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.
