Heat — Wet Bulb Globe Temperature, Region Category 3

Tennessee is in Region Category 3 of the U.S. Soccer regional heat map. WBGT is estimated from air temperature and humidity using the same approximation the U.S. Soccer lookup table is built from. That approximation is stated to be valid for full sunshine, so we scale it by the measured sunlight at the hour in question: in full sun the number is exactly the U.S. Soccer chart value, and after sunset it falls to the shade reading the chart cannot express. Both figures are shown in the hourly table.

U.S. Soccer heat alert levels for Region Category 3
Alert level	Threshold	Conditions	Required action
BLACK	>92.0 °F	Extreme Conditions	No outdoor training. Delay training until cooler, or cancel training.
RED	90.1-91.9 °F	High Risk for Heat Related Illness	Maximum of 1 hour of training with 4 separate 4-minute breaks within the hour. No additional conditioning allowed.
ORANGE	87.1-90.0 °F	Moderate Risk for Heat Related Illness	Maximum of 2 hours of training with 4 separate 4-minute breaks each hour, OR a 10-minute break every 30 minutes of training.
YELLOW	82.2-87.0 °F	Less than Ideal Conditions	3 separate 4-minute breaks each hour, OR a 12-minute break every 40 minutes of training.
GREEN	<82.1 °F	Good Conditions	Normal activities. 3 separate 3-minute breaks each hour of training, OR a 10-minute break every 40 minutes.

One national table; there are no regional categories for cold.

U.S. Soccer cold weather alert levels
Alert level	Threshold	Conditions	Required action
BLACK	<0 °F	Extreme Conditions	Cancel, or attempt to move activities indoors. Frostbite could occur.
RED	1-15 °F	High Risk for Cold Related Illness	Consider modifying activity to limit exposure and allow for more frequent chances to rewarm.
ORANGE	16-24 °F	Moderate Risk for Cold Related Illness	Provide additional protective clothing, cover as much exposed skin as practical, and provide opportunities and facilities for rewarming.
YELLOW	25-30 °F	Less than Ideal Conditions	Be aware of the potential for cold injury and notify appropriate personnel of the potential.
GREEN	>30 °F	Good Conditions	Normal activities.

In wet conditions these risks are accelerated. Use additional caution to recognise potential cold injuries.

Thunder and lightning

If thunder is heard or lightning is seen, go to your car IMMEDIATELY and stay there until you are notified that it is safe to return. If games are cancelled, that will be communicated through approved club communications.

Lightning is not part of the U.S. Soccer heat or cold tables. Do not wait for this page: a cancellation reaches you through approved club communications.
