Evidence / storm surfaces

How Naples saw the hail — from two instruments

May 17, 2026 · Naples, FL

We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.

NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

The storm in context

Where May 17, 2026 sits in Naples's hail record.

This was Naples's 5th recorded hail day, arriving 27 days after the Apr 20, 2026 storm. By severity it ranks 2nd of the 35 storms we have logged here. Radar put the day's largest stone over Naples at 1.75" — the largest NEXRAD radar signature.

The May 17, 2026 convective day was bigger than Naples: the same system put hail over 894 other tracked cities, 36 of them in Florida. Nearest: Fort Myers (29 miles north, up to 1.25"); Cape Coral (35 miles northwest, up to 1"); Immokalee (36 miles east, up to 1.25").

These maps are stills. In the app this date is one of 35 Naples 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

No reports 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.

For this storm over Naples, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.

High damage potential

What 1.75" hail means for Naples roofs.

Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 30, 2026.
