Seems like everyone has answered the initial question, but thought I would share how we do weather alerting in my county............
I've got both a VHF G1, and a VHF/7-800 G5, on which I have weather paging set up for both that includes on our local dispatch channels/talkgroups, and on the NOAA channels themselves.
In the G1 I have it set up with the paging stuff for my agency, the VHF conventional stuff for surrounding counties, as well as the NOAA weather freq's with the 1050 Hz tone as a Long C (Long Tone) for weather. There are two zones set up for weather. The first weather zone is set up to monitor and page, and the second weather zone is set up for Selective Call only. When the pager activates on the 1050 tone it's set up to sound the EAS ( Emergency Alert System ) tone since that's normally the first thing you think of when you hear it.
On our local VHF conventional & P25 system (7/800 Phase 1) system when a Thunderstorm Watch or a Tornado Watch is issued the dispatcher will hit either the standard or two tone "warble" alert tone to clear the talkgroup for an announcement. For Thunderstorm Warnings they will set off the Countywide/Storm Warning Quick Call II tones. If it's a Tornado Warning then they'll activate both the storm warning tones, along with our Long C Tornado Warning tone.
On my G5 I have two zones set up for weather just like I do on the G1 however it's rarely used for that. When the Long C activates on the G5 I have the alert for that tone set up with the EAS tone as well.
I live in the Piedmont of North Carolina, which is about 30 minutes north of Charlotte, and we usually have a pretty busy spring & summer storm system around here. Our local NOAA transmitter frequency is 162.5250. 99% of the time during storm season the G1 stays parked on that channel, including at night just in case, along with other times outside the season if severe weather is predicted (such as when we're expecting and significant snow storm, etc). Both the G1 & 5 work great for this.
