Forecasters warn of major river flooding at Pagosa Springs and dangerous conditions on roads. - Author: News Desk - Tags: US, Arizona, Colorado, Nevada, New Mexico, Utah A new storm is bringing a renewed flood threat to the Southwest as rain falls on ground already soaked by repeated autumn storms. Forecasts issued Saturday warned of dangerous runoff through Monday, Nov. 2, with the threat extending from Arizona into the Four Corners region and parts of southern Nevada. The immediate concern is not simply how much rain falls. Saturated soil leaves less room for additional water, increasing the amount that can flow into streets, washes, creeks and rivers. The [Associated Press](https://abcnews.com/US/wireStory/heavy-rains-expected-bring-flooding-risk-saturated-parts-137739514?ref=theamericanquorum.com) reported widespread flood watches across Arizona and portions of Utah, Colorado, New Mexico and Nevada, citing the National Weather Service. In southwestern Colorado, the Weather Service’s Saturday evening forecast raised a particularly serious concern: the San Juan River at Pagosa Springs was forecast to reach major flood stage. That was a forecast of conditions to come, rather than confirmation that the river had already reached that level. ## Why another round of rain matters The [Phoenix office](https://forecast.weather.gov/product.php?site=PSR&issuedby=PSR&product=AFD&format=CI&version=1&glossary=1&ref=theamericanquorum.com) described an atmospheric river feeding a prolonged period of widespread rain from Saturday night into early Monday. Forecasters expected unusually large amounts of moisture for late October and early November, with the more persistent rain capable of raising waterways even without an exceptional thunderstorm directly overhead. Its forecast called for roughly three-quarters of an inch to 2.5 inches in lower-elevation parts of Maricopa and Pinal counties, with higher amounts favored near foothills. Arizona’s higher terrain could receive 3 to 5 inches, locally more. Those are ranges across different locations, not a prediction that every neighborhood will receive the upper amount. The office also identified a possibility of isolated strong or severe thunderstorms Sunday, mainly east of the Colorado River, with damaging winds the principal concern. Flooding remained the central regional threat because steady rainfall could generate runoff from soil that was already saturated. ## Flooding has already trapped drivers Recent conditions show why officials are concerned about another storm. Phoenix-area motorists required rescue after Friday thunderstorms flooded roads. [KJZZ](https://www.kjzz.org/kjzz-news/2026-10-31/thunderstorms-and-rain-hit-the-valley-scottsdale-receives-nearly-3-inches-of-rain?ref=theamericanquorum.com) reported that Maricopa County Flood Control District measurements showed nearly 3 inches of rain at one location in Scottsdale, west of Gainey Ranch. The station also documented runoff at Vista del Camino Park and the Scottsdale greenbelt on Saturday. Those observations corroborate the broad concern in the official forecast: the next system is arriving before the effects of the previous one have disappeared. KJZZ interviewed a Weather Service meteorologist who distinguished the incoming widespread moisture plume from Friday’s rounds of thunderstorms. That distinction is important because a quieter-looking stretch of weather does not necessarily mean the next flood threat has passed. ## River danger in the Four Corners The Weather Service’s [Grand Junction](https://forecast.weather.gov/product.php?site=GJT&issuedby=GJT&product=AFD&format=CI&version=1&glossary=1&ref=theamericanquorum.com) office said Saturday night that flood watches continued for southeastern Utah and southwestern Colorado. Its forecast anticipated rain, embedded thunderstorms and higher-elevation snow, with saturated terrain increasing the risk of flash flooding, debris flows and river flooding. Several southwestern Colorado rivers were forecast to reach minor flood stage. The office identified the San Juan River at Pagosa Springs as a more severe threat and said a Particularly Dangerous Situation flood warning was in effect there. Residents should follow the specific warning and local emergency directions; the severity at one river location should not be generalized to every community under a broader watch. The same forecast warned that runoff could carry rocks, mud and debris onto roads, with particular concerns around steep terrain, burn scars, washes, slot canyons and arroyos. Mountain travel presents an additional complication: snow levels were expected to fall Sunday into Monday, potentially bringing snow to some passes during the Monday commute. ## Know which alert requires action A flood watch and a flood warning convey different levels of urgency. Under the Weather Service’s [alert definitions](https://www.weather.gov/safety/flood-watch-warning?ref=theamericanquorum.com), a watch means conditions favor flooding and people should be prepared. It does not mean flooding will occur everywhere within the watch area. A warning means flooding is imminent or happening and requires action. A flash flood warning carries particular urgency because water can rise within minutes to hours. The agency advises people in flood-prone areas to move immediately to higher ground. Flash flooding can also occur where rain is not falling at that moment, so the absence of a downpour at a particular crossing is not evidence that it is safe. ## Road decisions can be decisive The Weather Service’s [driving guidance](https://www.weather.gov/safety/flood-turn-around-dont-drown?ref=theamericanquorum.com) is unequivocal: do not drive or walk into floodwater, and never go around a barrier closing a flooded road. Water can hide a damaged or collapsed road surface. Drivers cannot reliably determine the depth, current or condition of the pavement by looking across a flooded crossing. For the coming storm, the practical priority is to check local warnings and road closures before traveling and to respond to emergency directions promptly. Forecast amounts and river crests can change as rain develops. The central risk remains clear: additional rain across already saturated watersheds can create dangerous conditions before residents or travelers encounter an obviously severe storm.
