It seems Florida is taking this one very serious. My cousin runs a division of a major tree trimming company in Texas and is now on his way to Florida with several crews.
Listening to the news on Florida this morning, all the keys and several other counties are under mandatory evacuation orders. While they are saying that all of Florida will likely be hit, they are also saying there is no need to leave the state and asking people to just buy enough gas to get them to the closest safe definition. They are also saying that there will be more mandatory evacuations as the storm progresses, so sounds to me like those going to the closest safe place, just may need more gas to evacuate again right in the thick of things. I am pretty sure I would fill up and try my best to get out of the storms path, if I needed to leave home.
