Flood Watches Persist Across Southwest States

Flood Watches Persist Across Southwest States

The Desert Southwest is experiencing significant flooding due to robust monsoonal moisture and a weak tropical system. Flood watches remain active in western and northern New Mexico, southeast Utah, and southwest Colorado. Heavy rainfall has led to flash flooding, with rainfall rates exceeding 1 to 2 inches per hour in some areas. In Arizona, Maricopa County saw water rescues, and parts of Phoenix received up to 3.9 inches of rain. The National Weather Service warns of flash flooding risks in wildfire burn scars, urban areas, and regions with saturated ground. A strong upper-level low is also contributing to widespread showers and thunderstorms across the region. Source time: Thu, 17 Sep 2026 16:00:00 GMT.

Flash Flooding Kills 3 in New Mexico Amid Southwest Threat

Flash flooding in New Mexico claimed the lives of three individuals early Wednesday near Newcomb, according to the Navajo Police Department. The victims, two adults and one juvenile, were swept away by floodwaters following intense rainfall that began Tuesday afternoon and continued intermittently until midnight. The region, along with parts of Arizona, Utah, and Colorado, remains under a significant flood threat as a surge of moisture fuels heavy rainfall. A rare Level 3 of 4 flood risk has been issued for areas including Phoenix and Tucson, marking the highest flood risk for Phoenix since 2022. Rainfall totals in some areas have exceeded 3 inches in just a few hours, leading to inundated roads, stranded vehicles, and water rescues. The ongoing Southwest monsoon, combined with a tropical disturbance from northern Mexico, is intensifying the rainfall.

Southwest Faces More Flash Flood Threat After Deadly Storms

Southwest Faces More Flash Flood Threat After Deadly Storms

Another round of monsoon thunderstorms is expected across the Southwest and Four Corners Thursday after intense flash flooding in New Mexico killed three people. The Weather Prediction Center has issued a Level 2 of 4 flash flood risk for parts of Arizona, Utah, Colorado and New Mexico, including Albuquerque. Western and central New Mexico could see the heaviest rain, while storms gradually shift east through Saturday. High hourly rain rates may trigger rapid runoff, mudslides and dangerous debris flows, even where rainfall is limited.

Arizona Monsoon Season Brings Heavy Rains and Flash Flood Threat to Southwest

Arizona Monsoon Season Brings Heavy Rains and Flash Flood Threat to Southwest

Arizona is currently experiencing its monsoon season, which typically runs from June 15 to September 30. This seasonal wind shift brings increased humidity, leading to thunderstorms and heavy rainfall across Arizona, New Mexico, and parts of Utah. A Level 2 out of 4 flash flood threat is in effect for these regions. Recent storms have already caused significant damage in areas like Tucson, Arizona, where strong winds and rain uprooted numerous trees, leading to widespread power outages. Residents are cleaning up from these events, with some describing the storms as the most intense they have witnessed. Arborists note that certain tree species, particularly non-native ones like eucalyptus with shallow roots, are more susceptible to being toppled during these monsoon microbursts. Native trees like mesquites and palo verdes generally have stronger root systems, though hybrid variations and watering practices can affect their resilience.

Southwest flood risk rises under heat dome conditions

Southwest flood risk rises under heat dome conditions

Tropical moisture is intensifying flood threats across the Southwest, particularly in Arizona and New Mexico, as a persistent heat dome locks in monsoon activity. According to FOX Weather, this atmospheric setup is amplifying rainfall potential and increasing the likelihood of flash flooding in vulnerable areas. Arizona State University Professor Randall Cerveny highlighted the interplay between the heat dome and monsoon dynamics, which are creating conditions for prolonged heavy rainfall. The heat dome, a high-pressure system, traps warm air and moisture, fueling the monsoon and exacerbating flood risks. This development underscores the importance of monitoring weather patterns closely in the coming days.
