Extreme cold: In very cold weather, school districts may close or delay the opening of schools if the temperature drops below a certain threshold, especially when coupled with factors like wind chill. This is because extreme cold can pose health risks to students and staff, such as frostbite and hypothermia. The exact temperature at which schools close can vary from district to district, but common thresholds might be around -20 degrees Fahrenheit (-29 degrees Celsius) or wind chills below a certain level, such as -40 degrees Fahrenheit (-40 degrees Celsius).
Snow and ice: Heavy snowfall or icy conditions can also lead to school closures or delays. Snow and ice can make roads hazardous, making it difficult for students and staff to travel safely to and from school. Decisions regarding school closures due to snow and ice are typically made by local school officials in consultation with local law enforcement and emergency management agencies.
Other weather-related factors: Apart from extreme cold and snow/ice, other weather conditions that can potentially cause school closures include high winds, flooding, thunderstorms, and power outages. School districts will consider the specific weather conditions and their impact on student and staff safety when making decisions regarding school closures.
Communication: When school closures or delays are necessary, school districts will typically communicate this information to families, students, and staff through various channels, such as the school website, phone calls, text messages, and social media. It's important for families and students to stay informed about potential school closures by regularly checking these communication channels.
