Pinellas County, FL. SKYWARN
What is SKYWARN? • Volunteer program consisting of trained spotters who provide severe weather reports to the National Weather Service. • Currently around 290,000 trained spotters.
Who is SKYWARN? • Persons of all backgrounds who share an interest in severe weather and a desire to serve their communities. • Private citizens, police officers, emergency management personnel, etc. • Amateur Radio operators form the back-bone of the SKYWARN program.
Why do we need SKYWARN? • Spotter reports provide critical ground truth. • Severe weather detection technology can only indicate the existence of hazardous conditions. • Radar effectiveness depends on the size and height of the storm and it’s distance from the radar. • Only one instrument can identify and report severe weather with absolute accuracy…the Human Eye!
Spotter reports... • Fill in the gaps left by radar. • Help forecasters issue more timely and accurate warnings by providing reports of actual conditions on the ground… • ...and confirming the existence of hazardous weather detected on radar. • Provide verification information, helping to improve future warnings • Improve public response to warnings due to confirmation.
Did you know? • Spotters first used during WWII to alert artillery plants of lightning? • After the May 25th, 1955 tornado in Udall, Kansas killed 80 people, the NWS decided to train their own severe weather spotters? • First spotter training class held on March 8th, 1959 in Wellington, Kansas for 225 spotters? • Program officially created in 1965? • As of June 2008, there were 3,243 spotters in WCF, 748 of them ham operators.
