THOR Storm Mapper
NOAA/SPC SEVERE WEATHER INTELLIGENCE
The Hail Map That Finds Your Leads. Use Population Data to Prioritize the Market. Close More Jobs.
THOR Storm Mapper turns NOAA severe weather data into a real-time intelligence layer for roofing contractors, public adjusters, and homeowners. See every hail event, tornado track, and outbreak the moment it's reported — and have the documentation your clients need to support their storm damage assessments before anyone else is even on the street. Market Priority adds Census population and housing context so your team can compare storm-affected markets by households, residential density, and population.

Live Storm Tracking
Pinpoint every hail event by state, county, and ZIP. Know exactly which neighborhoods took a hit before you make a single call.
Rank the storm events already on the map by households, residential density, population, or a combined residential score. Use the top 50%, 25%, or 10% to narrow the view without changing the underlying weather data.
Live severe weather feeds from the National Weather Service and Storm Prediction Center. No delays, no guesswork.
Visualize tornado paths, wind storm corridors, and multi-event outbreak clusters so you can target the highest-density damage areas.
Get push notifications and email alerts the moment severe weather hits your target area — even when the app is closed. Be the first crew on the street, not the fifth.
Overlay active radar on the impact map to see storms as they move. Predict where damage is happening right now.
Query up to 2 years of storm history. Find markets that were hit repeatedly, build a canvassing strategy around real data, and pull NOAA-verified records to document storm activity long after the storm has passed.
Download storm data as CSV for CoreLogic, SalesRabbit, and any CRM — or as KML for Near Map and Google Earth aerial overlays. Your THOR data, in your workflow, instantly.
Generate a one-click PDF storm history for any address — every hail event, tornado, and wind record within 1 mile, going back to 2014. Reports are saved to your account so you can re-download or share them anytime, without regenerating.
Upload your entire lead base from Spotio, Salesforce, JobNimbus, or any CSV. THOR watches every address around the clock — the moment a qualifying storm hits within your set radius, you get a push notification and email so you're first to the door. Drop lead pins directly on the map, track dispositions, and export storm-hit leads straight to your CRM. Turn a weather event into a closed job.
Import leads from CSV or long-press the map to add a pin. Track dispositions, call or drive from each lead card, open property reports, review Storm Hits, and monitor each lead locally or with the 25-mile Area Monitor.
Scrub through any storm event frame by frame — watch hail swaths build in real time, replay NEXRAD radar from the moment the storm hit, and sync outbreak markers to the exact minute. Present the full storm sequence to a homeowner or adjuster and let the data do the selling.

Built for the Field. Designed to Win Jobs.
Every feature in THOR Storm Mapper is purpose-built for roofing contractors and storm chasers. Here's what you'll see the moment you log in.
Replay Any Storm. Watch the Hail Swaths Lay Down in Real Time.
Hit Timeline and scrub back to any storm event. THOR overlays NEXRAD radar and MRMS-derived hail swaths simultaneously — the colored corridors show exactly where hail fell, how wide the swath was, and how severe it was at each point. This screenshot captures the April 28, 2026 North Texas outbreak: 8 events active at this timestamp, cumulative hail swaths painted across Clay, Archer, and Wichita counties, with a 2.50" EXTREME event at 3 W Bluegrove open in the detail panel. 684 NEXRAD hail signatures. 62 dBZ max reflectivity. This is how you find the damage corridor before you drive it.
18 Tornadoes. 35 Hail Reports. One Map. All Live.
A Great Lakes outbreak captured in real time at 2:55 PM CDT on July 27, 2026. The system header shows 18 tornado reports, 35 hail reports, and 6 wind reports active simultaneously across Wisconsin, Illinois, Indiana, and Kentucky. THOR Storm Mapper was tracking all of it — outbreak polygons drawn, county summaries live, hail markers populating — while the storm was still moving. This is the map open before the last cell clears.
The Most-Hit Counties, Shaded and Ranked. While the Storm Is Still Moving.
Zoomed into the northern Illinois epicenter at 2:56 PM CDT. The colored county polygons show the most-affected counties ranked by storm impact — the deeper the red, the higher the event density and severity. Hail markers dated 07/27 are already visible inside the county boundaries, with event counts logged while the storm was still producing. For a roofing contractor, these county overlays are your canvassing priority list. THOR builds it for you within the hour.
2.00" Hail. 72 mph Wind. All Three Events. Live.
DuPage County Impact Summary captured at 2:56 PM CDT — less than two hours after the first hail report. Max hail: 2.00" (hen egg). Max wind: 72 mph. Three confirmed events across Clarendon Hills, Oakbrook Terrace, and Hanover Park. All sourced from NOAA/SPC storm reports and mPING crowdsourced data. This is the data you bring to the door. Two hours is enough time to route a crew and be knocking before the homeowner has called their insurance company.
EXTREME. Severity 80/100. Hen Egg. On the Map Within the Hour.
The individual SPC event record for the 2.00" hail strike at 1 NW Clarendon Hills, DuPage County, IL — rated EXTREME with a severity score of 80 out of 100. Date: July 27, 2026 at 1:04 PM EDT. Source: mPING crowdsourced report "Hen Egg (2.00 in.)" from NWS Chicago (LOT). Wind verification from HRRR model: 42 mph gust from SW. This data was live on THOR Storm Mapper before most homeowners knew it happened.
See Every Storm-Hit Market at a Glance
The State Impact View paints the entire country with severity-coded county polygons. Deep red means high-density hail and tornado activity — exactly where roofing demand is surging right now. This screenshot shows the 6-month Texas view: 623 events statewide, 58 tornadoes, 227 hail strikes, 338 wind reports, max hail 5.00", max wind 119 mph. Filter by event type, severity, and time range to zero in on the markets worth chasing. Click any state for an instant breakdown. You'll know which markets to chase before your competition is even awake.
Drill Down to the Exact Counties That Need You
Zoom into county level and THOR breaks down every storm event by type, severity, and peak readings. Tarrant County, TX: 7 events, 5 hail strikes up to 3.00" diameter, 2 wind reports peaking at 70 mph. The event list shows exact locations, timestamps, and NWS field reports — including a 3" hailstone measured in Azle and 2.75" reports from Fort Worth and White Settlement. Prioritize your canvassing route before you even leave the truck.
Full Storm Data on Every Single Event
Click any event dot and get the complete SPC record: exact coordinates, hail diameter, severity score, NWS field remarks, and NEXRAD radar signatures. This screenshot shows a CATASTROPHIC 4.50" hail event in Johnson County, TX — scored 155/100 severity, reported by a trained spotter at 4 ESE Godley on April 28, 2026. NEXRAD data shows 108 hail signatures with 8.01" max estimated size. Storm cell structure: 481 readings, max reflectivity 56 dBZ. Wind verification from HRRR/Open-Meteo: 137° gust. This is the data that turns a door knock into a signed contract.

Found a high-severity event? Hit Drive There and your phone opens Google Maps, Apple Maps, or Waze with turn-by-turn directions to the exact storm coordinates. This event — 4 ESE Godley, Johnson County, TX — is a CATASTROPHIC 4.50" hail strike with a peak gust of 33 mph from SE.
