It"s the beginning of the wet season in the Florida Everglades, where it"s typically hot and humid from May through November. Afternoon thunderstorms are common, bringing heavy rainfalls that subside quickly. The largest subtropical wilderness in the US, the Everglades is essentially a slow-moving river, 60 miles wide and over 100 miles long. The water flows during the wet season from Lake Okeechobee southward across a limestone shelf to the southern tip of the Florida Peninsula. The complex ecosystem here is not found anywhere else on the planet.
