NAIC's June 2025 hurricane-deductible list does not name Illinois; NAIC notes other states may still allow insurers to include one, and a separate wind/hail deductible can appear in any state's policy regardless (content.naic.org/insurance-topics/hurricane-deductibles).

Hazards

The hazards Illinois actually faces

• Extreme cold

  Peak season: Jan–Feb. Extreme cold turns ordinary failures (a stalled car, a lost power connection, a wet coat) into emergencies far faster than people expect, and hypothermia risk starts well above freezing once wind and moisture are factored in. Frozen and burst pipes are the most common property-damage claim tied to cold snaps, and they are largely preventable with basic insulation and a known shutoff valve.

• Extreme heat

  Peak season: Jul. Extreme heat kills more people in an average US year than any other weather hazard, and most of those deaths are preventable: the risk concentrates in the first heat wave of the season, before bodies acclimate, and in households without reliable cooling. Checking on elderly or isolated neighbors during a heat advisory does more than any single piece of equipment.

• Tornado

  Peak season: Nov–Feb. Tornadoes form fast, and even a well-run warning system only buys minutes. The National Weather Service's after-action reports on the deadliest US tornadoes trace back to the same pattern: people heard a warning, stepped outside to look for the funnel, and lost the time a sheltered household would have had. A named safe room (the lowest floor, smallest interior room, most walls between you and outside) and a rehearsed trigger point close most of that gap.
