Non-Routine Programming:


During adverse weather conditions, some normal programming is suspended.   This is done to broadcast more important information frequently.

  • During severe thunderstorm and tornado watches, and flood warnings, the following will NOT air:  Climate Summary, Regional Weather Synopsis.

  • Most normal programming is eliminated during severe thunderstorm and tornado warnings.  Broadcast cycles are limited to severe weather watches and warnings, flood warnings, and Hourly Weather Roundup (local sites only).

When a severe weather watch or warning is issued, it is preceded by special alarm signals, which activate specially designed weather radios. These radios will alert you to the warning broadcast, through use of a siren or other means of notification. Radios that have the alarm feature and a battery backup are highly recommended. The cost of these radios range around $30, but may be as high as $80 for the programmable models, which allow you to screen out warnings that do not apply to your area. These radios can be found at many electronic stores.

In west central Illinois, the alarm features will be used for the following messages:

  • Tornado Watches and Warnings
  • Severe Thunderstorm Watches and Warnings
  • Flash Flood Warnings
  • Blizzard Warnings
  • Non-Weather Emergency Messages
  • AMBER Alerts (SAME only)

This alarm feature is tested Wednesday between 11 AM and noon.   If severe weather is a threat, the test will be held the first available good-weather day. is the U.S. government's official web portal to all federal, state and local government web resources and services.
