My personal opinion is that the pager as well as the web pages and the
wind* lists are for determining the conditions before leaving or en route
to the launch to see whether it's worth going or switching destinations
on the way. Upon arrival, sailors should use their own sensors (whatever
they may be), calibrations, and judgment before launching from a given
site with given equipment. I'd say that if you schlog all the way across
the channel in search of wind in a flood on a flukey day, that you're
asking for trouble.
As for Tuesday's readings, I'd say the Coyote readings were a bit high
for the inside, but accurate for the outside. I think sometimes there
truly are large differentials between the two sites. Usually the closer
you usually are to the gap means more wind, which makes it all the more
important to oppose runway expansion.
