County's January precipitation is above average
San Juan County is below average for snowfall and above average for precipitation this month, according to weather data
FARMINGTON — The amount of precipitation San Juan County has received this month is above average compared to previous years, but, so far, the county is below average for snowfall.
Randall Hergerst, a meteorologist with the National Weather Service, said Farmington measured 0.73 inches of liquid precipitation — including snowmelt — this month. On average, he said, Farmington receives 0.61 inches in January.
Hergerst said that while the amount of precipitation is higher than normal, it's not unusual.
"I wouldn't consider it a record wet year by any means," he said.
The weather station at the Farmington Agriculture Science Center measured 0.6 inches of snowfall so far this month, well below its average of 2.4 inches, Hergerst said. Aztec Ruins National Monument also recorded less snow than average. The national monument averages 5.1 inches of snow in January, but, so far, it was only received 2.6 inches this month.
Sunday night's storm brought about 0.004 inches of snow to the area, and a previous storm on Jan. 21 brought 0.0021 inches, Hergerst said.
Despite less-than-average snow accumulation in the valleys, snowpack in the mountains is above average, according to the U.S. Bureau of Reclamation. The bureau's Upper Colorado Region snowpack conditions map shows above average snowpack in the San Juan River basin.
While today was relatively sunny, clouds began to move into San Juan County in the afternoon. The National Weather Service issued a winter weather advisory at 4:54 a.m. today that will be in effect for portions of northern and western New Mexico until 5 a.m. Tuesday. According to the forecast, parts of northwest New Mexico could see up to an inch of snow.
The advisory warns that roads, including U.S. Highway 550, may be icy and have limited visibility. Road conditions can be checked online at nmroads.com.
Hergerst said this will likely be the last storm San Juan County sees this month. He said the long-range forecast shows the storm systems moving north and affecting the Great Lakes region, rather than the Southwest.
