Decisions about unscheduled school closures and bus route changes are almost always made in the early morning before school. This allows for the most current weather information to factor into the decision. This information is communicated immediately, generally before 6:15 AM.
For more information about the district's procedure on unscheduled school closures, please review the attached Administrative Procedure #317 Temporary School and Classroom Closure or visit https://www.mpsd.ca/District/weatherprocedure/Pages/default.aspx#/=.
