Hurricane Dean And The SW Monsoon

After having crossed the Yucatan Peninsula, Hurricane Dean's eye is just crossing back over water, this time over the Bay of Campeche, before hitting Mexico proper and dumping tons of rain on those steep mountain slopes.

Global interconnections are all. After having started off the west coast of Africa, the weather forecasts show that by Sunday, a lot of Dean's moisture will have worked its way up the western coast of Mexico, and will contribute to the thunderstorms of the desert monsoons of the American Southwest.
