A sprawling Eastern storm, the second in a week, will soak the Mid-Atlantic and Northeast brought wind-driven major coastal and tidal flooding, the highest seen in 18 years in some areas.

An expansive low-pressure system spun over the Ohio Valley, with a broad area of rain rotating around it from the Great Lakes and Mississippi Valley to the Tennessee Valley to the mid-Atlantic and Northeast.

Several days of onshore winds from an earlier nor'easter kept water levels elevated along the coast, bays, etc.

Renewed strong easterly winds pushed water into bays and inlets of the Mid-Atlantic on Oct. 29-30.

Coastal flooding began Friday's (Oct. 29) high tide in eastern Virginia's "Northern Neck", south of Washington, D.C., according to video posted to social media.

In Annapolis, Maryland, flooding surpassed levels seen only in Hurricane Isabel and an August 1933 flood, putting the city's boardwalk at the city dock underwater. Flooding also closed streets and sidewalks.

And some homes and structures were reportedly taking on water at Solomon's Island, about 50 miles southeast of Washington, D.C. at the mouth of the Patuxent River, according to Calvert County emergency management.

Along Delaware Bay at Reedy Point, Delaware, south of Wilmington, the bay's crest fell just short of the record from April 2011, in records dating to at least 1980.

In the Washington, D.C. metro, a pair of high tides Friday and early Saturday morning in Alexandria, Virginia, were exceeded only by Isabel and a March 1936 flood, inundating lower portions of several streets.

Friday afternoon's high tide flooded and closed the George Washington Parkway south of Alexandria, something WTOP Radio reported was rare. Water inundated The Wharf in D.C. requiring workers to use boats to navigate, WTOP reported.
