Extraordinary wildfire conditions are forecast for Northern California on Sunday, with the National Weather Service predicting powerful and dry Diablo winds — the kind that quickly spread the devastating wine country fires of 2017 and 2019. Daniel Swain, climate scientist with UCLA and and the National Center for Atmospheric Research, wrote in a blog post that “vegetation is now at or near record dryness levels — much as it was prior to the North Bay firestorm in October 2017.”  “This is a very concerning forecast,” Swain wrote.
