Thanks Peter and Karl Hopefully things will be OK on Wednesday. It is
only an hour flight so I guess we could come back here if it doesn't work
out. Driving isn't much better with Snoqualmie pass only one lane each way.
At least if a drive, I could cart more stuff back from the Beoing Surplus
store!

We will be flying (hopefully) to Bremerton, WA (KPWT) on Wednesday and
the weather in the PNW does not look very good either now or in the
forecast (widespread fog, vis 1/8sm). Are there any local fog effects at
Bremerton? Are there airports in the area that are not as likely to have
fog? Which ones? Thanks!

As Karl says, the current weather pattern is one of widespread fog.
You're unlikely to find significantly different conditions at Bremerton
than elsewhere. However, on some days the fog burns off an hour or so
before sunset, and the distribution of this can be somewhat variable. So
toward the end of the daylight hours, some places may still be fogged in
while other places may not be.

As far as alternates go, I'd disagree with the claim that Boeing Field is
reliably the best weather when conditions are foggy. It often is, but it
really depends on the nature of the fog. If the fog has a little bit of
elevation to it, then Boeing Field, being so close to sea level, can be
landable (at least IFR). This is the current situation.

But if the fog is right down to the water, then KBFI will be fogged in,
while some of the airports at higher elevators may actually be fog-free,
or at least will have the fog burn off earlier in the day. This would
include Sea-Tac Airport and Paine Field (Snohomish County Airport).

Also, getting away from the water can sometimes improve things. So (for
example) Arlington Airport could have better conditions than Paine Field.
But we don't really have that many airports far enough away from the water
to help.

All that said, unless you have Cat II or Cat III capabilities, you should
anticipate that on this Wednesday, you might not be able to land anywhere
in or around Puget Sound, including Bremerton. Make sure you've got a
good alternate somewhere else (and just getting on the other side of the
Cascades might not be sufficient...at this particular instant, it would be
good enough -- though still not good VFR -- but it can get just as foggy
over there sometimes).

On top of all this, forecasts for when the fog will dissipate cannot be
trusted. The fog could clear hours before they say it will, or it could
not clear at all. It's important to know the forecasts (and of course
current conditions), but I'd say that around here, fog-related forecasts
are about as unreliable as weather forecasts get (other than "there will
be fog" ), and that's saying something.

Sorry to not have better news. Hopefully, Boeing Field will remain a good
alternate. On the bright side, if you wind up landing in Seattle, you can
easily take a ferry from there to Bremerton. That's always fun.
