The California Weather Blog has some March drought insight:
In the longer run, it seems likely that a fairly active weather pattern will continue across California for much of March. It’s hard to say at this point whether precipitation this month might approach the remarkable late-season levels of the “Miracle March” in 1991, but it does at least appear likely that California’s snowpack will recover toward or even above average levels in the coming weeks. It’s less clear whether Southern California will be able to make up the seasonal precipitation deficit that has accumulated this year despite the near record-strength El Nino event in the tropical Pacific. Still, it appears increasingly likely that March will at least be able to make a dent–even though it’s quite clear that California’s multi-year drought will persist through the summer.
