Hurricanes and Tornadoes

This table shows the differences between two very strong winds: hurricanes and tornadoes.
The minimum wind speed of hurricanes is 74 mph but of tornadoes is 40 mph. However the maximum wind speed for hurricanes is from 155-200 mph but for tornadoes is higher. Hurricanes’ classification scale is the Saffir-Simpsoncl-C5 where as the tornadoes scale is the Fujita F0 –F5.However the hurricanes’ duration is 1 week on average but the tornadoes mostly only last a few minutes. The average width for hurricanes is 300 miles but tornadoes start from 100-600 meters, with some up to 1.5km wide. The hurricanes can be predicted 2-3 days for a wide area; whereas tornadoes can’t be predicted far in advance. Tornadoes start usually over land but hurricanes start over warm oceans.
All in all, I think that the tornadoes are much more dangerous than hurricanes and the maximum wind also for the tornadoes is higher than for hurricanes.
