The Bay Area is now into the 11th day of unhealthy, Spare the Air conditions due to wildfire smoke and strong high pressure trapping locally produced pollution as well. Spare the Air conditions are expected to continue to at least Tuesday afternoon before increasing winds and rain returning by Wednesday bring improved air quality midweek.
For those with holiday travel plans on Wednesday, expect rain at times and snow and windy conditions at times into the Sierra for wintry roadways. Rain totals by Friday look to be the highest we’ve seen region-wide since April 6th, the last time most of the Bay Area saw about 1” of rain. So we’ll lose the weather alert status for air quality but could see new ones going up for rain coming in, esp early Friday where 1”-2” rain could be possible for the North Bay and coastal mountains.
Higher rain totals will be possible in the North Bay mountains and unfortunately near the Carr Fire and recent Camp Fire burn scars, which could lead to debris flows and will need to be monitored.
