Tornadoes are extremely violent storms featuring rapidly rotating columns of air that connect clouds to the earth’s surface. The strongest tornadoes can have wind speeds over 250 mph, occasionally reaching 300 mph, and cause damage paths over a mile wide and 50 miles long.

The most powerful tornadoes are produced by supercell thunderstorms. These storms develop when horizontal wind shears rotate the storm, and updrafts tilt this rotation vertically, forming a rapidly swirling column of air that can touch the ground and create a tornado.

PREPARING FOR A TORNADO:

• Know the signs of a tornado. 
• Listen to local officials and register for AlertHouston to stay informed. 
• Pay attention to official weather reports.
• Identify and practice going to a safe location. Protection includes a small, interior, windowless room or basement on the lowest level of a sturdy building.
• Plan for your pet. They are an important member of your family and need to be included in your family’s emergency plan. 
• Prepare for long-term stay at home or shelter in place by gathering emergency and cleaning supplies, non-perishable foods, water, medical supplies and medication. 

STAYING SAFE DURING A TORNADO:

• Immediately go to a safe location that you have identified.
• Protect yourself by covering your head or neck with your arms and putting materials such as furniture and blankets around or on top of you.
• Stay clear of fallen power lines or broken utility lines.
