Severe Thunderstorm Warning: Holly–Granada Area Until 7:15 PM MDT

The National Weather Service in Pueblo has issued a Severe Thunderstorm Warning with a considerable damage threat tag for northeastern Prowers County and southeastern Kiowa County in southeastern Colorado — including the communities of Holly, Granada, Hartman, and Bristol — until 7:15 PM MDT. At 6:29 PM MDT, Doppler radar tracked a severe thunderstorm 11 miles northwest of Bristol, 17 miles northeast of Lamar, moving south at 20 mph, packing tennis-ball-size hail and 70 mph wind gusts. Hail this size damages roofs, siding, windows, and vehicles on impact — the NWS expects exactly that from this storm.

This is a live snapshot as of about 6:35 PM MDT. Conditions change fast — always verify with the National Weather Service for your specific county or ZIP code.

Stay safe through this storm

• Hail this large can injure anyone caught outdoors — get inside a sturdy building now, and keep pets indoors.
• Move to an interior room on the lowest floor of a building. Remain alert for a possible tornado: if you spot a tornado, go at once into the basement or a small central room in a sturdy structure.
• Stay away from windows — hail and wind-driven debris shatter glass. Move vehicles under cover if you can do so safely; otherwise leave them.
• After the storm, photograph any damage before cleanup begins. Documentation matters for insurance, and hail bruising on shingles is easy to miss once the ground dries.
• Watch for downed power lines in tree-damaged areas and never touch them — call the utility instead.

What this means for restoration teams

A considerable-tagged hailstorm with tennis-ball hail is a roof-damage event first and a water-intrusion event second. Here’s how the next 48 hours typically play out for contractors in the Holly–Granada corridor.

Damage categories to expect:

• Roof and envelope: 2.5-inch hail bruises asphalt shingles, dents metal roofing, cracks siding, and breaks windows and skylights. Hail damage can be hard to spot from the ground — the NWS expects damage to roofs, siding, windows, and vehicles, so close inspection and thorough documentation are what matter.
• Vehicle and outbuilding damage: Mobile homes, sheds, and outbuildings take wind damage first; expect calls about torn skirting, displaced roofing, and hail-pocked siding.
• Delayed water intrusion: Cracked shingles and compromised flashing don’t leak tonight — they leak at the next rain. Claims and callbacks trail the storm by days to weeks, which is why the follow-up call matters as much as the storm-night response.
• Tree and debris: Considerable tree damage means fallen limbs on roofs, punctured decking, and blocked access for inspection crews.

The play tonight:

• Staff the phones through the evening — homeowners typically discover damage at first light, so be ready for inspection requests in the morning.
• Offer free storm inspections with photo documentation: granule loss at gutters, bruising on shingles, dent patterns on vents and gutters (soft metals tell the hail story an adjuster needs).
• Capture address, roof type and age, and visible damage zones on the first call — adjusters ask for all of it.
• Field discipline: photograph everything before mitigation, keep temporary-cover work documented separately from permanent repair estimates, and keep the homeowner’s payment responsibility clear in writing before work starts.

Timing note: Inspections and adjuster scopes typically trail the storm by days to weeks — thorough documentation at the first inspection is what repair scopes are built on.

FEMA & federal assistance

FEMA Helpline: 1-800-621-3362 (7 a.m.–10 p.m. local, 7 days a week). You can also apply at DisasterAssistance.gov, through the FEMA app, or find a recovery center at fema.gov/drc.

Basic eligibility: U.S. citizenship or qualified status, identity verification, proof of occupancy or ownership, and unmet needs not covered by insurance. Apply as soon as it’s safe — and keep in mind that hail damage is almost always an insurance claim first; FEMA assistance applies to uninsured or underinsured losses and unmet needs.

Looking ahead

The warning runs until 7:15 PM MDT as the storm moves south at 20 mph. When it expires, the hail threat ends with the cell — but the inspection window is just opening. Additional rounds of storms are possible in the region this evening, so contractors should watch radar through the night before scheduling Monday-morning inspection routes. The next NWS update lands at or before expiry if the threat continues.

For restoration teams, the real work starts at sunrise: roof inspections, photo-documented damage assessments, and getting on homeowners’ schedules early.
