Phoenix, AZ – This week, Arizona is experiencing a mix of warm, dry weather and isolated storms in high terrain areas due to a dominant high-pressure system. However, a notable change is anticipated mid-week as a low-pressure system arrives, bringing breezier conditions, lower humidity, and a significant cooling trend expected by next weekend.
Current Weather Conditions and Storm Activity
On Sunday afternoon, much of Arizona saw mostly sunny skies with warm and muggy conditions, while isolated showers and thunderstorms occurred in the state’s higher elevations. These storms moved slowly eastward, leading to a Flash Flood Warning north and northeast of Wickenburg until 7 p.m., cautioning residents about potential flooding in normally dry washes and drainages.
- Valley areas, including Phoenix, experienced clear skies with nighttime lows around 85 degrees.
- Most other locations remained dry through the evening hours.
Upcoming Week: Heat Persists but Cooling Looms
Monday will continue to be mostly dry, with only isolated showers and storms primarily in mountainous regions. The Valley is forecasted to see highs near 103 degrees, maintaining the warm and sunny pattern of early week. However, the week overall looks much drier compared to the previous week.
By mid-week, a large low-pressure system is expected to move onto the West Coast, ushering in breezy to windy conditions across Arizona from Wednesday through Friday. This shift will bring relief through decreased humidity and a gradual drop in temperatures, dropping below the low 100s by weekend as reported.
Heat Safety: Essential Tips to Stay Protected
Considering ongoing warm conditions, heat safety remains a critical concern. The Scottsdale Fire Department has outlined key information on recognizing and responding to heat emergencies, including heat cramps, exhaustion, and heat stroke.
“If symptoms worsen, call 911 immediately,” the department advises, emphasizing the importance of cooling and hydration.
- Move affected individuals to shade or a cool area and cool their body with wet cloths.
- Sip cool water if alert; gently massage cramped muscles.
- Avoid giving anything by mouth if vomiting or unconscious.
Preventative measures include:
- Hydrating before, during, and after physical activities.
- Wearing lightweight, light-colored clothing and protecting the head.
- Hiking or exercising with company and informing others of your plans.
Preventing Heat Exhaustion and Heat Stroke
The Arizona Department of Health Services recommends several precautions to combat heat-related illnesses:
- Stay in air-conditioned environments whenever possible.
- Visit cooling centers and hydration stations.
- Limit outdoor activities during peak heat hours, typically mid-day.
- Monitor at-risk individuals at least twice daily.
- Drink adequate water before, during, and after outdoor exertion.
- Check the UV Index and heat risk maps for daily safety guidance.
Safety While Driving in Extreme Heat
The Arizona Department of Transportation (ADOT) provides critical advice to drivers navigating the state’s extreme heat:
- Wear sun protection such as sunscreen, wide-brimmed hats, and light-colored clothing.
- Keep the gas tank at least three-quarters full to avoid breakdowns in remote areas.
- Bring extra cold drinking water and use frozen bottles to help cool off in emergencies.
- Immediately call for help if your vehicle experiences issues, and run the air conditioning if possible.
- If overheated inside your vehicle, exit safely, seek shade away from traffic, and avoid walking barefoot on hot pavement.
- Regularly maintain your vehicle’s air conditioning, coolant, battery, and tire pressure to reduce risks.
Monsoon and Flood Safety Preparedness
Flash floods and severe storms remain concerns particularly in high terrain and valley areas. The American Red Cross suggests key safety tips in case of heavy rain or flooding:
- Never drive through flooded roadways—turn around and find another route.
- If caught in rising waters, evacuate to higher ground promptly.
- Stay updated with local alerts via radio or news channels.
- Prepare an emergency kit, know evacuation plans, and designate safe areas indoors to shelter during storms.
- Do not approach downed power lines and keep pets indoors during storms.
Captain Ashley Losch of the Glendale Fire Department emphasized, “Storms can come quickly, causing disruptions to water, power, and gas. Being prepared can save lives.”
Stay Vigilant and Prepared This Week in Arizona
As Arizona endures the transition from a hot, mostly dry spell to cooler, breezier conditions, residents are encouraged to stay informed and take proper precautions during heat waves and potential storms. Staying hydrated, being aware of heat emergency signs, and following safety protocols while driving or outdoors are essential for health and safety.
