Subject:   NOS/CO-OPS is implementing model guidance SHEF

           Bulletins for the San Francisco Bay Operational

           Forecast System (SFBOFS), Effective March 12, 2014


Effective March 12, 2014, at 1900 Coordinated Universal Time

(UTC), NOS/CO-OPS will implement SHEF bulletins containing water

level model guidance generated from the new SFBOFS.  The

bulletins will be disseminated under the WMO Header SOUS43 KWBC

with and an AWIPS ID of TIDSF.


The SFBOFS will produce 48-hour model guidance of time series

data updated every 6 hours. The SFBOFS SHEF bulletins will

contain the full 48-hour model guidance at 30-minute intervals

and will be updated every 6 hours based on the 03Z, 09Z, 15Z and

21Z model cycle. Model guidance in the SHEF bulletins is

provided at locations where CO-OPS has or historically had water

level stations installed, and they are identified by an NWS

Location Identifier (NWSLI). Modeled water levels are total

water levels: astronomical tide plus non-tidal effects. CO-OPS

models are not designed to provide reliable storm surge

guidance, although meteorological conditions such as winds and

air pressure are taken into account.
