[wxwatcher91]

8pm TWD we have a 1008mb low!
...plus 4 other waves to talk about
...TROPICAL WAVES...

TROPICAL WAVE LOCATED ABOUT 100 NM W OF THE AFRICAN COAST ALONG
18W/19W S OF 19N MOVING W 5-10 KT. A 1008 MB LOW IS LOCATED
ALONG THE WAVE ABOUT 70 NM NW OF DAKAR NEAR 15N18.5W BASED ON
WIND AND PRES OBSERVATIONS FROM NEARBY SHIPS AND LAND STATIONS.
THE WAVE IS DEVELOPING A WELL-DEFINED SIGNATURE WITH MID-LEVEL
CLOUDINESS BEGINNING TO "SPILL OVER" THE WAVE AXIS FROM THE
E...AND CONVECTION BEING ORIENTED ALONG A LINE FROM S OF THE
CAPE VERDES NEWD INTO W/CNTRL MAURITANIA. SCATTERED
MODERATE/STRONG INLAND OVER WRN MAURITANIA AND SENEGAL FROM
13N-22N BETWEEN 11W-17W. OTHER DEEP CONVECTION IS FARTHER W
ALONG THE ITCZ. SHOWERS/TSTMS ARE EXPECTED TO MOVE OVER THE CAPE
VERDE ISLANDS ON FRI AND SAT AS THE WAVE PASSES BY.

TROPICAL WAVE ALONG 35W S OF 16N MOVING W 15-20 KT. THE WAVE IS
LOW-AMPLITUDE AND ENSHROUDED BY DRY AIR TO ITS N...BUT A SMALL
CLUSTER OF SHOWERS AND TSTMS HAS BEEN MAINTAINED ALONG THE ITCZ
AND PROGRESSING TO THE W WITH SOME SORT OF MID-LEVEL
CIRCULATION. SCATTERED SHOWERS/TSTMS FROM 8N-13N BETWEEN 35W-41W.

TROPICAL WAVE ALONG 50W S OF 16N MOVING W 15 KT. THIS WAVE IS
NOT VERY WELL-DEFINED AND ACTUALLY APPEARS TO BE ASSOCIATED WITH
AN EASTERLY WIND SURGE...WHOSE LEADING EDGE IS ALONG 10N45W
20N54W. THERE IS NO ASSOCIATED CONVECTION WITH THIS WAVE.

EAST CARIBBEAN TROPICAL WAVE ALONG 65W/66W S OF 20N MOVING W
15-20 KT. THE WAVE IS EMBEDDED WITHIN WEAK FLOW S OF T.S. IRENE
BUT STILL THERE IS AN INVERTED-V SIGNATURE NOTED IN VISIBLE AND
SHORTWAVE INFRARED IMAGERY S OF THE VIRGIN ISLANDS. SCATTERED
MODERATE CLUSTERS OF CONVECTION ARE LOCATED OVER NRN VENEZUELA.

WEST CARIBBEAN TROPICAL WAVE MOVING INLAND OVER CENTRAL AMERICA
ALONG 84W S OF 20N MOVING W 20 KT. INSTABILITY ASSOCIATED WITH
THE WAVE IS INCREASING THE COVERAGE AND INTENSITY OF SEA BREEZE
CONVECTION WHICH HAS DEVELOPED FROM ERN HONDURAS TO NRN COSTA
RICA. NUMEROUS MODERATE/STRONG CONVECTION FROM 9N-16N BETWEEN
83W-86W.

I'm glad NHC decided to mention this feature. I think we'll see development in the next couple of days even if it develops slowly.
