The Heat Index flag conditions guidelines for physical activity.

The index is created from four variables: air temperature, humidity, radiant heat and air movement.

With this information, station weather observers determine the appropriate flag for the conditions.

The heat index system, developed for military training in the 1950s, has four flags: green, yellow, red and black.

A green flag (80-84.9 degrees) indicates Coaches should be extra observant of those who aren't acclimatized to the area.

A yellow flag (85-87.9 degrees) means athletes should hold off from strenuous exercise.

A red flag (88-89.9 degrees) signals a halt in activity for athletes who have not been acclimatized for three months and holds those who have been there long enough to six hours of activity a day.

Finally, a black flag (more than 90 degrees) indicates all nonessential activity should be stopped. All efforts should be made to reschedule any outdoor training during cooler periods of the day.

Every athlete & Coach should be concerned about dehydration.

Your body can lose two liters of sweat per hour training in hot weather.
Water is far more effective than air at cooling the body.

Dehydration can cause heat cramps, exhaustion and stroke. Death from heat stroke can occur at temperatures as low as 70 degrees. Drink plenty of water, no matter what the temperature is!
