Where the Colorado wind reports came from — September 15, 2026
Every wind report in this storm so far
These are National Weather Service Local Storm Reports — wind an instrument measured or an observer reported, not a radar estimate. Times are MDT. “Measured” means an anemometer reading the NWS flagged as measured (an airport, mesonet or personal weather station); “estimated” means an observer’s estimate; “damage” means the NWS logged what the wind broke, with no speed attached. Speeds are as issued by the NWS.

| 5 NW Mack | 60 mph | 6:10 PM | Public | measured |
By location so far: 5 NW Mack. An NWS wind report names the nearest place the observer or station reported from, not everywhere the wind blew.

Wind reports by city — September 15, 2026
A National Weather Service report names the nearest locality the NWS recognizes, which for the edge of a large city is often a park, a neighborhood or the next town. This section places each report by the city boundary its coordinates fall inside.
No National Weather Service wind report on this date fell inside a Colorado city boundary.
City boundaries are the U.S. Census Bureau TIGER/Line 2025 place limits; Denver neighborhoods use the City and County of Denver’s statistical neighborhood polygons.
Why 60-mph wind matters to an asphalt roof
Wind damages a roof at its edges first. Uplift concentrates along eaves, rakes, ridges and hips and at the corners — the perimeter zones building codes treat as the highest-pressure parts of a roof — and on the slopes facing the wind. The field of the roof is usually the last place to fail.
Standard three-tab asphalt shingles are rated to about 60 mph (ASTM D3161 Class A) and start losing tabs at 45 to 60 mph once the sealant strip has aged; laminated architectural shingles are rated to 80 to 130 mph and start creasing around 60 to 80 mph. The strongest measured gust in this storm this day was 60 mph, past the damage-onset range for three-tab shingles and at the 60 mph rating of ASTM D3161 Class A products; laminated shingles start creasing in this range.
The failure that matters most is invisible from the street: a broken seal strip. A tab lifted by a gust and dropped back in place looks fine, and fails in the next ordinary windy afternoon. Wind damage is progressive, which is why the inspection question is whether the seal was broken, not whether a shingle is missing today.
What to look for if you were under it
- Check from the ground, not the roof. Walking a wind-struck roof is how people get hurt, and a lifted tab does not show from up close anyway.
- Walk the yard and gutters. Shingle tabs, pieces and granule trails on the ground are the most common first sign.
- Look at the edges. Eaves, rakes, ridge and hip caps: lifted, creased, curled or missing tabs, and exposed nail heads.
- Check flashing, vent caps and gutters. Wind bends and displaces metal rather than denting it.
- Photograph what you find with your phone. Phone photos carry a timestamp. Do not edit them.
- Get it inspected. A broken seal strip is invisible from the ground and is the failure that leads to the next one.
Frequently asked questions
Was there damaging wind near Mack on September 15, 2026?
Yes. The National Weather Service has logged 1 wind report so far near Mack on September 15, 2026, the strongest measured at 60 mph at 5 NW Mack.
How strong was the wind on September 15, 2026 in Colorado?
The strongest gust measured in this storm so far was 60 mph at 5 NW Mack (Public). A gust is a point measurement at one instrument; the wind at a specific roof can be higher or lower than that.
Could my roof have wind damage from this?
Possibly, and it would not necessarily show from the street. Wind lifts and creases shingles along eaves, rakes, ridges and hips and on the slopes facing the wind, and its most common damage — a broken seal strip under a tab that dropped back into place — is invisible from the ground and fails progressively in later wind. Roof age and sealant condition change the outcome house by house.
How do I check my roof for wind damage?
From the ground, never by climbing up. Walk the yard and gutters for shingle pieces and granule trails, then look at the roof edges for lifted, creased or missing tabs and exposed nail heads, and at flashing, vent caps and gutters for bent or displaced metal. Photograph anything you find with your phone.
Is wind damage different from hail damage?
Yes. Hail bruises the field of the roof at random points; wind lifts, creases and tears shingles along the edges and on the windward slopes, and it gets worse with each later wind. They are inspected and documented separately, and one storm can do both.
Red Hawk tracks every hail and damaging-wind day across the Front Range. See our other storm reports for the rest of the 2026 season.

Storm figures are National Weather Service Local Storm Reports for Colorado on September 15, 2026 (local time), retrieved from the Iowa Environmental Mesonet archive as of September 23, 2026 and de-duplicated; wind speeds are as issued by the NWS in miles per hour. Warning polygons and wind figures are from the NWS storm-based warning products. Airport gusts are from the IEM ASOS archive, converted from knots. No radar wind estimate is used. Wind-resistance figures are from published shingle standards and impact research. Storm reports indicate where damaging wind occurred; only a physical inspection establishes whether a specific roof was damaged.
