Skywarn is a program of the National Weather Service (NWS). Its mission is to collect reports of localized severe weather. These reports are used to aid forecasters in issuing and verifying severe weather watches and warnings, improve the forecasting and warning processes, and the tools used to collect meteorological data. It consists of a network of severe storm spotters that observe weather conditions and make reports of severe weather to their local NWS offices. These spotters are trained by personnel from the local NWS offices each spring in advance of the coming severe weather season.
The NWS office in Cleveland services the counties from Toledo to Erie, PA, from Lake Erie to just north of Columbus. Frequencies of county nets, district nets, and the backbone are available for Hams or scanner listeners on the NWS Cleveland Skywarn Amateur Radio Operations page. Skywarn Spotter Training happens in March and April, just before severe weather season.
Cuyahoga County Skywarn:
LEARA supports NWS Skywarn operations. The 146.760 repeater is used as the primary repeater and the 146.880 repeater is used as the backup repeater for Cuyahoga County Skywarn. Live Internet audio can be found on our Streaming page.
The Skywarn Practice Net takes place every Wednesday night at 8:00 PM local time on the 146.760 repeater. This net runs during severe weather season, mid-February through the end of October. See our Nets page.
Skywarn is typically activated when the National Weather Service has issued a watch, warning, or when weather conditions potentially threaten life and property in Cuyahoga County.
If, at anytime, a QSO is taking place on any frequency and a Skywarn Net Control Station breaks in and needs the frequency for Skywarn operation, the stations carrying on the QSO must sign and make the frequency available for Skywarn.
Stand By Mode:
Stand by mode typically means there is severe weather in the area or there is an active warning for a nearby county. This is signified by a a Morse-code "S" (· · ·) courtesy tone on the repeater. The Skywarn Net Control Station is monitoring the frequency for emergency traffic or to put the repeater in severe weather mode. Stations may use the repeater to carry on QSOs but must leave long pauses between short transmissions so stations with priority traffic may break in.
Severe Weather Mode:
When Cuyahoga County Skywarn is activated, the repeater will be put into severe weather mode. In severe weather mode, the courtesy tone will change to a Morse-code letter "W" (· - -) which signifies the repeater is closed and in a directed serve weather net. Stations may only transmit if they have a report that meets the criteria as directed by Skywarn Net Control.
