The National Weather Service has issued a tornado watch for 10 New Jersey counties, saying conditions are ripe for the development of isolated tornadoes as strong thunderstorms sweep through the state Tuesday evening and into the night.
The tornado watch is in effect until 10 p.m. and covers Burlington, Camden, Gloucester, Hunterdon, Mercer and Warren counties. Nearly all of Pennsylvania is also included in the watch.
Update 5:45 p.m.: The tornado watch has been expanded to include four more counties in New Jersey: Atlantic, Cape May, Cumberland and Salem.

Although a watch is not as urgent as a warning, the weather service says atmospheric conditions are conducive for small tornadoes to form. If any funnel clouds are spotted, or if forecasters notice rotating winds on weather radar, the watch will likely be upgraded to a tornado warning.

— Go to an enclosed area in the center of the building and stay as low as possible, away from glass.
