Central Arizona Floods: How to Check Warnings and Stay Safe

Central Arizona flood snapshot: At 10:03 p.m. Mountain Standard Time (MST, UTC−07:00) on Sunday, November 1, 2026 (05:03 UTC on Monday, November 2), official pages showed active flood warnings and flood-related highway closures in parts of central and northern Arizona. The National Weather Service (NWS) had a Flood Warning for Oak Creek in Coconino and Yavapai counties through noon MST Monday, and a Flash Flood Warning near the Sand Stone burn scar in Maricopa County through midnight MST. AZ 511’s 8:13 p.m. MST update listed several closed highways, including State Route 89A near Sedona. These are time-stamped reports, not a live status feed; check the current alert and road pages before traveling or deciding whether to evacuate.

Warnings and closures reported at the time checked

Read the latest NWS Flood Warning statements, NWS Flash Flood Warning statements, and AZ 511 alerts. The NWS reports that water levels and warning areas can change. AZ 511’s closure list had no estimated reopening times in the update reviewed. A closure may be lifted or extended later, so confirm the specific road again immediately before departure.

How to check a Central Arizona flood warning

1. Search the exact place. Open the NWS Active Alerts map and check your city, ZIP code, county, or the road and wash near you. Central Arizona spans more than one NWS forecast area. For Phoenix and much of Maricopa County, use the NWS Phoenix office; for Sedona, Flagstaff, and nearby northern and western areas, check the NWS Flagstaff office. A countywide headline may not describe every neighborhood equally.
2. Read the alert itself, including its map and expiration. Check the affected zone, rivers or washes named, issue time, expiration time, and any “updated” or “until further notice” wording. A warning can be extended, replaced, or canceled. Arizona generally uses MST (UTC−07:00) year-round; most of the state does not switch to daylight time. The Navajo Nation is an exception, so follow the time zone named by the issuing office when checking a location there. NIST summarizes the U.S. daylight saving time rules and Arizona exception.
3. Check local emergency instructions. Review your city and county emergency-management channels for evacuation zones, shelter locations, sandbag information, and local closures. The Coconino County Alert Center posted a GO evacuation order for Sedona Zones 8, 9, and 10 at 10:00 a.m. MST on November 1 and named Sedona Red Rock High School as the destination. That dated post may be superseded; residents should verify the latest official notice and follow any current evacuation direction immediately.
4. Check the route, not only the weather. Use AZ 511’s map and alerts for state-highway closures and delays. The Arizona Department of Transportation says its travel-information system also provides highway cameras, conditions, and road restrictions; call 511 only when you are safely stopped or use a passenger. For Maricopa County rainfall and drainage information, see the Maricopa County Flood Control District.

What a watch, warning, and advisory mean

A Flood Watch means conditions are favorable for flooding, but flooding is not certain. Treat it as preparation time: turn on official alerts, charge phones, gather medication and essential documents, identify a route to higher ground, and avoid planning a drive through a flood-prone area. The NWS explains the distinction in its Flood Watch versus Warning guide.

A Flood Warning means flooding is occurring or imminent; a Flash Flood Warning means flash flooding is in progress, imminent, or highly likely. Take action immediately: move to higher ground, leave a threatened area when officials direct you to evacuate, and do not wait for water to reach your home or road. An Advisory usually signals a less severe flood hazard than a warning, but it does not make a road, wash, or low-water crossing safe. The NWS definitions are available in its flood product guide.

Do not assume a phone will deliver every alert. Wireless Emergency Alerts are available for certain high-impact warnings, but the NWS says they may not include all details. Check NWS and local emergency sources directly, especially if you are in a watch area or near a creek or wash. See the NWS information on Wireless Emergency Alerts.

Flash-flood safety while driving or outdoors

• Never drive through floodwater or around a barricade. Water can conceal a washed-out road, debris, or a deeper channel than it appears to be. Turn around and choose a route that official road information shows is open. Do not stop in or next to a wash to take photos.
• Move uphill on foot; do not try to drive out of a flash-flood area. The NWS advises people to go to higher ground because rain upstream can send water into a place where it is not raining. Stay away from washes, creek banks, drainage channels, underpasses, and low-water crossings. A normally dry channel can fill quickly.
• If your vehicle stalls in rising water, get to safety. Call 911 if you are trapped or in immediate danger. If you can exit without entering stronger or deeper moving water, leave the vehicle and move to higher ground. Do not re-enter a flooded roadway to retrieve belongings.
• If you are camping or hiking, leave low ground early. Move away from creek beds and narrow canyons when a warning is issued or water begins rising. Do not wait for rain at your exact location; heavy rain elsewhere in the drainage can cause a sudden rise downstream.
• At home, follow evacuation orders and avoid electrical hazards. Move to an upper floor or higher ground if water is entering. Do not enter a flooded basement or room where water may cover outlets, cords, or electrical equipment. If trapped, move to the highest safe point and call 911.

The NWS lists these steps in its flood safety guidance. Maricopa County also warns that parks, basins, and channels can become dangerous when they carry floodwater; its Flood Control District page provides local rainfall information and preparedness resources.

Verified information, local variation, and unknowns

Verified in the official updates checked: the NWS had the Oak Creek and Sand Stone burn-scar alerts described above, and AZ 511 listed flooding-related highway closures with a last-update time of 8:13 p.m. MST on November 1. Coconino County’s Alert Center showed the dated Sedona evacuation order for Zones 8–10.

Location-dependent: an alert may cover a specific creek, burn scar, drainage basin, or evacuation zone rather than all of Central Arizona. Conditions can differ across town and change between updates. Check your address and route against the live warning map and current local instructions.

Not established by these pages: the exact water depth on an unlisted road, whether a home is safe to enter, or whether a closure or evacuation order remains unchanged after the timestamp shown. Do not infer safety from a dry-looking road or an expired alert on an old screenshot. Confirm with current officials; call 911 for an immediate threat to life.

Bottom line: check NWS alerts for your exact location, local emergency orders for evacuation zones, and AZ 511 for road closures. If water is moving across a road or an official warning tells you to act, go to higher ground and follow the order. Never walk or drive into floodwater.
