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 THE 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 MOVES LITTLE.
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.
