Severe weather can strike at any time. The National Weather Service and the Weather Channel, as well as many local TV meteorologists all recommend the same way to protect your family. A weather radio can warn you of severe weather any time of day or night. Most new weather radios can even be programmed to only sound an alert for the county or counties that you select. There are different brands of weather radios, and they range in price from $20 to $100, which is a small investment to protect your family.
