SW N ATLC...
REMNANT OF ANDREA CONTINUES TO CHURN OFF THE NE FLORIDA COAST 
NEAR 29N80W. A PULSE OF CONVECTION WAS FLARING NEAR THE CENTER 
OF THIS SYSTEM THIS MORNING...BUT IS DISSIPATING CURRENTLY. A 
MORNING QUIKSCAT PASS SHOWED WINDS UP TO 30 KT ON THE SE 
QUADRANT OF ANDREA IN THE CONVECTION. OBSERVATIONS FROM 41010 
AND 41009 AS WELL AS QUIKSCAT DATA SHOW 20 TO 25 KT AROUND THE 
SYSTEM. BUOY 41009 WAS REPORTING A 1007 MB PRES AS WELL JUST W 
OF THE CENTER. JUDGING FROM COASTAL RADAR IMAGERY...THE CENTER 
APPEARS TO STILL BE DRIFTING SLOWLY S. HOWEVER...SHORT WAVE 
ENERGY DIGGING THROUGH THE OHIO VALLEY WILL PUSH OFF THE MID 
ATLANTIC STATES TOMORROW. THIS WILL PROMPT A COLD FRONT INTO THE 
WATERS OFF NE FLORIDA AND N OF THE BAHAMAS BY SUN. AS A 
RESULT...THE LOW IS PROGGED TO LIFT OUT TO THE NE STARTING 
TONIGHT. SEAS WILL REMAIN NEAR THE 9 TO 10 FT RANGE FOR THE MOST 
PART AROUND THE LOW TODAY...THEN DIMINISH AS THE LOW MOVES OUT 
OF THE AREA THROUGH SAT. WINDS AND SEAS WILL PICK UP BEHIND THE 
FRONT STARTING SUN NIGHT.

CARIBBEAN AND TROPICAL N ATLC...
A TROUGH REMAINS IN PLACE ALONG ROUGHLY 80W S OF CUBA IN THE 
WESTERN CARIBBEAN. BUOY 42058 NEAR 15N75W WAS REPORTING 20 KT 
SUSTAINED...INDICATING THAT THE GRADIENT IS INCREASING BETWEEN 
THE TROUGH TO THE W AND A SURFACE RIDGE THAT IS NOSING INTO THE 
EASTERN CARIBBEAN FROM THE CENTRAL ATLC. THIS WILL REMAIN THE 
GENERAL PATTERN THROUGH THE WEEKEND. LIGHT TO MODERATE FLOW WILL 
PERSIST OVER THE FAR WESTERN CARIBBEAN ALONG AND W OF THE 
TROUGH. STRONGEST WINDS REMAIN JUST N OF THE VENEZUELAN AND 
COLOMBIAN COASTS.

GULF OF MEXICO...
WEAK 1015 MB HIGH PRES IS CENTERED OVER THE NW GULF. THE HIGH  
WILL SHIFT A LITTLE S TONIGHT...AHEAD A WEAK TROUGH IS EXPECTED 
TO PUSH INTO THE NW GULF. HOWEVER...GIVEN THE WEAK PRES 
PATTERN...WINDS AND SEAS WILL REMAIN LOW THROUGH THE WEEKEND 
ACROSS THE CENTRAL AND WESTERN GULF. IN THE EASTERN GULF...THE 
BACK DOOR COLD FRONT IS EXPECTED TO PUSH INTO THE NE GULF WATERS 
LATE SUN...FOLLOWED BY MODERATE TO FRESH NELY WINDS. SMOKE FROM 
FIRES OVER N FLORIDA AND S GEORGIA MAY LIMIT VISIBILITIES TO 2 
MILES OR LESS OVER PORTIONS OF THE NE GULF TODAY AND TONIGHT.
