Tornados, tropical systems and severe thunderstorms with straight-line winds cause hundreds of deaths and billions of dollars in property losses annually in the U.S. with an average of 750 tornados annually.
While all severe weather poses threats, tornados are particularly dangerous because, unlike a tracking hurricane, it is difficult to determine when or where a tornado may strike, and the sustained winds of even a F1 tornado on the Enhanced Fujita Tornado Intensity Scale can reach 110 mph.
That means residents as well as the public-safety personnel protecting them need to be aware of wireless applications for advanced tornado alerts. Such alerts can provide fire department personnel time to react before the tornado touches ground and what departments can do to provide appropriate shelter for personnel in a tornado's path.

Constructed with 10-gauge hot-rolled ASTM 1011-CS Type B steel, Guardian meets FEMA 320 and FEMA 361 and ICC-500 standards and is tested to withstand the EF5 tornado missiles test conducted by the Texas Tech University’s (TTU) Wind Science and Engineering Research Center.
- Storm Shelters and Safe Rooms from Secural: These above ground tornado shelters comply with the recommendations established in the documents FEMA 320 and ICC-500. The shelters passed the F5 tornado missile Impact resistance tests at TTU.
Storm Shield Weather Radio
The Storm Shield Weather Radio app turns a wireless device into a NOAA emergency weather radio. The user receives storm-based alerts for tornado, hurricane, flood, thunderstorm, winter storm seasons and other life-threatening weather events via voice and push notification. The app can receive critical alerts via voice and push notification alerts other users, like family members, which have been added to an individual's preferences within the app.
Tornado by American Red Cross App
Free for Android and iPhone, the American Red Cross Tornado app features an audible siren when NOAA issues a tornado warning for any of the monitored locations imputed by the user. The app lets a user know when it is time to go to a safe room plus an all-clear alert when the warning expires.
The app also includes step-by-step instructions to help you know what to do even if cell towers and TVs are down. Prioritized actions for before, during, and after a tornado requires no mobile connectivity
Available for Android and iPhone on the Verizon network, WeatherBug Protect is a collaborative effort between Verizon Wireless and WeatherBug. The app turns a Verizon Wireless mobile device into a weather notification device, providing advanced warning of lightning, tornadoes, extreme temperatures, flash flooding, high winds, hurricanes and more.
The app taps into the WeatherBug Network of U.S. weather sensors, providing real-time, local alerts integrated with notifications from the National Weather Service. The app also monitors potentially threatening weather conditions, including lightning activity, severe storms, heavy rainfall, high-heat index, high-wind gusts and more. It also delivers real-time lightning warnings and is linked to the intracloud and cloud-to-ground lightning detection network.
Wireless Emergency Alerts
The CTIA, a wireless industry trade group, along with the Federal Communications Commission and Federal Emergency Management Agency, developed the Wireless Emergency Alerts (WEA) to send concise, text-like messages to users' WEA-capable mobile devices. The service became operational in 2012.
WEAs use a point-to-multipoint system, which means alert messages will be sent to those within a targeted area, unlike text messages which are not location aware. For example, if a person from Southern California has a WEA-capable device, but happened to be in an area outside Tulsa, Okla., the device would receive an imminent-threat alert when a tornado warning is issued for the affected area of Oklahoma.
