Rain set at least one record by Sunday afternoon, but it kept pouring, causing high water, closed roads, puddles, flooding and worries about flooding.

The record was set at Dulles International Airport, where 1.64 inches of rain had fallen by 4 p.m., beating the 44-year-old record by more than half an inch. Records at Dulles go back only to the 1960s.

Another half-inch of rain fell at Dulles, raising the total for the day there to more than 2 inches.

Many roads flooded in Loudoun County, as creeks and small streams overflowed.

Waters rose in many other places, including the 5900 block of MacArthur Boulevard and part of Broad Branch Road in Northwest Washington, northbound lanes of Interstate 295 near Benning Road NE, and southbound lanes of the interstate near Overlook Avenue SW.

Particularly heavy rain was reported in Prince William County and areas west of Washington. One Fairfax resident wrote on the Washington Post's Capital Weather Gang blog of being "scared of what I might find in my basement."

A Prince William resident wrote, "I've never seen such big floods."
