Nascar will stop a race for rain if someone so much as spills a beer in the parking lot. Motorcycle races are rarely delayed or cancelled due to weather.
Florida weather is a bit different than most of the U.S. of A. Rainstorms can be so small (yet strong) that it is raining on a sunny day. This makes an ideal situation to photograph rain. Notice anything about the tires here?
They have no tread; these are roadracing slicks.
Ten or twenty minutes after the rain has stopped we can see that most of the track is fairly dry. Fortunately for us spectators, some puddles remained throughout the next few heats.
