You didn't say what kind of a rig you have for SHTF escapes. That would have a lot to do with what I would do.
Questions:
Do you have a snorkel on your rig.
Has your rig height been modified.
Do you have aggressive tires.
Do you have plenty of gas, water, food, clothing etc.
Do you have a winch and tow straps, tools etc.
Do you have a chain saw.
If you don't have all of these things, leave before it gets there or ride it out if you have a safe space like a school or Government buildings or concrete block structures. Right now it looks like it will be a tropical storm but you cant second guess mother nature. I'm sure I have only touched on the subject of evacuation and I hope others will be more helpful. Stay safe
Some background: I have lived through all hurricanes that have passed through Florida over the last 24 years. I was just a kid but I remember riding out all the 2004 hurricanes at home cause of where we were located inland. Since then I have moved a town over in a house that is now all block. Our safe spot is a 10 acre piece of land with a house, barns, and shelter with generators, easy access to well water, near fresh water streams that feed into the St Johns river and plenty of wild hogs. The area on that land where the structures are located is cleared of any trees that could fall near them but is surrounded by all sides of trees to protect the structures from wind. My girlfriend drives either her little VW Passat, her father's Ford Ranger 4x4 or his F350 dually 4x4. We have plenty of options.
I have a 2015 Tacoma 4x4 stock. I have used 2wd suvs in the past during storms with a lower clearance so I know how to deal with the conditions well..
For where I am at I don't need to have a snorkel cause of how high the land is compared to the coast. Flood waters only go up to road levels.
I have all terrain tiers on my rig now that came from the dealer but I am looking to switch them out soon.
I have plenty of supplies on hand to last at least a few months and if need be on food I can either catch some fish near where our safe spot. It does help that I buy gas every few weeks for the four wheelers so I have plenty of cans full.
Both my truck and my girlfriend's fathers trucks have tow straps and he has a wench. If need be we have plenty of was to rescue our vehicles.
As for evacuation routes we know that 95 will be a mess but as close to 17 which goes north, 44 and 40 that can take us up 75. We know the round about ways to get north with less traffic that will be safe.
As of 7 this morning, it will be a Cat 2 at landfall and they are projecting to hit on Sunday around 2 in Bervard County.
