CNN PRODUCER NOTE Crystal Cabot and William Cabot Boyd were taking a lunch break during their overnight shift when they heard a coworker screaming early Tuesday. “We saw the fire 6 miles away with flames from 50 to 130 feet high, depending on the explosions occurring,” said Cabot. Once they got there, they saw that Red River Supply in Williston, North Dakota, was the site of the fire. People within a half mile of the scene are being evacuated this morning after the explosion and fire, according to CNN affiliate KVLY.
