Governor Hogan Declares State of Emergency for Counties Affected by Severe Weather, Tidal and Coastal Flooding

October 29, 2021

Governor Larry Hogan today declared a state of emergency for areas of Maryland along the shores of the Chesapeake Bay, the Potomac River, and the Atlantic Coast currently under a Coastal Flood Warning from the National Weather Service and therefore at risk of severe tidal and coastal flooding.

The state of emergency declaration includes Baltimore City and the following counties: Anne Arundel, Baltimore, Calvert, Caroline, Cecil, Charles, Dorchester, Harford, Kent, Queen Anne’s, Prince George’s, Somerset, St. Mary’s, Talbot, Wicomico, and Worcester.

According to the National Weather Service, the highest tides in 10-20 years are expected, with threats including the inundation of water on roads, sidewalks, docks, marinas, and residential and commercial areas.

“Even if you are accustomed to nuisance flooding, this is much more serious and has the potential to be much more damaging over the course of the next 24 hours,” said Governor Hogan. “We are taking this action to bring all necessary state resources to bear, and assist local jurisdictions in their response efforts. We urge Marylanders to remain vigilant, to stay tuned to local news stations for the latest updates, and to follow any instructions local officials may provide.”
