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.

A state of emergency has been declared in New Jersey, while New York subway stations were flooded. Flash flood warnings were issued in Pennsylvania and Virginia.

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.

Flash flood warnings were issued by the National Weather Service Monday night as heavy storms rolled into the area. Flood warnings were issued for Morris, Warren, Bergen, Essex, Hunterdon, Hudson, Passaic, Middlesex, Somerset and Union Counties, according to the National Weather Service.

A Flood Watch has been issued for a significant portion of New Jersey. The watch is in effect from Wednesday afternoon through late Wednesday night, as forecasters warn of the potential for flooding due to excessive rainfall.

Heavy rains and flash flooding in the northeast have caused two deaths in New Jersey. More rain is expected through mid-week for portions of the eastern and central U.S.

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.

On Wednesday at 5:36 p.m. the National Weather Service released a flash flood warning in effect until 8:45 p.m. for Bedford, Blair, Cambria and Somerset counties.
