SHOWERS AND LIGHTNING STORMS ARE EXPECTED TO FORM ALONG THE EAST COAST SEA BREEZE AS IT PUSHES ACROSS THE COASTAL AREAS AND WEST OF INTERSTATE 95 MID TO LATE AFTERNOON. THE PREVAILING SOUTHWEST WIND FLOW AND THE WEST COAST SEA BREEZE WILL KEEP THE EAST COAST SEA BREEZE FROM PENETRATING VERY FAR INLAND. THE TWO SEA BREEZES ARE EXPECTED TO COLLIDE BETWEEN SANFORD...ORLANDO AND OKEECHOBEE AND INTERSTATE 95 LATE AFTERNOON.

AS WITH ANY SEA BREEZE INTERACTION STORMS...SOME OF THE STORMS MAY PRODUCE FREQUENT TO EXCESSIVE LIGHTNING STRIKES AND WIND GUSTS IN EXCESS OF 50 MPH. LOCALLY HEAVY RAIN ASSOCIATED WITH SLOWER MOVING STORMS MAY PRODUCE TEMPORARY ACCUMULATIONS OF WATER IN POOR DRAINAGE AREAS AND RETENTION PONDS. AS STRONGER STORMS APPROACH THE COAST THERE MAY BE ENOUGH WIND SHEAR TO PRODUCE WEAK ROTATION IN THE LOWER PORTIONS OF THE CLOUD FOR FUNNEL CLOUDS AND WEAK TORNADOES TO FORM. OUTFLOW BOUNDARIES INTERACTING WITH EACH OTHER WILL KEEP TRIGGERING LIGHTNING STORMS UNTIL LATE EVENING. BOATERS ON INLAND LAKES AND RIVERS SHOULD KEEP AN EYE TO THE SKIES FOR APPROACHING WEATHER IN THE LATE AFTERNOON AND EVENING HOURS AND HEAD BACK TO SHORE IF STORMS ARE MOVING IN YOUR DIRECTION. ...RIP CURRENT IMPACT...
