"Although overhead lines may have more exposure than underground lines to wind damage or collisions, underground facilities are more prone to flood damage, especially in coastal areas where exposure to salt water could cause an outage."
Hurricanes produce a lot of water, so it usually floods the underground facilities, either that or the overhead lines that feed the underground lines go out. Since underground lines cost 15x more than overhead lines, they are usually only used for subdivisions...
