  1. 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. 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 Sterling. Trained spotters get the number in class; anyone can use the form.

  3. 3 · Tell the room here

    /report hail quarter · 71st & Memorial in #va-wx puts it in front of everyone watching the state. It does not reach the NWS - do 1 or 2 for that.
