Tornadoes
Select a tornado from the table to zoom into the track and view more information. The default table view is limited to 8 tracks, but can be scrolled by a mouse wheel or dynamically expanded. Additionally, the table can fill the entire window by clicking the small circular expanding arrow icon at the very top right of the table and returned to its original size by clicking the button again. The side information panel that opens over the map can be closed using the "X" on the upper right corner of the pop-up. Zoom into the map and click damage points to see detailed information and pictures from the surveys.
The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:

EF1 Moderate 86-110 mph |
EF2 Significant 111-135 mph |
EF3 Severe 136-165 mph |
EF4 Extreme 166-200 mph |
EF5 Catastrophic 200+ mph |
