.DISCUSSION...A WEAK RIDGE OF HIGH PRESSURE WILL BUILD ACROSS
SOUTH FLORIDA TODAY WITH A VERY WEAK SOUTHWEST WIND FLOW AT THE
FIRE SITE. A SEA BREEZE WILL DEVELOP ALONG THE SOUTHWEST COAST AND
PUSH SLOWLY INLAND BUT WILL VERY LIKELY REMAIN TO THE SOUTHWEST OF
THE FIRE. THIS WILL RESULT IN SOUTHWEST WIND OF LESS THAN 5 MPH,
BUT COULD REACH UP CLOSE TO 10 MPH IF THE SEA BREEZE MOVES INLAND
FAR ENOUGH. THERE WILL BE SCATTERED SHOWERS AND THUNDERSTORMS
DEVELOPING ALONG AND AHEAD OF THE SEA BREEZE EARLY THIS AFTERNOON
AND THEIR MOVEMENT WILL BE SLOW AND ERRATIC DUE TO THE VERY LIGHT
STEERING FLOW.
