Publix Storm Basics - About Hurricanes

There are several types of storms that can form during the Atlantic Hurricane Season (June 1 to Nov. 30); however, hurricanes are the most dangerous. Hurricanes are organized systems of strong thunderstorms that can cover several hundred miles and generate torrential rain and tornadoes. They can also cause storm surges—domes of water that reach 10 to 20 feet above sea level, resulting in deaths and damage to communities. Hurricanes have an area called the eye, which is a calm spot in the middle of the storm. It's important to remember that when the eye passes over your area, only half the storm has passed. The wind will return suddenly from the opposite direction, perhaps with even greater force.

For information regarding evacuation zones and emergency shelters, tune in to your local television and radio stations, call your local Red Cross or your county's Emergency Management Office.

Glossary of Terms

Hurricane: Very strong, pronounced circulation winds of 74 mph or more and gusts up to 200 mph. Hurricanes are classified into five categories based on sustained winds and storm surges. Take a look at the chart below to learn more.

Saffir-Simpson Hurricane Scale
Category	Sustained Winds	Damage	Storm Surge
1	74 - 95 MPH	Minimal: Unanchored mobile homes, vegetation and signs.	4 - 5 ft.
2	96 - 110 MPH	Moderate: All mobile homes, roofs, small crafts, flooding.	6 - 8 ft.
3	111 - 130 MPH	Extensive: Small buildings, low-lying roads cut off.	9 - 12 ft.
4	131 - 155 MPH	Extreme: Roofs destroyed, trees down, roads cut off, mobile homes destroyed. Beach homes flooded.	13 - 18 ft.
5	Greater than 155 MPH	Catastrophic: Most buildings destroyed. Vegetation destroyed. Major roads cut off. Home flooded.	Greater than 18 ft.

Hurricane Watch: Hurricane conditions are a real possibility for the area usually within 36 hours.
Hurricane Warning: Hurricane conditions are expected within 24 hours.
Storm: categorized by its circular wind intensity. Storms circulate clockwise in the southern hemisphere and counterclockwise in the northern.
Tropical Wave: A cluster of clouds and/or thunderstorms with little or no circulation or strong wind.
Tropical Depression: An organized system of clouds and/or thunderstorms with some circulation at surface, highest winds less than 39 mph.
Tropical Storm: An organized system of strong thunderstorms with stronger circulation; highest wind speed 39-73 mph. These storms can quickly accelerate when they reach tropical storm strength and become hurricanes. Storms are named when they reach tropical storm strength.
Tropical Storm Watch: Tropical storm conditions, including winds of 39-73 mph, pose a possible threat to the area within 36 hours.
Tropical Storm Warning: Tropical storm conditions are expected within 24 hours.
