Community Vulnerability Profiler

Search a US city or click the map to see a neighborhood-level view of who and what is most exposed to tornado impact.

TornadoScope combines housing vulnerability (construction age, manufactured housing, building types, shelter access) with population sensitivity (elderly, children, group quarters, language barriers) into a relative vulnerability screen.

How to use this

Use TornadoScope to identify neighborhoods that may need earlier attention when a tornado threat is active.

What it does not do

This is not a tornado forecast, damage prediction model, or substitute for local operational judgment. It is a relative vulnerability screen built from Census housing and population data.
