SYNOPSIS FOR ALTAMAHA SOUND GA TO FLAGLER BEACH FL OUT TO 60 NM-
150 PM EDT MON JUL 21 2025
SYNOPSIS
A TROUGH WILL CONTINUE TO DROP ACROSS THE LOCAL WATERS TODAY LEADING
TO AN INCREASE IN OFFSHORE FLOW, KEEPING THE ATLANTIC SEA BREEZE
MOSTLY PINNED ALONG THE COAST THIS AFTERNOON. SHOWERS AND
THUNDERSTORMS WILL BEGIN TO MOVE INTO THE LOCAL WATERS DURING THE
AFTERNOON HOURS AND LINGER INTO THE OVERNIGHT HOURS INTO TUESDAY.
WEAK LOW PRESSURE MAY DEVELOP NEAR OUR LOCAL WATERS ON TUESDAY, WITH
COVERAGE OF SHOWERS AND THUNDERSTORMS INCREASING THROUGHOUT OUR
LOCAL WATERS. STRONG TO ISOLATED SEVERE THUNDERSTORMS MAY DEVELOP ON
TUESDAY AND WEDNESDAY, WITH STRONG WIND GUSTS, FREQUENT LIGHTNING
STRIKES, AND TORRENTIAL DOWNPOURS POSSIBLE. WEAK LOW PRESSURE SHOULD
SHIFT TO THE WEST OF OUR AREA BY LATE IN THE WEEK, ALLOWING FOR
ATLANTIC HIGH PRESSURE TO BUILD WESTWARD TOWARDS OUR LOCAL WATERS.
COVERAGE OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO DECREASE BY THE
WEEKEND AS SOUTH-SOUTHEASTERLY WINDS PREVAIL.
