Wyoming: The Storm-Ready Checklist

Shelter & mitigation money

No dedicated state-run storm-shelter rebate or grant program is listed for Wyoming 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 Wyoming; 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 Wyoming actually faces

• Extreme rainfall and flash flood

  Peak season: Jul

  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.

• Blizzard and ice storm

  Peak season: Oct–Dec

  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.

• 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.
