Hurricanes and Tornadoes

This table shows the differences between two very strong winds: hurricanes and tornadoes.

A hurricane can be predicted 2-3 days in advance for a wide area and 6-10 hours beforehand, but a tornado can be predicted 20 minutes or less. The minimum wind speed for tornadoes is 40 miles per hour, whereas for hurricanes it is 74 miles per hour. A hurricane has 300 miles of average width of storm and a tornado is 100-600 meters sometimes up to 1.5 km wide. Hurricanes start over warm oceans whereas tornadoes start usually over land. The hurricane is classified on the Saffir-Simpson C1-c5, but the tornado is classified on the Fujita F0-F5. Finally, the average number per year for hurricanes is 100 worldwide.

As you have seen, the tornadoes cause much damage in a few minutes with maximum wind speed 300 miles per hour, but a hurricane's duration will be one week on average.
