- Debris Flow and Damaging Winds in New Mexico, July 8, 2025The monsoon high was centered over the Arizona and New Mexico border July 8th. Daytime heating combined with rich Gulf moisture along the east slopes of the Sacramento Mountains resulted in the development of thunderstorms over the west end of the South Fork burn scar during the…
- Flash Flooding and Debris Flows in New Mexico, June 19 to 23, 2024A burst of monsoon moisture surged into eastern NM the morning of June 19th and surged through the gaps of the central mountain chain bringing high wind gusts of up to 58 miles per hour to parts of the Albuquerque metro that afternoon and evening.
- Flash Flooding and Debris Flows in New Mexico, June 29 to 30, 2024A burst of record level monsoonal moisture flowed into NM coupled with a backdoor frontal boundary moving through eastern NM. This yielded scattered to numerous afternoon thunderstorms developing over the high terrain of central and western NM on June 29th.
- Tornado and Flash Flooding in New Mexico, June 24 to 26, 2026The season's first rendition of the North American Monsoon high developed over south-central and southwestern NM with increased low-level moisture intruding beneath it.
- Tornado and Flash Flooding in New Mexico, July 27 to 31, 2025A disturbance rotating north around the upper high circulation centered over south central U.S. followed by a backdoor front entering eastern New Mexico in the middle of the week increased monsoon moisture and shower and thunderstorm coverage across the state.
- Flash Flooding and Debris Flow in New Mexico, July 20 to 24, 2025A new multi-day plume of monsoon moisture advected northward into New Mexico between an upper level trough over the southern Baja Peninsula and an upper high over the south-central CONUS.
- Flash Flood and Debris Flows in New Mexico, August 8, 2022Despite the upper-level high pressure system building over the Four Corners, a backdoor cold front moved southward through eastern and central New Mexico on August 8, 2022.
- Flash Flooding and Debris Flow in New Mexico, June 26 to 28, 2025Despite a relative downtick in monsoon moisture over the weekend, slow storm motions of thunderstorms developing near or directly over the Ruidoso area burn scars resulted in flash flooding on June 26th and 28th.
- Flash Flooding and Debris Flow in New Mexico, August 26, 2025Higher moisture moved into eastern and central New Mexico behind a backdoor front resulting in a greater coverage of showers and thunderstorms across the middle Rio Grande Valley, central mountain chain, and northeast New Mexico.
- Flash Flooding and Debris Flow in New Mexico, August 1 to 2, 2025The monsoon high was centered across southeast Arizona and southwest New Mexico on August 1st and 2nd.
- Flash Flood and Debris Flow in New Mexico, August 11 to 12, 2025Abundant moisture pushed up to the east slopes of the central mountain chain of New Mexico. Combined with daytime heating, this initiated severe thunderstorms along the east slopes of the Sangre de Cristo Mountains southward along the central highlands.
- Tornadoes and Debris Flows in New Mexico, August 17 to 19, 2025A traditional monsoon flow on the western flank of an upper level high over the central U.S. combined with daytime heating resulted in the development of shower and thunderstorm activity across the higher terrain during the early through late afternoon hours.
- Debris Flow in New Mexico, August 20, 2006After several weeks of daily rains, a rocky hill side collapsed onto Hyde Park Road leading to the Santa Fe Ski Basin.
- Debris Flow in New Mexico, October 15 to 16, 2025An upper level low moving through the Intermountain West resulted in shower and thunderstorm development across north central New Mexico during the evening hours of October 15th into the early morning hours of October 16th.
- Debris Flow in New Mexico, September 18, 2025Higher moisture lingered across southern New Mexico on September 18th. This higher moisture along with a backdoor front along the east slopes of the Sacramento Mountains resulted in shower and thunderstorm development across the mountain range and burn scars surrounding Ruidoso…
