2. A CONCENTRATED AREA OF CLOUDINESS AND THUNDERSTORMS CENTERED ABOUT
1000 MILES EAST-NORTHEAST OF THE LEEWARD ISLANDS IS ASSOCIATED WITH
A TROPICAL WAVE INTERACTING WITH AN UPPER-LEVEL LOW. ALTHOUGH THERE
ARE NO SIGNS OF A SURFACE CIRCULATION...UPPER-LEVEL WINDS COULD
BECOME A LITTLE MORE CONDUCIVE FOR DEVELOPMENT DURING THE NEXT DAY
OR TWO. THIS SYSTEM HAS A LOW CHANCE...20 PERCENT...OF BECOMING A
TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES
WEST-NORTHWESTWARD AT ABOUT 10 MPH.

The topic related to this area that was at Talking Tropics forum.

This one isn't much of a development or impact threat. It's heading out to sea into high shear and cooler water.

SSD Floater is up.

[TropicalAnalystwx13]

This will probably become at least a tropical depression before becoming absorbed in 5-6 days. It will be entering an area of lower wind shear and it has more model support at this time today than it did yesterday.

CLOUDINESS AND THUNDERSTORMS CENTERED ABOUT 1000 MILES

8 PM Special Feature Discussion:

TROPICAL WAVE EXTENDS FROM 22N48W TO A 1009 MB LOW AT 17N46W TO
13N42W MOVING W AT 10-15 KT. A 1536 UTC OSCAT IMAGERY DEPICTS
THE LOW CENTER WELL. A STRONG WIND FIELD WITH E TO NE WINDS IN
THE RANGE OF 20 TO 25 KT...IS WELL N OF THE LOW CENTER. THIS
AREA CLOSELY MIRRORS AN AREA OF SCATTERED MODERATE CONVECTION
FROM 20N-24N BETWEEN 40W-51W AND IS LIKELY ENHANCED BY UPPER
LEVEL DIFFLUENCE DUE TO AN UPPER LEVEL LOW CENTERED NEAR 19N50W.
THIS SYSTEM HAS A MEDIUM CHANCE OF BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS.

SHOWER ACTIVITY LOCATED ABOUT 850 MILES EAST-NORTHEAST OF THE

Remains at 30%.

A TROPICAL WAVE INTERACTING WITH AN UPPER-LEVEL LOW IS PRODUCING A
SMALL AREA OF SHOWERS AND A FEW THUNDERSTORMS OVER THE CENTRAL
ATLANTIC ABOUT 850 MILES EAST-NORTHEAST OF THE LEEWARD ISLANDS.
ENVIRONMENTAL CONDITIONS ARE EXPECTED TO BE CONDUCIVE FOR SOME
DEVELOPMENT BEFORE UPPER-LEVEL WINDS STRENGTHEN ON TUESDAY. THIS
SYSTEM HAS A MEDIUM CHANCE...30 PERCENT...OF BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES NORTHWESTWARD TO NORTH-
NORTHWESTWARD AT ABOUT 10 MPH.

[cycloneye]

I know all the attention is and has to be for 99L,but let's not forget this invest. IMO,it looks close to TD status.

[TropicalAnalystwx13]

The only part of the criteria of a tropical cyclone 90L does not currently met is persistent convection. However, if the shower and thunderstorm activity that it fired about two hours ago continues to persist, then I could see this attaining TD status at 11pm EDT. Not that the NHC will declare it..they'll come up with some excuse of why it doesn't deserve a name, like Patty.

40% now.

A TROPICAL WAVE INTERACTING WITH AN UPPER-LEVEL LOW IS PRODUCING A
SMALL AREA OF SHOWERS AND A FEW THUNDERSTORMS OVER THE CENTRAL
ATLANTIC ABOUT 750 MILES EAST-NORTHEAST OF THE LEEWARD ISLANDS.
ENVIRONMENTAL CONDITIONS ARE EXPECTED TO BE CONDUCIVE FOR SOME
DEVELOPMENT BEFORE UPPER-LEVEL WINDS BECOME LESS FAVORABLE ON
TUESDAY. THIS SYSTEM HAS A MEDIUM CHANCE...40 PERCENT...OF
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES
NORTHWESTWARD TO NORTH-NORTHWESTWARD AT ABOUT 10 MPH.

[Florida1118]

Maybe it doesn't have a surface circulation? Not sure why they are holding back on it...

[CrazyC83]

The models seem to like this one too? Sandy and Teddy in the days ahead?

You mean't Tony.

[Florida1118]

SHOWERS AND THUNDERSTORMS HAVE BECOME A LITTLE BETTER ORGANIZED NEAR
A SMALL AREA OF LOW PRESSURE OVER THE CENTRAL ATLANTIC ABOUT 700
MILES EAST-NORTHEAST OF THE LEEWARD ISLANDS. ENVIRONMENTAL
CONDITIONS ARE EXPECTED TO BE CONDUCIVE FOR DEVELOPMENT BEFORE
UPPER-LEVEL WINDS BECOME LESS FAVORABLE ON TUESDAY. THIS SYSTEM
HAS A MEDIUM CHANCE...50 PERCENT...OF BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS AS IT MOVES NORTHWARD AT ABOUT 10 MPH.
