• Coaches, staff, and administrators are expected to exercise good judgment in evaluating the appropriate activities given the current conditions and adjusting activities appropriately.

• Site administration needs to monitor conditions for all “away” athletic competitions and ensure these guidelines are being followed for our TUSD coaches, athletes, and staff. In consultation with the Business Services office, cancelation or postponement of start times based on hourly forecasts may be required.

• Should there be a possibility of canceling or postponing start times based on hourly forecasts, site administration needs to consult with the Assistant Superintendent of Business Services and, if determined, inform visiting teams as well as hosting teams for away competitions of our policy and potential cancelations or postponements by 11AM the day of the competition.
