NEXRAD logged 6 hail signatures up to 1"; the estimated-size surface had no signal 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.
Radar signature field 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.
Only the NEXRAD radar-signature surface resolved for Jul 21, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
This was Cape May's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Cape May at 1" — the largest NEXRAD radar signature.
The Jul 21, 2026 convective day was bigger than Cape May: the same system put hail over 703 other tracked cities, 21 of them in New Jersey. Nearest: Milford (28 miles west, up to 1"); Felton (38 miles west, up to 1"); Ocean City (42 miles south, up to 0.75").
These maps are stills. In the app this date is one of 1 Cape May storm date 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.
“Updates previous tornado report from Cape May Point. A waterspout was witnessed going on shore the beach at Cape May point. A narrow path of tree damage was noted along (PHI)”
— NOAA / SPC storm report
“Video was shared on social media of a waterspout moving ashore. Time estimated from radar. (PHI)”
— NOAA / SPC storm report
Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Cape May Point — beyond Cape May itself.
Damage-capable hail signal
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
Potential roof exposure
$22M
Potential roof exposure — 1,840 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 1,840 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
July 2028
Claims from this storm can typically be filed until around July 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 $386 on top of the $150 plan.
