Rocky Mountain Complex Incident Management Team 3 would like to extend our deepest gratitude to the communities of Rio Blanco and Garfield Counties for allowing us to serve you these past two weeks. You welcomed us initially out of need, but we have continued to feel your support throughout the incident. We know our presence has a tremendous impact on your small communities, but you have shown us warmth, friendliness, and community spirit. The new team is fortunate to continue the necessary work on the Elk and Lee fires in such an openhearted community.

Yesterday: Lee Fire – Firefighters focused on mopping up hotspots on the south and west sides of the fire, to strengthen and secure containment lines. County Road 5 remains a priority. Crews continued to patrol and monitor along Highway 13, as well as the north and northwest portions of the fire. Unmanned aerial systems (UAS) flights helped identify remaining heat along the perimeter of the fire. Crews also continued construction and clean-up of contingency lines south of the fire.
Elk Fire – Evaluation and implementation of suppression repair work continued. Crews are repairing dozer lines, hand lines, and other areas impacted by firefighting efforts to prevent future erosion and sedimentation.
Current Situation :
Lee Fire – Crews will monitor containment lines, hotspots, and any islands of unburned fuel. Light smoke may be visible today as temperatures rise, giving firefighters a chance to address remaining heat. Firefighters will mop up along the south and west sides of the fire and the County Road 5 corridor. Crews remain engaged protecting structures and other values at risk while reinforcing containment lines in those areas. Rocky Mountain Area Complex Incident Management Team 3 is coordinating closely with the Bureau of Land Management and other agencies to plan future repairs that meet established Lee Fire – Crews will monitor containment lines, hotspots, and any islands of unburned fuel.

Rocky Mountain Area Complex Incident Management Team 3 is coordinating closely with the Bureau of Land Management and other agencies to plan future repairs that meet established standards.
Elk Fire: Suppression repair efforts for the Elk Fire will continue. Crews are covering contingency lines with soil and spreading vegetation to help restore areas affected by firefighting operations to near pre-fire condition.
Weather & Fire Behavior: High pressure will strengthen today leading to hot, dry, and sunny conditions with highs near 86 degrees. Winds will be light and variable, generally out of the west, 5 to 10 mph in the afternoon. A drying trend is expected today through Wednesday. Some remaining hotspots dampened by rain over the last few days will likely show light smoke as fuels dry. Fuel moisture remains low, and significant precipitation would be needed to return levels to normal.
Notas importantes: La escuela comienza hoy en el Distrito Escolar de Meeker. Tenga cuidado al conducir, ya que el trafico escolar y el tráfico de bomberos estarán en las carreteras. La Oficina del Sheriff del Condado de RÃo Blanco degradó varias zonas de evacuación el sábado. Verifique su zona de evacuación en el mapa interactivo: http://bit.ly/lee-fire-zones. La autopista 13 está abierta con una reducción del lÃmite de velocidad de 50 mph. No hay paradas a lo largo de la carretera, excepto en caso de emergencia.

Incendio Elk – Continuó la evaluación e implementación del trabajo de reparación de supresión. Las cuadrillas están reparando las lÃneas de topadoras, las lÃneas manuales y otras áreas afectadas por los esfuerzos de extinción de incendios para evitar la erosión y sedimentación futuras.
Situación actual: Incendio Lee – Las cuadrillas monitorearán las lÃneas de contención, los puntos crÃticos y cualquier isla de combustible no quemado. El humo ligero puede ser visible hoy a medida que aumentan las temperaturas, lo que les da a los bomberos la oportunidad de abordar el calor restante. Los bomberos limpiarán los lados sur y oeste del incendio y el corredor County Road 5. Las cuadrillas permanecen comprometidas protegiendo estructuras y otros valores en riesgo mientras refuerzan las lÃneas de contención en esas áreas. El Equipo 3 de Manejo de Incidentes del Complejo del Ãrea de las Montañas Rocosas está coordinando estrechamente con la Oficina de Administración de Tierras y otras agencias para planificar reparaciones futuras que cumplan con los estándares establecidos.
Incendio Elk – Continuarán los esfuerzos de reparación de supresión para el incendio Elk. Las cuadrillas están cubriendo las lÃneas de contingencia con tierra y esparciendo vegetación para ayudar a restaurar las áreas afectadas por las operaciones de extinción de incendios a una condición cercana a la anterior al incendio.

8.18.25, 6:54 a.m. – Good Morning, It was a quiet night on the fire. As the Incident Management Teams transition today, some crews will begin the demobilization process, but many firefighters and crews remain actively engaged on the scene. Their work continues as they patrol the area, monitor hot spots, reinforce containment lines, and carry out suppression repair efforts. The response is ongoing, and dedicated personnel are still hard at work.
Crews made progress today with increased containment on the Lee Fire. An infrared flight using an unmanned aerial system (UAS) confirmed no heat outside of the fire perimeter. The fire was quiet, and firefighters will keep watch overnight.

Rocky Mountain Complex Incident Management Team 3 is nearing the end of its 14-day assignment. Another team, the Northern Rockies Complex Incident Management Team 1, has been mobilized to assume command of the fire. The new team will arrive tomorrow and shadow RMCIMT 3 to ensure a seamless transition in strategic firefighting and fire suppression repair operations. The new team will meet with each section of Team 3 and be provided with all transition information. They will take full control of the incidents on Tuesday morning.
IMTs are part of a national system of firefighting resources that are called in when the local fire situation exceeds the capacity of agency managers to handle. Each team is assigned for 14 days to ensure that team members have the opportunity to rest between assignments. This is essential for safe operations on an incident.
Rocky Mountain Complex Incident Management Team 3 would like to thank the communities of Rio Blanco and Garfield Counties for allowing us to serve you during this assignment.
