Wind and tides trigger Coastal Flood Advisories
The National Weather Service has hoisted Coastal Flood Advisories (light green on map) for Maryland's Western Shore as the coastal storm developing to our south drives water into the tidal creeks and beaches.
The advisories are in effect from Harford County south to St. Mary's, from midnight until 6 a.m. They will then upgrade to a Costal Flood Watch, in effect through Saturday afternoon.
High tides could rise two feet above predictions overnight due in part to the persistent east winds, and in part because of increased tidal levels related to the approach of the new moon. Minor flooding is expected. Higher tides are expected on Saturday. Here's more from the NWS:
"STRONG EASTERLY WINDS WILL PERSIST THROUGH SATURDAY CAUSING TIDAL
ANOMALIES TO CONTINUE INCREASING. THE INCREASING TIDAL ANOMALIES
COMBINED WITH THE LUNAR CYCLE WILL BRING THE POTENTIAL FOR
MODERATE FLOODING NEAR TIMES OF HIGH TIDE.
"HIGH WATER LEVELS IN THE POTOMAC DUE TO HEAVY RAIN WILL ENHANCE THE THREAT FOR COASTAL FLOODING ACROSS THE UPPER TIDAL POTOMAC RIVER SATURDAY AFTERNOON
AND POSSIBLY INTO EARLY NEXT WEEK.
"EMERGENCY MANAGERS AND PEOPLE WITH INTEREST ON THE POTOMAC RIVER
AND THE WESTERN SHORE OF THE CHESAPEAKE BAY SHOULD BEGIN TO
PREPARE FOR POTENTIAL COASTAL FLOODING."
