DATA SOURCE

Reports, tracks, and survey photos come directly from the National Weather Service, NOAA Storm Prediction Center, and the NOAA Damage Assessment Toolkit, the same sources the professionals trust. We've built additional tools and resources on top of their verified data to help others prepare and respond faster.
