Staying safe during severe weather

Information collected and assembled by students with the Creighton University College of Nursing. The City of Grand Island is StormReady®.  Are you?

Grand Island and Hall County are home to a wide variety of severe weather hazards which can include severe summer storms bringing wind, hail, heavy rain and tornadoes to winter blizzards and ice storms.  The most effective way to learn of severe weather is to monitor local media and especially the NOAA All-Hazards Weather Radio. 

Severe Thunderstorms

Thunderstorms can produce heavy rain, strong winds, lightning, hail and tornadoes. You may need to respond promptly to one of these threats posed by a storm in your area.

The National Weather Service, in cooperation with the broadcast media and your local spotter system, will provide you with the warnings you need to quickly respond. If you listen to the media, you will know when a storm is approaching your area and you will know if you need to take protective action.

A Severe Thunderstorm Watch means conditions are right for the development of storms. Stay tuned to the media for further advisories.

A Severe Thunderstorm Warning means a storm is probable in the warned area and residents there should be prepared to take cover. Don’t wait until an emergency siren sounds to start looking for flashlights and other things. Plan ahead!

When severe storms threaten, keep alert. Stay tuned to the media for current information. Know where to find shelter. Pick the safest spot. Make sure the entire family knows where to go – at home, at work, in school, at the mall – anywhere they might be when the storms strike. Avoid traveling. If you live in a mobile home, you should make sure the mobile home is securely anchored. During storm warnings, you should seek more secure cover and have a plan that includes abandoning your mobile home.

Tornado

Tornadoes are the most destructive and devastating product of a thunderstorm. These violent “twisters”, are characterized by a twisting, funnel-shaped cloud, which forms from the bottom of a wall cloud and touches the ground. Tornadoes are often accompanied by lightning, heavy rain and hail.

A Tornado Watch is issued when conditions are favorable for tornadoes to develop. Be prepared to take action.

A Tornado Warning is issued when radar indicates a tornado, or a funnel cloud has been sighted. Seek shelter immediately.

In an average year, the United States reports 800 tornadoes Resulting in 80 deaths and 1,500 Injuries. While they can occur all year, They are most common during the Spring in the Great Plains, where they develop along “drylines”, which separate very warm, moist air to the east from hot, dry air to the west. Tornado producing thunderstorms may form as the dryline moves east during the afternoon hours.

Nebraska is in the middle of tornado alley and each year the state averages 35 tornadoes. Knowing tornado safety is your best hope for surviving. You must have a plan. Stay tuned to the media when the watches are sounded and be prepared to seek shelter if a tornado warning is issued in your area.

Seeking Shelter
The safest place to be when a tornado strikes is in a basement under something sturdy like a workbench. If your house does not have a basement, seek shelter in a small room in the middle of the house. A closet or a bathroom is best. The more walls between you and the approaching storm, the better. Have a  portable radio and flashlight handy to take with you.

If you live in a mobile home, even those with tie downs, seek more sturdy shelter. Go to a prearranged location like a neighbor’s house or a nearby structure with a basement. As a last resort, go outside and lie flat on the ground with your hands over your head and neck.

In an automobile, never try to outrun a tornado. Tornadoes create flying debris that cause severe injury. Get out of your vehicle and seek a safe structure or lie down in a low area with your hands covering the back of your head and neck. Keep alert for flash floods.

At work or school know that emergency shelter plans. If no specific plans exist, go to an interior hallway or small room on the building’s lowest level. Avoid areas with glass and wide, free span roofs. In a store or shopping mall, if you can’t get to a basement or designated shelter, go to the center of the lowest level of the building. Avoid windows and lie flat. Cover yourself with any sturdy object.

Flooding

Floods kill more people on average than tornadoes and lightning combined and most flood deaths are due to flash floods. Flash floods are often the result of heavy rains associated with severe thunderstorms. You will not always have a warning that these deadly, sudden floods are coming.

When a Flash Flood Watch is issued, be alert and be ready to evacuate on a moment’s notice.

When a Flash Flood Warning is issued, or the moment you realize a flash flood is imminent, act quickly to save yourself. You may only have seconds!

Nearly half of all flash flood fatalities are auto related. In your automobile, look out for flooding at highway dips, bridges, and low areas. Do not drive through flowing water. A mere two feet of water will carry away most automobiles.

Severe weather can present serious hazards.  Establishing a good plan today and being aware of watches and warnings for your area will allow you to make timely and safe decisions.
