Introduction: Hurricane Harvey hits Texas, Irma on her way!
According to National Geographic,
It rains at least 2.4 trillion gallons a day. And the wind speed can be over 160 miles an hour.
A hurricane is one of the three names for a rotating tropical storm with winds of at least 74 miles an hour. You call a storm a hurricane if its develops over the atlatic or eastern Pacific ocean, and they are typhoons when they develop in the western Pacific. When a hurricane makes landfall, it often produces a devastating storm surge that can reach 20 feet high and extend nearly 100 miles. Ninety percent of all hurricane deaths result from storm surges.
Hurricanes spin around a low pressure center known as the eye. Sinking air makes this 20 to 30 mile wide area notoriously calm. But the eye is surrounded by a circular eye wall that hosts the storm’s strongest winds and rain.
