Information about the weather is gathered from many sources, including The National Weather Service, Accu-Weather, the news media and by actual inspection of roads, school driveways, and sidewalks throughout the county. Weather conditions in surrounding counties are also gathered and factored into forecasting conditions for Montgomery County students and considered for those students attending non-public schools in other areas. Information from these various sources is factored into the decision.
Weather conditions or continuing impact from severe weather or other events such as a widespread power outage, may cause a delayed opening, early closing or closing for the day. The most severe conditions within the county are used as the basis for the decision-making criteria. A uniform procedure to close all schools is maintained so that the school system can respond quickly to emergency conditions and protect the safety and well being of students and staff who attend both public and non-public schools and receive transportation services from Montgomery County.
