Understanding the spatiality of weather extremes is of concern for a range of applications including emergency management and public health. For this exploratory analysis, a GIS space-time cube will be used to understand the spatial characteristics of tornadoes in the United States. Data from 1994-2018 will be used to identify regional hotspots of tornado variability. Tornado frequency, average power, and EF rating over all tornadoes and for intense tornadoes (>EF2) were examined using an emerging hotspot analysis. Preliminary analysis indicates intensification in both frequency and estimated power of tornadoes in areas of the Southeastern U.S.
