Haverhill schools plan remote-only learning Tuesday with a two-hour delayed start. For the city’s public schools, the winter storm arrived early with freezing temperatures bursting pipes at two city schools over the weekend. Haverhill’s school superintendent said problems were caught before much damage could take place. Haverhill firefighters were dispatched to both Pentucket Lake and Paul C. Nettle Schools Sundays for freezing pipes. “No long-term damage. Fortunately, we caught it relatively early as we were monitoring schools for issues due to the cold across the weekend,” Superintendent Margaret Marotta told WHAV. Monday afternoon school activities and sports were cancelled.
