Keep in mind that by now, the major roadways away from the coast may have already been changed to "exit only", which means that traffic is one way only, away from the coast. Thia means that the traffic on both sides of a divided highway will all be traveling in the same direction.
In addition they have been reporting gas shortages in many areas of the State as people fill up to leave, or to have fuel if they decide to stay.
Stay safe and use common sense. If you can't leave the area, try to find a big box store where you can park next to a high building to shield you from the wind as much as possible. Between two building is the best and keep away from any trees that could blow down.
I should add that when the roads are made one way exit only, it may be several days after a storm before they are put back to normal. If there is extensive damage, they still do not want people to come back in to an area while emergency crews are working and supplies are brought in.
