Have heard that warning many times and therefore have always planned the run early morning to minimize the chances of finding out for myself. Just fine by me on the way in, but it hurts a little to cut the morning fishing short on the way out. This upcoming trip for instance, looks like the best weather window we will get to fish the outside is the day we leave. Is what it is I guess. I have always figured be through Muchalat before 11am. I imagine what the tide is doing when those outflows start up plays a role too.
