A Tornado Warning is issued by the local NOAA Office meteorologists who monitor the weather in the area. NOAA said they issue a warning when a tornado has been reported by spotters or indicated by radar and there is a serious threat to life and property in its path. During a tornado warning, you should act right away to find safe shelter.

During a Tornado Watch, tornadoes are possible in and around the watch area, according to NOAA. This means it is a good time to review your emergency plans. It is important to act quickly if a tornado warning is issued and if you spot one coming.

If you are home, be sure to quickly go to a safe room or an interior room away from windows, which could get blown out.

If you are in a workplace or school, be sure to follow your tornado drill instructions and head to your shelter location. Again, stay away from windows. NOAA also advises against going into large open rooms like a cafeteria or gymnasium.

If you are outside, seek shelter inside a sturdy building. NOAA said to avoid sheds and storage facilities.

If you are in a vehicle, you are advised to drive to a sturdy shelter. If you are not able to get to a shelter, get down into your car or abandon it and head to a low-lying area like a ditch.

Some tornadoes form without any warning, so it is important to know what to look for. According to NOAA, these are the signs to look for:

• Strong, persistent rotation in the cloud base.
• Whirling dust or debris on the ground under a cloud base — tornadoes sometimes have no funnel!
• Hail or heavy rain followed by either dead calm or a fast, intense wind shift. Many tornadoes are wrapped in heavy precipitation and can’t be seen.
• Day or night – Loud, continuous roar or rumble, which doesn’t fade in a few seconds like thunder.
• Night – Small, bright, blue-green to white flashes at ground level near a thunderstorm (as opposed to silvery lightning up in the clouds). These mean power lines are being snapped by very strong wind, possibly a tornado.
• Night – Persistent lowering from the cloud base, illuminated or silhouetted by lightning — especially if it is visually in ground contact or there is a blue-green-white power flash underneath.

Harris County is the second most tornado-prone county in the country, according to NOAA. So why don’t we have tornado sirens?

Emergency managers believe wireless alerts sent to cellphones are a better way to inform people about all kinds of hazards, including the type of tornadoes we get in Harris County.

Tornadoes in Harris County tend to be smaller and cause less damage and fewer injuries. On average, local tornadoes aren’t on the ground as long as the tornadoes seen in Dallas or Oklahoma.

Additionally, communities near chemical plants use sirens to warn of a Hazmat situation. If tornado sirens were added, emergency managers say people might be confused as to which threat is taking place.
