E ATLC TROPICAL WAVE IS ALONG 24W/25W S OF 15N MOVING W 10-15 KT. SATELLITE IMAGERY INDICATES THAT A LOW LEVEL CIRCULATION MAY BE FORMING NEAR 11N25W. SCATTERED MODERATE/ISOLATED STRONG CONVECTION N OF THE POSSIBLE CIRCULATION FROM 11N-13N BETWEEN 25W-27W IS DISORGANIZED AT THE PRESENT TIME. ITCZ CONVECTION TO THE SW APPEARS TO BE CONNECTED TO THE OVERALL CIRCULATION. BROKEN/OVERCAST LOW/MID CLOUDS ARE SURGING NORTHWARD ON THE E SIDE OF THE WAVE AND MOVING OVER THE SOUTHERN CAPE VERDE ISLANDS. SHOWERS AND TSTMS WILL INCREASE NEAR OR OVER THE ISLAND CHAIN OVER THE NEXT 24 HOURS AS THE WAVE CONTINUES WESTWARD. CENTRAL ATLC TROPICAL WAVE FROM 20N50W-13N53W-6N56W MOVING W NEAR 20 KT. WAVE WAS REPOSITIONED SLIGHTLY TO THE W BASED ON 1200 UTC UPPER AIR DATA FROM GUYANA AND EARLY MORNING QUIKSCAT DATA. LEADING EDGE OF WAVE IS ABOUT 100-150 NM E OF BARBADOS AND THE REMAINDER OF THE WINDWARD ISLANDS. CIRCULATION ASSOCIATED WITH THE WAVE CONTINUES TO BE QUITE BROAD...EXTENDING E TO 45W AND W TO THE WINDWARD ISLANDS. EARLIER SURFACE LOW HAD DISSIPATED... ALTHOUGH A LOW-LEVEL CIRCULATION MAY STILL BE EVIDENT NEAR 12N51W. AN AREA OF SCATTERED MODERATE/ISOLATED STRONG CONVECTION IS W OF THE AXIS FROM 10N-13N BETWEEN 58W-62W. THIS CONVECTION WILL AFFECT THE WINDWARD ISLANDS DURING THE NEXT SEVERAL HOURS AS THE WAVE MOVES THROUGH THE AREA. Could These to devlop Easily Sence They Both Have Low-Level Circulation? |
