1030PM TWO--- More concentrated....Pressures falling

TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
1030 PM EDT SUN JUN 12 2005

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

A BROAD SURFACE TROUGH IS PRODUCING WIDESPREAD CLOUDINESS AND
SCATTERED THUNDERSTORMS OVER THE CENTRAL CARIBBEAN SEA.
THUNDERSTORM ACTIVITY HAS BECOME A LITTLE MORE CONCENTRATED THIS
EVENING ABOUT MIDWAY BETWEEN JAMAICA AND COLOMBIA
...AND NOAA BUOY
REPORTS INDICATE SURFACE PRESSURES REMAIN LOW AND CONTINUE TO
SLOWLY FALL IN THIS AREA
. AS THE SYSTEM MOVES SLOWLY NORTHWESTWARD
...SOME SLOW DEVELOPMENT IS POSSIBLE OVER THE NEXT COUPLE OF DAYS
AS UPPER-LEVEL WINDS GRADUALLY BECOME MORE FAVORABLE.

A LARGE AREA OF CLOUDINESS AND SHOWERS IS LOCATED FROM THE
NORTHEASTERN CARIBBEAN SEA AND THE LEEWARD ISLANDS NORTHWARD OVER
THE ATLANTIC FOR SEVERAL HUNDRED MILES. THIS ACTIVITY IS DRIFTING
WESTWARD AND IS PRIMARILY ASSOCIATED WITH A LARGE UPPER-LEVEL
LOW. ENVIRONMENTAL CONDITIONS REMAIN UNFAVORABLE FOR TROPICAL
CYCLONE DEVELOPMENT TO OCCUR.

ELSEWHERE...TROPICAL STORM FORMATION IS NOT EXPECTED THROUGH
TUESDAY.

Interesting. In the shear in the area is under 10 knots. The area north of 20 north is where the shear is.

I checked the same bouy and the pressures had actually started to rise slightly (tendency was a .05 in rise as of 2 hours ago... which leads me to believe that the earlier falls were diurnal)

That said, they are VERY low for the area and I would not be surprised to see another depression within the next 24-48 hours

I'll give it a 60% chance of forming and a 40% chance of affecting the US--Leaning toward S Fla headed NE :eek:

On the cruise ship I was on they have a weather report every 10 minutes or so and I noticed that the pressures in the Caribbean are consistently below 1010 mb, in fact much of the time they were about 1006-1008 mb(except in Arlene where it was 1003 mb). Not sure what this means but the pressures are pretty low, ususally I would associate those pressures with TD's.

They have been low for a while which to me means, it wont take much to get a TD-though they are low over a broad area and there isnt any areas of high pressure to make any one area of pressure in the carib low--so does this still increase the chances??? You can have a TC develop in the middle of an area of High pressure and it could be like a 1000MB Hurricane if the pressures around it are high enough. We saw this a couple years ago.

I would think if the pressures are low=warmer then normal water. Which means tropical cyclones are going to form very fast. In might even become powerful.


I'm waiting for the invest. 8-)

I'm impressed with all the moisture from the west Caribbean to the central Atlantic. Something has got to pop.
