Air quality results show promise
The results are in for air quality over the month of October, with zero daily exceedances of the National Ambient Air Quality Standard (NAAQS) for particulate matter, or PM2.5, according to the Northern Sierra Air Quality Management District.
As fall crept in and temperatures dropped, Portola saw an increase in particulate matter from wood stove combustion.
October was a very dry month with stagnant weather conditions, and though CalFire lifted the burn suspension as of Oct. 3, there were limited permissive burn days due to fire weather conditions.
Significant fire potential should drop off by the end of November, with the region generally expected to be warmer and drier than normal through February, per Northern California GACC, 10-31-19.
