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.
