How's the fog in SEA today? I live and work near YVR (Richmond, BC) and we've been fogged-in for days, especially close to the strait, which is where the airport is.

Not sure how all these ILS categories apply but they were talking here yesterday about some of the smaller planes (these could be anything from float-planes that depart from the Fraser River to the smaller regional aircraft) in particular having cancelled flights because while they had the minimums necessary for take-off they couldn't meet the minimums for landing if they had to return to YVR for some reason.

Looks like quite a few delays and cancellations this morning so far.
