True, they do cost. However, it is damned if you and damned even more if you don't and fail. EM has the worst job. They have to play it safe. If there is a chance of a high Cat2 low Cat 3 near the Tampa area [Lets not forget that the forecast actually has a range either side of the line that is within its designated range], I think EM will have to evacuate, even if they do think that it will go in further south. A simple wobble could be a tragic disaster. EM will be roasted for evacuating if the storm goes to Ft Meyers instead; but they have no other good choice.
