Emergency Preparedness

TROPICAL STORM AND HURRICANE PREPARATION

Hurricane season begins June 1st of each year and ends November 30th. Florida can be threatened any time during this season.  This information will help you prepare for a hurricane. Please take the time to read this information carefully.

The following are some useful definitions:

• TROPICAL DEPRESSION has winds of less than 39 miles per hour or 34 knots.
• TROPICAL STORM has winds from 39 to 73 miles per hour or 34 to 63 knots.
• TROPICAL STORM “WARNING” once issued, can develop into a hurricane. 
• HURRICANE “WATCH” - a hurricane may threaten the area within 24-36 hours.
• HURRICANE “WARNING” - a hurricane is expected to strike the area within 24 hours or less.
• HURRICANE has winds of greater than 74 miles per hour or 64 knots.
            Category 1 74-95 MPH Minimal
            Category 2 95-110 MPH Moderate
            Category 3 111-130 Major
            Category 4 131-155 Extensive
            Category 5 156 MPH + Catastrophic

WHAT CAN YOU DO TO BE READY IN THE EVENT OF A DISASTER?

Before the Storm
Preparing in advance for hurricane season can determine not only how safely and comfortably you ride out the storm, but also how easily it is to handle the days and weeks after the storm has passed.  Take a look at the information collected below to learn how you can prepare in the days and weeks before a hurricane.

Plan your stay or evacuation:
Stay Home
: However, before you choose this option, make sure you know your elevation. If we experience a storm that may put a significant storm surge in your home, you need to look at the other options. Also, people in manufactured and mobile homes cannot use this option. Mobile homes and manufactured homes are not built to withstand the high winds associated with tropical storms and hurricanes.

Stay With a Friend or Relative Who has a Safe Place: If this is your plan, make arrangements in advance. You need to make sure that where you are going is safe. It defeats the purpose of evacuating if you go to an unsafe place.

Relocate Out of the Area: You may wish to travel out of harm’s way. Be sure to bring a road map and make sure that your car is full of fuel. Stay away from major bodies of water. Make arrangements in advance if you can. If you decide to use this option, go early, traffic will be heavy if you leave at the last minute, and you may not make it to your destination.

Emergency Public Shelters: For more information on Emergency Shelters and a list of available Public Shelters please visit a county Public Library or Publix Super Market near you.

Have a 72-Hour Survival Kit
You should plan to be self-sufficient for at least 72 hours (3 days) during and after a disaster. You should anticipate no water, electrical power, or utilities for that period of time. To ensure the comfort of your family, whether at home or evacuated to another location please download and print the Hurricane Survival Kit (PDF).

Chantal has not produced organized deep convection since early this
morning and is now a remnant low. Recent ASCAT data indicate that
the maximum winds associated with the cyclone remain near 25 kt. The
remnant low is forecast to gradually spin down during the next
couple of days while it slowly makes a small clockwise loop over the
central North Atlantic. By Monday, the low will likely become poorly
defined and dissipate. This is the last NHC advisory on Chantal.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Fri Aug 23 2019

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical
Depression Chantal, located several hundred miles west of the
Azores.

A broad area of low pressure located near the coast of southeastern
Florida continues to produce a large area of showers and
thunderstorms that extend eastward over the northern Bahamas and the
adjacent western Atlantic waters. The system has changed little in
organization since this afternoon, but environmental conditions are
expected to be conducive for gradual development, and a tropical
depression is likely to form over the weekend. The low is forecast
to move generally northwestward near or over southeastern Florida
through tonight, and then move northward to northeastward over the
Atlantic near the east coast of central Florida on Saturday. After
that, the system is expected to move northeastward offshore of the
southeastern United States coast. Regardless of development, locally
heavy rains are possible over the northwestern Bahamas and the
southern and central Florida peninsula through the weekend.
Interests in the northwestern Bahamas, the Florida peninsula, and
the southeast coast of the United States should monitor the progress
of this system. An Air Force Reserve Hurricane Hunter aircraft is
scheduled to investigate the system on Saturday, if necessary.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

Satellite imagery suggests that the circulation associated with an
area of low pressure located about 1100 miles east-southeast of
the Windward Islands has become better defined, but the thunderstorm
activity is limited at this time. Environmental conditions appear
conducive for additional development, and a tropical depression is
likely to form over the weekend or early next week while it moves
generally westward to west-northwestward near 15 mph.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.
