Some Maryland communities saw severe flooding on Thursday after storms brought heavy rain across the state. Several water rescues were reported in Harford County as flooding prompted road closures in some areas, like Joppatowne. In Mt. Airy, a child drowned after being washed into a drainage pipe during a heavy rainstorm on Thursday evening.

As heat and humidity increases in Maryland, so has flash flooding. The state has had at least 51 flash flood warnings so far this year, its most since 2020

Thursday will bring the fourth day in a row with a NEXT Weather Alert for the Philadelphia region, though it will be due to storms and flooding, not necessarily the heat. It will be hot, but it won't be as hot as the previous days.

Up to 5 inches (12.7 cm) of rain was forecast in the heaviest bands of showers expected across New York City, Long Island and the Hudson River Valley, with rainfall rates that could exceed 2 inches per hour, according to a statement from Hochul.

Flooding in New York City created a waterfall in the underground tunnels of the subway system on Thursday (July 31). New York Governor Kathy Hochul and her acting counterpart in New Jersey said they were declaring states of emergency for areas facing the threat of extreme flash floods forecast for much of the Eastern Seaboard.
