Well, all I know is it was predicted to have severe thunderstorms on the Sunday of the Glen. The other days were supposed to be better and they had one heck of a thunder and lightening storm one of the other nights. Granted it didn't have a hurricane or tropical storm headed there, BUT.... that was the NICEST of all the days that weekend. It was supposed to be the worst. It sprinkled in the early morning and was chilly. By mid-morning the sun was beating down and we were all dying in our warm weather clothes and taking off sweatshirts, jackets, etc. By the time the race started and after switching to "summer clothes", we were burning up in the grandstands with not a cloud in sight.
Especially with this being a Saturday night race, it's not like most people have to worry about taking a day or two off from the work to see the race. Just plan that the race might be rained out and you'll be seeing it on Sunday. Then again, maybe the storm will move through faster and it will be gone by the time the race starts.
While Gustav caused problems with electricity, etc., we watched it dropped down to a CAT 2 by the time it hit New Orleans. Thank God. I just hope this storm follows suit and just maybe, takes a different path out to sea.
