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
marineWebpage. The NWS Weather Forecast Office (WFO) in Eureka,
CA, has developed a graphical vector plot of predefined point
guidancefor 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
samemanner 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
forecasterderived.
NWS marine users can use the Hanson Plots to quickly assess the
windand sea conditions out to 5 days. The Webpage highlights
trendsin the conditions and helps users obtain favorable and
hazardousconditions.
Because observed buoy data is also presented in the same format,
userscan evaluate the current conditions and forecast conditions
atthe same time. Users also can assess how the forecast is
performingin the near term relative to current conditions
becauseboth views are on a plot for locations that have buoys.
NWS forecasters also use the Hanson Plots to determine which sets
ofwave data (up to a maximum of six individual wave systems)
willbe used as initial guidance for the official gridded
forecast.

To provide feedback, see

The feedback period will run through June 30, 2013.At the end
ofthe feedback period this product will be considered for
nationalimplementation.
