Where do you get a free hail map?

Enter a street address above, and HailScore generates the map for that exact property — free. The interactive map plots the most recent NOAA Storm Events hail reports within 8 miles of the address — click any dot for its date, reported hail size, and distance from the property — over shaded density layers that include NEXRAD radar hail detections. HailScore's record set holds 42.1M+ NOAA-linked hail records.

Most free hail maps answer at the county or state level — useful for watching a storm on the news, useless for the question that actually matters: did hail reach your street. Because hailstorms are narrow — a swath can hammer one block and skip the next — HailScore anchors the map to the address and shows each report's distance from it, so you can see whether hail was reported near your roof or across town.

The map comes as part of the free report, alongside an exposure score from 0 to 100 and a recent-hail panel from MRMS radar; the dated event-by-event list unlocks with an email step. What a swath looks like on radar — and why the shape matters — is explained here.

Need a hail tracker, not just a history map?

The free map is a storm history — the most recent documented hail reports around the address. For storms happening now, HailScore ingests MRMS MESH — the Maximum Estimated Size of Hail from NOAA's Multi-Radar Multi-Sensor system — every two hours, so yesterday's storm shows up in today's report, months before the NOAA Storm Events ground reports are published.

When a storm day in a Colorado Front Range county reaches a radar-estimated 1.5″ peak, HailScore publishes a preliminary storm page that shades the storm's radar footprint — the area where the radar estimated hail of 1 inch or larger — within hours of the storm passing. The live Colorado hail statistics hub counts this season's hail days as they land and links the season's largest Front Range storm days.

And if what you really want is to stop checking maps altogether: free hail storm alerts email you during hail season (April–September) when MRMS radar estimates hail of 1 inch or larger within about a mile of a saved Colorado address.

The data behind every free hail map

Four public hail datasets — three from NOAA and one from the CoCoRaHS volunteer observer network — each searched around the exact address you enter.

NEXRAD Radar

8.8M+ records

NOAA Doppler radar hail detections from 2015 to present, each with a radar-estimated hail size, from NOAA's Severe Weather Data Inventory and refreshed weekly.

MRMS Live

32.9M+ records

MESH — Maximum Estimated Size of Hail — ingested every two hours, so yesterday's storm shows up today.

Storm Events DB

308K+ records

Storm reports, nearly all of them hail, from spotters, emergency managers and law enforcement — quality-controlled and published by NOAA months after the storm.

CoCoRaHS

25K+ records

Volunteer observer measurements from the Community Collaborative Rain, Hail and Snow Network.

Frequently asked questions

Where can I find a free hail map?+

Enter any US street address in the search box above and HailScore generates one. It plots the most recent NOAA Storm Events hail reports within 8 miles of the address as dots — click one for its date, reported hail size and distance from the property — over shaded density layers that include NEXRAD radar hail detections. The map, the exposure score and a recent-hail panel from MRMS radar are free, with no signup and no credit card; the dated event-by-event list unlocks with an email step. HailScore's record set holds 42.1M+ NOAA-linked hail records.

Is there a free hail map by ZIP code?+

Yes — enter any street address inside the ZIP and the map covers the area around it. HailScore searches an 8-mile radius from that exact address, so the reports you see are anchored to a real point instead of a postal boundary; an address near the middle of the ZIP gives the most even view of it. If you're starting from a ZIP code rather than an address, the free hail reports by ZIP code page walks through it.

Is there a free hail tracker for storms happening now?+

Not a live radar loop — HailScore records hail after it falls. It ingests MRMS MESH (Maximum Estimated Size of Hail) every two hours, so a storm that hit yesterday appears in today's report; MESH is defined at https://www.myhailscore.com/mesh. When a storm day in a Colorado Front Range county reaches a radar-estimated 1.5″ peak, HailScore publishes a preliminary storm page that shades the storm's radar footprint within hours. For Colorado addresses, free storm alerts email you during hail season (April–September) when MRMS radar estimates hail of 1 inch or larger within about a mile of a saved address. MESH is tuned so that roughly 75% of measured hail comes in at or below the radar estimate; read a size as a class (within about one tier), not as a measurement.

What does the hail map actually show?+

Each dot is one NOAA Storm Events hail report — a ground report compiled by the National Weather Service — plotted at its recorded coordinates around the address you entered; click it for the date, reported hail size and distance. The map shows the most recent reports, not an unlimited archive. The shading is drawn as density rather than as individual pins: a glow around those same reports at neighborhood zoom, and a layer of NEXRAD radar hail detections. Above the map, a recent-hail panel shows MRMS radar hail near the address and is stamped with the time that data was current as of. The dated event-by-event list, labelled with the NOAA Storm Events Database as its source, unlocks with an email step.

Does a hail map show roof damage?+

No. A hail map shows where and when hail was recorded near a property. These are records of hail exposure, not of damage: size is a class, not a measurement, and a hail record near a property is not a finding that the property was damaged. Whether hail cracked or de-granulated anything on a specific roof cannot be seen from radar or satellite — only a physical inspection by a licensed contractor can establish that. Use the map to decide whether an inspection is worth scheduling, and to match event dates against problems you've noticed.

Why does HailScore ask for an address instead of showing one big national map?+

Because the useful question is never 'where did it hail in America' — it's 'did hail reach MY street.' A national map compresses the whole country's hail record into shading you can't act on. HailScore geocodes the exact address and runs a geographic radius query against the NOAA-linked record set, so every dot on the map carries its distance from your property. You still see the recent storm history of the surrounding area — it's just anchored to the point you actually care about.
