About Skywarn

Skywarn is an organized group of trained weather

observers. A Skywarn group exists in virtually

every US county with a signiﬁcant population.

During inclement weather, reports made by

Skywarn observers include information about:

• Pea-sized and larger hail

• Wind and wind gusts of 40 MPH and greater

• Heavy rainfall

• Lightning (cloud-to-cloud and especially

cloud-to-ground)

• Wall clouds seen in severe thunderstorms

(which spawn tornadoes)

• Severe lowering of a wall cloud

• Turbulence in a wall cloud

• Funnel clouds

• Tornadoes

• High water areas

• Downed power lines

• Other emergency conditions that affect life

or property

Listen to Skywarn to hear trained observers in

your vicinity call in ofﬁcial reports to a net control

station which relays those reports to NOAA and

other emergency agencies. Listen to NOAA for

weather alerts and warnings, watch box notices,

and weather forecasts.

Note: If you tune to a Skywarn frequency

when the Skywarn net is not active, you may

hear nothing, or you may hear amateur radio

operators talking on a local repeater system.
