All of New Jersey is under a rare "enhanced" tornado risk today, the National Weather Service in Mount Holly warned, with scattered afternoon and evening storms that could bring damaging wind, hail, rapid flooding and the possibility of stronger-than-usual tornadoes.
What to expect for residents
Forecasters said storms will become more intense through the afternoon and may continue into the evening, possibly as late as midnight. Most cells are expected to be brief but capable of producing very heavy rain — rates of 2–3 inches per hour — which raises the chance of flash flooding in vulnerable areas.
Amanda Lee, a meteorologist at the Mount Holly NWS office, emphasized the unusual nature of the advisory for New Jersey. "Typically, when we see tornadoes in New Jersey, they're generally on the weaker side, 0 to F1 strength," she said, adding that the day's setup raises the potential for stronger twisters with a reasonable maximum of F2 intensity.
"The potential maximum today, reasonably, could be F2," Amanda Lee, NWS Mount Holly, said.
How likely and how strong
Lee placed the odds that a tornado will touch down within 25 miles of any given location in the state at roughly 5% to 9% during the threat period. While most New Jersey tornadoes are weak, an F2 would bring significantly greater destructive power.
| EF Rating | Wind speeds (mph) | Typical damage |
|---|---|---|
| F1 | 73–112 | Peel roofs, move autos, damage mobile homes |
| F2 | 113–157 | Considerable damage: snapped large trees, demolished mobile homes |
Preparedness steps
The NWS recommends residents be ready to act quickly if warnings are issued. Practical steps include finding a safe shelter location, keeping a battery-powered radio or a charged phone for alerts, and avoiding flash-flood-prone areas. The NWS website lists additional tornado safety precautions.
- Monitor local forecasts and watches — conditions may change rapidly.
- Prepare a safe room or interior lowest-level space away from windows.
- Have emergency supplies and a way to receive severe-weather warnings.
- Avoid driving through flooded roads; turn around, don’t drown.
New Jersey typically sees many "marginal" and "slight" tornado outlooks each year, but "enhanced" level advisories are issued only once or twice annually on average. Higher levels — "moderate" and "high" — are rarer still in the state, with "high" risks generally limited to the central U.S.
Residents should treat the alert seriously and be prepared to move to shelter if a tornado warning is issued for their area. Local emergency management offices and municipal channels will provide updates tailored to specific counties and towns as the situation evolves.
News Block will monitor updates from the National Weather Service and local agencies and will provide new information as it becomes available.
