New Mexico CoCoRaHS 6-Day Rainfall Totals.
(9 AM MDT Wednesday, August 17 through 9 AM MDT Tuesday, August 23, 2022).


Radar and satellite estimates as per the National Weather Service MRMS site show that 11.41" of rain fell in the area shaded by light blue in the maps above. North of Roswell on the east side of US Highway 285, east of mile markers 39-46, in northern Chaves County.

So far (as of Tuesday, August 23rd) I haven't been able to find any collaborating rainfall reports online to substantiate this. I'm not saying this didn't happen I just don't have anything other than this radar site to verify those rainfall totals. Given the historic flooding on the Pecos River that continues from north of Roswell to south of Artesia due in part to runoff from the excessive rainfall in that area, I personally think these estimates may be valid. No doubt there has to be a rancher or local in that area that actually measured what fell...we can hope right? But getting ahold of that info has been tough so far if in fact, someone did measure that much rain.

Historically New Mexico's official greatest 24-hour rainfall total as measured by the National Weather Service Climate Co-Op Station Network is 11.28" at Lake Maloya in Colfax County on May 19, 1955. 

I am 64 years old and have lived all of my life (except for my time in the US Navy and a short period afterward) in the Artesia, Lakewood, and Carlsbad areas. My mother and stepdad built a grocery store in Artesia in the early 1960's. Our business was predominately with the area ranchers and farmers through the mid 1980's when the family business was sold. I spent my younger years talking with these farmers and ranchers as they shopped in our store...listening to their stories of our floods, droughts, heat waves, winter storms, bitter cold outbreaks, dust storms, etc. Most of this generation has passed away now. 

More than once I've been told that local ranchers have measured rainfall totals (storm totals usually occur over several days to a week, or two) of 10 inches, 20 inches, and even as high as 30 inches of rain in and around the Guadalupe, Sacramento, and Capitan mountains. This has happened occasionally throughout the past 100+ years according to these folks, local newspaper articles, and in some cases in our historical climatology records. 

A  couple of recent cases in point. 

A historic rain event for the Guadalupe Mountains from September 9th-13th, 2013. 15.76 inches of rain was recorded during this period at the Pine Springs, GUMO Mesonet station near the National Park Visitor Center. 13.62 inches of rain fell on September 11th-12th (most of this in a 12-hour period during the early morning hours of the 12th). Flash flooding occurred in the Dark Canyon, Rocky Arroyo, and Black River basins on the 12th with many localized areas of high water along the arroyos on the north side of the Guadalupe Mountains. An impressive fourteen-foot rise of water on the Dark Canyon when it reached Carlsbad, New Mexico.



Another historic heavy rainfall and flash flood event occurred in September 2014. A farmer who lives two miles east of Malaga (southeast of Carlsbad) in southern Eddy County measured a storm total (14-day totals) rainfall amount of 25" from this event. Radar verified his totals also. Another total of 22.25" was measured nearby on Durante road one mile east of Malaga. Closer to town a storm total of 21.50" was measured on Derrick Rd & Old Cavern Highway south of Carlsbad.
