California Weather Blog: A dry start to autumn for most of California as amplified North American pattern continues; Prospects for rain murky

From the California Weather Blog: “A rather extraordinary sequence of atmospheric events has unfolded over the Pacific Ocean and across adjacent North America over the past week or so.

In the Bay Area, Alameda Creek work trickles on

From Ariel Rubissow-Okamoto at Estuary News: Throughout Alameda Creek’s 640-square-mile watershed dozens
 of wet spots have been drained, dams built, creeks buried, and channels reshaped. “The watershed is huge and complex, and all these changes, compounded over time, have left us with a long and arduous path to getting it to function more naturally again. …

California Weather Blog: An overview of California’s ongoing and extraordinary drought: a tale of exceptional dryness and record warmth

From the California Weather Blog: “Droughts historically have a way of sneaking up on California, and the extraordinary 2012-2014 drought has been no exception.
