ALBUQUERQUE, NM — New Mexico is heading into a wetter stretch as the summer monsoon winds down, with daily shower and storm chances expected across nearly the entire state this week. Forecasters say the increase in moisture will raise the threat of flash flooding in several places, including burn scars around Ruidoso.
The shift comes after a dry summer that left Albuquerque with its driest and hottest season on record. Even with more storms on the way, meteorologists warn the state does not have enough time left in the monsoon season for rainfall to make up the difference. The National Weather Service is preparing to mark the monsoon’s end on Sept. 30.
Gallup streets flooded Monday as storm water surged through town
The risk is not theoretical. Several streets in Gallup flooded Monday afternoon, and videos shared on social media showed cars moving through water that rose higher than their tires. The flooding served as an early example of how quickly storms can create dangerous conditions, especially when rain falls hard over a short period.
Statewide, the National Weather Service expects a sharp rise in storm activity through midweek. The atmosphere will hold near-record amounts of moisture through Thursday, a setup that increases the odds of heavy rainfall once storms form. That does not guarantee flooding everywhere, but it does make intense downpours more likely in the strongest cells and in spots that get hit repeatedly.
Forecasters say drought relief will be limited despite the rain
At a Monday briefing, senior service hydrologist Andrew Mangham of the National Weather Service’s Albuquerque office said the incoming moisture should help plants, wildlife and fire conditions, but not enough to erase the state’s drought problems. He said the rain may reduce fire risk and give ecosystems a little more time, yet it will not refill reservoirs or eliminate drought statewide.
Mangham also said he is optimistic that some of the most extreme drought areas on the U.S. Drought Monitor could improve. Still, exceptional drought, the monitor’s most severe category, expanded further across Northern New Mexico last week. That means the coming storms may bring some short-term relief even as the broader drought picture remains largely unchanged.
Tuesday through Thursday carry the greatest flood threat
Forecasters have singled out Tuesday, Wednesday and Thursday as the most active days for heavy rain. Santa Fe faces at least a slight 15% risk of excessive rainfall on all three days, and Tuesday’s setup includes an enhanced chance of rainfall heavy enough to trigger flash flooding. The highest danger will be in places that are struck more than once by storms.
Tuesday should bring scattered to numerous showers and storms across most of New Mexico, with a few storms in northeastern parts of the state possibly becoming strong or marginally severe. Wednesday is expected to feature widespread showers with scattered storms embedded throughout, while Thursday should look similar, though storm coverage will favor western and central areas more strongly.
Ruidoso burn scars face the highest repeated flash-flood danger
The burn scars near Ruidoso remain one of the state’s most vulnerable areas. Forecasters say they will face a moderate flash-flood risk Tuesday, a high risk Wednesday, and another high risk Friday after storms spread across the region. Burn scars can turn dangerous quickly because fire-damaged ground sheds water more efficiently than undisturbed land.
That repeated danger is one reason officials are watching the forecast closely. Heavy rain falling over the same area more than once can produce runoff fast enough to send water into washes, low crossings and roadways. Even when storms are scattered, the presence of burn scars makes localized flooding a major concern whenever intense rainfall develops nearby.
Temperatures will ease in the north but remain hot in southeast New Mexico
The stormy pattern should bring some relief from heat in much of the state. Highs are expected to fall into the 70s and 80s across much of New Mexico, while places such as Chama and Angel Fire could cool to the upper 60s by Thursday. That change will be welcomed after a summer that has already been unusually hot in several areas.
Not every region will cool down at the same pace. Southeastern New Mexico is expected to stay in the 90s on Tuesday, keeping the risk of heat-related illness elevated for people who are especially sensitive to high temperatures. By Friday, drier air will move into northwestern New Mexico, and storm coverage is expected to ease over the weekend, though isolated to scattered showers and storms may still produce localized flash flooding.
