I wonder if it was ever completely tropical to begin with. :P

this info was from supplementary data - it may be the NOAA flight out there -I'm not for sure. BUT the coordinates are right for this storm.

To what value would that translate to the surface?
If this is correct, if the value is 0.8 then the storm has winds of 64.8 knots right? of course all of that is based on if these winds are actually making it to the surface...


With such a hybrid storm, the wind reduction may be considerably more than .75, right Derek? a number of buoys are passing right through the heavier squalls and reporting 35 kts.

At 8:07 am EDT today, I wrote
It sure looks to me like Alberto is trying very hard to relocate the circulation center to the ENE, judging simply by the very symmetrical and outstanding appearance of the convection that is ENE of where the last recon indicated the center was located.

Am I alone in seeing this? Is the an illusion, or a real possibility?

At 11:00 am EDT today, NHC wrote
THE AIR FORCE HURRICANE HUNTER PLANE FOUND THAT THE CENTER OF THE CYCLONE HAS ABRUPTLY REFORMED NEAR THE DEEP CONVECTION...AND IT IS NOW RELOCATED SOME 60 N MI TO THE NORTHEAST OF ITS PREVIOUSLY ESTIMATED POSITION.

I guess sometimes there really is a payoff when you go with your gut instinct on these things. But more times than not, there won't be.

I've been watching that ship. I am not sure if that's a 1 minute wind and if the ship is reporting the wind correctly. Ship wind are notoriously bad, depending upon how the equipment is maintained and the experience of the observer. Hard to measure winds while moving.

I'm sure TPC will look into it.

reduction should still be .75 from this altitude since they are so low. Now, where the NOAA aircraft was flying, maybe a .7 or even a .6 reduction is appropriate, which is why the 81KT did not equate to a hurricane

Derek, you have to admit, this is one strange storm. Doesn't even look like a TS on satellite. Looks like a mess.

definately does not look like a TS. Looks awful. Tampa radar is a bit better though. Shows the storm definately accelerating to the NE

It looks alot like Earl from 98.

I don't see it making Hurricane strength and with the shear separating the LLC from the mid and upper it may take a more northerly jog once again.

Don't ship also usually forget to deduct for distance above sea level?

Here's a plot of satellite & SFC reports near Alberto. I think that buoy 72nm NE of the center has a 34 kt ENE wind It's in an area of diminishing squalls. That's the strongest I've seen it hit as the squalls went through.

Storm surge, storm surge, that's what all the fuss is about here in Citrus County. This feels much like the No Name Storm of '93.

Reminds me of Hurricane Earl in 1998. Even at his Category 2 peak, Earl looked NOTHING like a hurricane.

Without a well-defined core, there won't be much of a surge.
