GSP Regional SKYWARN

A fast-moving squall line will impact our region this evening, lasting into the early hours of Friday morning. Wind fields and associated sheer will be very strong during this event and the threat of damaging winds and/or tornadoes is increasing. Heavy rainfall on the order of one to two inches will be possible, which may lead to minor flooding in some areas. This event will occur at night, so it is even more important to monitor local media/weather alert radios for rapidly changing weather conditions and to realize that quick action may be necessary in the event of a tornado or damaging winds.

For all those interested the NWS has added a new algorithm for radar during severe weather events which should make radar updates faster, you can read more here, FAQ: http://www.roc.noaa.gov/WSR88D?/PublicDocs/NewTechnology/AVSE?T_FAQs030910.pdf

GSP SKYWARN uses the repeaters in the SCHEART Linked Repeater System to operate during severe weather. There has been several changes to which repeaters we operate through. We will now be using the following repeaters.

VHF REPEATERS

145.370 PL 1230 – PARRIS MOUNTAIN, SC (GREENVILLE, SC)

145.470 PL 162.2 – ROCK HILL, SC

145.470 PL 123.0 – CAESAR’S HEAD, SC (GREENVILLE, SC) ***UNDER CONSTRUCTION***

UHF REPEATERS

443.125 PL 123.0 CAESAR’S HEAD, SC (GREENVILLE, SC)

441.625 PL 91.5 – GREENWOOD, SC

With more repeaters being added and configuration changes comng, this list is planned to change again. There is one more wave expected and then the final plan will be in place. The eventual plan will call for SKYWARN operations only being used on VHF. This will leave the UHF repeaters for ESF-8 or other misc purposes.
