Rain Keeps Coming

A big storm complex is moving across the area early Monday. Rainfall totals have been in the 2 to 4 inch range from Baltimore southwestward to the Virginia suburbs of Washington, DC.

The rainfall will continue all night and localized flooding has become a problem. Flood Warnings are out for the counties surrounding Baltimore and Washington. A Flood Watch covers a larger area north and west of the Bay and will remain in effect through Monday afternoon.

On TV Hill, 1.12 inches of rain has been measured up to 12:45am Monday. Winds have been gusting well into the 20s all evening with a peak gust of 29mph. Winds have been gusting into the 40s on the Eastern Shore. Wind Advisories are out for the western shore of the Bay  and the central DELMARVA Peninsula and a High Wind Warning is in effect for the Southern DELMARVA Peninsula. A Storm Warning has been issued for the waters of the Chesapeake Bay.

The storm center is shifting from Ohio to the Atlantic coast and low pressure is intensifying over the lower Chesapeake Bay. At midnight the barometric pressure had dipped to 29.17 inches at Patuxent River Naval Air Station. Other low readings include Leonardtown, 29.22″; Cambridge, 29.25″; Ocean City, 29.30″; Annapolis, 29.32″; BWI-Marshall Airport, 29.37″.

Winds from the intensifying storm and the soaking rains over the past few days will likely bring down some trees due to the saturated ground. Scattered power outages are likely due to snagged power lines and soaked connections.

Small streams and creeks pose a hazard and will likely be running bankfull or higher Monday morning until the rain eases up.

On a historical note, the record rainfall in Baltimore for May 12 is 2.06 inches in 1921. If the rain keeps up a reasonable pace through the day that record could be threatened.

Be careful out there.
