...SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING...
...A CHANCE OF RIP CURRENTS AT AREA BEACHES TODAY...

ANOTHER ROUND OF SCATTERED AFTERNOON AND EVENING THUNDERSTORMS IS
EXPECTED TODAY DUE TO AFTERNOON HEATING AND SEA BREEZE BOUNDARIES.
BY LATE AFTERNOON...SHOWERS AND THUNDERSTORMS WILL MOST LIKELY DEVELOP
INTO THE INTERIOR COUNTIES AS SEA BREEZE BOUNDARIES PUSH SLOWLY INLAND
DURING THE LATE AFTERNOON AND EVENING HOURS.

THE MAIN THREATS FROM THUNDERSTORMS WILL BE DEADLY CLOUD TO GROUND
LIGHTNING AND BRIEF WIND GUSTS TO 40 MPH. MOST LIGHTNING FATALITIES
AND INJURIES OCCUR IN OPEN FIELDS OR UNDER TREES. IF OUTDOORS...SEEK
SHELTER IN A STURDY BUILDING OR CAR. IN ADDITION...LOCALLY HEAVY
RAINFALL OF 1 TO 2 INCHES PER HOUR WILL BE POSSIBLE IN THE STRONGEST
STORMS WHICH COULD CAUSE MINOR FLOODING IN POOR DRAINAGE AREAS.

ALTHOUGH SOME STRONG THUNDERSTORMS ARE POSSIBLE...THEY ARE EXPECTED
TO BE BELOW SEVERE CRITERIA. THEREFORE SPOTTER ACTIVATION IS NOT
EXPECTED.

DUE TO SOUTHEAST SWELLS AND DEVELOPING ONSHORE WINDS...THERE IS A
CHANCE OF RIP CURRENTS. IF YOU ARE CAUGHT IN A RIP CURRENT...WADE OR
SWIM SIDEWAYS PARALLEL TO THE BEACH UNTIL YOU ARE OUT OF ITS PULL.
