• Ferguson-Florissant School District Weather Guidelines for Extreme Heat

    Administrators and teachers will make adjustments in school activities to insure the safety and comfort of our
    children when periods of extreme heat develop. In general, it is the District’s policy to remain open for
    a full day of school once classes begin each day. Extreme heat sometimes create conditions changing
    the normal routines of the school day such as recess or after-school activities like football practice.

     

    Summer:

    The National Weather Service and the Missouri Department of Health issue warnings of extreme heat events
    during the summer months. Administrators and teachers will adjust student activities during these periods to
    ensure the health and safety of our students.

    The National Weather Service’s Heat Advisory/Warning is based on a term called the Heat Index and the length
    of time the extreme heat lasts. The Heat Index is a complex formula that simulates what it “feels like” to
    humans given a certain temperature and relative humidity.
     
    • Heat Advisory is issued when the heat index is expected to be at least 105 degrees for 3 hours or more
      with a minimum heat index of 80 degrees during a 24-hour period.
    • Heat warning is issued when the heat index is expected to be at least 115 degrees for 3 hours or more
      with a minimum heat index of 80 degrees during a 24-hour period, or when the heat index is to be in the
      105 degrees to 114 degrees (or higher) for at least 3 days.

    The Missouri Department of Health also issues Advisories/Warnings for extreme heat events. They are called:

    • Hot Weather Health Advisory or a Hot Weather Health Warning.
    • Hot Weather Health Advisory is issued when the heat index is 105 degrees or greater.
    • Hot Weather Health Warning is issued two days after a Hot Weather Health Advisory continues and if
      the forecast calls for the heat to continue for 48 more hours.

    Precautions To Take:

    • On any given day, when the heat index is 105 degrees or higher, all outdoor athletics/activities should be
      postponed or moved inside to air conditioned facilities.
    • When the heat index is 95 degrees – 104 degrees, athletics/activities may take place outside with the
      following conditions: hydration, breaks, and rest every 20 minutes. In addition, an early stop time may
      be given by the Athletic Director for athletic practices and after-school activities. The Athletic Director
      will communicate with coaches regarding these precautions.
