Subject: Test of Beach Hazards Statement with new Valid Time
Event Code (VTEC) in Coastal Hazard Message at
Select Weather Forecast Offices (WFOs) Effective
May 15, 2012
Effective Tuesday May 15, 2012, at 1200 Coordinated Universal
Time (UTC), six NWS Weather Forecast Offices will use a new VTEC
event code for beach hazards in their Coastal Hazard Messages
(CFW).
These WFOs will begin using the new VTEC event code for the
following BH.S: Beach Hazard Statement within the CFW instead of:
CF.S: Coastal Flood Statement
LS.S: Lakeshore Flood Statement used in the Great Lakes
RP.S: Rip Current Statement used at 17 coastal WFOs when
specifically targeting hazardous conditions that are occurring or
likely to occur along a beach, coastal area or shore and their
immediate adjacent waters.
The Beach Hazards Statement, with the headline of "Hazardous
Beach Conditions in effect for [timeframe]" will inform
beachgoers and local authorities of a multitude of hazards
including, but not limited to:
- rip currents or other types of dangerous currents in the surf
zone
- unusually cold water temperatures
- potential for lightning along the beach/shoreline
- high heat indices which do not meet advisory criteria
- unusual surf/wave conditions which do not meet advisory
criteria.
In coordination with other agencies, as needed, the product may
also inform users of various types of environmental hazards
(e.g., chemical spills, harmful algal blooms, high bacteria
levels in the water, or potentially hazardous marine wildlife
which may be impacting the area.
The Hazardous Beach Conditions Statement is intended to provide
information for these types of hazards in a single product. The
examples of hazards provided above will not necessarily apply to
all NWS coastal offices because each office has unique criteria
for their area of responsibility.
The BH.S will be operational, i.e., the VTEC line will carry the
(O) identifier. The Beach Hazard information issued by these
offices will be highlighted in turquoise, same color as rip
current statement, on the NWS Watch, Warning Advisory map at:

Table 1: Communication identifiers for the CFWs issued by the
6 WFOs that will use the new VTEC for Beach Hazards (BH.S)
effective May 15, 2012:
Issuing WFO WMO Header AWIPS Id

Tampa Bay Area, FL WHUS52 KTBW CFWTBW
Customers must make the appropriate changes to their systems in
order to process the new VTEC BH.S.
The remainder of NWS coastal and Great Lakes offices will
continue using the VTEC event codes CF.S, LS.S, and RP.S in their
Coastal/Lakeshore Hazard Message (CFW) when there is a threat of
hazardous beach conditions. No actions are necessary to continue
processing the CF.S, LS.S, and RP.S VTEC event codes.
This test of the new VTEC event code (BH.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:
