Evidence / storm surfaces
How Marrero saw the hail — from two instruments
Aug 21, 2026 · Marrero, LA
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.
Radar-estimated hail size Surface resolved
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.
Max size
0.75"
Only the radar-estimated size surface resolved for Aug 21, 2026 — this storm produced no NEXRAD point detections over Marrero, so there is one map to show, not two.
The storm in context
Where Aug 21, 2026 sits in Marrero's hail record.
This was Marrero's 2nd recorded hail day, arriving 159 days after the Mar 15, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Marrero at 0.75" — radar-estimated size aloft.
The Aug 21, 2026 convective day was bigger than Marrero: the same system put hail over 659 other tracked cities, 77 of them in Louisiana. Nearest: New Orleans (6 miles east, up to 0.5"); Westwego (6 miles west, up to 0.5"); La Place (28 miles northwest, up to 0.5").
These maps are stills. In the app this date is one of 2 Marrero 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.

Near the severe threshold
What 0.75" hail means for Marrero 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.

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 Aug 22, 2026.
