Skywarn
The skywarn function lets you jump directly to the
last channel in memory (Channel 200) from any
mode by pressing FUNC +
. The scanner goes
into scan hold mode and starts receiving
transmissions in the last channel. If no frequency is
programmed in the last channel, No Prg appears
and the scanner sounds an error tone.
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 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
