• the speed of the winds

• the size of the base

• the way their winds rotate

• the length of the winds

Why do U.S. residents get more advance warning for a hurricane than they do for a tornado?

• Although far more tornadoes than hurricanes hit the U.S. each year, the financial cost of hurricane damage is far greater than the cost of tornado damage.

• Although far more hurricanes than tornadoes hit the U.S. each year, the financial cost of tornado damage is far greater than the cost of hurricane damage.

Why do storm surges occur?

• Excessive rain raises the level of the ocean.

• Wind rotates very quickly to form a cyclone of water.

• Earth shakes and causes the water level of the ocean to rise.

• Ocean water is blown on shore by high winds.

• “. . . always at their strongest in warm seas and with atmospheric conditions that allow the storm to rotate tightly around its eye.”

• “. . . flooding beaches, blowing roofs off houses, toppling buildings, flipping cars, and causing massive trees to tumble to the ground ...”
