According to county commissioners, the evacuation order was out of caution.

“Better to be safe than to be sorry,” said County Commission Chair Janet Long. “And we have decided to err on the side of caution and protect our citizens.

"When people think about this storm, remember those folks in South Florida have already started evacuating and the highways are bumper to bumper traffic right now. So those of us in Pinellas County that want to leave the county are going to be faced with getting in the midst of all of that ongoing traffic and then you’ve got to be concerned with whether or not you’ll be able to get a sufficient enough of gasoline to get out of the state.”
