Subject:   NOS/CO-OPS is implementing model guidance SHEF
           Bulletins, Effective December 5, 2012.

Effective December 5, 2012, at 1500 Coordinated Universal Time
(UTC), NOS/CO-OPS will implement SHEF Bulletins for CO-OPS
Operational Forecast System (OFS) water level model guidance.

CO-OPS produces SHEF bulletins of observed water level and
meteorological data as well as astronomical tides.  A new set of
SHEF bulletins will be generated with total water level model
guidance from the 13 operational CO-OPS OFS models. Ten OFS
models produce 48-hour model guidance of time series data updated
every 6 hours, and three models provide 24-hour model guidance
updated every 6 hours.

Model guidance is provided at the CO-OPS tide gauge locations.
Thus, the OFS Water Level SHEF bulletins will contain the full
48-hour or 24-hour model guidance of 30-minute data, and will be
issued every 6 hours to remain consistent with the OFS output.

Modeled water levels are total water levels (astronomical tide
plus surge). It is noted that CO-OPS models are not designed as a
storm surge model though meteorological conditions, such as winds
and air pressure, are taken into account. Although the
Operational Forecast Systems produce model guidance of currents,
water temperature, and salinity, these data will not be included
in the SHEF bulletins; however, they can be viewed and downloaded
at the CO-OPS Web site. The Great Lakes SHEF OFS data will be in
Local Standard Time (LST), whereas the rest of the OFS data will
be in UTC, to meet user requirements.
