Montana: The Storm-Ready Checklist

Shelter & mitigation money

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

NAIC's June 2025 hurricane-deductible list does not name Montana; 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).

Who to call, before and after

The hazards Montana actually faces

• Blizzard and ice storm

  Peak season: Oct–Jan

  Ice storms cause more prolonged power outages than almost any other winter hazard, because ice loads snap tree limbs and power lines that snow alone would not touch — outages can run days in rural areas. Blizzards add near-zero visibility and windchill to the mix. A household's real blizzard plan is a heat source that doesn't depend on grid power and a stocked pantry that doesn't need refrigeration.

• Hail and derecho

  Peak season: Jun–Jul

  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.

• Riverine and coastal flooding

  Peak season: May

  Riverine and coastal flooding move on a slower clock than flash flooding — hours to days instead of minutes — which is exactly why households underprepare for it. Flood damage is excluded from standard homeowners' policies almost everywhere, so the financial exposure is separate from the physical one, and it is worth checking before, not after, the water rises.
