Stay safe during the storm
Get inside a sturdy structure and stay away from windows — large hail and damaging winds can shatter glass and injure anyone near it. Secure outdoor items. Do not stand under trees or in doorways during high winds.
After the storm: inspect your roof and siding from the ground before climbing anything. Photograph hail damage to shingles, gutters, and windows — documentation matters for insurance. Call a roofer for inspection and a restoration contractor if water got inside.
NWS instruction: For your protection move to an interior room on the lowest floor of a building. If on or near the Great Salt Lake, get away from the water and move indoors or inside a vehicle. Remember, lightning can strike out to 15 miles from the parent thunderstorm. If you can hear thunder, you are close enough to be struck by lightning. Move to safe shelter now! Do not be caught on the water in a thunderstorm.
What this means for restoration and roofing teams
Destructive hail and wind storms translate into a dual damage profile: roof and siding impacts from hail (bruised shingles, dented gutters, broken windows) plus interior water intrusion from wind-driven rain forcing its way behind breached cladding. This is the hail-inspection clock — roofing contractors will be knocking within a day.
The play: restoration teams should coordinate with roofers — tarp first, then dry in. Capture roof condition, hail size reported, and interior leak locations on the first call. Water that enters through hail-punched roofs is clean rainwater initially but escalates as it sits on insulation and drywall.
Field discipline: document roof damage from the ground before anyone climbs. Hail claims live or die on inspection documentation — photograph everything. Keep homeowner payment responsibility clear in writing before work begins.
FEMA & federal assistance
FEMA Helpline 1-800-621-3362 (7 a.m.–10 p.m. local, 7 days). DisasterAssistance.gov, the FEMA app, and fema.gov/drc for recovery centers. Basic eligibility: citizenship or qualified status, identity verification, proof of occupancy or ownership, and unmet needs not covered by insurance. Apply as soon as it is safe to do so.
Looking ahead
When this warning expires at 4:15 PM MDT, the danger does not necessarily end. Flooded creeks can crest after the heaviest rain has passed, downed lines and weakened trees keep roads dangerous, and additional storm rounds may follow. Watch for updated NWS alerts before heading out.
Demand window note: damage-discovery calls typically start within hours and keep coming for days as people find what the storm left behind — wicking drywall, buckling floors, musty odors, and hail marks show up 24–72 hours later. Restoration teams should expect the intake line to stay busy well past the warning’s expiration.
