Tornadoes Possible As Severe Thunderstorm Watch Issued In Philly Area

Multiple tornadoes are possible Monday, the National Weather Service said, as a severe thunderstorm watch was issued for all of southeastern Pennsylvania Monday afternoon.

In addition to tornadoes and torrential rains, isolated, quarter-sized hail and 70 mile-per-hour winds are also possible.

A watch indicates severe impacts are possible. Warnings, which could be forthcoming later Monday, indicate they are imminent.

"Please take these storms seriously today," the National Weather Service's Mt. Holly, New Jersey branch shared.

It comes hours after a flood watch was also issued for the region. That watch went into effect at 2 p.m. The height of the storm is expected between 3 p.m. and 11 p.m.

Rain could fall at a rate of up 1 to 2 inches per hour, the National Weather Service said.

"While we are starting quiet this morning, the day will not end that way," the agency's Mt. Holly, New Jersey branch shared. "We still expect scattered severe thunderstorms along with some instances of flash flooding late this afternoon and this evening. Be weather-aware later today and tonight."

Poor drainage areas and urban areas at the highest risk of flooding.

The storms could impact the scheduled World Cup Game at Lincoln Financial Field today between France and Iraq. It's set for 5 p.m.

Officials say there is high confidence in the current forecast, with the whole region under a "level 2" risk, according to the National Weather Service.
