I haven't looked at the exact new track. Find the Surge Models or levels for your county, then look at the area you live in. If it says you need to go, grab some things and go. Do Not Wait if you live in an area that is low, has been ordered or suggested to evacuate.
Ask your neighbors, especially the long timers, how the area held up during Andrew. If they want to stay let them, but if you even think you need to go. Get Out Right Then. The roads will become clogged, the bridges will be out of service and you Will be riding the storm out in a car.
If your significant other says they want to go. Leave right then and go with them!
