Severe storms were developing around the Baltimore region Friday evening, as meteorologists already warned of high tides expected to inundate shorelines from Annapolis to Baltimore.
Severe thunderstorm warnings were posted for parts of Carroll, Howard and Baltimore counties through 5:30 p.m., and meteorologists said more storms were possible around the region.
Before any storms, rainfall since Thursday afternoon was already approaching 2 inches at Baltimore-Washington International Thurgood Marshall Airport on Friday. It was enough to have the region’s point of record on the verge of surpassing 70 inches of precipitation for all of 2018 by Friday morning.
It is already Baltimore’s wettest year on record. The region surpassed the old record, 62.66 inches from 2003, in November.
Coastal flood advisories were in effect along the western shore of the Chesapeake Bay. High tides are expected to rise 2 feet above normal.
The National Weather Service said tides could inundate City Dock, approach the Maritime Museum and begin to cover Bowyer Road at the U.S. Naval Academy in Annapolis; at the end of Thames Street in Fells Point and on the dragon boat dock in the Inner Harbor in Baltimore; and in the Bowley’s Quarters area of Baltimore County.
Earlier Friday, streams were flooding across Baltimore and Harford counties, the National Weather Service said. A flood warning was in effect across much of Harford and Baltimore counties through 9:30 a.m. Stream gauges along Gunpowder Falls indicated that flooding was imminent in Glencoe, where summer rains also caused repeated inundations.
The storms came after temperatures surged into the lower 60s around the region Friday. That is about 20 degrees warmer than normal for this time of year. Colder air was pushing its way back into the region Friday night, expected to bring dry and seasonably cold weather is forecast through Christmas.
