The estimated-size surface reached 0.75" aloft; NEXRAD logged no point detections over Hammond that day. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.

Evidence / storm surfaces
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Sep 7, 2026 — this storm produced no NEXRAD point detections over Hammond, so there is one map to show, not two.
The storm in context
This was Hammond's 8th recorded hail day, arriving 15 days after the Aug 23, 2026 storm. By severity it ranks 2nd of the 8 storms we have logged here. Radar put the day's largest stone over Hammond at 0.75" — radar-estimated size aloft.
The Sep 7, 2026 convective day was bigger than Hammond: the same system put hail over 163 other tracked cities, 39 of them in Louisiana. Nearest: Ponchatoula (7 miles south, up to 0.75"); Loranger (9 miles northeast, up to 0.75"); Holden (18 miles northwest, up to 0.5").
These maps are stills. In the app this date is one of 8 Hammond storm dates 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.
Ground reports
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
“Tornado began in a parking lot on West Thomas Street and traveled south-southwest for around 3 quarters of a mile. Damage was mostly to trees however... minor structura (LIX)”

Near the severe threshold
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
Potential roof exposure
$217M
Potential roof exposure — 18,118 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 18,118 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.
Claim window
September 2028
Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $3,805 on top of the $150 plan.
