SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
DISORGANIZED SHOWERS AND THUNDERSTORMS ACROSS THE
FLORIDA PENINSULA EASTWARD TO THE ADJACENT WATERS OF THE
SOUTHWESTERN ATLANTIC OCEAN ARE ASSOCIATED WITH A WEAK SURFACE
TROUGH OF LOW PRESSURE. ENVIRONMENTAL CONDITIONS ARE FORECAST TO
BECOME MORE CONDUCIVE FOR DEVELOPMENT, AND A TROPICAL OR
SUBTROPICAL DEPRESSION COULD FORM IN THIS REGION OVER THE
WEEKEND
WHILE THE SYSTEM DRIFTS NORTHWARD OR NORTHEASTWARD. REGARDLESS
OF DEVELOPMENT, HEAVY RAINFALL IS POSSIBLE ACROSS PORTIONS OF
WEST-CENTRAL AND SOUTHWESTERN FLORIDA THROUGH EARLY SATURDAY,
AND ACROSS COASTAL SECTIONS OF THE CAROLINAS BEGINNING LATER ON
SATURDAY. AN AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT IS
SCHEDULED TO INVESTIGATE THE SYSTEM ON FRIDAY, IF NECESSARY.
THERE IS A MEDIUM CHANCE OF TROPICAL CYCLONE FORMATION WITHIN
THE NEXT TWO DAYS, AND ALSO THROUGH THE NEXT 7 DAYS.
