Suggest or fix one →

What to report, and where

Size charts and the full guide →

🌪️ Tornado, funnel, wall cloud

·Tornado on the ground (say if you see debris)
·Funnel cloud - rotating, not touching down
·Wall cloud, especially a rotating one
·Where it is relative to you, and which way it's moving

🧊 Hail

·The largest stone, compared to a coin or ball (chart below)
·1″ (quarter) is the severe threshold - smaller is still worth a report to most offices
·How long it fell and whether it's covering the ground

💨 Wind

·Measured gusts of 40 mph+; 58 mph is severe
·Damage: trees down, limbs bigger than your arm, roof or structure damage, power lines
·Say whether it was measured or estimated

🌊 Flooding

·Water over a road, especially moving water
·Creeks and rivers rising fast or out of their banks
·Rainfall of 1″ or more in an hour if you have a gauge

❄️ Winter

·Snowfall of 1″ an hour or more, and totals
·Freezing rain and ice accumulation on wires and trees
·Visibility under ¼ mile, blowing and drifting

🚫 Not this

·Lightning and thunder on their own
·Rain that isn't causing flooding
·Ordinary dark clouds, scud, or clouds that only look scary

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 Green Bay. Trained spotters get the number in class; anyone can use the form.
3 · Tell the room here
/report hail quarter · 71st & Memorial in #wi-wx puts it in front of everyone watching the state. It does not reach the NWS - do 1 or 2 for that.
