Atlantic season, Frank is an eastern Pacific storm and doesn’t count against the NOAA prediction.
Along with my long held contention that, “Summer is hotter than Winter.” I also have come to the astonishing conclusion that, ” Hurricanes occur mainly during the Hurricane season.”…. I know, I know. Controversial stuff. But I gotta call it as I see it fellas;-)
She’s a very healthy looking CAT 1, no doubt.
[As everyone knows….no two Saffir-Simpson children are the same!].
Good anticyclonic outflow in all quadrants, symmetric, buzz-saw appearance of the central dense overcast, wisps of cirrus being pulled away at high altitudes and in all directions from the thunderstorms in all directions, as if with an artist’s brush..

With warms SST’s and favorable upper-level conditions in its path…
Whaddaya bet it becomes a strong CAT 4 within 24 hours?

Looks like Danielle will miss my home, which is all I care about during hurricane season. i also like to read the discussion from hurricane center more than the warnings, gives you a little better sense of what is really happening. http://www.nhc.noaa.gov/text/refresh/MIATCDAT1+shtml/232033.shtml?

So, did they declare it a hurricane without flying a single Herculese through it, again?
Looks that way. It’s located at some 40°W, some 2400 miles from the US.
According to http://www.hurricanehunters.com/mission.html their coverage area only goes out to 55°W. See http://www.hurricanehunters.com/mission.html
Long ways to go for a minor event. Not very fast planes, no in-flight refueling ability.
http://www.nhc.noaa.gov/text/refresh/MIATCDAT1+shtml/232033.shtml says “Dvorak T-numbers have risen to T4.0 from TAFB and SAB…and Danielle is upgraded to a hurricane on that basis.” T-numbers are assigned from analysis of satellite imagery, see http://en.wikipedia.org/wiki/Dvorak_technique .
From the NHC Discussion…
“the convective canopy of Danielle has become more axisymmetric over
the past few hours…indicating that vertical shear over the system
is now relaxing. A 1620 UTC AMSR-E microwave pass showed a distinct
low-level center of circulation that is displaced a little to the
southeast of the mid-level center of rotation. Despite that
structure…Dvorak T-numbers have risen to t4.0 from TAFB and
SAB…and Danielle is upgraded to a hurricane on that basis. The
cyclone appears to be going through a period of rapid
intensification…”
Danielle and future Earl are both currently projected to spin far away from the US. More disappointing news for those waiting for the second-coming of Katrina (their Messiah).
Blow, winds, and crack your cheeks! rage! blow!
You cataracts and hurricanoes, spout
Till you have drench’d our steeples, drown’d the cocks!
You sulphurous and thought-executing fires,
Vaunt-couriers to oak-cleaving thunderbolts,
Singe my white head! And thou, all-shaking thunder,
Smite flat the thick rotundity o’ the world!
Crack nature’s moulds, an germens spill at once,
That make ingrateful man!
