LEONARDTOWN, Md. –  One of the biggest tidal flood events of the past 10-20 years (possibly since Hurricane Isabel at some locales), is expected Friday & Saturday.

Several Coastal Flood Warnings have been issued along the Chesapeake Bay and Tidal Potomac River. Water levels are already on the rise and will only rise more throughout the day today and into Friday. Tidal inundation levels of 2-4 feet are expected in low-lying coastal areas.

Coastal Flood Warning is issued for some parts of Virginia and Anne Arundel, Charles, St. Mary’s and Calvert Counties. The warning is in effect through 2 p.m. Saturday, Oct. 30, 2021

The potential for flooding is significant as the area is currently experiencing an increase in normal tides that will continue through Saturday’s high tide.

Additionally, due to tidal flooding, two to three feet of  inundation above ground level in low lying areas is predicted by the National Weather Service.

As a reminder, residents should now begin taking necessary actions to protect flood-prone property.

Citizens are encouraged to monitor weather conditions by visiting the National Weather Service website at http://www.nws.noaa.gov or listen to local radio stations.
