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.
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.
The storm in context
This was North Haverhill'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 North Haverhill at 1.75" — the largest NEXRAD radar signature.
The Apr 16, 2026 convective day was bigger than North Haverhill: the same system put hail over 151 other tracked cities, 7 of them in New Hampshire. Nearest: Newbury (5 miles west, up to 1.75"); Woodsville (7 miles east, up to 1.75"); Topsham (10 miles west, up to 1.75").
These maps are stills. In the app this date is one of 1 North Haverhill 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.
“Delayed report. Social media photos of hail up to 1.25 inches in diameter in Center Haverhill near intersection of Route 116 and French Pond Rd. Wind damage reports str (GYX)”
— NOAA / SPC storm report
“Hail up to 1.5 inches in North Haverhill on Route 10. Spotter ID: HL590. (GYX)”
— 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 Newbury and Woodsville — beyond North Haverhill itself.
High damage potential
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.

Roofing exposure
Potential roof exposure
$14M
Potential roof exposure — 1,170 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 1,170 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
April 2028
Claims from this storm can typically be filed until around April 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 $246 on top of the $150 plan.
