Safety Considerations
Heat Advisory:
Harford County cancellation policy states that if the temperature/humidity index reaches a level above 85, which is the temperature plus the humidity equals 175 or more ( i.e. 90 degrees plus 85% humidity), outside activities should be cancelled. In addition, if the temperature reaches 100 degrees, outside activities should be cancelled.
Final decisions are at the discretion of the program chairperson/director, depending on the activity and time of day.
The Heat Index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature. To find the Heat Index temperature, look at the Heat Index Chart above or check our Heat Index Calculator. As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat index--how hot it feels--is 121°F. The red area without numbers indicates extreme danger. The National Weather Service will initiate alert procedures when the Heat Index is expected to exceed 105°-110°F (depending on local climate) for at least 2 consecutive days.
