In wave, in blue hole at cloud level, hole closes, in IMC, then what?

To put the hangar talk into perspective, here is a quote from John Good:

"Wave flying is dangerous - one of the more dangerous activities that humans voluntarily engage in. With experience and care, the risks can be lowered, but not eliminated. Some aspects of safety in wave and mountain flying are presented here, but this is far from a
complete discussion, and some of this material is not aimed at beginners. Pilots should strive to develop the judgment that will keep them safe, understanding that mountains such as these can present conditions in which even excellent aircraft and skilled pilots cannot safely fly."

Mt. Washington poses some unique challenges (like the downwind wilderness) but it shares commonalities with other wave flying sites.
