I checked on it this morning when I got to the office. The gum has survived blizzards, ice storms, blazing heat, lightning storms, an earthquake, fair weather with moderate temperatures, and now a hurricane. (Okay, it was probably a tropical storm.) I don't think anything short of a volcanic tornasteroid will knock it off the ledge.
The Weather Channel says there's a volcanic tornasteroid forming in the south Atlantic, but it's currently projected to veer off to the east.
