SUBJECT: Comments Sought through June 30, 2013 on New
Webpage
for Forecast
and Observed Wave Information
NWS is seeking
comments through June 30, 2013, on an experimental
marine Webpage. The NWS Weather Forecast Office
(WFO) in Eureka,
CA, has developed
a graphical vector plot of predefined point
guidance for up to six wave systems (direction,
height, and
period) and wind (direction, speed) through a 5-day
period at
6- hourly increments. If the point is associated with a buoy
location, the previous 24 hour observations,
partitioned in the
same manner as the forecast waves, are plotted in
3 hour
intervals. The forecast wave information is from the
partitioned
Simulating
Waves Nearshore (SWAN) model output. The wind is
forecaster derived.
NWS marine users
can use the Hanson Plots to quickly assess the
wind and sea conditions out to 5 days. The
Webpage highlights
trends in the conditions and helps users obtain
favorable and
hazardous conditions.
Because observed
buoy data is also presented in the same format,
users can evaluate the current conditions and
forecast conditions
at the same time. Users also can assess how the
forecast is
performing in the near term relative to current
conditions
because both views are on a plot for locations that
have buoys.
NWS forecasters
also use the Hanson Plots to determine which sets
of wave data (up to a maximum of six individual
wave systems)
will be used as initial guidance for the official
gridded
forecast.

Hanson Plots, see

For a description
of this new product, see
https://products.weather.gov/PDD/HansonPlots_Extension_PDD%20.pdf
To provide
feedback, see
http://www.nws.noaa.gov/survey/nws-survey.php?code=HPGT
The feedback
period will run through June 30, 2013.
At the end
of the feedback period this product will be
considered for
national implementation.
Feedback, and
questions, can also be sent to:
