Storm chasing, from the forecast to the footage
StormChase.com has been part of storm chasing since 1998. Today we build the tools we use on our own chases, and every one of them runs on official National Weather Service data.
Before the chase
Every storm chase starts with the forecast. StormThreat shows the Storm Prediction Center's tornado, hail and wind outlooks, watches and mesoscale discussions, so you can pick a target area at a glance.
On the chase
Once storms fire, radar is everything. RAVIN shows live NEXRAD reflectivity, velocity and dual-pol data on your Mac, iPhone or Android, with rotation tracks and warnings to help you stay safe while chasing.
Hurricane season
Storm chasing doesn't stop when tornado season ends. HurriMap tracks every tropical storm and hurricane with National Hurricane Center forecasts, models, recon and wind arrival times.
