  • Excessive Heat Warning: Issued when an excessive heat event is expected to occur within the next 12 hours.

  • Heat Advisory: Issued when the heat index is expected to reach 100°F (37.8°C) or higher for at least two consecutive hours.

These alerts are designed to inform the public of impending heat events and to encourage appropriate precautions.
