Per Daniel Swain at http://www.weatherwest.com:
Due to recent precipitation across most of Northern California, wildfire risk is low during this first low RH/wind event and will likely stay below extreme levels during the second event as well from about the SF Bay Area northward (though with some caveats). This is the benefit of early season precipitation: even though most places in NorCal are actually running behind the seasonal-to-date average for Sep-early Nov (a decidedly noisy statistic!), places that have seen half an inch or more of rain recently will be in pretty good shape. Given that there has not yet been a seasonal green-up yet in most places and conditions will still be quite windy with low humidity for an extended period this week, there may still be some fires (especially in grassland settings) up north–but the likelihood of something big or concerning is fairly low up north (event compared to the mid-Oct event). With no further precipitation expected this week, however, and with the cumulative drying effect of several days of windy/low RH conditions expected to be substantial, it’s still a good idea to prevent errant sparks from igniting unplanned/unwanted fires during this period.
