On-and-off showers soaked the D.C. region Saturday before turning heavy in the evening.
The National Weather Service predicted cooler temperatures, rain showers and plenty of clouds across the D.C. area as a frontal boundary remains stalled to the west. Some storms slowed traffic on Route 50 in Prince George’s County, Maryland, as drivers navigated floods along the highway.
WTOP Traffic reporter Steve Dresner said off-and-on high-standing water was also causing slow traffic along the northbound lanes of the Baltimore-Washington Parkway between Route 50 and The Beltway.
He said drivers who travel too closely to each other can expect road spray to interfere with visibility.
7News First Alert Meteorologist Jordan Evans said Saturday will be “damp and dreary,” with rain chances “staying at 100% throughout the day.”
He expects a quarter-inch of rainfall during the day, with another quarter-inch to a half-inch before Sunday morning.
While the National Weather Service forecasts low chances of a thunderstorm Saturday night, rain is expected to become more intense, with “unsettled weather” continuing Sunday.
The weather service issued a Coastal Flood Advisory for D.C. from 4 p.m. Saturday until 9 a.m. Sunday, with shoreline inundation expected “along portions of the seawall adjacent to Ohio Drive and the Hains Point Loop Road and near the Tidal Basin.”
Tides are expected to be “one to one and a half feet above normal,” according the National Weather Service, while noting next high tide at the Washington Channel is between 5:44 p.m. Saturday and 6:09 a.m. Sunday.
Evans said to expect “a few rumbles of thunder” on Sunday.

A warm front should lower the risk for severe weather on Monday and clouds will stick around the D.C. region, according to the National Weather Service. But Evans said the chance for more showers and thunderstorms rise later in the day.
He said increased heat and humidity “may bring a few storms, some strong,” to the D.C. area on Tuesday. But added that the “risk for severe weather is low,” for now.
Thunderstorm chances are expected “to increase mid week,” according to the National Weather Service.
