Alaska Hail Map — Last 30 SPC Reporting Days

While severe thunderstorms are uncommon in the Last Frontier, the Interior and Southcentral regions occasionally experience intense summer convection that produces hail. This Alaska hail map helps residents and contractors track severe weather impacts from Fairbanks to the Mat-Su Valley. This page shows live NOAA/SPC hail reports for Alaska in the last 30 days.

About hail reports in Alaska

Alaska averages less than one severe hail day per year, with most activity occurring during the short summer season from June to August. The state's most notable hail events typically strike the Interior, where warmer summer temperatures can fuel thunderstorm development. Due to the sparse population, damage is usually minimal, but agricultural areas like the Matanuska-Susitna Valley remain vulnerable to crop damage from summer hail.

This Alaska statewide research page connects reported NOAA/SPC hail activity with THOR’s interactive map. Use the map to investigate a place, ZIP code, county, address, or storm area alongside available hail swaths, NEXRAD radar, and Timeline replay.

From hail research to field work

  1. Open the interactive map and review reported hail in the selected area.
  2. Compare the broader storm corridor with radar, hail swaths, and Timeline replay.
  3. Use Market Priority, Impact View, and map layers to focus the next area.
  4. Save the investigation as a property report, lead workflow, alert, or export.

Data and method

THOR uses preliminary NOAA Storm Prediction Center reports as a starting point for local hail research. Reports can be revised or incomplete, so use the interactive map and available radar context to investigate the broader storm picture.

Hail map questions

What is a hail swath map?

A hail swath is a radar-derived estimate of where a hail-producing storm cell traveled. THOR places swaths beside reported hail events, radar, and Timeline replay so you can study the full storm corridor.

Can I check hail history by address?

Yes. THOR searches by address, ZIP code, county, or place and creates Property Storm History reports that stay in My Reports for reopening, sharing, or browser PDF export.

Can roofing teams use THOR for canvassing?

Yes. THOR includes built-in canvassing with map pins, imported leads, statuses, notes, call and drive actions, follow-up dates, Storm Hits, Lead Storm Monitor, and exportable storm data.

How does THOR help prioritize storm damage work?

Market Priority compares the storm events already on the map with household, residential-density, population, and Residential Score context. Impact View, Heat Grid, and Timeline help the team sort the broader storm picture before field follow-up.

Build the next storm workflow

THOR combines nationwide hail research with storm replay, mapping, reports, alerts, canvassing, lead follow-up, and exports in one workspace.
