800 AM EDT WED JUL 22 2009

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

DISORGANIZED SHOWERS AND THUNDERSTORMS SPREADING OVER THE
SOUTHEASTERN BAHAMAS AND HISPANIOLA ADJACENT WATERS ARE ASSOCIATED
WITH A TROPICAL WAVE MOVING TOWARD THE NORTHWEST AT 20 TO 25 MPH.
UPPER-LEVEL WINDS REMAIN UNFAVORABLE FOR DEVELOPMENT DURING THE
NEXT DAY OR SO. THERE IS A LOW CHANCE...LESS THAN 30 PERCENT...OF
THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

DISORGANIZED CLOUDINESS AND THUNDERSTORMS EXTENDING FROM THE
NORTHERN BAHAMAS NORTHWARD INTO THE ATLANTIC FOR SEVERAL HUNDRED
MILES ARE ASSOCIATED WITH A WEAK SURFACE TROUGH. SURFACE PRESSURES
ARE HIGH IN THIS AREA AND THERE ARE NO SIGNS OF ORGANIZATION AT
THIS TIME. THERE IS A LOW CHANCE...LESS THAN 30 PERCENT...OF THIS
SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

Still no word on the deactivation of 97L on NHC's web site. There should have been an update by now. Since there's nothing much left to track, I assume it's deactivated.

The little red "L" is gone from the S2K map above...

Bones has had enough of 97L. He says to watch the convection with the upper low north of the Bahamas. NHC will make that 98L within the next 6 hours:

[Sanibel]

Hey, has 97L turned into that thick swirl over the Haiti, Dominican border? If that is it the forward motion has slowed and looks like it is headed for Cuba if it maintains an identity.

Most of 97's moisture accelerated NW overnight and is now in the eastern Bahamas feeding into that upper low. The southern part of the wave continues to produce scattered convection over the DR west to Jamaica.

Time of death called?


edit looks like it

uh once again..another one bites the dust

[cpdaman]

well ....it was de-activated once already .......so

i think i can see some type of remant...rotation in the low clouds .....over haiti.....that may have finally started turning NW and then soon N as it is finally reaching a longitude where the steering turns more abrubtly from WNW to NNW...perhaps this will flow toward the area of decent 850 vorticity (just to the NW) and then be able to be the spark that gets whatever type of low will form ....to form.

[tailgater]

I don't know if this should be posted here or elsewhere but the wave that produced 97 can clearly be seen on the visible loop south of the Cayman Islands. Just something pretty to look at, almost no convection and lots of shear to the north and west.

Sorry about crude drawing it was first.

sooo....storm2k back on line

lots of low level convergence near central bahamas huge blob coming off cuba.......and the ULL moving a bit faster east of central florida looking like it may be filling.....any chance something is left in the bahamas thru/fri

also where this frontal low? latest marine forecast says developing late tonite just south of hatteras area
