Subject: Test of Operational Rip Current Valid Time Event Code
(VTEC) in Coastal Hazard Message at Select Weather
Forecast Offices (WFOs) Effective May 12, 2011
Effective Thursday May 12, 2011, at 1200 Coordinated Universal
Time (UTC) 10 additional WFOs will use a new VTEC event code for
rip currents in their Coastal Hazard Messages (CFW).
These WFOs will begin using the new VTEC event code RP.S within
the CFW, instead of CF.S or LS.S, when specifically targeting an
increased Rip Current Risk. The RP.S will be operational (i.e.,
the VTEC line will carry the (O) identifier). The Rip Current
information issued by these offices will be highlighted in
turquoise on the NWS Watch, Warning Advisory map at
http://www.weather.gov

The remainder of NWS coastal and Great Lakes offices will
continue using the VTEC event codes CF.S or LS.S in their
Coastal/Lakeshore Flood Statements (CFW) when a Rip Current
threat exists. No actions are necessary to continue processing
the CF.S and LS.S VTEC event codes.
This test of the new VTEC event code (RP.S) within the CFW by
the WFOs specified in Table 1 will continue until further
notice, unless significant negative feedback is received.
Users are encouraged to provide feedback by using the brief
survey and comment form on the Internet at:
