THE HIGHEST COVERAGE IS EXPECTED ACROSS THE TREASURE COAST INTO OKEECHOBEE COUNTY WHERE LOW LEVEL MOISTURE REMAINS HIGHER AND IN CLOSER PROXIMITY TO UPPER LEVEL SUPPORT.

VISIBILITIES MAY CHANGE QUICKLY OVER A SMALL AREA. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY. A SMALL THREAT FOR LIGHTNING STORMS WILL EXIST MAINLY ACROSS THE INTERIOR INTO MID-WEEK DUE TO SEA BREEZE INTERACTIONS. .SPOTTER INFORMATION STATEMENT...
