New Jersey: The Storm-Ready Checklist

Shelter & mitigation money

No dedicated state-run storm-shelter rebate or grant program is listed for New Jersey in the mitigation data reviewed for this page. Check with the state emergency management agency below for anything new.

NAIC lists New Jersey among the 19 states plus DC with a separate hurricane or named-storm deductible in homeowner policies as of June 2025 (content.naic.org/insurance-topics/hurricane-deductibles).

Who to call, before and after

The hazards New Jersey actually faces

• Extreme rainfall and flash flood

  Peak season: Sep

  Flash flooding is the deadliest hazard tied to rainfall, and most of those deaths are people driving into water they underestimated — six inches of moving water can stall a car, twelve can float one. Rainfall intensity, not just total inches, is what overwhelms storm drains and low-lying roads in a window of an hour or less.

• Hail and derecho

  Peak season: Jun–Oct

  Hail and derecho winds arrive inside the same thunderstorm complex, often with less lead time than a tornado warning because the threat is the whole storm line, not a single funnel. Large hail totals more property-damage claims nationally than any other severe-storm hazard, and derecho wind gusts can match hurricane-force winds hundreds of miles from open water. Vehicles under cover and loose yard items secured before the line arrives are the cheap fix.

• Lightning

  Peak season: Jun–Aug

  Lightning is the most common severe-weather hazard by frequency, and most strikes happen well before or after the heaviest rain — the 30-30 rule (shelter if under 30 seconds between flash and bang, wait 30 minutes after the last one) still holds. It is also the hazard households prepare for least, because it rarely triggers a county-level warning of its own.
