A storm briefing should make the evidence easier to understand, not force your team to assemble screenshots, tabs, and notes after the fact. Outbreak Storm Reports bring the selected storm picture together in one saved, printable record.
When you are reviewing a large storm corridor, the question is often simple: what happened here, where was the strongest evidence, and what should the team look at next? THOR's new Outbreak Storm Reports are built around that decision. Select an outbreak, create the report, and THOR preserves that reviewed event set in My Reports so you can reopen or print it later.
One storm footprint map, with a key you can read
The report's main map keeps the saved storm evidence on one terrain view. Colored polygons show THOR's radar-derived hail swaths, while pins show the saved NOAA/SPC event reports. A compact key identifies the reported-event pins and the hail-size thresholds that appear in the selected storm footprint.
We deliberately removed the old outbreak-outline treatment from the report. The goal is a more useful scene: the swaths and reported events that help your team understand the storm, without a second boundary competing for attention.
Historical radar that stays with the area you are reviewing
Storm Reports also include one or two source-rendered historical radar maps from the Iowa Environmental Mesonet. Instead of a tiny national composite, each map is bounded around the saved outbreak footprint and includes county lines, interstates, place labels, and an in-image reflectivity scale. The report shows the UTC reference time and source label for every frame.
That makes radar useful as geographic storm context. It does not turn radar into a damage finding, and it does not replace the actual event-level reporting behind the report.
| What the report preserves | Why it matters in the field |
|---|---|
| Saved outbreak selection | Return to the exact storm event set you reviewed instead of rebuilding it from a changing live map. |
| Hail-and-event footprint map | See radar-derived hail swaths and saved NOAA/SPC event markers together, with a readable key. |
| Localized radar context | Review the storm near the affected area with geographic reference layers and a reflectivity legend. |
| Event inventory and source notes | Keep reported dates, times, locations, magnitudes, and source/use context in the same printable record. |
Saved in My Reports, ready when the conversation moves
Outbreak Storm Reports are user-owned and saved in My Reports. That means the report is available when you need to brief a crew, review an affected corridor, or bring a dated storm record into a homeowner or team conversation. Open it again to read the saved evidence set or use the browser's normal print flow for a branded PDF.
THOR keeps the purpose clear: the report is for storm research and field planning. It does not prove property damage, guarantee a lead, replace an inspection, or establish insurance coverage.
Build the next storm briefing from the map
Open a selected outbreak in THOR, choose Create Storm Report, and find the completed record in My Reports. From there, your team has one stable place to review the footprint, the radar context, and the reported events behind the storm.
THOR Storm Mapper includes a 14-day free trial with no credit card required. Start a trial and build your next storm briefing from the map.
