    Does anyone know what is on that board/sign in Barney Square? I see them go over to it from time to time and they appear to be writing perhaps? Just a curious mom...

    Weather- heat index measurements and any restrictions on activities based on the temperature.

    I was looking at photos albums of Anthony, the guy that is taking this year's Indoc photos, from last year and one of his photos from last year show the board and what is on it. It has Wet and degree, Dry and degree, WBGTo and degree and RH and degree. At the top of the board, it also has the color of the flag.
    I was told that there are three flags, Green, Orange and Black. They didn't explain Orange but Black means that it is too hot or dangerous to go outside and do anything. I was also told that the DI's are not going to make the squad do anything they don't want to do outside. Haha.

    I hope this helps. Now what WBGTo and RH means? I don't know. If someone can explain that, I would appreciate it.

    The Wet Bulb Globe Temperature is a calculation that takes into account temperature, humidity, wind speed and radian heat. It factors all the conditions into one value, a heat category.

    The heat categories 1 through 5 are indicated with flag conditions. The flag conditions or heat category determine recommended work-rest cycles.

    Flag Conditions

    White flag (78 to 81.9) - Normal activity for people accustomed to climate; extremely intense physical exertion may cause heat stroke for people who aren't. No limits on light and moderate work; heavy work 40 minutes, rest 20 minutes.

    Green flag (82 to 84.9) - Normal activity for those accustomed to the climate; people who aren't should use discretion in planning intense physical activity. No limit on light work; moderate work 50 minutes, rest 10; heavy work 30 minutes, rest 30.

    Yellow flag (85 to 87.9) - People accustomed to the climate should use caution in planning intense physical activity; those who aren't should curtail strenuous activities. No limit on light work; moderate work 40 minutes, rest 20; heavy work 30 minutes, rest 30.

    Red flag (88 to 89.9) - Those accustomed to the climate should curtail strenuous exercise and limit conditioning for periods not exceeding six hours; people who aren't should terminate all physical conditioning. No limit on light work; moderate work 30 minutes, rest 30; heavy work 20 minutes, rest 50.

    Black flag (90 and above) - Light work 50 minutes, rest 10; moderate work 20 minutes, rest 40; heavy work 10 minutes, rest 50.
