Evidence / storm surfaces
How Grosse Tete saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Sep 21, 2026 — this storm produced no NEXRAD point detections over Grosse Tete, so there is one map to show, not two.
The storm in context
Where Sep 21, 2026 sits in Grosse Tete's hail record.
This was Grosse Tete's 6th recorded hail day, arriving 14 days after the Sep 7, 2026 storm. By severity it ranks 3rd of the 6 storms we have logged here. Radar put the day's largest stone over Grosse Tete at 1" — radar-estimated size aloft.
The Sep 21, 2026 convective day was bigger than Grosse Tete: the same system put hail over 498 other tracked cities, 42 of them in Louisiana. Nearest: Port Allen (9 miles northeast, up to 0.5"); Maringouin (9 miles northwest, up to 0.5"); Baton Rouge (12 miles east, up to 0.5").

Ground reports
What people on the ground reported
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.
Nobody on the ground filed a report over Grosse Tete for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Damage-capable hail signal
What 1" hail means for Grosse Tete roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$108K
Potential roof exposure — 9 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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 $2 on top of the $150 plan.
