General information
General Information

  • Hurricanes are devastating powerhouses of wind, rain, and surf.

    • Wind gust can reach 200 mph.

    • Can bring 6 to 12 inches of rainfall.

    • Storm surge can lift the ocean 15-24 feet or more above main sea level, with additional wave action.

    • Tornadoes are likely.

    • Loss of power and communication abilities likely.


Formation of a hurricane

The ingredients for a hurricane  include a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds aloft.

A hurricane is a type of tropical cyclone, which is a generic term for a low pressure system that generally forms in the tropics. The cyclone is accompanied by thunderstorms and, in the Northern Hemisphere, a counterclockwise circulation of winds near the earth's surface.

Formation of a Hurricane


Hurricane formation

The process by which a tropical cyclone forms and subsequently strengthens into a hurricane depends on at least three conditions shown in the figure below

A pre-existing disturbance with thunderstorms.

Warm (at least 80ºF) ocean temperatures to a depth of about 150 feet.

Light upper level winds that do not change much in direction and speed throughout the depth of the atmosphere (low wind shear).

Hurricane Formation


Hurricane anatomy
Hurricane Anatomy subsequently strengthens into a hurricane depends on at least three conditions shown in the figure below

The main parts of a hurricane (shown below) are the rainbands on its outer edges, the eye, and the eyewall. Air spirals in toward the center in a counter-clockwise pattern, and out the top in the opposite direction. In the very center of the storm, air sinks, forming the cloud-free eye.


Hurricane terminology
Hurricane Terminology subsequently strengthens into a hurricane depends on at least three conditions shown in the figure below


Continued hurricane information
Continued Hurricane Information subsequently strengthens into a hurricane depends on at least three conditions shown in the figure below

  • Just as many factors contribute to the birth of a hurricane, there are many reasons why a hurricane begins to decay. Wind shear can tear the hurricane apart. Moving over cooler water or drier areas can lead to weakening as well. Landfall typically shuts off the hurricane's main moisture source, and the surface circulation can be reduced by friction when it passes over land.


Hurricane terminology1
Hurricane: Terminology subsequently strengthens into a hurricane depends on at least three conditions shown in the figure below

  • Tropical Storm Watch:An alert given when a tropical storm ( wind speeds of 39-73 mph) poses a threat to a specific area within 36 hours.

  • Tropical Storm Warning:An alert given when a tropical storm poses a threat to a specific coastal area within 24 hours.

  • Hurricane Watch:An announcement for specific coastal areas that hurricane conditions are possible within 36 hours.

  • Hurricane Warning:A warning that sustained winds of 74 mph or higher associated with a hurricane are expected in a specified coastal area within 24 hours or less.


Saffir simpson hurricane scale
Saffir-Simpson Hurricane Scale subsequently strengthens into a hurricane depends on at least three conditions shown in the figure below

  • The scale below categorizes storms based on sustained wind speeds.

    Cat storm Winds Surge (FT) Example

    Category 1: 74-95 MPH 4-5 Irene 1999

    Category 2: 96-110 MPH 6-8 Floyd 1999

    Category 3: 111-130 MPH 9-12 Alicia 1993

    Category 4: 131-155 MPH 13-19 Hugo 1989

    Category 5: Greater than155 MPH 19+ Andrew 1992

    Surge Indicator Poles, located in each community indicate the maximum expected surge per category. Cat-1 red, Cat -2 orange, Cat-3 yellow,

    Cat-4 green, and Cat-5 purple.


Hurricane storms surge
Hurricane: Storms Surge subsequently strengthens into a hurricane depends on at least three conditions shown in the figure below

  • Storm surge is simply water that is pushed toward the shore by the force of the winds swirling around the storm. This advancing surge combines with the normal tides to create the hurricane storm tide.

  • In addition, wind driven waves are superimposed on the storm tide. This rise in water level can cause severe flooding in coastal areas, particularly when the storm tide coincides with the normal high tides. Because much of the Atlantic coastline is less than 10 feet above mean sea level, the danger from storm tides is tremendous. Waves may reach 20 feet.

  • The level of surge in a particular area is also determined by the slope of the continental shelf. A shallow slope such as the our area, allows a greater surge to inundate coastal communities., although large breaking waves can still present major problems.

What can we expect in 2006 dr william gray
What Can We Expect in 2006 subsequently strengthens into a hurricane depends on at least three conditions shown in the figure below“Dr. William Gray”

  • The 2006 Atlantic hurricane season will be much more active than the average 1950-2000 season. We estimate that 2006 will have about 9 hurricanes (average is 5.9), 17 named storms (average is 9.6).

  • Do not expect as many US landfalls.

  • No El Nino conditions likely, El Nina conditions may exist.

  • We are in a period of heightened hurricane activity for next few years. (Increased Atlantic water temp, little El-Nino activity).

  • Register each year in the spring with Co/Jax EOC, 3 ways.

    • Telephone EOC @ 630-2472

    • On-line at www.coj.net

    • At City Hall ( Pick up a Special Needs form)


After a hurricane what then
After a Hurricane: What Then? winds (115+ MPH), flooding, wave action, and possible tornadoes.

  • Listen to media (radio and TV) for information on re-entry.

  • Realize it will be a slow process. Be patient.

  • Emergency operations will be coordinated with each city through the Beach Complex to Co/Jax EOC.

  • Power will usually be out. And may take days to restore. City Government will be trying to get water, sewer, and power restored.

  • The first priority will be damage assessment and search and rescue operations.

  • Debris will be everywhere. Each city has plans for debris removal.

  • Curfew’s may be necessary.


Re entry process
Re-Entry Process winds (115+ MPH), flooding, wave action, and possible tornadoes.

  • May be days before residents are allowed back due to safety.

    Re-entry Checkpoint:

    • Residents must show a valid re-entry pass.

    • Business managers/owners will be allowed back into the beach area but should have a pass.

    • Law enforcement will coordinate re-entry operations.


Local recovery efforts
Local Recovery Efforts winds (115+ MPH), flooding, wave action, and possible tornadoes.

  • For a major event, theCounty will be dividedinto four sections utilizing the NIMS management system and ICS. The beach cities are in the Beach Complex.

  • Each beach city is responsible for directing their own recovery efforts, however it will be coordinated through the Beach Complex to Co/Jax EOC to utilize County, State and Federal assistance/resources.

  • After a initial damage assessment, search/rescue efforts will be the first priority, while at the same time restoration of power, water, and sewer services.

  • Debris management will also be initiated early on to clear major roadways.

  • Recovery will be a slow process….


Fema what can they do
FEMA: What can they do? winds (115+ MPH), flooding, wave action, and possible tornadoes.
