Hurricane Preparedness Week Continues Through 31 May

High Winds: The intensity of a landfalling hurricane is expressed in terms of categories that relate wind speeds and potential damage. According to the Saffir-Simpson Hurricane Scale, a Category 1 hurricane has lighter winds compared to storms in higher categories. A Category 4 hurricane would have winds between 131 and 155 mph and, on the average, would usually be expected to cause 100 times the damage of the Category 1 storm. Depending on circumstances, less intense storms may still be strong enough to produce damage, particularly in areas that have not prepared in advance.
Tornadoes: Hurricanes can also produce tornadoes that add to the storm's destructive power. Tornadoes are most likely to occur in the right-front quadrant of the hurricane.  However, they are also often found elsewhere embedded in the rainbands, well away from the center of the hurricane. Studies have shown that more than half of the landfalling hurricanes produce at least one tornado. (National Hurricane Center)
