A survey finds entire stories of well-built houses destroyed and heavy cars lifted and thrown. Using the Enhanced Fujita table in the figure, what rating fits this damage?
A tornado peels roof covering from a house, damages gutters, breaks tree branches, and pushes over shallow-rooted trees. Which EF rating matches the table?
Damage includes roofs severely stripped, exterior doors lost, windows broken, and mobile homes overturned. Using the figure, which EF rating fits best?
A damage team sees roofs torn off well-built houses, frame homes shifted on foundations, and mobile homes completely destroyed. Which EF rating should they assign?
Several well-built frame houses are completely leveled, but the debris is not swept clean from the foundations. Which rating is indicated by the table?

On the map, selected states show average annual tornado counts. Which selected state has the most tornadoes?
A map compares tornadoes per equal-size land area for Florida, Kansas, Maryland, and Texas. Which selected state has the highest tornado density?
The map shades Louisiana, Mississippi, Alabama, and Georgia darker than Plains states for winter tornado risk. What does that seasonal pattern show?
The map contrasts spring tornado risk in Texas and Oklahoma with summer risk in Nebraska, the Dakotas, and Minnesota. In what direction does the main risk shift by summer?
