The estimated-size surface reached 0.5" aloft; NEXRAD logged no point detections over Deerfield Beach that day. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
Evidence / storm surfaces
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.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Sep 18, 2026 — this storm produced no NEXRAD point detections over Deerfield Beach, so there is one map to show, not two.
The storm in context
This was Deerfield Beach's 3rd recorded hail day, arriving 54 days after the Jul 26, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Deerfield Beach at 0.5" — radar-estimated size aloft.
The Sep 18, 2026 convective day was bigger than Deerfield Beach: the same system put hail over 157 other tracked cities, 7 of them in Florida. Nearest: Naples (98 miles west, up to 0.5"); Bonita Springs (105 miles west, up to 0.5"); Punta Gorda (116 miles northwest, up to 0.5").
These maps are stills. In the app this date is one of 3 Deerfield Beach 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
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.

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Lighthouse Point — beyond Deerfield Beach itself.
Below the severe threshold
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
Potential roof exposure
$12M
Potential roof exposure — 1,024 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 1,024 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
September 2028
Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $215 on top of the $150 plan.
