If your home or property flooded during the storm, we're sorry you're dealing with this. We know the cleanup can feel overwhelming, especially when you're not sure where to begin.

Here are five things to do:
1. Make sure it's safe. Don't enter a damaged building until authorities say it's safe. Stay away from standing water and electrical hazards.
2. Contact your insurance company. Report the damage as soon as possible.
3. Take pictures. Document the damage before cleaning up or making repairs.
4. Protect your health. Floodwater can contain harmful contaminants. Wear protective gear and avoid contact with the water.
5. Begin cleanup safely. Follow your insurer's guidance and get professional help when needed.

You don't have to figure everything out at once.
Please share this with someone who may need it.

The Rain Has Stopped. The Water Is Still Moving.

After an exceptionally wet weekend, Maricopa County is finally seeing sunshine. But flooding concerns aren’t over.

🌧️ Three-day rainfall totals:
* Phoenix Valley/lower deserts: 1–3 inches
* Northern/eastern foothills and mountains: 3–8 inches

All that rain is still moving through rivers, streams, washes and flood control structures across the County.

⚠️ Please continue to use caution:
🚗 Never drive through flooded roads or around barricades.
🌊 Stay out of flowing washes, rivers and channels. Even calm-looking water can hide strong currents and debris.
📱 Check road conditions before traveling. Some crossings may remain flooded even under clear skies.
❤️ If you’re dealing with flooding or cleanup, please take care of yourself and check on your neighbors when it’s safe to do so.

The forecast looks much quieter this week, with sunshine and temperatures in the 70s.
But remember: The sky has cleared. The water hasn’t.

Weather Responsibly.

11/02/2026

The rain may be over, but we're not out of the woods yet.
Washes, rivers and flood control channels can continue flowing long after the rain stops. Some roads may still be flooded and areas that are normally dry may still be dangerous.

As you head out today:
- Never drive through flooded roads or around barricades.
- Stay out of flowing washes, rivers and flooded basins.
- Keep children and pets away from the water.
- Check road conditions before leaving home.
Sunshine doesn't mean the flood risk is gone. Give the water time to recede and follow official updates.

Heavy Rain Continues Across Maricopa County. Flooding Concerns Are Increasing.

Since Saturday evening, much of Maricopa County has received 0.75"–1.50" of rain, with some northern and eastern areas picking up 2.00"–3.50" or more.
And we're not done yet.

More rain is expected throughout today, with stronger thunderstorms possible this afternoon and evening. Some areas could receive several additional inches of rain where storms repeatedly develop.

🌊 We're already seeing rising water levels in washes and channels, including Indian Bend Wash, Skunk Creek and the Arizona Canal Diversion Channel (ACDC).
With soils already saturated from Friday's storms, additional rainfall could lead to more runoff, flooded roads and dangerous low-water crossings.

⚠️ A Flood Watch remains in effect through 5 AM Monday.

Please take these precautions:
🚗 NEVER drive through flooded roads or around barricades. Turn around and find another route.
🌊 Stay out of flowing washes, channels and flooded areas.
📱 Check weather conditions and your route before traveling.

Remember, the rain may stop before the water does. Some washes and crossings could remain flooded into Monday morning.

Weather Responsibly.

November in Arizona is pretty hard to beat. 🌵

Cooler temperatures make it a great time to get outside, but they're also a reminder that our weather changes throughout the year.

Rain and flooding aren't limited to monsoon season. Fall and winter storms can also bring heavy rainfall and flowing washes to Maricopa County.

Enjoy the beautiful weather and stay weather aware!

11/01/2026

The rain keeps falling. And now the water is moving.

Since Saturday evening, Maricopa County has received:
Phoenix Valley/lower deserts: 0.50”–1.00”
Northern/eastern County: 1.00”–2.00”

And more rain is expected today!

We’re seeing runoff in Indian Bend Wash, ACDC, Skunk Creek and lower Cave Creek. SRP is also releasing water through the Salt River system.

Water over the road? STOP. TURN AROUND.

Never drive through flooded crossings or around barricades. Check conditions before traveling and stay out of flowing washes.

Be weird about the rainfall map. Be boring around floodwater.

Weather Responsibly.

11/01/2026

Water has to go somewhere and the washes are the place. Even Scatter Wash in northern Phoenix is crossing the roads. If you encounter a flooded road find another route.

🎃🌧️ Halloween Weather Update: Rain Arriving Earlier Than Expected

We have an important change to the weekend forecast.
After Friday’s heavy rainfall, another round of showers and thunderstorms is expected to move into Maricopa County by mid to late Saturday afternoon, potentially affecting trick-or-treating and other evening Halloween activities.

Here’s what you need to know:

🌧️ Friday’s Rainfall: Much of northern Maricopa County received 0.25–1.00 inches, with some locations recording 1.50–3.00 inches, including portions of the Scottsdale area.
🌧️ Saturday–Sunday: Another 1–3 inches or more is possible across the County as widespread rain continues through Sunday night.
🌊 Flooding Concerns: Some soils are already wet or saturated from Friday’s storms. Additional rainfall could lead to increased runoff, flowing washes and water ponding on roadways.

⚠️ Flood Watch: The National Weather Service has issued Flood Watches for much of Arizona from Saturday evening through Sunday night.

Planning Halloween activities?

Check the latest forecast before heading out. Be prepared to adjust plans if conditions change, and keep children away from flooded streets, washes and retention basins.
Remember, rain may stop falling before runoff stops moving.

Never drive through flooded roads or crossings.
Weather aware doesn’t mean weather worried. It means prepared.

Weather Responsibly.

🌧️ Heavy Rain and Strong Storms Expected Today Across Maricopa County

The first of two weather systems is bringing widespread rain and thunderstorms to Maricopa County today, with the greatest impacts around Metro Phoenix expected from late morning through the afternoon.

⚠️ Today's concerns include:

🌧️ Heavy downpours with rainfall rates of 1–2 inches or more per hour under stronger storms
💨 Damaging wind gusts near 60 mph
🧊 Large hail
🌊 Localized flooding, flowing washes and water ponding on roads

Rainfall totals could reach 0.50–1.25 inches across much of the County, with localized amounts of 2 inches or more possible.

What about Halloween? 🎃

Saturday afternoon and early evening currently look much quieter, which is good news for trick-or-treating.
However, another round of widespread rain is expected Saturday night through Sunday and potentially into early Monday.
Because Friday's rainfall may leave soils saturated, Sunday's prolonged rain could increase runoff and flooding concerns.

Before heading out:

🚗 Check road conditions and never drive through flooded roads.
📱 Keep weather alerts enabled and follow official forecasts.
🌊 Stay away from flowing washes and flooded crossings.

Weather aware doesn't mean weather worried. It means prepared.

Weather Responsibly.
