Some articles say 10% other say 15%, but a significant percentage of the US refining capacity is in the destruction zone from this hurricane. Almost all of those refineries are shut down right now because of the flooding and storm damage. There are concerns oil imports will be curbed after the refineries are back in operation because port facilities have been damaged. Gasoline prices will likely be going up, especially in the SE. That probably won't hurt EV sales, though the length of the shortage will determine the impact. If the shortage is long, that could encourage more people to think seriously about EVs.
