Monitoring of concurrent, co-located tornado and flash flood (TORFF) warnings
Below is the most recent image showing overlapping tornado and flash flood warning polygons thus far in 2017. Warnings are shown if they overlap in space and are valid within 30 minutes of one another, calculated as described in Nielsen et al. (2015, Weather and Forecasting). The images are updated once per day at approximately 1045 UTC. The images are zoomed in on the region where overlapping TORFF warnings are most frequently observed.
Images last updated 1034 UTC Tuesday June 27 2017. (click image to embiggen)
