SYNOPSIS FOR THE GULF OF AMERICA
1029 PM EDT SAT JUL 18 2026
SYNOPSIS
BROAD LOW PRESSURE HAS FORMED OFFSHORE OF TAMPA BAY,
FLORIDA NEAR 84.5W, AND WILL DRIFT NORTHWARD OVER THE NEXT FEW
DAYS, BRINGING THUNDERSTORMS AND HEAVY RAINFALL TO THE NE GULF AND
ADJACENT PORTIONS OF FLORIDA. GRADUAL DEVELOPMENT OF THIS SYSTEM
IS POSSIBLE AND A TROPICAL DEPRESSION COULD FORM OVER THE NEXT
FEW DAYS BEFORE THE SYSTEM MOVES INLAND ACROSS THE FLORIDA
PANHANDLE. REGARDLESS OF DEVELOPMENT, MARINERS SHOULD PREPARE FOR
THUNDERSTORMS PRODUCING LOCALLY GUSTY WINDS AND HIGHER SEAS. AWAY
FROM THIS SYSTEM, WEAK HIGH PRESSURE WILL DOMINATE, PRODUCING
GENTLE TO MODERATE WINDS AND SLIGHT TO MODERATE SEAS THROUGH THE
PERIOD.
