Maryland weather: Flood warning in effect with thunderstorms, gusty winds expected

Baltimore is under a flood warning through 9:30 a.m. Monday, and a coastal flood advisory is in place for shoreline areas in southern Baltimore County and Baltimore City.

The National Weather Service said rain was likely before noon Monday and showers and thunderstorms were possible in the afternoon. Up to a quarter-inch of rain was expected Monday, followed by wet conditions throughout the rest of the week.

A coastal flood advisory was in effect for southern Baltimore County and Baltimore City through midnight Monday. The weather service said flooding was expected on Thames Street in Fells Point, on the Inner Harbor promenade at the dragon boat dock and in Bowley’s Quarters.

Coastal flooding was also expected along the Maryland portion of the Chesapeake Bay, including Anne Arundel, Charles and St. Mary’s counties, where the weather service warned severe thunderstorms Monday afternoon and evening could cause a tornado and flash flooding.

The weather service warned gusty winds up to 30 miles per hour paired with saturated ground could cause trees in the area to fall through Monday night, leading to blocked roads and power outages. The weather service urged residents of Maryland, Washington, D.C., and Northern Virginia to avoid driving through wooded areas, and suggested people who live near large trees consider staying in the lowest levels of their homes Monday night to protect themselves from falling trees.

Many roads around the region were closed because of high water, including State Route 450 between Huntwood Drive and Rutland Road in Anne Arundel County, Dock Street in downtown Annapolis and State Route 831 at Union Bridge Road in Carroll County.

In Annapolis, Dock Street and Compromise Street, between St. Mary’s and Newman streets, were closed Sunday night because of flooding, according to city agency tweets. City officials said Sunday evening Compromise Street reopened Monday morning, and Dock Street reopened with an alternate traffic pattern. Traffic from Eastport was able to reach downtown by Monday morning, but those traveling from downtown Annapolis were unable to reach Eastport via Compromise Street; police advised those travelers to use Duke of Gloucester Street.

More road closures were expected in Annapolis Monday afternoon with the high tide, according to the Annapolis Police Department.

Several state parks were closed because of tidal flooding, including the Avalon area of Patapsco Valley State Park and Point Lookout State Park.

Beaches were closed at Assateague State Park because of 12-foot waves and higher than normal tides. High tides and strong winds caused flooding Monday morning in Ocean City, and storms Sunday night blew large piles of sand onto the boardwalk.

Wind warnings were in effect on both the Bay Bridge and the Francis Scott Key Bridge.

More than 2 inches of rain had already fallen at Baltimore-Washington International Thurgood Marshall Airport from Saturday afternoon through 4 p.m. Sunday.
