The National Weather Service has issued an excessive heat warning for Gila, Graham, Greenlee, La Paz, Maricopa, Pima, Pinal, and Yuma Counties from 8/20/19 from 11 AM to 8/21/19 8 PM. The excessive heat warning is in effect for Mohave County from 8/20/19 from 11 AM to 8/22/19 8 PM.

Daytime highs are expected to be in the 108-116 degrees Fahrenheit range.

An Excessive Heat Warning 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 – 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. 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. Continue to monitor NWS forecasts, broadcast outlets, and local government for updates.

The Salvation Army welcomes pets at its emergency heat relief stations, but they must be leased. The interactive map can also be used to find the closest Valley Metro light rail, bus routes, and bus stops using the layers dropdown menu.

Printable PDFs of all partner sites and additional information and resources can be found on the Heat Relief Network webpage, including the client survey and the daily tracking log (found under “Materials for Partners”). Results from the survey will be used to inform how to improve the Heat Relief Network.

Heat Risk
Heat affects everyone differently. In order to better address heat risk and allow you to prepare for upcoming heat events, the NWS has developed the experimental HeatRisk forecast. The NWS HeatRisk forecast provides a quick view of heat risk potential over the upcoming seven days. The heat risk is portrayed in a numeric (0-4) and color (green / yellow / orange / red / magenta) scale which is similar in approach to the Air Quality Index (AQI) or the UV Index. In a similar way, it provides one value each day that indicates the approximate level of heat risk concern for any location, along with identifying the groups who are most at risk. This product is supplementary to the official NWS heat watch/warning/advisory program and is meant to provide continuously available heat risk guidance for those decision makers and heat sensitive populations who need to take actions at levels that may be below current NWS heat product levels.
