[Naturens] Sable Island ?

Hi All, I've been following 'Teddy's' onslaught on NS with interest and I'm particularly impressed with the wave and storm surge heights - possibly 20+ metres offshore. Is a chance that Sable Island could be overtopped - or nearly so - by a rogue wave or storm surge event. There are only a few scattered spots on the island over 20 metres so it seems theoretically possible. Is there any record of it - or something close happening in the past? All the best.
