LESSEN ON THURSDAY, BUT WILL STILL LIKELY HAVE WIND SPEEDS AROUND 15
MPH ALONG THE COAST, WITH OCCASIONAL GUSTS NEAR 30 MPH. DRIER AIR

THE ATLANTIC WILL ADVECT INTO THE AREA. SCATTERED TO NUMEROUS
CHANCES ARE EXPECTED AS DIURNALLY DRIVEN SHOWERS AND STORMS DEVELOP
OVER THE WEEKEND. COASTAL LOCATIONS WILL LIKELY CONTINUE TO SEE
HIGHER RISK OF RIP CURRENTS DUE TO THE PERSISTENT ONSHORE FLOW
THROUGH THE WEEKEND. BY THE UPCOMING WEEK THE OVERALL FLOW WILL VEER
TO BECOME SOUTHEASTERLY-SOUTHERLY BY MIDWEEK. HIGHER CHANCES OF
PRECIPITATION LIKELY TO CONTINUE AT THE START OF THE NEW WEEK AS
