FAQ
Each line represents a single tornado. Only tornadoes that traveled more than 20 miles are drawn on the map (~2000!).
Line length and width are proportional to the tornado's; opacity and color to wind speed.
NOAA only collects start and end locations - tornadoes do not actually travel in perfectly straight lines.
