Potential for Severe Weather on Sunday Continues

What is the danger?

The potential for severe weather continues for Sunday, including the threat for tornadic activity. The possibility for heavy rainfall, thunderstorms, damaging winds, hail, and flooding may increase by the afternoon. Heavy rainfall could lead to rapid rises at area streams, creeks and bayous due to the recent rains. Although the potential for tornadoes is greatest in the morning, this should be monitored throughout the day, because the weather can change quickly.

The Harris County Office of Homeland Security & Emergency Management will be staffing its Emergency Operations Center to support public safety needs.

What You Should Do:

Residents should monitor local media and the National Weather Service for the latest forecast and have multiple ways to get warnings on Sunday should severe storms develop. Various watches and warnings may be issued through Sunday evening. Be prepared to act quickly to protect yourself and your family. Below you will find useful life-saving tips.

Basic Flood Safety Tips

  • Turn Around, Don’t Drown! ® DO NOT DRIVE through high water and DO NOT DRIVE AROUND BARRICADES! Just 2 feet of water can sweep your vehicle away.

  • DO NOT WALK through flood waters. Just 6 inches of moving water can knock you down. 

  • If your home floods, STAY THERE. You are safer at home than trying to navigate flooded streets on foot.

  • If floodwaters rise around your car but the water is NOT MOVING, abandon the car and move to higher ground. Do not leave the car and enter MOVING water.

  • STAY AWAY from streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.

  • MOVE important items – especially important documents like insurance policies - to the highest possible floor. This will help protect them from flood damage.

  • DISCONNECT electrical appliances and do not touch electrical equipment if you are wet or standing in water. You could be electrocuted.


    If a tornado warning is issued for your area, seek shelter immediately. First rule of safety is to get low and stay low, others are listed below:

  • Go to an interior room on the first floor, such as a bathroom, closet, or room without windows.

  • If you are outside, take cover in a low spot away from trees.

  • If you are in a mobile home, get out and go to a secure shelter.

  • If you are in a car, get out and take shelter inside a nearby sturdy building.

  • Avoid highway overpasses. Parking or taking shelter under a bridge or overpass is extremely dangerous due to flying debris and the possibility the structure may collapse.


In the event of thunderstorms, stay inside. Remember: When Thunder Roars, Go Indoors!

Here are lightning safety tips from NWS:

  • Avoid open fields and stay away from tall, isolated trees or other tall objects. If you are in a forest, stay near a lower stand of trees.

  • If you are camping in an open area, set up camp in a valley, ravine or other low area. Remember, a tent offers NO protection from lighting.

  • Stay away from water, wet items, such as ropes, and metal objects, such as fences and poles.

  • Stay off corded phones. You can use cellular or cordless phones. Don't touch electrical equipment such as computers, TVs, or cords. You can remote controls safety.

  • Avoid plumbing. Do not wash your hands, take a shower or wash dishes.

  • Protect your pets: Dog houses are not safe shelters. Dogs that are chained to trees or on metal runners are particularly vulnerable to lightning strikes.

  • Protect your property: Lightning generates electric surges that can damage electronic equipment some distance from the actual strike. Typical surge protectors will not protect equipment from a lightning strike.
