SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A WEAK COLD FRONT WILL MOVE OFF THE SE U.S COAST THU
NIGHT, THEN STALL OVER THE FAR NW BASIN FRI INTO THE WEEKEND. AN
AREA OF LOW PRESSURE COULD DEVELOP NEAR THE SOUTHEAST U.S.
ATLANTIC OR GULF COASTS BY THIS WEEKEND ALONG A WEAKENING
FRONTAL BOUNDARY. ENVIRONMENTAL CONDITIONS APPEAR ONLY
MARGINALLY CONDUCIVE FOR SOME SLOW DEVELOPMENT, BUT A TROPICAL OR
SUBTROPICAL DEPRESSION COULD FORM IN THIS REGION OVER THE
WEEKEND OR EARLY NEXT WEEK WHILE THE SYSTEM DRIFTS NORTHWARD OR
NORTHEASTWARD. REGARDLESS OF DEVELOPMENT, HEAVY RAINFALL IS
POSSIBLE ACROSS PORTIONS OF THE SOUTHEAST U.S., PARTICULARLY
ACROSS THE WEST- CENTRAL FLORIDA COAST. THERE IS A MEDIUM CHANCE
OF TROPICAL FORMATION THROUGH THE NEXT 7 DAYS.
