New Jersey Flash Flooding: Rescues, Road Closures, Newark Airport Ground Stop

Saturday’s torrential rain turned New Jersey roads into rivers, forcing first responders to pull drivers from submerged cars and leaving thousands without power. The National Weather Service had warned of flash flooding potential heading into the weekend, and by late afternoon that warning became reality as rain fell at rates of 1 to 3 inches per hour.

In Bayonne, firefighters rescued a person from a car trapped in the New Jersey Turnpike roundabout after flash flooding swamped the vehicle. The Bayonne Office of Emergency Management documented the rescue, one of multiple water rescues conducted across the state as roads and vehicles disappeared under rising water.

The storm system also knocked out power to more than 5,000 homes and businesses statewide. Jersey Central Power & Light reported over 4,800 customers affected, according to the utility’s website.

Newark Airport Ground Stop and Travel Disruptions

The severe weather prompted a ground stop at Newark Liberty International Airport, halting departures and delaying arrivals as lightning and heavy rain swept the region. Travelers were advised to check with their airlines for updated flight status.

Radar Knockout and Ongoing Threat

The storms packed significant lightning, which caused at least one fire and knocked out the National Weather Service’s radar system at its Mount Holly office. “KDIX took a direct hit from lightning earlier and will be down until at least tomorrow,” the NWS said in a post on X. The radar outage will hamper forecasters’ ability to track storms in real time until it is restored.

Forecasters warned that another round of storms was expected Saturday night, with a continuing threat of flooding until 2 a.m. A tornado watch that had been in effect was canceled around 8:30 p.m., but the flood risk remained.

Safety Tips for Flash Flooding

With more rain on the way, residents should avoid driving through standing water. Just six inches of moving water can knock a person down, and a foot of water can sweep away a vehicle. If you encounter a flooded road, turn around — don’t drown. Those in low-lying areas should monitor local alerts and be prepared to move to higher ground.

For the latest updates on power outages, check your utility’s outage map. JCP&L customers can report outages and view restoration estimates online. The NWS advises staying tuned to local weather radio or a reliable weather app for real-time warnings.

The combination of intense rainfall, lightning, and saturated ground means the flood threat will persist even after the rain stops. Drivers should expect lingering road closures and debris on highways. The New Jersey Turnpike roundabout in Bayonne remained closed Saturday evening as crews worked to clear water and assist stranded motorists.

This weather event underscores the importance of heeding flash flood warnings. The NWS had flagged the potential for flooding ahead of Saturday, and the rapid onset of heavy rain caught many off guard. With the radar down, forecasters will rely on spotter reports and satellite data to track the next wave of storms.

Residents in flood-prone areas should have an emergency kit ready, including a flashlight, batteries, first aid supplies, and important documents in a waterproof bag. If you live in a basement apartment or a low-lying area, know the quickest route to higher ground.

The storm system is expected to move out by early Sunday, but the flood threat will remain until the ground dries. The NWS will continue to issue updates as conditions evolve, even without the Mount Holly radar.
