WASHINGTON — Saturday has been hot and humid with storms and showers rolling into the D.C. area, causing flooding and prompting weather warnings.

Following the rain in the late afternoon, the D.C.-area saw severe weather in isolated areas, prompting warnings from the National Weather Service.

NWS issued a severe thunderstorm warning for Prince George’s County and Montgomery County in Maryland, and in Southwestern Culpeper County in Virginia.

NWS issued a flash flood warning for Fauquier and Culpeper counties and north central Rappahannock County in Virginia.

The D.C. area and areas to the north saw showers and a few thunderstorms.

Although there was not a severe threat, heavy, blinding downpours were a primary concern that could lead to localized flooding, as Storm Team4’s Somara Theodore had forecast.

The threat of rain will linger throughout the D.C. area for much of the weekend, but the good news is the weather will be a bit cooler. Temperatures will top out in the mid 80s for the most part.

Theodore said that Monday looks like the best day of the holiday weekend, with temperatures in the low 80s and some sun, although there is still the chance for rain.

If you’re planning on traveling out of the D.C. area to the Gulf Coast, a storm could wind up causing some travel problems.

The National Hurricane Center said tropical storm conditions might wind up reaching parts of the Gulf Coast as soon as midday Sunday. This is due to Subtropical Storm Alberto, which could strengthen over the course of the weekend.

Alberto is the first named storm of the 2018 Atlantic hurricane season, which doesn’t officially start until June 1.

You can track the storm on the National Hurricane Center’s website.

Storm Team 4 Meteorologist Chuck Bell said depending on what track the storm takes, it could have an impact on the weather in the D.C. area by the second half of next week in the form of soaking rains and potential flooding.
