SITUATION OVERVIEW
------------------
TROPICAL STORM CHANTAL WILL MEANDER CLOSER TO THE SOUTHEAST U.S.
COAST TODAY AND TONIGHT, MAKING LANDFALL ALONG THE MIDDLE AND UPPER
SOUTH CAROLINA COAST SUNDAY MORNING.
AS CHANTAL NEARS THE COAST, BREEZY NORTHWEST WINDS WILL OCCUR AS THE

FORECAST TO REMAIN THE STRONGEST ALONG THE SOUTH CAROLINA BEACHES,
WITH GUSTS AROUND 40 MPH POSSIBLE. IN ADDITION, WIND GUSTS ACROSS THE
ELEVATED BRIDGES AROUND THE CHARLESTON METRO AREA MAY EXCEED 45 MPH AT
TIMES TODAY.
RAIN BANDS WILL PUSH ONSHORE ALONG THE COAST OF THE SOUTH CAROLINA
LOWCOUNTRY THIS MORNING AND CONTINUE INTO TONIGHT. THESE BANDS MAY
DRIFT SLOWLY INLAND AS THE SYSTEM NEARS THE COAST BRINGING AS MUCH AS
1 TO 2 INCHES OF RAIN. THE RAIN MAY BECOME LOCALLY HEAVY AT TIMES,
RESULTING IN FLOODING, MAINLY IN LOW-LYING AND POOR DRAINAGE AREAS.
HEAVY RAINFALL COULD OCCUR DURING THE LATE AFTERNOON HIGH TIDE,
POTENTIALLY INCREASING THE RISK OF FLOODING ACROSS COASTAL COMMUNITIES
AND LOCATIONS NEAR TIDAL WATERWAYS LATE THIS AFTERNOON INTO EARLY THIS
EVENING. THIS INCLUDES DOWNTOWN CHARLESTON. WIDESPREAD FLASH FLOODING
IS UNLIKELY AT THIS TIME.
NEARING LANDFALL, THERE IS A CHANCE OF WATERSPOUTS FORMING WITHIN
THESE RAINBANDS OVER THE NEARSHORE CHARLESTON WATERS AND POTENTIALLY
MOVING ONSHORE OVER EXTREME NORTHERN CHARLESTON COUNTY THROUGH TONIGHT
INTO SUNDAY MORNING.
GUSTY WINDS AND BUILDING WAVES WILL RESULT IN STRONG RIP CURRENTS
ALONG THE SOUTH CAROLINA AND GEORGIA COAST THROUGH THIS WEEKEND. IN
ADDITION, BEACH EROSION AND HIGH SURF WITH BREAKERS OF 4 TO 6 FEET
COULD OCCUR ALONG THE BEACHES OF CHARLESTON COUNTY.
