A WEAK COLD FRONT EXTENDS FROM NEAR 31N77W TO
INLAND THE FLORIDA COAST NEAR VERO BEACH. A PRE-FRONTAL TROUGH
EXTENDS FROM NEAR 28N78W SOUTHWESTWARD TO INLAND SOUTH FLORIDA.
A SHORTWAVE TROUGH ALOFT SWINGING EASTWARD ACROSS NORTHERN AND

REACHING FROM NEAR 31N76W TO THE NW BAHAMAS AND TO SOUTH FLORIDA
BY LATE TONIGHT. ELSEWHERE, HIGH PRESSURE OVER THE CENTRAL
ATLANTIC CONTINUES TO MAINTAIN CONTROL OVER MUCH OF THE WESTERN
ATLANTIC WHILE ROUGH SEAS PREVAIL OVER THE SE WATERS. ANOTHER COLD
FRONT IS EXPECTED TO ENTER THE NORTHERN WATERS EARLY NEXT WEEK
AND GRADUALLY SHIFT SOUTHEASTWARD AND WEAKEN. FRESH TO NEAR GALE-
FORCE EASTERLY WINDS AND ROUGH TO VERY ROUGH SEAS, PEAKING TO
AROUND 14 FT, ARE FORECAST BEHIND THE FRONT MON THROUGH TUE NIGHT
