Weather Alerts

During the winter months, colder temperatures can bring inclement weather and poor driving conditions. Sunnyvale ISD will closely monitor weather conditions and communicate any changes to our normal school operations with families.

Should it become necessary to cancel classes, games or events, or delay the start times, SISD will provide the school community with information in a timely fashion. The decision to cancel classes or delay the campus start time will be made as early as possible.

The SISD community may access information in the following ways:
