Nope my cousin is from Los Membrillos and my uncle is from a little town called San Nicholas not to far from Chapala and I had my cousin check in from Manzanillo.
Ah, I was there first then ran a thrift store in Ajijic. It may as well all be counted as one big city down there with the way the bus system connects the close-proximity towns and everyone gets around.
I heard from someone there that Chapala already went through one rough time when the lake had receded far in then restored after a lot of rain, flooding businesses that had built in closer to the water. The government put in a lot of money to restore it and make it a weekend getaway place for Guadalajara, in part to also encourage further foreigner retiree settlements (they have nothing to do but be old and spend money).
Because of that and the military being so familiar with the towns due to cartel activity, I'm hopeful for relief efforts going smoothly, but this storm surely made some really big messes that will be difficult to manage. I hope the US helps out properly. It looks like the storm tracked more west into the mountains where not many people were settled, so hopefully it ended up the least damaging it could have been for what it was.
There were some ghost neighborhood places in Guadalajara, so if a lot of people end up more permanently displaced that may be something that helps them, but I'm not sure. They apparently evacuated a lot of people to there.
