* Flash flood warning for Northwest Prince George’s County until 7 p.m.*

5:10 p.m. – High seas rescues reported in central Prince George’s County after 3 inches of rain in just over an hour

A slow-moving thunderstorm with torrential rain moved through north-central Prince George’s County and dumped more than 3 inches of rain just north of Landover, triggering a flash flood alert. The National Weather Service reported that the Prince George’s County Fire and Rescue Service was deploying boats to perform water rescues along MD-201 Kenilworth Avenue between MD-450 Annapolis Road and MD-410 Riverdale Road. “Seven vehicles were stranded,” the weather service wrote. “The police have closed the road.”

The causative thunderstorm moved south and southeast of the flash flood warning area and weakened somewhat.

Still, keep an eye out for the weather until tonight as with the air so humid, widely scattered storms could continue to unleash heavy rain and cause some localized flooding issues.

We picked up another 90 degree day and high humidity made it feel even hotter. Heat indices were around 100 this afternoon. Almost instant sweat, then lots more to follow. High temperatures mixed with high humidity to bring some intense showers and thunderstorms to the area this afternoon. They will fade with the sunset. We start all over again on Tuesday.

A few storms could be strong to severe, with the main threat outside being lightning, heavy rain and isolated damaging winds. Before any rain, temperatures will head into the low and mid-90s.
