Steps to Prepare

Houston residents should start taking steps to prepare for the arrival of storm conditions.  This includes:

Avoid Roadways

All roadways are vulnerable to dangerous flooding during an intensive rain event.  The Department of Public Works & Engineering and the Office of Emergency Management have produced a map of roadway segments and underpasses that are especially prone to flooding - pictured below.  If residents are unable to suspend all travel during the duration of this storm, they should heed special caution around these locations.  If you see a barricade in your path, DO NOT drive around it or move it.  Barricades are put in place explicitly to protect lives.


Have a Plan

Evacuations for this storm system in the City of Houston are unlikely, but may be possible  for coastal areas. It's always a good practice to know whether or not you live in an evacuation zone. Most residents in the City of Houston will not be in an evacuation area. (for a map of the zones, click the graphic below)

Find your evacuation zone

Some residents who live outside of the evacuation area, but who live in mobile homes, or other structures that cannot withstand the winds associated with a hurricane should consider evacuating.

Additionally, anyone who is medically-dependent on electricity may plan to evacuate, as power may be out for several days.

If you are unable to evacuate yourself, or may need additional assistance due to a medical or other need following the storm, register with the State of Texas Emergency Assistance Registry by calling 2-1-1 or visiting


Only those who need to evacuate should.

If you plan to evacuate, you should:

  • Identify where you are going and how you are getting there.  For a map of official evacuation routes, click here. 
  • Make sure you have what you need ahead of time.  This includes
    • Food, Water, Clothes and Medication for 3-5 days
    • Carriers for your pets
    • Enough cash for 3-5 days.
  • Identify a family member or friend who lives out of the Houston area to serve as your family's central point of contact.  Write down their phone number and when you arrive at your location, check in with them.


If you place to shelter-in-place, you should:

  • Identify where you will shelter in your home.  This should be an interior room on the lowest floor possible. If you live in a flood-prone area, you may also want to have a back-up plan to evacuate to a higher floor.
  • If you live in a high-rise building, you should consider where you will shelter, interior hallways with no windows are ideal, or seek shelter in a substantial structure elsewhere.

Prepare Your Kit

Regardless of whether or not you decide to evacuate, you should have what you need.  The City of Houston recommends having supplies for 5-7 days. Remember, it will take time for stores, ATMs, banks, and other resources to reopen, depending on the level of damage and power outages.

Prepare Your Home

  • Trim tree branches and limbs that might slam against your home or roof
  • Secure loose rain gutters and clear clogged areas.
  • Prepare to secure windows and doors with durable plywood. For specifics on how to do this, visit the Federal Alliance for Safe Homes website at
  • Purchase a portable generator and prepare it for use. Remember to only use generators at doors at least 20 feet from the home.

Stay Informed

When tropical weather is beginning to form, and during storm impact, its important to remain informed.  Ahead of time, stay aware of conditions by following information from the National Hurricane Center and the National Weather Service Houston/Galveston Forecast Office.
