Emergency crews responded Monday to reports of a fire and explosion involving an underground power transformer in Omaha, Nebraska. The explosion occurred in a utility vault under the sidewalk next to the DoubleTree Hotel, acting Battalion Fire Chief Mickey McLaughlin said, according to the Omaha World-Herald. No injuries were reported as of late Monday, and the area around the hotel was temporarily blocked off. Guests at the hotel said they felt their rooms shake and saw smoke. "We started walking down eight flights of stairs. As we’re doing that, the building was shaking a bit and the lights were flickering on and off," said hotel guest, Andrew Lovato-Needham, according to Omaha's WOWT-TV.
