ATL: ALBERTO - Post-Tropical

[Hurricane Andrew]

The link does work, RL3AO.
May 19,2012, first renumber of the 2012 atlantic hurricane season.

Looks like 93L is shooting out a ton of outflow boundaries to the S over the past couple of hours... I wonder if the convection will collapse soon.

Ive soon many tiny systems like this spin up rather quickly only to fall apart a few hrs later. The NHC will generally classify a disturbance as a TC when the system has maintained persistant deep convection close to its COC for a period of at least 12 hours, combined with a Westerly wind of 25 knots or greater, if a "closed" COC has been detected using aforementioned satellite tools, recon, or surface obs from land based stations, ships and/or buoys.

edit! Hello Alberto

[CrazyC83]

IMO, if they decided it is a tropical storm now, it was a TS at 1200Z as well.

Welcome to the 2012 Atlantic Hurricane Season!!!!

Even if the calendar suggests otherwise...

Off Topic= The formation of TS Alberto will count for the S2K 2012 poll so those who are on the list or are thinking of posting numbers until May 31rst,be aware about that.

This thing looks like a TS. Seems like an EL Nino Year, early development from non-tropical means...

First time the Atlantic and Pacific basins have both had a named storm in May since 2008.

Earliest time both basins have at least 1 tropical storm (not counting Central Pacific storms).
Counting them, 1992 would be the earliest when a storm formed in the Atlantic in late April.

kinda shocked at the special TWO at 11am was only 50% chance.

[CrazyC83]

When was the last time there was a HURRICANE before June 1?

[RL3AO]

They'll probably wait until 2100z. No point releasing a full advisory at 20z then having to do it all again, an hour later.

I agree.

Not sure, Crazy...but this is from the 17Z run of the HRRR Rapid Refresh (considered experimental):



This is showing forecast 10 meter winds in knots for 23 UTC this evening

[cycloneye]

This is the first named pre-season storm since May 31st, 2008 with Tropical Storm Arthur.

[cycloneye]

Anyone who may be wondering why Cycloneye does not change the title of thread to TS Alberto? That is because we wait for the official word by NHC. I dont remember what year it was but I changed a title from invest x to TD x,finding out later that they didn't upgrade.

When was the last time there was a HURRICANE before June 1?

I took the time to manually go through the files and found the last time we had a hurricane before June 1 was in 1970 with Hurricane Alma:

Just a matter of time until the first official advisory.

[txwatcher91]

Any ideas how the low pressure to the north, off the coast of VA, may affect 93L? It would seem as it slowly drifts southward that there would be some type of influence, positive or negative, upon 93L?

[Evil Jeremy]

Welcome to hurricane season folks!!! Is this the quickest we have gone from invest to named storm?

[Aric Dunn]

well looking at TPW. seems some moisture is starting to spread back north out of the carribean and into the gulf. alo tof the dry air has receded or been pushed back the western gulf. also to note the motion of the system over the last 24 hours. ridging to the nw and be stuck in the a baroclinic zone has aided the system thus far.

And it's gone from the map!! Just a matter of time...
