What is a hurricane？
You may already know that hurricanes are storms that can cause devastating（毁灭性的） waves，wind，and rain．They happen during"Hurricane Season，"which is from June 1st until November 30th in the Atlantic Ocean and from May 15th until November 30th in the Pacific Ocean．
Categories（类别）of Hurricanes
There are five categories of hurricanes，which are based on wind speeds．The categories help people know how much damage（危害） a hurricane may cause because the greater the wind speed，the more dangerous the storm．For example，a Category 5hurricane has winds over 155miles per hour，which are strong enough to destroy the buildings along the shorelines completely．
Hurricane Dangers
When a hurricane happens together with heavy rainfall，there can be a devastating flood．The centre of a hurricane is called the eye．While most of a hurricane has dangerously strong winds，the eye is actually（事实上） a calm area in the storm．When the eye of a hurricane passes over land，people might think that it's over，but before long the wind and rain increase again as the second part of the hurricane moves through．
Hurricane Safety Tips
There is no way to stop a hurricane or make it change direction，so if you ever find yourself in the path of a hurricane，be sure to remember the following safety tips．
•Be sure you have a radio，batteries，fresh dinking water，and enough food．
•Tell neighbours，friends，and family members your emergency plans．Tell them where you'll go if you need to leave your home．
•If you live near the ocean，leave your home and travel to a safe place．You could stay with a friend or a family member，in a hotel/motel，or in an emergency shelter area．
•Stay inside during the storm．You could be seriously injured（受伤） if you go outside．
