Rain, rain, go away
It's raining so hard I can't even see the other side of the valley, 500m away. Every time there's a storm in the Caribbean we get the fallout a few days later. So I guess what we're seeing here is the side-effects of Charley. When Mitch rolled through Honduras and Nicaragua we got practically incessant rain for twelve days. A couple of Costa Ricans were killed in a landslide, but the toll in Honduras and Nicaragua was 12,000.
Fortunately, due to the Coriolis effect, it's virtually impossible for a hurricane to make landfall in Costa Rica. By the time it gets to this longitude, it will have veered off to the north.
