Hurricanes & Tornadoes

The table compares two of the most destractive and dangerous of the nature's furies- the hurricanes and tornadoes. Hurricaces can be prepared for but the tornadoes strike with small warning and they can cause a lot of losses. Hurricanes are different from the tornadoes in many respects. They are different in speed of the wind. Where the hurricanes wind speed starts from 74 mph up 200 mph, the tornadoes speed starts from a small speed of 40 mph but it can reach 300 mph. The duration of the hurricanes is up to 1 week average where the tornadoes last for few minutes, sometimes up to a few hours and the wind storm average ranges from 100- 600 meters but some reach up to 1.5 km wide. Hurricanes can be predicted 2-3 days in advance for a wide area and 6-10 hours beforehand for a local area, while the tornadoes can be predicted only 20 minutes or less before they hit. Tornadoes usually start over the land but the hurricanes over warm oceans.
Overall, both are destructive and dangerous but the hurricanes duration is higher than the tornadoes. However, the tornadoes are considered as one of the nature's furies because they destroy whatever comes into their way.
