Multiple roads are flooded in Philadelphia, and the flooding could get worse on Friday night.
Flooded roads include Adm. Wilson Boulevard, seen from tweets by Kathy Orr of CBS.
Although there is no official flash flooding warnings or watches in place for Philadelphia, a meteorologist with AccuWeather says that Philadelphia is one of multiple big cities along the east coast that could be directly impacted by flash flooding going into Friday night.
“While most of the region will just experience a few doses of heavy rain and thunder, some locations can be hit much harder on one or more occasions through the end of the week,” said Alex Sosnowski, senior meteorologist with the website.
“A surge in humidity, combined with a very slow-moving front and a series of disturbances moving along it, will favor episodes of downpours, thunder and lightning,” he said.
Elsewhere in the state, areas including Allentown and Morristown are under a flash flood watch. Further up the East Coast, the Boston and Hartford metro areas, as well as Providence and Concord, are under a flash flood watch as well.
