Hurricane Florence's outer bands could bring some rain to Maryland this weekend, and the edges of its wind field could create coastal flooding along the western shore of the Chesapeake Bay.
High tides could be as much as 2 feet above normal in Anne Arundel, Calvert, St. Mary’s and Charles counties Friday night through Saturday. An easterly flow from the hurricane and a high-pressure system helping steer it are expected to push waters on shore.
A coastal flood warning is in effect for Anne Arundel from 6 p.m. Friday through 6 p.m. Saturday. Significant flooding was expected in Annapolis.
“Water is expected to come up through storm drains, approaching businesses on Dock Street in Annapolis,” the National Weather Service warned. “Water is expected to approach the Maritime Museum and begin to cover Bowyer Road at the Naval Academy.”
As much as a couple of inches of rain are possible across Southern Maryland, National Weather Service meteorologists said. But most of the region will be spared of significant rain or effects from Florence.
Less than a quarter of an inch of rain was expected Friday in the Baltimore area, and wind gusts could reach 20 mph. Cloudy conditions are forecast to continue into Saturday, but with diminishing winds and rain chances as Florence moves southwest away from the mid-Atlantic.
Isha Renta, a meteorologist with the weather service’s Baltimore/Washington forecast office, said there could be threats of isolated flooding where persistent storms and rain set up.
“There could be some amounts of heavy rain associated with the outer bands of the storm,” she said. “Some of them could carry heavy amounts of rain, and some of them could be lighter.
“We cannot discount them,” she added. “Sometimes these systems, they expand. We have to keep watching.”
By Sunday, with Florence expected to be a tropical depression centered over inland South Carolina, chances for showers in Maryland are expected to lessen. The sun could even come out.
Local meteorologists were already looking ahead to next week, when the remnants of Florence, by then expected to be a tropical or post-tropical depression, could move into the Mid-Atlantic.
The National Hurricane Center forecasts it could be centered over southwestern Pennsylvania by early Tuesday morning. There could be a threat of flooding in Western Maryland and along the Blue Ridge, the weather service said.
