“At 9:33 p.m., a severe thunderstorm capable of producing a tornado was located over Basking Ridge, or near Morristown, moving southeast at 30 mph.," the National Weather Service stated.

“Take cover now. Move to a basement or an interior room on the lowest floor of a sturdy building. Avoid windows. If you are outdoors, in a mobile home, or in a vehicle, move to the closest substantial shelter and protect yourself from flying debris.”

A tornado warning indicates that severe weather is imminent in the area or is already occurring.

Ten counties were placed under a tornado watch on Tuesday afternoon as the storms began to barrel west from Pennsylvania to the Garden State.
