The Poso Fire on the El Rito Ranger District on the Carson National Forest located 10 miles north of El Rito, adjacent to FR123 and is currently 1450 acres and 18% contained. Cause is lightning.

As aerial and hand ignitions continue, there will be an increase of smoke in the area. Smoke may hang low to the ground at night and in the early mornings the next few days due to the weather phenomenon known as temperature inversion. This occurs when warm air caps the cooler air below it causing smoke to become trapped underneath which will settle into the valley bottoms—most often at night and in the early morning. The trapped smoke generally begins to lift after the sun rises and heats the earth’s surface. The air heated by the earth’s surface will push the colder layer of smoke up into the higher atmosphere and the smoke mixes with the air above and is transported away. Smoke in the air can also be affected by wind speed and direction. If heavy smoke is present, those who are more vulnerable should take precautions such as staying inside and avoiding prolonged outside activity. 

As fire increases in size and firing operations commence, smoke may be visible from the communities of Abiquiu, Canjilon, Cañon Plaza, Vallecitos, La Madera, El Rito, Ojo Caliente, Petaca, Las Tablas and Tres Piedras which may continue to show for several days. For information on air quality and protecting your health, please visit The health and safety of firefighters and the public are always the first priority. Smoke-sensitive individuals and people with respiratory problems or heart disease are encouraged to take precautionary measures. For information on the HEPA filter loan program, go to or contact the El Rito Ranger District 575-581-4554.  
A Temporary 24-Hour Flight Restriction (TFR) is in place over the fire. Unauthorized use of unmanned aircraft (also known as “drones”) in a fire area endangers the lives of pilots and firefighters and is strictly forbidden. Never fly unmanned aircraft over or near a wildfire whether there is a TFR (Temporary Flight Restriction) in effect or not. Visit and Know Before You Go for more information on drones and wildfires.

Weather Concerns

Hot temperatures and meager mid level moisture will bring the low possibility of a stray virga (evaporating rainfall) shower or dry thunderstorm late this afternoon. Any showers or thunderstorms would drift from west to east at about 20 mph. Fair humidity recovery is expected tonight as winds shift southeast, bringing increased moisture. However, the moisture will mix back eastward on Sunday with hot temperatures and only low chances for a thunderstorm returning in the afternoon.
