Lightning Guidelines

  • The Turlock Unified School District (TUSD) has implemented a Lightning Advisory System to monitor data regarding lightning strikes and to notify site administrators of conditions that could affect activities for students and staff. The administration monitors reports by and other reporting stations each day to determine the forecast and real-time lightning strikes. The District employs a 5-level color system to advise students and staff of the forecast and current conditions as follows:
    • 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.
