Bald Sisters Fire Air Quality Update for 9/23/2014

Bald Sisters Fire  Air Quality Update for 9/23/2014  by  Dan Chan

Yesterday:
Air quality monitor at John Day measured “Moderate” amount of smoke yesterday while Baker City measured “Good”air quality yesterday.  The fire growth yesterday was limited by showers of up to 0.59” at the fire.  However, only 0.15” was at John Day and this was not enough to scour the smoke in the air. 

Today:
Limited fire growth is expected for today due to rain overnight.  This will limit smoke production from the fire.  Southerly wind is expected for today.  In the evening, smoke is likely to settle in drainages and valleys north of the fire.  This may bring elevated smoke to Unity and Baker City. 

Tomorrow: 
Southerly wind is expected during the day, but is expected to turn Northerly in the evening.  This should keep smoke close to the fire and should have limited impacts to the nearby communities including John Day, Prairie City, Unity and Baker City.
