Get out. Move north and west. Anything within 200 miles of the coast and within 200 miles immeadiately to the east of it's path will be destroyed. If you live between panama city and new orleans get OUT!
This is unprecedented.. because of the population density and the road network, getting out may be impossible at this point. Get a topograpical map, know where high ground is close to your location AT ALL TIMES. Bring a shovel to dig for wind shelter from flying debris.. structures are NOT shelter in these circumstances. The winds will be bad.. but the storm surge will kill you. GET TO HIGH GROUND, then seek shelter from the wind by digging. Do it before it's too late.. winds over 60mph will kill with debris, over 80 will just blow you away. This things packin winds over 150mph.
Anybody got a link to a topographical survey of the area? Best place would be 30' above sea level & have a nearby road network to get you outta the disaster area to water and food stocks immediately after the passage of the storm... because if you ain't out of the area now it's likely you'll not make it out because of traffic and panic. BEFORE you travel, go with a a topographical map so you can evac from the road to high ground if your caught in the open on the road.
Aftermath.. no clean water, low food stocks... could be very very dangerous. Go armed if you can.
Good luck, god bless.. prayers are with you.
