Subject: Experimental Beach Hazards Statement will become

         operational effective May 4, 2015

         

Effective Monday May 4, 2015, the Experimental Beach Hazards

Statement will transition to operational. The Beach Hazards

Statement is approved for all coastal NWS offices to issue when

they determine there are unusual or hazardous conditions in the

surf zone or at a beach in their area of forecast responsibility.

The Beach Hazards Statement provides beachgoers and

local authorities with significant information related to

hazards, actual or potential, which currently do not have NWS

watch, warning or advisory products. This includes, but is not

limited to:

 

- Dangerous currents in the surf zone

- Unusual surf/wave/tide conditions not meeting advisory criteria

 

Coastal NWS offices issue Rip Current Statements to inform

beachgoers of the potential and risk level for rip currents.

 

Since 2012, 20 coastal Weather Forecast Offices (WFOs) have been

testing the Experimental Beach Hazards Statement (Table 1). NWS

received comments from May 15, 2012, through December 31, 2014. 

Based on positive feedback for the experimental product, NWS will

transition the Experimental Beach Hazards Statement to the Beach

Hazards Statement.  

 

The VTEC code for the Beach Hazards Statement will be the same as

for the Experimental Beach Hazards Statement: BH.S. Users do not

need to make any adjustments to their systems.
