Dear friend,

Perhaps understandably I've been spending too much time on the Tropical Storm Risk site these last few days.

It's a bit silly, but it's very addictive. One minute it looks like Dean is going to hit Mexico City as a Cat 2 and then its hundreds of miles away.

I wonder when was the last time the Capital of Mexico got hit by a full-blown Atlantic hurricane?

Anyway I remembered that I wrote a bit about the Yucatan when Wilma was doing its worst in 2005.

The storm surge in Chetumal looks awful, but for everyone else, even those with nothing more than wooden shacks to protect them, one great thing about the local geology is that you can always go and shelter in the nearest cave (provided you watch out for the water level).

Fingers crossed.
