The National Weather Service (NWS) in Albuquerque has issued an update on an upper level disturbance that will be impacting northern and central New Mexico through Friday.
An unseasonal upper level disturbance is currently tracking eastward through Arizona. This disturbance will advance into western and central New Mexico this afternoon and into the evening.
By Friday this weather system will track toward the northeast corner of New Mexico before exiting.
Abundant atmospheric moisture is in place ahead of this feature, and scattered to numerous thunderstorms are expected to erupt as it enters the state.
While individual thunderstorms are expected to move to the east northeast between 10 to 20 mph, some of the more vigorous thunderstorms will be capable of producing high rainfall rates, especially in western New Mexico.
A Flash Flood Watch has been issued for most areas west of the Rio Grande Valley, as well as the Sacramento/Capitan mountains of Lincoln County.
A Flash Flood Watch means that conditions may develop that lead to flash flooding; it does NOT mean that flash flooding is imminent.
The Las Conchas, Whitewater Baldy, Little Bear, and White burn scars will be especially susceptible to flash flooding this afternoon and this evening.
Summary of Main Hazards and Impacts:
- Rainfall rates of 1.5 to 3 inches per hour will be common with the stronger storms.
- Flash Flood Watch from Noon through Midnight tonight for areas west of the Rio Grande Valley, as well as the Sacramento/Capitan mountains of Lincoln County.
- Localized flash flooding of streams, arroyos, dry creek beds, and low water crossings will be possible from heavy rainfall.
