D.C. Area Gets One Month's Worth of Rain in One Day

Wednesday's heavy rainfall brought a month's worth of rain to the D.C. area in just 24 hours.

All three area airports broke rainfall records, with Dulles International Airport receiving 3.99 inches of rain, Baltimore-Washington International Airport receiving just over 3 inches and 2.7 inches of rain pouring down at Regan National Airport.

Storm Team4's Tom Kierein says some smaller creeks and streams will begin to recede Thursday, but major rivers in the area will remain at or above flood level. At 22 feet, the Rappahannock River at Fredericksburg was four feet above flood level Thursday, making moderate flooding a possibility.

In Laurel, Md., a leaking joint on the dam on the Patuxent River began to pour water onto a nearby construction site. Concerns that the water would cause erosion around the buttress that supports the dam prompted the opening of the floodgates and evacuations in some areas.

The evacuation was lifted around 8 a.m. Thursday

According to WSSC, two Fort Washington facilities are experiencing sewer overflow, though the spill shouldn't affect drinking water. Schools in Culpeper County and Charles County were on a 2-hour delay Thursday, May 1.

Rescue crews in both Virginia and Maryland spent most of Wednesday pulling stranded drivers to safety. In Prince George's County, crews rescued a driver of a white SUV after a portion of the vehicle became submerged in Bowie.

A tanker driver was pulled to safety in Loudoun County after he became stranded in flood waters.

In Leesburg, drivers were forced to make U-turns where small secondary streets were flooded in low-lying areas.

"I've got to go a half-mile out of the way; not a problem," said one driver on Shreve Mill Road, where a stream swallowed up the one-lane bridge not far from the Dulles Greenway.

The fast-moving water collected logs and other debris, so road may be a mess even after the floodwaters recede.

The system that found its way to the D.C. area was the same one that produced severe weather in the mid-Mississippi Valley, but it changed as it moved east.

Expect dry and mild weather heading into the weekend.
