"San Jose's air was so bad Tuesday that it ranked second-worst in air quality in the United States for a few hours, behind Bakersfield."
"This year, however, Northern California is on pace for the driest calendar year since 1850, when records were first kept."
"The fire that burned piles of appliances at Sims Metal Recycling in Redwood City and the Pfeiffer Fire in Big Sur brought more haze across Monterey Bay and into the Bay Area."
"...San Jose a reading of 94 micrograms per cubic meter for particle pollution at noon Tuesday. The federal health standard is 35. Oakland peaked at 68 and San Francisco peaked at 70."
Honestly I'm surprised the readings weren't higher.
