Severe storms hammered parts of the tri-state area Monday afternoon into the late evening hours, flooding City subways, prompting dozens of water rescues and triggering a state of emergency in hard-hit parts of New Jersey.

The National Weather Service has issued flash flood watches for parts of 17 New Jersey counties on Monday to start a stormy week.

The heat advisory includes parts of Delaware, Pennsylvania, New York, Connecticut and New Jersey, where two people died in flooding.

Flash flooding, possible severe storms and heat risks will be in effect for Delaware on July 16 and 17. See the weather forecast.

New Jersey is expected to miss the heaviest rainfall in the latest round of thunderstorms on Tuesday, but more flash flooding is possible.

Just one day after a fast-moving storm swept through New Jersey, causing dramatic rescues, a home explosion, and multiple deaths, officials have issued both a Flood Watch and Heat Advisory for the region.

Footage shows wooden slats from the home on the ground with other debris. The blast took place around the same time heavy rainfall hit the northeast.
