Weatheradio

A weather radio service is a broadcast service which airs special weather-related emergency broadcasts and announcements. Weatheradio services may also broadcast non-weather related emergency information, such as in the event of a natural disaster, an AMBER alert or a terrorist attack. They generally broadcast on a special VHF frequency audible only with special "Weatheradio" receivers or radio frequency scanners, although in some locations a weatheradio broadcast may be retransmitted on a conventional AM or FM frequency, and some television stations broadcasting in MTS stereo transmit weatherradio on their second audio program (or SAP) channel.

Weather radios come with several features that make them very helpful in case of an emergency. Some models use crank power, in addition to eletricity and batteries, which is a life saver in case of an electricity outage or if you are located in an unserviced area (for example, camping in a forest). Some models have an embedded flashlight and can double as a cell phone charger .

Weather radios are sold in the majority of electronics stores. Their price varies depending on the model and its extra-features. It can range from 15 US$ to more than 70 US$ on the US market [ [http://knol.google.com/k/rachid-lakhal/stay-informed-to-stay-safe/22wi6bg36bbc7/2#H0-1-Weather-alert-radio Stay Informed to Stay Safe] ] .
