A major power outage hit the Las Vegas Convention Center around 11:15 a.m. PT, just as the second day of CES 2018 was ramping up. It came a day after more than an inch of rain fell in Las Vegas, which caused flash flooding the desert city. (Wednesday's weather is clear and warm, and it's unclear if the power outage was at all related.)

As of 1:06 p.m., there were reports that some of the lights were returning to life in the Convention Center's Central Hall, where the blackout was first reported. That area houses the giant booths for show mainstays including Sony, Samsung, LG and Intel -- though Samsung's booth still had limited electricity thanks to its own private backup power. By noon, security guards were refusing entry to parts of the Convention Center.
