...Have Redundant Methods to Receive Weather Warnings...

Today, a better understanding of tornadoes, new technology such as
dual pol Doppler radar, faster communications, and better Skywarn
storm spotting networks allow meteorologists to provide more
accurate and timely warnings for destructive tornadoes and severe
storms. But in order for the warnings to be effective people must
receive the warnings in a timely manner and take proper actions to
protect themselves.

The best way to receive severe weather watches and warnings is with
a tone alert NOAA Weather Radio All Hazards. A weather radio will
give you severe weather information direct from your local National
Weather Service office. Watches and warnings are preceded by a tone
alert that can automatically activate your radio and get your
attention with a high pitched alarm, even if storms hit in the
middle of the night. SAME equipped radios can be programmed to only
alert you to watches and warnings for a specific county, or group of

In addition, the radios can alert you to a non-weather emergency
such as a hazardous material spill or child abduction.

Remember, sirens are outdoor warning systems and should not be your
primary method of receiving tornado warnings.

Although not directly provided by NWS, there are many vendors who
provide weather apps for smart phones, which can send watches and
warnings to your phone.

The federal Communication Commission, Department of Homeland
Security, and National Weather Service have teamed up with the
nations wireless phone service providers who will broadcast Wireless
Emergency Alerts to mobile devices for tornadoes, flash floods and
other life threatening events. If you have a device that is capable
of receiving wireless emergency alerts and you are within range of a
cell phone tower that is in a warned area, you will receive an
alert. It will be like a text message but with a distinct tone. For
