ANNUAL SPOTTER TRAINING VIA THE NET FEB. 24 & MAR. 3

SKYWARN Spotter Training will be offered on the CCS Information Net on Feb. 24 & March 3 at 9:15 PM on the 146.88 repeater as part of the Severe Weather Preparedness Week.

This training may used to earn initial spotter certification or renew certification which is required every three years.

Part 1 of Basic Training will be Feb.24 ; Part 2, March 3. The instructor will be Nick Petro WX3H, Warning Coordination Meteorologist with the Raleigh National Weather Service.

To fully benefit from this training and to receive a spotter number, you must:

A. download the training presentation before each net from www.centralcarolinaskywarn.net  (It will be included with the Weekly Weather Impact Briefing.  Click on the Weekly Weather Impact Briefing on the top menu to download.)
B. listen and check in at the end of both nets, and
C. email CCS Emergency Coordinator Virginia Enzor at nc4va@nc.rr.com with your name, call sign (if licensed), spotter number (if already assigned) and email address.  The NWS will then contact you about completing the spotter certification process.

Scanner listeners and listeners receiving live streaming audio on the internet at www.broadcastify.com may also participate by downloading the presentations and emailing Virginia Enzor at nc4va@nc.rr.com immediately after both nets. Again, be sure to your name, call sign (if licensed), spotter number (if already assigned) and email address.

SKYWARN RECOGNITION DAY 2014

SKYWARN Recognition Day 2014 officially takes place Saturday, December 6 from 0000-2400 UTC.  Over 100 National Weather Services offices across the nation, including the Raleigh National Weather Service, are expected to participate in this annual event.

SKYWARN Recognition Day was developed in 1999 by the National Weather Service and the American Radio Relay League to celebrate the contributions that SKYWARN radio operators/spotters make to the National Weather Service.  During a 24 hour period, SKYWARN operators visit NWS offices and contact other radio operators across the world.

Central Carolina SKYWARN, operating under the call sign WX4NC, will join in the fun on Friday night (December 5) from 7-9 PM and Saturday from 9:00 AM to 5:00 PM, making contacts on the WB4TQD 146.88 repeater, the K4ITL 147.105 repeater, the K4ITL 147.135 repeater, the Carolina 440 UHF Link System, IRLP (node 9219), Echolink (WX3H and WX4NC), and HF (10, 15, 20, 40 & 80 meters SSB).  Ask a SKYWARN operator on the 146.88 repeater for our frequencies.

Radio operators will exchange names, call signs, locations, signal reports, and a 1or 2-word weather report.

A QSL card will be available for this event. Stations logging a contact with WX4NC may send a SASE envelope to the following address to receive a QSL card:

National Weather Service
Raleigh Forecast Office
1005 Capability Drive, Suite 300
Centennial Campus
Raleigh, North Carolina 27606

Hope to get you in the log!

SKYWARN SPOTTER CRITERION CHANGE

Per the direction of the Raleigh National Weather Service, Central Carolina SKYWARN will no longer take reports of “1 inch or more of rainfall in an hour’s time or less.”  The NWS has determined that this amount of rainfall does not necessarily result in flooding and therefore should not remain a criterion to report.  We will continue to take reports of “flooding and flash flooding where none normally occurs.”  This change was effective September 4, 2014.
