Arizona weather forecast: Monsoon, dust storm roll into the Valley
9 p.m. Weather Forecast - 8/25/25
FOX 10's Cory McCloskey has the latest on Monday night's monsoon storm.
PHOENIX - Much of Arizona saw a monsoon storm roll in, and in the Valley, we saw a massive dust storm cover roads as rush-hour traffic weaved through the city.
Today:
Showers and thunderstorms hit the Valley starting around 5 p.m. Scattered rain will last through the late evening, before we will dry out overnight.
Flights were delayed at Phoenix's Sky Harbor Airport due to the storm causing a ground stop. As of 6:45 p.m., the ground stop had been lifted.
Monsoon dust storm blankets Phoenix area
We're taking a look at our SkyFOX footage over the Valley on Monday night as a monsoon dust storm blanketed homes, roads, cars and highways.
Tuesday:
The rain from the Valley will continue north through the high country through Tuesday morning. Temperatures will fall into the low 80s in the Valley by Tuesday morning.
The rain chances are a bit lower on Tuesday, and we will see a drier and sunnier day in the Valley, but isolated showers and storms will become possible during the afternoon and evening.
The rest of AZ will see isolated showers and storms as well. Monday and Tuesday storms will bring the chance for damaging wind gusts, blowing dust, heavy downpours, flooding and lightning.
A flood watch remains in effect for the Kaibab Plateau until Tuesday evening, for the threat of flash flooding around the White Sage and Dragon Bravo burn scars, along with canyons, creeks and swimming holes.
Later this Week:
Temperatures will stay around 99 degrees on Tuesday, before climbing to around 101 degrees on Wednesday.
The second half of the week will be drier, statewide. The humidity will be less noticeable by late mid-week, as drier air moves in.

Preventing heat exhaustion/heat stroke
The Arizona Department of Health Services stated the following precautions can be taken to prevent heat exhaustion or heat stroke:

Driving in extreme temperatures
The Arizona Department of Transportation’s tips for driving in extreme temperatures include:
Have sun protection: In addition to an umbrella, take sunscreen and a wide-brimmed hat and wear loose-fitting, light-colored cotton clothing.
Fuel up: Keep your tank at three-quarters full. Running out of gas, especially in a remote location, is dangerous in extreme heat.
Hydrate: Take a cooler to keep extra drinking water cold, and consider adding several frozen bottles of water to use for cooling off or to thaw and drink if needed. Make sure everyone, including pets, stays hydrated.
Get help: If your vehicle breaks down in extreme heat, call for assistance right away to reduce wait time, and run the AC. If the AC isn’t working, roll down all windows.
Wait safely: If the temperature inside your vehicle becomes too hot, everyone, including pets, should exit carefully and seek out or create a shaded area as far away from the travel lanes as possible. Be careful walking on the road surface, which can be hot enough to burn skin. Keep your shoes on and try to keep your pets’ paws off the pavement. If you are stopped along the highway, raise the front hood and turn on hazard lights. Please keep in mind that parking in tall brush can start a fire.
Check your vehicle: You can help avoid breakdowns and blowouts by making sure your vehicle is in good operating condition. Check your air conditioner and coolant levels, top off any vital engine fluids and make sure your battery is up to par. Check your tire pressure, as the combination of under inflated tires and hot pavement can lead to a blowout.

Rain/flood safety tips
The American Red Cross' tips for heavy rain situations and flood safety:
- Turn around don’t drown! If you must drive and you encounter a flooded roadway, turn around and go another way.
- If you are caught on a flooded road and waters are rising rapidly around you, get out of the car quickly and move to higher ground.
- Tune in to your local radio, NOAA radio, or news channels for the latest updates.
- If your neighborhood is prone to flooding, be prepared to evacuate quickly.
- Follow evacuation orders and do not attempt to return until officials say it is safe.
- If power lines are down, do not step in puddles or standing water.
- If power is out, use a flashlight. Do not use any open flame as alternate lighting.
Preparing for a severe thunderstormÂ
The American Red Cross' tips for preparing for a severe thunderstorm:
- Put together an emergency kit.
- Know your community’s evacuation plan.
- Create a household disaster plan and practice it.
- Purchase a battery-powered or hand-crank radio
- Discuss thunderstorm safety with members of your household. Be aware that a thunderstorm could produce flooding.
- Pick a safe place in your home for household members to gather during a thunderstorm. This should be a place where there are no windows, skylights, or glass doors, which could be broken by strong winds or hail and cause damage or injury.
Be prepared and stay safe during the monsoon
"Most Valley residents know how quickly and furiously storms can move in and out, bringing strong winds, dust, rain, and flash flooding. These storms can cause interruptions in services, such as water, power, and gas," stated Captain Ashley Losch of the Glendale Fire Department.
GFD reminds residents of ways they can be prepared and stay safe:
- Have flashlights with extra batteries on hand.
- Have food that can be prepared without the need for cooking or refrigeration.
- Have at least one gallon of clean water for each person in the household.
- Have backup power for anyone requiring power for a medical device.
- Have backup power for cell phones that do not require charging.
- Have a first aid kit ready and accessible.
- Never drive into areas with flowing water; it takes less than 10 inches to wash a car away.
- Avoid flooded areas, such as washes.
- If waters are rising, seek higher ground.
- Do not approach downed power lines, the ground can be energized for up to 200 feet.
- Keep pets indoors during storms.
