Severe Weather Season Information
TornadoTornado Watch

Issued by the National  Weather Service when conditions are favorable for the development of tornadoes in and close to the watch area. During the watch, people should be prepared to move to a place of safety if threatening weather approaches.

Tornado Warning

Issued by the National Weather Service when a tornado is indicated by radar or sighted by spotters. People in the affected area should seek safe shelter immediately.

Tornado Emergency

A Tornado Emergency is issued by the National Weather Service. It is not a new warning, but is used to highlight a confirmed tornado which is expected to be strong and violent. A Tornado Emergency means that significant, wide-spread damage with a high likelihood of numerous fatalities is expected to continue.

Remember, outdoor warning sirens are just that, outdoor warning. The sirens are meant to be heard outside to signal you to go indoors and tune your radio or television station to the local Emergency Alert System (EAS) Station.

What Do The Sirens Mean?

No matter what you are doing, any time you hear an outdoor warning siren go off, you should always find shelter, take cover, and if possible turn on a radio or TV to a local station for more information and possible emergency instructions.

NOAA Weather Radios

The NOAA Weather Radio is the primary indoor warning system. Like a smoke detector, NOAA Weather Radio waits in a standby mode until a watch or warning is issued.
The NOAA Weather Radio can be programmed for your local area or your favorite vacation spot. There are now portable weather radios that can be used to supplement and outdoor warning system. NOAA Weather Radios can be purchased at most “big-box” stores.

Where to Listen for More Information?

DO NOT CALL 911 or local fire or police agencies to ask why the sirens are sounding. If it is an emergency, they are busy getting equipment and resources to the emergency scene.
When you hear sirens sound in Story County, tune to your local Emergency Alert System (EAS) station for further information.

Take Cover!!!

To “take cover” means to go inside immediately. The sirens sound when it is not safe to be outside. Make sure that everyone in your family knows the safest place to be in your home during an emergency.

During a severe weather emergency a basement or other underground shelter is the safest place to be. Try to get under a heavy workbench or the stairs.

If you do not have a basement, stay on the first floor and put as many walls between yourself and the outdoors as possible. A closet or bathroom on an inside wall, or hall-way on the lowest level of the house. Try to shelter away from windows.

If you live in a mobile home or trailer, get out!! Even if it is tied down a mobile home can be shattered . It is important to identify the closest safe place before an event. If you do not have a storm shelter in your park, learn where storm shelters are located in your community and have a plan on how you will get there.

If you are outside or in a car, get out of the car and inside a house or building. Do not try to outrun a tornado in your car. You can be picked up and thrown by the tornado. If you are caught outside, crouch low in a ditch and cover your head with your hands
