Update: Just checked all four cams at about 630pm. Three of them are stuck on 6 p.m. timestamps, and the camera near St. John Spice hasn't seemed to change for 10-20 minutes. Looks like it's lights out.
The storm is coming. Here are links to four Webcams on the island. Watch 'em as long as the power stays up.
