Memorial Day weekend weather: Flash flood watch issued in Baltimore area

As people across Maryland celebrate Memorial Day weekend, the National Weather Service on Sunday warning of possible flash flooding throughout the area.

Heavy rain drenched downtown Baltimore and much of the region Sunday afternoon, prompting some lanes closures amid dangerous driving conditions.

The weather service issued a flash flood watch for noon through 10 p.m. that applies to Baltimore, as well as some surrounding counties. Low-lying areas, especially near streams or other bodies of water, could be vulnerable to flooding.

Parts of northern Baltimore County were also under a tornado warning through 4 p.m.

Showers and thunderstorms are expected through the afternoon and evening, with rainfall of up to 3 inches. Sunday’s high is 82 degrees.

High water closed Route 1 at Ridgeley's Choice in both directions, the state highway administration tweeted at 2:42.

Monday is forecasted to be cooler and more clear, with highs near 80 and only a 30 percent chance of showers.

In Ocean City, slightly cooler temperatures are expected for the rest of the weekend. High temperatures are predicted in the mid-70s Sunday and Monday, according to the NWS.

There’s also a possibility of storms in the beach town, though — a 70 percent chance of showers Sunday night, according to the weather service. Thunderstorms are also possible Monday afternoon.
