What is the timeline for making weather related decisions?

Posted by:

For weather-related school closings, we aim to publish information by 5:30 a.m. whenever possible. If it is necessary to close school early, we aim to make an announcement by 11:00 a.m.

However, it is not always possible to adhere to this timing. Sometimes, we are not aware of a situation until a few minutes before school is due to start. ACPS gets the message to you as soon as we possibly can.
