Communication is an important part of emergency planning. Basic communication items such as emergency whistles and dynamo crank/solar powered NOAA, FM, AM, SW and LW radios are essential parts of an emergency kit.
During a disaster, it will be important to be able to listen in on emergency response updates and/or weather reports. This is a vital link to let you know what's going on outside and possible rescue efforts on the way or pending bad weather approaching or easing up.
