Weather Related Closing Guidelines

 closing guidelines

As we enter the winter months, D45 would like to update you on decisions that contribute to closing school in the event of a weather-related closing and when you can expect to be notified.

The District will follow these general guidelines when closing schools for winter-related closings:

Typically, school will be closed if there is a forecasted sustained wind chill of -30 degrees Fahrenheit or colder, or when the actual air temperature is a sustained -15 degrees Fahrenheit or colder between the travel times of 5:30 am and 9:00 am and/or 2:30 pm and 5:30 pm. The District will use forecasts provided by the National Weather Service.

For snow, ice, or other weather-related closings, the District will monitor the current conditions, the forecasted conditions between the travel times listed above, the ability of our staff to plow parking lots and sidewalks, as well as the ability of local municipalities to plow and make streets passable. The District will also be in contact with its transportation carriers to assess their ability to safely run buses. In these situations, the District will be in contact with local and State officials and meteorologists in order to make the most appropriate decision with the facts known at that respective time.

If school will be closed, the District will make every effort possible to make the notification by 5:30 am the day of the closing knowing that you may need to arrange for childcare or other schedule changes. If the District is able to make the determination the night before to close school – meaning the forecast undoubtedly warrants closure – the District will attempt to notify you between 6:00 pm and 9:30 pm.

Typically, the District does not send out a telephone SchoolMessenger notice after 9:30 pm, as the system can sometimes take up to an hour or so to complete all calls. However, if the determination to close school occurs after 9:00 pm, we will update D45 websites, social media accounts, and the Emergency Closing Center Website ( as soon as a decision has been made. The SchoolMessenger notice will also be sent prior to 5:30 am the following morning.

In the event of severe weather, information regarding afternoon and evening co-curricular activities, athletics and community education classes will be updated by 1:00 pm or whenever practicable on the District website at

As always, the safety and security of our students and staff remain a top priority of our District, as they are for you as well.
