Four Corners Floods: 9 Flash Flood Preparedness Lessons
Updated: 3 days ago
Between Wednesday night, Oct. 21, and Friday, Oct. 23, 2026, a slow, soaking storm system turned dry washes and mountain rivers in the Four Corners region into floods. Utah residents waited on rooftops. Two adults and two dogs waited for a helicopter hoist after their RV was swept down a Colorado river. In New Mexico, deputies pulled people out of homes with 3 to 4 feet of water inside. Then volunteers, the Red Cross, the National Guard, and neighbors stepped in. Here is what happened, what officials are saying, and the flash flood preparedness lessons every family can use, whether you live in the desert Southwest or anywhere it rains.
What Happened: The Four Corners Floods at a Glance
The Four Corners is where Utah, Colorado, New Mexico, and Arizona meet. According to The Guardian's report (with wire agencies), the flooding followed about two months of heavy rain that ended a summer of drought. A National Weather Service meteorologist in Grand Junction told reporters the ground was saturated: "This is the third or fourth round of this kind of moisture we've seen in as many weeks."
Hurricane, Utah: a flood wave down Gould Wash
On Thursday morning, Oct. 22, 1 to 2 inches of rain fell over the headwaters of Gould Wash and sent what the National Weather Service called a "large flood wave" through the city of Hurricane in Washington County, KSL reported. The city declared a local emergency. Initial assessments counted about 80 homes and 50 RVs at the Willow Wind RV Park affected, plus damage to bridges, culverts, roads, and electrical boxes. Video showed a shipping container drifting down a street.
The part every prepper should read twice: residents told KUTV the evacuation text came only minutes, or seconds, before water reached them. One renter said she had no idea about the flood risk until water was pouring into her home, and she waited on her roof until police escorted her out. Washington County's emergency manager said the flood "was just so fast there wasn't a good way to predict that." The same neighborhood had flooded in August.
Pagosa Springs, Colorado: the San Juan River near a 1911 record
In southwest Colorado, the Archuleta County Sheriff's Office ordered mandatory evacuations on Oct. 22 for low-lying areas along the San Juan, Rio Blanco, Navajo, and Piedra rivers, per The Pagosa Springs Sun. The Durango Herald reported the San Juan River at Pagosa Springs crested at 15.02 feet at 4:45 a.m. Friday. The record is 17.8 feet, set in 1911.
The sheriff told 9NEWS there was "wide scale catastrophic destruction." He described an occupied RV swept about 100 yards downstream around 2:30 a.m. with two adults and two dogs inside, waiting for a National Guard hoist. An elderly couple who were hypothermic was also carried out across a flooded road by swift-water crews.
Farmington, New Mexico: about 600 households told to leave
In San Juan County, New Mexico, crews used Guard boats, helicopters, and amphibious vehicles to reach people, and about 600 households in Farmington were told to evacuate, The Guardian reported. A county spokesperson said: "We're picking people off of roofs and pulling people out of houses that have 3 or 4ft of water in them." A National Weather Service flood warning noted the San Juan River's flooding extent in New Mexico had not been seen since before Navajo Dam was completed in 1962.
Arizona had its own hit: the Center for Disaster Philanthropy noted the strongest tornado in the state in 15 years earlier that week.
The Good News: How Communities Showed Up
This story is not only about loss. The response has been fast and generous, and it shows what a prepared community looks like.
Rescues from the air and water. Colorado's State Emergency Operations Center update lists about 20 Colorado National Guard members running a hoist-equipped UH-60 Black Hawk and a LUH-72 Lakota for aerial search and rescue, plus nearly 80 more personnel and 30 tactical vehicles for ground search and rescue.
Shelter and food. The American Red Cross opened shelters in three Colorado counties, and The Salvation Army ran mobile feeding for shelter residents and first responders, according to the same update. In Hurricane, Utah, a local church stake center opened as an emergency shelter.
Free cleanup help. Crisis Cleanup set up a hotline (970-283-7325) so residents can ask for free volunteer help, and the Red Cross delivered nearly 300 cleanup kits, with 400-plus more staged with partners.
Lodging. 211 Colorado and Airbnb are offering up to 28 nights of free lodging to primary residents under mandatory evacuation and to deployed responders.
If you want to help, the most useful thing is usually money to established relief groups working on the ground, not shipping donated goods that responders then have to sort.
What's Confirmed and What Isn't
Confirmed by officials or multiple outlets: evacuations in all three states, the Pagosa Springs crest of 15.02 feet, about 80 homes and 50 RVs affected in Hurricane, about 600 Farmington households told to evacuate, and Colorado's disaster emergency declaration. Not yet known: the full damage totals and cost. Colorado said on Oct. 26 that damage assessments were expected to begin this week, and Hurricane officials said the full extent of the damage was still being assessed. We'll avoid guessing at numbers that haven't been released.
Flash Flood Preparedness: 9 Lessons From This Week
The pattern in these reports is the same one emergency managers warn about every year: water moved faster than warnings, people were caught in RVs and low-lying homes, and vehicles became traps. Here's how to turn that into a plan.
1. Assume your phone alert may come late, or not at all
Wireless Emergency Alerts depend on cell towers. Washington County's emergency manager told KUTV that if you leave the area, "you do not get any follow-up information," and he urged residents to also register their cell phone and email with the county's reverse-911 system. Do the same where you live: search "[your county] emergency alerts sign up" today. A new federal law signed last week, the Mystic Alerts Act, sets up a path for sending alerts by satellite when towers fail, but KSAT reports the FCC has a year and a half to write the rule, and it would not take effect for at least three years after that. Don't wait on it. Keep two or more ways to get warnings, including a NOAA Weather Radio or local broadcast radio.
2. Know whether you live near a wash, creek, or river
In Hurricane, the renter "had no idea of the flood risk." Look up your address on FEMA's Flood Map Service Center, and walk your neighborhood. If you're near a dry wash, the bottom of a canyon, or a river corridor, you are in a flash flood zone no matter what the sky looks like over your house. Rain miles upstream is what sent the wave down Gould Wash.
3. Learn the difference between a watch and a warning
A flood watch means conditions could produce flooding, so get ready. A flash flood warning means flooding is happening or about to, so move to higher ground now. Ready.gov's flood guidance says: evacuate if told, move to higher ground or a higher floor, and stay off bridges over fast-moving water.
4. Never drive or walk into floodwater
The National Weather Service, citing the CDC, says more than half of flood-related drownings happen when a vehicle is driven into hazardous water. Per the NWS flood safety page, 6 inches of fast-moving water can knock over an adult, 12 inches of rushing water can carry away most cars, and 2 feet can carry away SUVs and trucks. The road under that water may also be gone; Navajo Police warned that Paiute Farms Road near Oljato, on the Utah-Arizona line, had collapsed during this event, FOX 13 reported. Turn around and find another route.
5. RVs and campers need an exit plan
Two of the most dramatic rescues this week involved RVs, one park evacuated in Utah and one RV swept downstream in Colorado. If you live in or travel by RV, know your campground's high ground, keep keys and shoes by the door, and leave at the watch stage, not the warning stage. Don't sleep in a riverside site when a flood watch is posted.
6. Pack a grab-and-go bag that stays dry
When you have minutes, you won't pack. Keep a bag by the door with medications, copies of ID and insurance papers, phone chargers, cash, a change of clothes, water, snacks, and a light. Ready.gov specifically says to keep documents in a waterproof container. A fully waterproof pack like the Rothco Waveguard Waterproof Backpack keeps gear dry if you have to slog through rain or splash across a parking lot to your car. Gallon zip bags inside any pack are a cheap backup.
7. Plan for a dark, wet night
The Pagosa Springs crest came at 4:45 a.m., and the sheriff noted "it's always harder to deal with stuff at night." Power boxes were damaged in Hurricane. Keep a hands-free light in your go-bag, such as the Rothco Cree LED Headlamp, so you can carry a child, a pet, or a bag while you move. Add real rain gear: a waterproof shell like the Rothco Shadow Ops Waterproof Rain Jacket keeps you drier while you load the car or wait at a shelter. Being cold and wet is how people get hypothermic, as that elderly couple in Colorado did. Our cold-weather layering guide explains how to stay warm with layers.
8. Treat every tap and well as suspect after a flood
Floodwater can carry sewage, livestock waste, and chemicals. The CDC says to follow local advisories and use bottled, boiled, or treated water. Boiling is the best way to kill germs: a rolling boil for 1 minute, or 3 minutes above 6,500 feet. That altitude note matters in the Four Corners, since Pagosa Springs sits above 7,000 feet. Chemical disinfectants such as Potable Aqua Water Purification Tablets are a good backup when you can't boil, but the CDC notes they don't work as well as boiling against some parasites, like Cryptosporidium. And no boiling or tablet makes water safe if it contains fuel or toxic chemicals. If it smells like fuel or chemicals, don't use it. For more on choosing filters, see How to Find the Best Water Filter for Emergencies.
9. Clean up safely and check your insurance now
Ready.gov advises returning home only when authorities say it's safe, wearing heavy gloves, boots, and protective clothing for cleanup, staying away from wet electrical equipment, and running generators only outdoors. Also: standard homeowners policies do not cover flood damage, and an NFIP flood policy typically takes up to 30 days to start, so buy it well before the next storm.
Your 10-Minute Flash Flood Checklist
Sign up for your county's emergency alerts with your cell number and email.
Look up your address on FEMA's flood map and note nearby washes, creeks, and rivers.
Pick two evacuation routes that avoid low-water crossings.
Put a go-bag by the door with meds, documents in a waterproof bag, cash, water, food, a headlamp, and rain gear.
Keep a radio for warnings that don't rely on cell towers.
Plan for pets: leashes, carriers, and food in the go-bag.
Store water and a way to treat it.
Call your insurance agent about flood coverage.
When to Call 911
Call 911 if someone is trapped by rising water, has been swept into water, is injured, or shows signs of hypothermia, such as confusion, slurred speech, or very drowsy behavior. If you're trapped in a building, Ready.gov says to go to the highest level and only climb onto the roof if necessary, then signal for help. Don't climb into a closed attic, where you could be trapped. If your car is caught in fast water, stay inside, and get on the roof if water rises inside the car.

FAQ
What is flash flood preparedness?
It's knowing your local flood risk, having more than one way to get warnings, a go-bag that's ready to grab, an evacuation route that avoids low spots, and a plan for safe water and cleanup afterward. Flash floods can arrive within minutes, so the planning has to happen before the rain.
How much water does it take to sweep a car away?
According to the National Weather Service, about 12 inches of rushing water can carry away most cars, and 2 feet can carry away SUVs and trucks. Six inches of fast-moving water can knock an adult off their feet.
Can you get a flash flood when it isn't raining where you are?
Yes. In Hurricane, Utah, rain over the headwaters of Gould Wash sent a flood wave downstream into town. Watch forecasts for the whole watershed, not just your street.
Is tap water safe to drink after a flood?
Not until local officials say so. Follow boil-water advisories, use bottled or treated water, and never use water that may contain fuel or chemicals. Boil for 1 minute, or 3 minutes above 6,500 feet.
How can I help the Four Corners flood victims?
Give to established relief organizations working in the area, such as the American Red Cross or The Salvation Army, and residents in southwest Colorado can request free cleanup help from Crisis Cleanup at 970-283-7325.
