What the National Weather Service wrote

Two people were electrocuted in a stairwell going down into a basement that was flooded. Reports stated a portable sump pump was in the standing water in the basement.

The wider storm

Potent low pressure passed by to our west, and the warm front associated with the low moved through our area during this time. Warm and moist air near and south of the boundary led to an unstable atmosphere, while forcing from the warm front provided the lift. Thunderstorms developed and produced copious amounts of rainfall east of the Blue Ridge Mountains.

Began near Parkwood (39.0001, -77.0773).
