Tidal Flooding

Large ocean swells combined with Southerly winds today kept water levels above average in the Chesapeake Bay. Coastal Flood Warnings and Advisories are issued for the Chesapeake Bay coasts through Thursday morning. Tides are running about 1-2 feet above average, so minor tidal flooding is possible around times of high tide. The area most prone to this looks to be Southern Dorchester County. But all the usual flood prone spots around the Bay have the threat for tidal flooding through early Thursday morning.

Another storm will approach Delmarva late Thursday into Friday providing another chance for some tidal flooding along the Bay. There looks to be a period of onshore flow that may keep water levels high as well as any runoff from any rainfall that occurs. It is possible the flood advisories and warnings could be either extended or re-issued sometime on Thursday. Some good news though as the storm passes by Friday night. There will be a stronger offshore wind For Saturday which will help push the water back out into the Ocean and lower water levels.
