Possible Tornado, Coastal Flooding Advisory in Effect over Baltimore as the Week Starts

Baltimore is under a coastal flood advisory until Monday night, according to the National Weather Service. Along with this, there is a chance of storms and damaging winds on Monday, as well as a possible tornado event.

The area is being covered by large patches of dense fog, which could cause delays to morning commutes.

Up until 10 AM on Monday, flooding along the shore could happen in southern Baltimore County and Baltimore City. According to the NWS, low-lying areas could experience flooding of up to half a foot, especially during high tide.

This afternoon, a cold front will pass through, bringing with it showers and thunderstorms that could produce up to 3 inches of rain and create a risk of flash flooding. A flood watch is in effect for portions of the counties of Anne Arundel, Howard, Carroll, Montgomery, Harford, Baltimore, and Prince George's.

An advisory for coastal flooding is in place in Annapolis until 9 PM. Monday's high tide was 3 feet above average at 7:15 AM, flooding the City Dock parking lot. Minor flooding is also being caused by the Severn River.

As of 9:12 PM on Sunday, flooding was occurring at the end of Thames Street in Fells Point, and water was almost completely covering the promenade at the dragon boat dock in the Inner Harbor. By 8 PM on Sunday, the Baltimore region had accumulated a little bit more than an inch of rain.

With heavy rain predicted for Monday afternoon through the evening, additional flooding for the area is possible.

The NWS warned on Sunday that thunderstorms expected on Monday could increase the chance of a tornado or strong winds. The storm may produce a waterspout as it crosses the Chesapeake Bay.
