Evidence / storm surfaces
How Jupiter saw the hail — from two instruments
Jun 21, 2026 · Jupiter, FL
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
0.5"
Only the radar-estimated size surface resolved for Jun 21, 2026 — this storm produced no NEXRAD point detections over Jupiter, so there is one map to show, not two.
The storm in context
Where Jun 21, 2026 sits in Jupiter's hail record.
This was Jupiter's 3rd recorded hail day, arriving 1 day after the Jun 20, 2026 storm. By severity it ranks 4th of the 4 storms we have logged here. Radar put the day's largest stone over Jupiter at 0.5" — radar-estimated size aloft.
The Jun 21, 2026 convective day was bigger than Jupiter: the same system put hail over 415 other tracked cities, 13 of them in Florida. Nearest: Loxahatchee (17 miles southwest, up to 0.5"); Okeechobee (51 miles northwest, up to 0.75"); Fellsmere (62 miles northwest, up to 0.75").
These maps are stills. In the app this date is one of 4 Jupiter 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
What people on the ground reported
1 report filed with the NWS
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.

Reports came from Caloosa — beyond Jupiter itself.
Below the severe threshold
What 0.5" hail means for Jupiter roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
940 homes × $12,000 avg. claim
Potential roof exposure
$11M
Potential roof exposure — 940 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 940 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
June 2028
Claims from this storm can typically be filed until around June 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

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 24, 2026.
