Central and western Wyoming's 2020 Severe Weather Awareness Week will occur from Monday, May 11th until Friday, May 15th. It is the National Weather Service’s mission to protect life and property and during this week NWS Riverton will be stressing the importance of severe weather safety and the importance of preparing and planning for various natural disasters that impact Wyoming.  Having a practiced plan ahead of time can make the difference between life and death.

Each day this week will focus on a different type of severe weather and include safety information related to each type. Click on one of the tabs above to learn more.  The lineup for 2020's Severe Weather Awareness week is:

Monday, May 11: Severe Storms (Large Hail and damaging Winds)

Tuesday, May 12: Lightning Safety

Wednesday, May 13:  Tornado Safety.

Thursday, May 14: Flood Safety

Friday, May 15: Fire Weather

NWS Riverton will not be conducting a tornado drill this year. However, you are encouraged to become familiar with safety rules and make plans to protect yourself and your family when storms develop. If an actual tornado warning was issued, it means a tornado has been sighted or indicated on radar and people should take shelter immediately. Tornado warnings are disseminated through NOAA weather radio, local television and radio stations, cable television systems, and outdoor warning sirens.

Wyoming is served by five National Weather Service offices. We issue watches and warnings for the protection of life and property. For additional information, contact your local NWS office:

Staying Aware of the Weather

Ready, Set, Go: This is the mindset we want people to be in when it comes to being prepared for hazardous weather.

Before Severe Weather Season: Develop an emergency plan and practice it regularly.

Here are a few questions to ask when developing your plan:

  • What is your risk for a natural disaster?  Do you live in a flood prone area? Knowing your risk can help you develop a plan tailored to your family.
  • Where do you go in case of a natural disaster?  Is it a basement such as during a tornado, or to higher ground during a flash flood?
  • Do you have a designated meeting place for your family if you get separated? During a natural disaster, phone service might be disrupted, and getting in contact with loved ones might be difficult.
  • What would you do if basic services such as water, gas, electricity, or telephones were cut off?  Having an emergency supply kit in your home and car is essential.  It is recommended that you keep enough supplies in your home to meet your needs for at least 3 days.  After a natural disaster, it could take a while for emergency responders to reach your location.
  • How will you be notified of a natural disaster? What about at night?

Ready: At this stage, the National Weather Service sees something on the horizon that may end up being a widespread severe weather event in the future. The Hazardous Weather Outlooks and Situation Reports issued by the local NWS offices will give you this information. Also, the Storm Prediction Center issues thunderstorm outlooks that give an idea of where severe thunderstorms may develop in the next 8 days. At this stage, you should make sure your emergency plan and supply kit are up-to-date.

Set: In this stage, we are confident that a hazardous weather event will occur, but are not sure of the exact timing, location, or impact of the event. For severe thunderstorms and tornadoes, a Watch is issued to give the public a heads up that they need to be prepared for the possibility of severe weather within the next 8 hours. At this stage you should keep abreast on the latest weather conditions, and be ready to implement your emergency plan at a moments notice.

Go: When we hit this stage, we are confident that a thunderstorm will be soon producing severe weather and at this point a Warning will be issued. The lead time can be just precious minutes out to an hour. At this stage, you should activate your emergency plan.

FEMA, the Red Cross, local emergency management, and the National Weather Service can help you develop your plan. Here are a few websites with guidance in making your emergency plan:
