2  A hurricane is a big storm that forms over the ocean. Hurricanes form over warm parts of the Atlantic Ocean, and the Pacific Ocean. They form near the equator in the Tropical Zone.  A hurricane is a powerful storm system with a large low pressure center that produces intense winds and heavy rainfall.

3  Warm wet mass of air over the sea that begin to evaporate  Water has to be 79 degrees or warmer  Combined actions of air, water, and heat produce a huge spinning system of clouds rain and wind.

4  Hurricanes are dangerous events. Those of us who have lived through one of these fierce storms are aware of their awesome potential. If you're new to the area, it's easy to fall victim to the "How bad can a storm be?" syndrome.  Here's How:  Select a safe place for the family to weather the storm. This may be a location in your home -- consider a windowless room on the bottom floor. If your home doesn't have a safe area, you should know the locations of at least two emergency shelters near your home. If you have special medical needs and don't think you'll be able to get to the shelter on your own, contact the county in advance to make prior arrangements.  Stock up on food and water. You should have enough non-perishable food and water in your home to last the family for at least a few weeks. If your stock of supplies is old, be sure to refresh it. You might want to purchase new canned goods every few years and rotate the rest through your pantry. Water should be replaced annually.  Prepare other disaster supplies. You'll need to stock up on batteries, flashlights, rope, tarps, plastic bags, bad-weather clothing and other essentials to help you through the aftermath of a bad storm.  Get your home ready. If you have hurricane shutters, make sure that you have all of the parts and have some extra screws/washers handy. If you don't, have a supply of plywood precut to fit your windows. Gather anything loose from your yard and store it in the garage. Watch the news when a storm is approaching and protect your home when advised by local authorities. If you wait until the rain starts, it may be too late.  Develop a family communications plan. You might become separated before or after the storm. It's a good idea to have an out-of-state contact (a relative up north?) to act as the point of contact for all family members in the event of an emergency. Make sure everyone in the family knows who that person is and carries their phone number in their wallet or purse.  Check your insurance coverage. Companies stop writing coverage when a storm is approaching. Ensure that your homeowner's insurance has enough windstorm coverage to rebuild your home in today's market. Also, remember that standard insurance doesn't cover flooding. You'll need special flood insurance from the federal government.  Plan for the family pets. Shelters will not accept pets. If you want to ensure your pets livelihood, you may wish to consider evacuating early to a friend's home that's in a safe area.  Keep your vehicles gassed up to at least half a tank at all times throughout hurricane season. When a storm approaches, lines WILL get long (up to five hours!) and gas stations will run out of gas before the storm hits. You need to have enough gas to safely evacuate if the situation warrants.  What You Need

5  Non-perishable food  Drinking water  Batteries  Medication for all family members  First aid kit  Flashlights  Battery-operated radio  Cash  Toiletries  Clothing

6  Hurricane Effects can create major problems. The maximum effects of a hurricane are usually felt within the right-front quadrant. Here the winds are usually the strongest, storm surge is highest, and the possibility of tornadoes is greatest. It is important to know whether or not your area will be affected by the right-front quadrant. It could mean the difference between maximum hurricane conditions or a glancing blow.  Storm Surge is the fast uprising of sea level that happens when a hurricane approaches the coast. Two factors that cause storm surge are:  Strong winds that push the water toward the coast and Suction created by the storm's low pressure.  High Winds is another effect of hurricanes.  Heavy Rainfall is produced by hurricanes.  Tornadoes are often produced by hurricanes.  Rip tides are another effect of hurricanes.

7  Hurricanes are the most destructive natural weather occurrences on Earth.  Hurricanes have male and female names, but at one point only female names were used.  Most hurricanes rage harmlessly in the sea.  The New England Hurricane of 1938 is reported to have the fastest forward speed for a hurricane at 70 mph. The forward speed for an average hurricane is less than 20 mph.

8  Hurricane season in the Atlantic Ocean runs from June 1 to November 30.  Australians call hurricanes, willy-willies.  Hurricanes can cause billions of dollars worth of property damage every year to man-made fixtures as well as to natural surroundings such as trees and shrubbery. These storms can also change an area's landscape; resulting in hills, roads and trails to wash away.

9  Hurricanes form over a large mass of warm ocean water during the warmer months. Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then that “new” air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean’s heat and water evaporating from the surface.
