He was. I say 90L becomes Shary and 92L is Tomas...and then only 3 more to go until Greek if we bang these 2 out, and ACE will shoot up.

TWOAT
TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 AM EDT THU OCT 28 2010

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

SHOWER AND THUNDERSTORM ACTIVITY ASSOCIATED WITH A LOW PRESSURE
SYSTEM LOCATED ABOUT 1200 MILES NORTHWEST OF THE NORTHERNMOST CAPE
VERDE ISLANDS HAS BECOMES LESS ORGANIZED OVER THE PAST FEW HOURS.
SATELLITE DATA INDICATE THAT THE LOW IS PRODUCING WINDS TO GALE
FORCE. ALTHOUGH UPPER-LEVEL WINDS ARE ONLY MARGINALLY CONDUCIVE
FOR DEVELOPMENT...AN INCREASE IN ORGANIZATION COULD RESULT IN THE
FORMATION OF A TROPICAL STORM. THERE IS A MEDIUM CHANCE...50
PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS AS IT MOVES SLOWLY WESTWARD.

SATELLITE IMAGES AND SURFACE OBSERVATIONS INDICATE THAT A SURFACE
LOW IS FORMING WITHIN A DEEP-LAYER TROUGH LOCATED ABOUT 700 MILES
SOUTH-SOUTHEAST OF BERMUDA. SHOWER AND THUNDERSTORM ACTIVITY HAS
CHANGED LITTLE DURING THE LAST FEW HOURS. HOWEVER...ENVIRONMENTAL
CONDITIONS ARE BECOMING MORE CONDUCIVE FOR THE DEVELOPMENT OF A
TROPICAL OR SUBTROPICAL DEPRESSION DURING THE NEXT DAY OR TWO.
THERE IS A HIGH CHANCE...60 PERCENT...OF THIS SYSTEM BECOMING A
SUBTROPICAL OR TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT
MOVES WEST-NORTHWESTWARD NEAR 15 MPH.

A VIGOROUS TROPICAL WAVE LOCATED OVER THE TROPICAL ATLANTIC
ABOUT 1000 MILES EAST-SOUTHEAST OF THE WINDWARD ISLANDS IS PRODUCING
A LARGE AREA OF SHOWERS AND THUNDERSTORMS. ENVIRONMENTAL
CONDITIONS APPEAR FAVORABLE FOR SOME SLOW DEVELOPMENT OF THIS
SYSTEM DURING THE NEXT COUPLE OF DAYS. THERE IS A LOW CHANCE...20
PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS AS IT MOVES WESTWARD OR WEST-NORTHWESTWARD AT 15 TO
20 MPH.

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

Briefly talked with Richard Pasch and he's not impressed with this system at the surface.

That definitely has the look of a subtropical depression or storm. Perhaps 70% at 2 pm?

Clear LLC, convection near center. It all comes down to whether or not the NHC feels like naming it. Better chance of that due to the potential Bermuda threat.

I was talking with John Cangialosi and he said that this system may have a 36-hour window for development and that it has been improving. Nonetheless, at least 2 hours ago he told me that they haven't been able to completely close a LLC and that's the only thing missing for a subtropical or tropical depression or storm to form. I would guess that chances for development may increase at 2 pm.

Remains at 60%

SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A SURFACE LOW PRESSURE
AREA LOCATED ABOUT 600 MILES SOUTH-SOUTHEAST OF BERMUDA CONTINUE TO
SHOW SIGNS OF ORGANIZATION...HOWEVER THIS SYSTEM DOES NOT YET HAVE
A WELL-DEFINED CENTER OF CIRCULATION. ENVIRONMENTAL CONDITIONS ARE
SOMEWHAT CONDUCIVE FOR THE DEVELOPMENT OF A TROPICAL OR SUBTROPICAL
DEPRESSION OVERNIGHT OR ON FRIDAY...HOWEVER UPPER-LEVEL WINDS ARE
EXPECTED TO BECOME LESS FAVORABLE AFTER THAT. THERE IS A HIGH
CHANCE...60 PERCENT...OF THIS SYSTEM BECOMING A SUBTROPICAL OR
TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES
WEST-NORTHWESTWARD NEAR 15 MPH.
