Alternative Resources for Severe Weather Alerts and Updates

The Town of Prosper is committed to ensuring the safety of our residents and providing all accessible resources for your protection.

Wireless Emergency Alerts (WEA): Most residents receive automatic flash flood notifications through the WEA system. These alerts, which do not require any opt-in, are delivered directly to your phone based on your location. They are accompanied by a loud ringer or vibration to ensure immediate attention.

Rave Alerts: Rave Alert is a free service that provides emergency information directly to your cell phone, email, and/or landline. By opting into Rave Alerts, you will receive automated weather warnings and other emergency alerts issued by the National Weather Service (NWS) - Fort Worth. This can include notifications for shelter-in-place or evacuation orders, hazardous materials incidents, and various severe weather warnings such as:

  • Tornado Warning

  • Flood Warning
  • Flashflood Warning
  • Ice Storm Warning
  • Winter Storm Warning

Prosper’s Outdoor Warning System (OWS)

The Town of Prosper has 11 outdoor warning sirens designed to alert residents during emergencies, including severe weather, hazardous material incidents, and civil defense situations. View the Outdoor Warning Sirens Location Map to see siren locations.

When Are Sirens Activated? Sirens will sound when:

  • The National Weather Service issues a Tornado Warning or a Severe Thunderstorm Warning with winds over 70 mph for Prosper.
  • Trained storm spotters report a tornado in or near the Town.
  • Hail 1.5 inches or larger is reported.
  • Other emergencies, as determined by Prosper Emergency Management.

What to Do When Sirens Sound

  • Seek shelter immediately in a windowless, interior room or lowest level of a sturdy building.
  • If outside, move indoors. If no shelter is available, lie flat in a ditch or low area. Avoid bridges and overpasses.
  • Stay informed by monitoring local news or weather alerts.

Monthly Siren Testing

Sirens are tested on the first Wednesday of each month at noon unless severe weather is present.

Emergency Contacts

  • For emergencies, call 911.
  • For non-emergencies, call 972-569-1000.

Tornado Watch vs. Tornado Warning

Understanding the difference between a Tornado Watch and a Tornado Warning is crucial for your safety during severe weather:

Tornado Watch: This means conditions are favorable for tornadoes to develop. A tornado has not yet been spotted, but conditions are right for one to form. Stay alert and monitor the weather for updates.

Tornado Warning: A tornado has been sighted, either visually or on radar, in the area. If a warning is issued, take immediate action to protect yourself. Find shelter in a safe area, as tornadoes can strike quickly and without much warning.

Safe Areas in Your Household During Severe Weather

During severe weather, including tornadoes, it’s vital to have a plan and know where to go for shelter. Here are some safe areas in your home:

  • Interior Room or Hallway: If you don’t have a basement, go to the center of the home, away from windows, and ideally in a room with no exterior walls. A bathroom, closet, or hallway are good choices.
  • Small, Windowless Room: The key is to avoid large, open rooms with windows. A bathroom, closet, or small interior hallway is the safest choice.
  • Under Stairs: If you can’t reach an interior room, shelter under sturdy stairs for additional protection.
  • Avoid staying in mobile homes, vehicles, or near windows during severe weather events. If you’re caught outside, lie flat in a low-lying area, such as a ditch, and cover your head.

Power Outage Resources

  • If you are experiencing a power outage, check the Oncor outage map for updates or report an outage by calling 888-313-4747.
  • For residents in the CoServ service area, check the CoServ outage map and report an outage by calling 855-938-3496.

Stay Informed

While our sirens alert you to go inside and seek further information, ensure you are equipped with multiple methods of receiving alerts. Utilize weather apps on your phone and stay tuned to local television broadcasts for the latest updates and safety instructions. Your safety is our top priority, and we encourage you to make use of these resources to stay informed and prepared during severe weather conditions.
