What Just Happened?
The National Weather Service (NWS) issued dust storm warnings for parts of Arizona on Sunday evening. Here’s the quick rundown:
- Phoenix area (Maricopa & Pinal Counties): Warning until 9:30 p.m. MST. A massive wall of dust stretched from Usery Mountain Park to Tempe to 7 miles north of Estrella Sailport, moving northwest at 35 mph.
- Tucson area (Pima County): Warning issued at 5:40 p.m. MST until 6:45 p.m. MST. Dust wall spotted from 13 miles north of Arivaca to near Three Points, moving west at 10 mph.
IMPORTANT: "PULL ASIDE, STAY ALIVE!"
The NWS urges all drivers: Do NOT drive into a dust storm. Pull over safely and wait it out.
What Is a Haboob? (And Why the Funny Name?)
A haboob (say huh-BOOB) is a giant dust storm that happens during Arizona’s monsoon season (June–September).
How It Forms (ELI5 Version)
- Thunderstorms build up over the desert.
- Cold air rushes down from the storm (a "downdraft").
- That cold air slams into the hot desert floor and spreads out in all directions.
- The rushing wind scoops up loose dust and sand, creating a massive wall of dust.
- This wall can stretch for miles and reach thousands of feet high!
Fun Fact: "Haboob" comes from an Arabic word meaning "big, blasting winds." Andrew Deemer, an NWS meteorologist and former linguist, confirms this translation.
How Long Does a Haboob Last?
| Phase | Typical Duration |
|---|---|
| Main dust wall passes | A few minutes |
| Full event (start to finish) | Up to 1 hour |
| Lingering dust & poor visibility | 1+ hours (especially if multiple storm outflows combine) |
Key factors: Wind speed, how dry/loose the soil is, and whether multiple storms merge.
What To Do If You’re Driving: "Pull Aside, Stay Alive"
The Arizona Department of Transportation (ADOT) has a clear, life-saving protocol. Follow these steps IMMEDIATELY:
Step-by-Step Safety Guide
- Check traffic around you and start slowing down right away.
- Do NOT wait until you can’t see to pull over.
- Exit the highway completely if possible.
- Never stop in a travel lane OR the emergency shoulder.
- Find a safe spot fully off the paved road.
- Turn OFF all lights (headlights, hazards, interior).
Why? Other drivers might follow your lights and crash into you. - Set your emergency brake and take your foot off the brake pedal.
- Stay buckled up inside your vehicle until the storm passes.
High-Profile Vehicles (trucks, RVs, buses): You’re at higher risk for tipping or being pushed. Slow down early and be extra cautious.

Summary
- Two dust storm warnings were active in Arizona on Aug 23, 2026 (Phoenix & Tucson areas).
- These storms are called haboobs—intense walls of dust formed by thunderstorm downdrafts.

- If driving: PULL ASIDE, STAY ALIVE. Get off the road, kill your lights, buckle up, and wait.
- Never drive into the dust. Visibility can drop to near zero in seconds.
FAQ
1. What exactly is the difference between a dust storm and a haboob?
They’re essentially the same thing! "Haboob" is the specific name for the intense, wall-like dust storms caused by thunderstorm outflows, common in Arizona and arid regions worldwide.
2. Why do I have to turn OFF my car lights when pulled over?
In near-zero visibility, drivers instinctively follow lights. If your lights are on, someone might think you’re the lane and rear-end you. Lights off = you’re invisible = you’re safer.
3. Can I just keep driving slowly with my hazards on?
NO. Visibility can drop to less than 1/4 mile instantly. You won’t see stopped cars, pedestrians, or the road edge. Pulling over is the only safe choice.
4. When is monsoon season in Arizona?
Officially June 15 – September 30. This is when haboobs are most frequent.
5. Where can I see real-time radar for these storms?
Check the NWS radar loops (linked on azcentral.com/weather) or your favorite weather app for "radar" or "storm tracking" views.
