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.  Also, hourly weather reports will be limited to nearby stations only.

  • 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 $20 upward.  Click here for more information on weather radio receivers. 

In southeast 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 feature only)

This alarm feature is tested on Wednesdays between 10 AM and 1 PM.   If severe weather is a threat, the test will be held the first available good-weather day.
