Two ways to read the storm

How Naples 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.

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 May 18, 2026 sits in Naples's hail record

This was Naples's 6th recorded hail day, arriving 1 day after the May 17, 2026 storm. By severity it ranks 5th of the 26 storms we have logged here. Radar put the day's largest stone over Naples at 1.5" — the largest NEXRAD radar signature.

The May 18, 2026 convective day was bigger than Naples: the same system put hail over 726 other tracked cities, 6 of them in Florida. Nearest: Cape Coral (24 miles northwest, up to 1"); Marco Island (28 miles south, up to 1.5"); Immokalee (34 miles east, up to 0.75").

These maps are stills from Naples's May 18, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

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.

No ground reports were filed with the National Weather Service for this storm over Naples. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Widespread claimable damage

What 1.5" hail means for Naples roofs

At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.

What this storm is worth to a roofer

$1.6M

Potential roof exposure — 133 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Illustrative jobs

Illustrative work

~$15K

Close just 0.5% of the 133 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.

Claims from this storm can typically be filed until around May 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
