Evidence / storm surfaces
How Gulfport saw the hail — from two instruments
Aug 21, 2026 · Gulfport, MS
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.
NEXRAD radar signatures Surface resolved

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.

The storm in context
Where Aug 21, 2026 sits in Gulfport's hail record.
This was Gulfport's 5th recorded hail day, arriving 91 days after the May 22, 2026 storm. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Gulfport at 0.75" — radar-estimated size aloft.
The Aug 21, 2026 convective day was bigger than Gulfport: the same system put hail over 659 other tracked cities, 53 of them in Mississippi. Nearest: Saucier (18 miles northwest, up to 0.5"); Waveland (19 miles west, up to 1"); Wiggins (35 miles north, up to 1.25").
These maps are stills. In the app this date is one of 6 Gulfport 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 Gulfport 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 27, 2026.
