StormThreat: Severe Storm Maps

StormThreat puts the Storm Prediction Center’s core severe-weather products on a clean, fast, map-first screen so you can see the risk area, watch boxes, and what’s being reported — without digging through multiple pages.

If you make decisions based on SPC guidance, this is the “open the map and know” app.

What you can view in StormThreat:

SPC Convective Outlooks (Day 1 / Day 2 / Day 3 / Day 4–8)

Mesoscale Discussions (MCDs)

Active watch polygons (tornado and severe thunderstorm)

Local Storm Reports (LSRs)

Historical archive browsing (availability may vary by build/release)

Built for real-world use:

Big, readable layers and simple controls

Designed to check quickly during busy weather days

Works as a companion to official SPC products and wording
