Have to say it's not looking great at the moment: http://www.cancuncare.com/forum/tem.../20945-tropical-storm-rina-headed-cancun.html Please remember though these weather systems can increase or die out totally. Too early to say 5 days away, but lets hope for the latter.
Holy cow I just booked the 31st through the 4th before I looked at the radar! First and foremost I hope Cancun is spared any damage, but a close second is that I hope it clears out by Monday....I hate drinking in the rain.
There's a huge thread running about the hurricane over on the Temptation Forum that you might find interesting: http://www.cancuncare.com/forum/temptation-resort-cancun/20945-hurricane-rina-headed-cancun.html
