Arizona Issues Extreme Heat Warning as Temperatures Near 115°F

The National Weather Service issued an Extreme Heat Warning for Arizona, covering the Phoenix metropolitan area and parts of California's Imperial Valley, effective from the evening of July 9 through the evening of July 10. Forecasts call for afternoon temperatures ranging from 111 °F to 115 °F, with overnight lows remaining near 90 °F, creating a prolonged period of dangerous heat.

Health officials warned that the conditions could trigger heat‑related illnesses such as cramps, exhaustion, and potentially fatal heatstroke. Recommendations include limiting outdoor activity to early morning or evening, staying hydrated, wearing lightweight clothing, and using cooling shelters where available. The Occupational Safety and Health Administration advised frequent rest breaks for outdoor workers in shaded or air‑conditioned areas.

While the extreme heat dominates the forecast, meteorologists noted that monsoonal moisture is expected to move into the state later in the week, offering a chance of showers and thunderstorms that could provide temporary relief.
