Bald Sisters Fire Smoke Update for Sep 22, 2014

Bald Sisters Fire
Air Quality Update for 9/22/2014  by  Dan Chan

Yesterday:
Air quality monitor at John Day measured “Moderate” amount of smoke yesterday. The fire growth was estimated to be 250 acres and this created smoke columns up to a mile high.  However, because of the mostly southwesterly wind last night, smoke settled in drainages to the northeast of the fire and only relative small amount came into Prairie City this morning. 

Today:
John Day measured less smoke this morning than yesterday.   Southeasterly wind is expected for tonight.  Smoke is likely to settle into the John Day Valley, increasing the smoke concentration at Prairie City and John Day tonight and tomorrow morning. 

Tomorrow: 
Strong Southwesterly wind is expected ahead of an approaching cold front from the coast.  This will transport most of the smoke to the northeast of the fire.
