Louisiana Hail Map — Last 30 SPC Reporting Days

Louisiana experiences frequent severe weather and destructive hail events driven by Gulf moisture and cold front collisions. This page provides live NOAA and SPC hail reports updated every 6 hours, helping residents and contractors track recent severe storms, storm cell tracks, and hail size distributions.

About hail reports in Louisiana

Louisiana is subject to severe spring and summer thunderstorms that frequently drop golf-ball to baseball-sized hail, particularly across northern and central parishes. Notable events include severe supercells affecting Shreveport, Monroe, and Alexandria with destructive large hail causing extensive roof and automotive damage. The state averages multiple severe hail days annually as maritime tropical air masses interact with vigorous upper-level disturbances.

This Louisiana 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.
