Case Study: Lawrence Academy protects students and staff from severe weather with DTN WeatherSentry

Why Lawrence Academy relies on WeatherSentry and meteorological consulting to make the tough calls.

Lawrence Academy, a 140‑acre independent college‑prep school serving about 400 students in Groton, Massachusetts, faced recurring safety challenges from lightning and New England winter storms. After unreliable results from consumer apps and rooftop detectors, the academy needed accurate, timely local forecasts and alerts to make decisions about suspending play, protecting outdoor crews, and deciding when to call maintenance or cancel services. To address this, Lawrence Academy turned to DTN and its Platinum sports edition of WeatherSentry plus DTN’s meteorological consulting services.

DTN implemented its commercial‑grade WeatherSentry system with patented lightning alerts and on‑demand meteorologist consultations, providing instant notifications and precise short‑term forecasts. The solution gave staff enough lead time to delay or cancel events, pull teams from fields, alert vendors and maintenance crews, and avoid costs from unused services like buses and police details. According to Lawrence Academy, the speed and accuracy of DTN’s meteorologists and alerts have improved planning, reduced losses, and increased safety and liability reassurance for students, staff, and contractors.
