Jim will let various people know that a storm is coming by the various repeaters in the area. Everybody in Franklin County would listen to the 146.985 repeater. Tom repeater, and the 146.910 Mt. Greylock repeater. Those are the main ones to listen to when the severe weather strikes. These repeaters are useful because there is so much activity going on at once, that these repeaters are monitored by Jim N1VMH and there is not as much traffic on them.
Any weather is important and can be reported when there is a informal net going on.
However, when the really severe weather happens, it is good to stick to only the important information. That way only the major stuff gets priority over the minor stuff. The important information includes winds in excess of 45 miles per hour, flooding, dime size hail, any funnel cloud, damage caused by lightning. Skywarn volunteers support their local community and government by providing the NWS with timely and accurate severe weather reports. These reports, when integrated with modern NWS technology, are used to inform communities of the proper actions to take as severe weather threatens.
