SYNOPSIS
A STRONG TROPICAL WAVE, MOVING NEAR THE NE CARIBBEAN
WILL PROMOTE A NORTHEASTERLY WIND FLOW TONIGHT, BECOMING MORE
EAST-SOUTHEAST TO SOUTHEAST SAT AND SUN. THE CHANCE TO OBSERVE
SHOWERS AND THUNDERSTORMS ACROSS THE ISLANDS LATE TONIGHT INTO
SAT WILL INCREASE, DRYING RAPIDLY LATE SAT EVENING INTO SUN. A
LONG PERIOD NORTHERLY SWELL FROM DISTANT EXTRATROPICAL CYCLONE
ERIN WILL SPREAD ACROSS THE ISLANDS FROM NOW ONWARD, RESULTING IN
HAZARDOUS SEAS FOR THE ATLANTIC WATERS AND CARIBBEAN PASSAGES
THROUGH EARLY NEXT WEEK. MEANWHILE SHOWERS AND THUNDERSTORMS HAVE
NOT BECOME ANY BETTER ORGANIZED THIS EVENING IN ASSOCIATION WITH
A TROUGH OF LOW PRESSURE, AL90, LOCATED A COUPLE HUNDRED
NAUTICAL MILES NORTHEAST OF THE NORTHERN LEEWARD ISLANDS.
ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR FURTHER DEVELOPMENT
OF THIS SYSTEM, AND A TROPICAL STORM IS VERY LIKELY TO FORM THIS
WEEKEND WHILE IT MOVES NORTHWESTWARD AND THEN NORTHWARD OVER THE
SOUTHWESTERN ATLANTIC.
