- 1 · The net, if one is up
When the office activates SKYWARN, a net control on the local repeater takes reports in a set format and relays them straight to the forecaster. Listen first, check in when asked, keep it short: who, what, where, when.
- 2 · The office directly
No net running? Every office has a spotter line or online report form on its SKYWARN page - for you that’s NWS Calera. Trained spotters get the number in class; anyone can use the form.
- 3 · Tell the room here
/report hail quarter · 71st & Memorial in #al-wx puts it in front of everyone watching the state. It does not reach the NWS - do 1 or 2 for that.
