ON NEXRAD 88D...SCATTERED SHOWERS AND THUNDERSTORMS WERE MOVING FROM WEST TO EAST ACROSS THE CENTRAL PENINSULA. AS THIS ACTIVITY CONTINUES TOWARD THE EAST COAST A FEW CELLS WILL MOVE OVER THE INTRACOASTAL AND NEAR SHORE ATLC WATERS. MARINERS NEED TO KEEP AN EYE TO THE SKY WESTWARD AS POTENTIAL THREATENING WEATHER APPROACHES. STILL A WAIT/SEE APPROACH AS TO WHETHER THE ECSB DEVELOPS ALONG EITHER THE SPACE/TREASURE COASTS. IF IT DOES IT WILL LIKELY REMAIN PINNED ALONG THE COAST...BUT COULD HELP TO INTENSIFY EXISTING CONVECTION AS IT MOVES OFF OF THE COAST. MAIN THREATS REMAIN TORRENTIAL DOWNPOURS...FREQUENT LIGHTNING AND LOCALLY STRONG WIND GUSTS UP TO AROUND 50 MPH. ELSEWHERE...THE SURFACE RIDGE AXIS REMAINS WELL SOUTH OF ECFL. EXPECT SHOWERS/STORMS TO LINGER INTO THE EVENING ALONG THE TREASURE COAST BEFORE DIMINISHING BY MIDNIGHT.
