Warn-on-Forecast
Warn-on-Forecast (WoF or WoFS) is an ongoing numerical weather prediction research project being conducted by the National Severe Storms Laboratory (NSSL), a branch of the National Oceanic and Atmospheric Administration, designed to increase the lead time for tornado warnings, severe thunderstorm warnings, and flash flood warnings. WoFS is cloud-based and exclusively targets regions of severe weather to reduce computing expense.
