ALERT

N3B and EM-LA has transitioned back to the “ready” stage of “ready, set, go,” in coordination with LANL and NA-LA, due to improving conditions with the Cerro Pelado fire. The “ready” stage means there is no emergency but residents and employees should create a plan in case they need to leave the area. 

N3B and EM-LA will lift their maximum telework mandate and return facilities and operations to their normal status. With Stage 3 fire restrictions still in effect, however, certain operations remain limited. 

You are encouraged to sign up for local safety alerts by texting LOSALAMOS to 99411.
