2006 Hurricane Evacuation Contraflow Routes (PDF, 457KB)


Hurricanes cause massive damage and loss of life. From the 1900 storm that devastated Galveston Island, killing more than 6,000 people, to Hurricane Alicia in 1983, Texas has weathered 10 of the 30 worst hurricanes in United States history. Since then, thousands of new residents have moved into high-risk areas with little or no experience of preparing for or surviving storms of such magnitude. Many other Texans have acquired a false sense of security believing that, "It won't happen to me." Don't be a casualty of our next hurricane. Plan ahead...the following information will help.

Disaster Supplies








Saffir-Simpson Hurricane Scale

A 1-5 rating based on the hurricane's present intensity.  This is used to give an estimate of the potential property damage and flooding expected along the coast from a hurricane landfall.  Wind speed is the determining factor in the scale, as storm surge values are highly dependent on the slope of the continental shelf in the landfall region.

Tropical Cyclone

A warm-core cyclone or storm not associated with a cold front.  A tropical cyclone will have organized deep convection or thunderstorm activity and a closed surface wind circulation about a well-defined center.


Tropical Depression

A type of tropical cyclone with maximum sustained winds of less than 39 miles per hour.


Tropical Storm

A type of tropical cyclone with maximum sustained winds of between 39 mile per hour and 73 miles per hour.



The most extreme form of tropical cyclone in which maximum sustained winds are greater than 73 miles per hour.


Tropical Storm Watch

An announcement for specific coastal areas that tropical storm conditions are possible within 36 hours.


Tropical Storm Warning

A warning that sustained winds within the range of 39 to 73 miles per hour associated with a tropical cyclone are expected in a specific coastal area within 24 hours.


Hurricane Watch

An announcement for specific coastal areas that hurricane conditions are possible within 24 hours.


Hurricane Warning

A warning that sustained winds of 74 miles per hour or higher associated with a hurricane are expected in a specific coastal area within 24 hours.  A hurricane warning can remain in effect when dangerously high water or a combination of dangerously high water and exceptionally high waves continue, even though winds may be less than hurricane force.



An organized band or of thunderstorm clouds that surround the eye or relatively calm storm center.


Storm Surge

The abnormal rise in sea level caused by the effects of wind from a hurricane or other intense storm.  Storm surge is not a sweeping tidal wave.


Storm Tide

If the storm surge arrives at the same time as high tide, the water height will be even greater.  The storm tide is the combination of the storm surge and the normal tide.



Flooding may result from either rainfall or storm surge inundation.  A large amount of rainfall within a short period of time causes the fallen water to collect outside the normal boundaries of ditches, rivers, streams, lakes, and flood canals.  Depending on natural and man-made factors, the following associated hazards are possible:

  • Drowning

  • Electrocution from fallen live wires

  • Sickness from drinking contaminated water

  • Property damage or loss

  • Possible attacks from pets and wild animals (snakes, dogs, alligators, rats, etc.) escaping the flood waters

Am I at risk from a hurricane?

Look at the color-coded maps below to find out how you would be affected by a hurricane. It shows the areas at risk from winds, rain, and storm surge associated with hurricanes. There are five of these risk areas, each shown in a different color and each corresponding to one of the five categories of hurricanes on the Saffir-Simpson Scale. The stronger the storm, the greater the inland impact will be and the more risk areas affected.  Notice Sweeny is in Risk Area 5 the lowest risk area.

How will I know when to evacuate?

Your local officials will tell you. During a "hurricane watch," listen to your radio or television constantly. Emergency officials can interrupt routine broadcasts to give special weather updates, warning messages, and evacuation information. Tune to KTRK, 740 AM; KPRC, 950 AM or KLOL, 101.1 FM for this information. For 24-hour weather broadcasts from the National Weather Service, tune to NOAA Weather Radio on the high-band FM frequency 162.55 megahertz (MHz) that broadcasts from Galveston, 162.40 MHz that broadcasts from Houston, or 162.425 MHz that broadcasts from Bay City.  Information will also be posted on our home page.

What can I do to prepare for a storm?

While there are no sure ways to predict when and where a hurricane will come ashore in Texas, both cities and counties have emergency managers whose job is to prepare the community and its citizens for these storms and other disasters. For answers to specific questions you may have concerning hurricanes and preparing for them, contact your local Emergency Management Office.  However, a wide variety of information has been posted on this Web page.

How should I prepare for an evacuation?

Prepare a "disaster supplies kit" and put it in your vehicle. Make sure your car is in good repair and full of gas. Secure your home: turn off the gas, water, and electricity; board up the windows and draw drapes across them; brace garage doors; bring in or secure any loose objects in the yard; and lock all windows and doors. If you have a boat, secure it on a trailer near your house and fill it with water. Make arrangements for pets before you leave; most public shelters, and many hotels and motels do not allow them. Leave a note telling where you plan to go. Designate an out-of-area contact that family and friends can call to get information on your whereabouts. Finally, designate a meeting point for your family should you get separated.

The City of Sweeny urges residents who leave the area during hurricanes to e-mail us with your plans and contact information to assist emergency responders during times of disaster and recovery.  Use this link:

What if I need help to evacuate?

Arrange beforehand with friends or family to help you evacuate. If you have no one to turn or you have special needs, get in touch with your local officials now. They need to know who you are, where you live, and what kind of help you need so they can be ready to provide aid when a storm threatens.  Call the Sweeny Police Department to provide this information, or e-mail the information to us.  Use this link:  The information will be placed in a database for quick and easy retrieval in times of emergencies.

How long will it take to evacuate?

That depends on the size of the storm and the number of people who evacuate. Remember, the goal is to get everyone out of the threatened area before evacuation routes become impassable or unsafe due to flooding or high winds. This will happen when the storm is still many hours away from landfall. So, don't be surprised if there are no clouds and the sun is shining when local officials tell you to evacuate. Follow their instructions; your health and safety are their main concern.

Where should I go?

Inland...away from the coast. Use the evacuation routes shown on a map. Most of these roads are marked with blue hurricane evacuation signs. If you have friends or family at an inland location, arrange beforehand to stay with them. If you plan to stay in a hotel or motel, make reservations prior to departure to ensure you have a room. Cities and towns along the main evacuation routes may open public shelters, but these will be crowded and the "creature comforts" limited. If you need to use a public shelter, listen to your radio as you are evacuating to find out where shelters are open.

Returning Home

Returning home after a major disaster can be both dangerous and difficult.  Be careful entering a disaster area.  Before returning to an area that has been evacuated, make sure that local officials have advised it is safe to travel through areas between where you are and home.

Following a major hurricane, it may take several weeks to restore services and clear roads and several months to remove all the debris from the neighborhoods.  Be patient and also keep in mind that the better prepared you are, the less inconvenienced you will be.

Keep these tips in mind:

  • Return home only when authorities advise it is safe to do so.
  • Stay tuned to the radio (battery-operated) for information about available emergency assistance.
  • Drive only if absolutely necessary.  Avoid sightseeing.
  • Check for injured or trapped persons and provide first aid, if trained.
  • Wear heavy shoes or boots for protection.
  • Beware of snakes, insects, or animals driven to higher ground by flood water.
  • Enter your home with caution.
  • Open windows and doors to ventilate and dry the home.
  • Check food and water supply before using them.
  • Check your home for structural damage or defects.

Inspect utilities:

  • Check the gas, electrical, and water lines for damage. 
  • Check for fires and extinguish all open flames.
  • Check utility lines and appliances for damage.  If electrical wiring appears to be shorting out, close the switch at the main meter box or disconnect the main fuse.
  • Open windows and leave the building if gas appears to be leaking.  Call the fire department, police department, or gas company (City of Sweeny).
  • Plug bathtub and sink drains to prevent backup.
  • If water pipes are damaged, contact the water company (City of Sweeny).  Do not use water from the tap.  Obtain emergency water from hot water tanks, toilet tank (not bowls), and melted ice cubes.

Life may never return to "normal" for victims of a major disaster.  Experiencing a major disaster such as a hurricane can be a traumatic experience that changes peoples lives forever.  A sense of security may be lost and in most cases, there is some sort of property loss involved.

Tropical Storm Allison

When Tropical Storm Allison made landfall on June 5, 2001, its sustained winds were only 48 miles an hour, yet over the next five days, Allison dropped 38 inches of rain in parts of Southeast Texas causing widespread, catastrophic flooding.  Tropical Storm Allison was the costliest tropical storm in U.S. history.  For more information on this topic, visit the Tropical Storm Allison Recovery Project.
