Storm Information

Anatomy of a storm

1. Outflow. The high level clouds moving clockwise out away from the hurricane at heights of over 35,000 feet. These clouds are indicative of air spreading out over the top of the storm, which is essential to its development.

2. Feeder Bands. These are squally bands of showers characterized by strong gusty winds and heavy rains. These bands become more pronounced as the storm intensifies, and are fed by the warm ocean.

3. The Eyewall. A band of clouds, strong winds and heavy rains surrounding the eye of the storm. At the eyewall, there is rapid movement of air toward the center and upward into the cloud.

4. The Eye. What goes up must come down, so with the violent rising air converging toward the storm center at the eye, sinking air develops within. This air dries out, creating the clear, calm eye. Winds are very light here since the focus of convergence and hence strong winds are in the eyewall.

Storm surge

Low pressure in the hurricane can act as a plunger, slightly pulling up the water level. However, the components that contribute to the greatest storm surge affect are the winds blowing to the left side of the storm and the topography of the land as the storm makes land fall. The strongest surge comes ashore just to the right of the eye, where the fierce hurricane winds are blowing toward land. Winds on the left side of the storm might actually cause the water level to run slightly lower than normal. Higher water level allows waves to strike farther inland, causing massive property damage.

Safety tips for tropical storms and hurricanes

Issues to consider before, during and after a hurricane, provided by the National Oceanic and Atmospheric Administration and the National Weather Service

  • Before storm season, hurricane belt residents should trim back dead wood, secure rain gutters and spouts and stock wood to cover windows.
  • When a Hurricane Watch is issued, make sure automobiles are fueled, mobile homes are tied down and supplies are plentiful (batteries, flashlights, bottled water, canned goods, radio, etc.). Windows should be protected.
  • It is up to individuals to decide whether to evacuate as a hurricane approaches. However, it is recommended to leave if local authorities call for an evacuation. Residents near the coast, in flood plains or in mobile homes should plan to leave every time.
  • Those choosing to leave should shut off water at the main and power at the fuse box. Unless arrangements have been made for pets, food and water should be left behind (shelters don't accept animals).
  • Those choosing to ride out the storm should move valuables to upper floors if possible, fill containers or tubs with several days' worth of drinking water, turn refrigerator to coldest setting and stay indoors on the downwind side of house, away from windows.
  • Beware the eye of the storm. Live power lines, rising water and unstable trees and structures continue to be threats despite the temporary calm.
  • Once the all-clear is sounded, be wary of high water or power lines when driving. Report damaged water, sewer and electrical lines. At home, check for gas leaks and spoiled food or water.

    • After the storm

    • Stay turned to local news for important announcements, bulletins, and instructions concerning the storm area, medical aid and other forms of assistance, such as food, water and shelter.
    • Remember that you may not have immediate access to your home. Emergency rescue crews, power crews, and other personnel may be attending to special needs. Roads could be blocked, power lines could be down, and people may be trapped and in need of assistance.
    • Make sure that you have current identification. You may have to pass through identification check points before being allowed access to your home/neighborhood.
    • Avoid driving, as roads may be blocked. Avoid sight-seeing, or entering a storm ravaged area unnecessarily. You could be mistaken for a looter.
    • Avoid downed power lines, even if they look harmless. Avoid metal fences and other metal objects near downed lines.
    • DO NOT use matches in a storm ravaged area, until all gas lines area checked for leaks. (Keep flashlights and plenty of batteries at hand.)
    • Avoid turning the power on at your home if there is flooding present. Have a professional conduct a thorough inspection first.
    • Consider having professionals/licensed contractors inspect your home for damage and help in repairs. This includes electricians, as well as professionals to inspect gas lines, remove uprooted trees, and check plumbing. Remember that downed or damaged trees can contain power lines that can be a hazard.
    • Use a camera or camcorder to record thoroughly any damage done to your home, before any repairs are attempted.
    • In certain areas, the flooding rains that accompany a storm can create pest problems. Be aware of potential pest problems in your area, such as mice, rats, insects or snakes, that may have "come with the storm".
    • Telephone lines will likely be busy in the area; use a phone only for emergencies.
    • Flooding brings with it the risk of waterborne bacterial contaminations. You should assume that the water is not safe and use properly stored water, or boil your tap water.
