Bald Sisters Fire Air Quality Update for 9/24/2014

Bald Sisters Fire Air Quality Update for 9/24/2014  by  Dan Chan

Yesterday:
John Day, Unity and Baker City measured “Good” air quality yesterday.  Although lightning from previous night started half a dozen new fires yesterday, they were promptly contained by local fire crews.  Most of the resourced from the Bald Sisters Fire were demobed yesterday as well. 

Today:
Limited fire growth and thus limited smoke production is expected for today due to moist fuel condition on the ground.  Southwesterly wind is expected for today.  In the evening, wind will weakened and smoke from Bald Sisters fire is likely to settle onto the North Malheur River Valley and drainages to the south of the fire.  

Tomorrow: 
Rain is forecast to arrive at John Day tomorrow morning.  The rain band will move east and is forecast to exit Unity by night fall.  Southerly wind is expected during the day and this will push smoke, if any, to the north of the fire.    

No further update will be provided for this fire until further notice.
