I don't have a strong feeling on this matter, but it is not the average increase that matters. Every small increase in average has a multiplier effect on storm surge. http://www.pnas.org/content/early/2017/10/23/1715895114. Nonetheless, my guess is that the real threat is to general property close to the shore, not the terrestrial cables even though they are not waterproof (only submarine cable can handle long term immersion).
