Severe Thunderstorm Warnings, Watches Extended In N.J.

That rumble you may hear outside could be just the beginning.

The National Weather Service has issued a severe thunderstorm watch or warning through almost all New Jersey, extending the alerts until 9 p.m. Saturday.

Here is what to expect:

• HAZARD...60 mph wind gusts and penny size hail.
• SOURCE...Radar indicated.
• IMPACT...Expect damage to roofs, siding, and trees.

The watch means there is the potential for showers and thunderstorms, with winds gusting to more than 25 mph, according to the forecast from the Mount Holly office.

Heavy rain was falling in the Philadelphia area as of 5:15 p.m., according to social media reports, and radar from the National Weather Service shows a line of storms stretching from Delaware to New York moving east.

The potential for strong winds means you should tie down or bring inside anything that could get blown around during the storm.
