The National Weather Service has issued its first excessive heat watch of the season. The area affected includes southern Arizona, including Fountain Hills, beginning today, Wednesday, June 8, at 10 a.m. and continuing through Monday, June 13, at 8 p.m.

The Weather Service is forecasting dangerously hot conditions with highs ranging from 108 to 114. Overnight lows are forecast for the low 80s.

An excessive heat watch means that a period of very hot temperatures, even by local standards, will occur. Actions should be taken to lessen the impact of the extreme heat.

Stay indoors and seek air-conditioned buildings. Drink water, more than usual, and avoid dehydrating alcoholic, sugary, or caffeinated drinks. Dress for the heat with lightweight and light-colored clothing. Eat small meals and eat more often. Monitor those with a higher vulnerability to heat, including small children. Check in on family, friends and neighbors, especially the elderly. If engaging in outdoor activity, take longer and more frequent breaks and avoid the hottest parts of the day.

Never leave kids or pets unattended in cars.

Public cooling shelters are available in some areas. Consult county officials for more details, which may include guidance for proper social distancing measures.

Recognize the signs and symptoms of heat-related illness. Early signs include thirst and muscle cramps. Heat exhaustion may include cool, moist, pale skin; headache; dizziness; weakness or exhaustion; nausea. The most serious illness is heat stroke, which may include vomiting; confusion; throbbing headache; decreased alertness or loss of consciousness; high body temperature (above 105F); hot, dry skin; rapid, weak pulse; rapid, shallow breathing; seizures.

Heat stroke can be deadly. Treat as an emergency and call 9 1 1.
