How American Fork saw the hail — from two instruments

Sep 22, 2026 · American Fork, UT

Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.

Radar-estimated hail-size map of the storm over American Fork, UT on Sep 22, 2026 — Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Max size 0.75"

Only the radar-estimated size surface resolved for Sep 22, 2026 — this storm produced no NEXRAD point detections over American Fork, so there is one map to show, not two.

The storm in context

Where Sep 22, 2026 sits in American Fork's hail record.

This was American Fork's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over American Fork at 0.75" — radar-estimated size aloft.

The Sep 22, 2026 convective day was bigger than American Fork: the same system put hail over 97 other tracked cities, 5 of them in Utah. Nearest: Sandy (7 miles north, up to 0.75"); Spanish Fork (21 miles south, up to 0.75"); Santaquin (28 miles south, up to 0.75").

These maps are stills. In the app this date is one of 1 American Fork storm date on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.

Near the severe threshold

What 0.75" hail means for American Fork roofs.

A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure

What this storm is worth to a roofer.

14,719 homes × $12,000 avg. claim

Potential roof exposure

$177M

Potential roof exposure — 14,719 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Illustrative jobs: 74 jobs
Illustrative work: ~$1.1M

Close just 0.5% of the 14,719 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.

A storm day here is a convective day — it runs from noon to noon UTC, so late-night hail is grouped with the afternoon storm that spawned it rather than split across two calendar dates. Ground reports are public-domain observations from the NOAA Storm Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 23, 2026.
