A date/time group appears in the first column. The first two digits represent
the day of the month. The next four digits represent a time, in Greenwich
Mean Time (or Z time). Z time is seven hours ahead of Pacific Daylight
Time (PDT) and eight hours ahead of Pacific Standard Time (PST). Data
in the next six columns is wind speed and direction for each of the six
coastal wind observation sites. Wind direction is a three-digit number
and represents the direction the wind is blowing from (in degrees). The
pair of two digit numbers after wind direction are current sustained wind
speed, and peak wind during the past hour. Wind speed is reported in knots.
A "00" for peak wind speed means data are missing.
The first row of numbers (set off with dashes) represent data from 24
hours ago. The second row of data is the most recently collected data,
with the previous hour after that etc. A partial list of wind data appears
below, with an interpretation following it.
