Tropical Storm Alberto

[Patrick99]

As far as I can tell, Alberto never had much convection wrapping around the center of circulation, if any....even during that burst early this morning. Maybe it should be classified as Subtropical Storm Alberto.

At any rate....next. Center still hasn't even made landfall, but all the storm activity is inland.

Am I crazy or did this storm suddenly disappear?

Looks like it just went POOF!

You're not crazy. Alberto's high clouds have evaporated (literally ) and I guess this loop is showing that. There's still a storm, of course, but it's more like the ordinary storms all over the map.

Unbelievably, the NHC is saying it has 70 mph winds still! I'm looking at buoys just north of the center with 25-30 kt NE winds. Haven't even seen a TS force wind in 4-5 hours.

Wait guys until the NHC really do say this has made an Extratropical transition, the last time we said something about Alberto's SAT presentation he became a 70 mph TS.

It's certainly transitioning. Of course you're absolutely right it could pop back up again if something gets convection going. And there were those odd mid-Atlantic storms over chillier waters last year, so it would be dangerous to say that's impossible.

Well that really doesn't mean this is now TD Alberto. ( Or does it?)

[Recurve]

It turned into a nor'easter right there in the nor'east Gulf.
It's like Alberto was only ever tropical on the right side.

It wants to be a monster gale off the outer banks.

Amending myself --> Pay attention to the NHC. It's a tropical storm and there are hurricane warnings up; don't let down your guard because of comments about weakening or being just a gale...

One other thing, please explain to me how this storm could possibly produce an 8-10 ft storm surge. Even if it had 70 mph winds, they'd be blowing from east to west on the northeast side of the storm - away from land. On the south and southeast side of the LLC the winds are SW 25-35 kts at best. That kind of flow will produce a setup tide of 2-3 feet at most. There just aren't any large areas of strong wind blowing toward the coast.

He looks like a ghost compared to what he was this morning—defiantly looking extratropical.

Storm Cancel..............Storm Cancel.............Storm Cancel...............
Better stop before it gets mad and becomes a hurricane against all odds.....

Probably not IMO. Winds are always higher than the buoy readings, for whatever reason. So if buoys are showing 25-30 the hurricane hunters will almost certainly find TS winds.

What did the dropsondes find, anyway?

That has me puzzled as well. I can see why they may not make any wholesale changes on the intermediate advisory, but there is absolutely no way this has 70mph winds. Heck, as you said, there are not even any reports of sustained tropical storm force winds.

I do expect some wholesale changes at 11pm.

One thing on the surge might actually be a combination of tides and surge. Here's the tide charts for Cedar Key.

Code: Select all

Tu  13     High   4:43 AM     3.2   6:32 AM     Set  8:05 AM      98
    13      Low   9:30 AM     2.0   8:32 PM    Rise 10:52 PM
    13     High   3:02 PM     4.5
    13      Low  10:36 PM    -0.6

That's about the only thing I can think of....

Nice RGB loop. Cetainly looked more impressive this morning. I think it could refire tonight a little.

[wxwatcher91]

no, either right now it is TS Alberto (Im not going to speculate exact wind speeds) or it is not tropical anymore.

my personal opinion is that it is no longer tropical. strengthening will likely take place overnight because of the diurnal cycle, but still I say it will not be tropical tomorrow either

[Noles2006]

I'm scratching my head trying to figure out the NHC's keeping Alberto at 70 mph for the intermediate advisory. Better safe than sorry, yes, but c'mon, let's be real here.

[King-6]

Check out this site and see if it's on a weakening stage...


Btw, Full moon phase.

Even if recon finds tropical storm force winds at flight level, it means very little. A storm needs convection in order to translate those winds to the surface and Alberto is void of any convection.

[jabber]

I would be shocked if he came back.....But not surprised

[WindRunner]

Not sure the details, but the 0000Z ob at SGOF1 reported 44mph winds, a good 85nmi north of the center. It's the "Tyndall AFB tower", offshore Appalachicola about 20nmi.

[Noles2006]

Honestly, I'd be extremely surprised if he came back this time.
