Students are returning to a Massachusetts high school on Monday after heating issues shut down the building last week.
School officials shut down Lowell High School to allow maintenance workers time to fix ongoing heating issues in the building.
According to the Lowell Sun, a voice message to families and staff was left by Head of School Marianne Busteed on Sunday saying that officials had been closely monitoring the ongoing heating problems and that contractors were in the building daily.
"Although all the necessary repairs are not complete, we feel enough progress has been made to bring students and staff back tomorrow," Busteed said in the message.
Pictures of the cold conditions at the school had been shared on social media. One mother showed NBC Boston a video of a pipe bursting inside the school's gym.
Senior Matt Draper said he was so cold in class that his hands were turning purple.
"Nobody was able to pay attention because everyone was focused on how cold they were and trying to stay warm any way they could," Draper said.
The Lowell city manager's office said issues with the heating system have been going on for more than a month.
According to the high school's Twitter account, the school semester will be extended a week due to the missed days.
