I will bet you $10,000 FRbucks that they are prepared, they're safe, and that they'll be fine.
Yes, it is my assumption that someone who's previously climbed Denali, Ranier, the Andes, and the Alps would go up sufficiently prepared.
Right now they are self-rescuing by laying low, which is the smart and proper thing to do.
I hope you're right. The weather's really nasty here and going to get worse in the days to come. They've already been a lot of days up there... And it's a bit disconcerting that ~something~ separated them from each other.
Then wouldn't they have sent another cell phone call during the recent weather lull? Is it reasonable that 3 experienced climbers would schedule their climb to coincide with the onset of a well-forecasted severe storm?
Not that I'm disagreeing with you but perhaps they're 'laying low' in Mexico.
