Harford County does have a weather related cancellation procedure that in simple terms states that if the Temperature/Humidity Index reaches a level above 85 which in simplified math is: if the temperature plus the humidity equal 175 or more ( i.e. 90 degrees plus 85% humidity), practices should be cancelled. In addition, if the temperature reaches 100 degrees, practices should be cancelled. I leave these decisions in the Chairpeople hands as we all have to guess what it will be like at 6 PM as opposed to 2 or 3 in the afternoon. In any event, please advise your coaches to show extreme caution with the kids(light clothing, plenty of fluids, plenty of breaks, etc).
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.
