A few storm updates following my session Wed PM:
Event still largely on track, but two modest shifts that could affect impacts:
1) Storm may not be quite as warm across central & northern Sierra; could see some very heavy snowfalls above 6,500 ft once again.

2) Rainfall may be a bit heavier and more concentrated across the northern portion of central CA (but slightly less to north). This means flood risk in Monterey County (including Big Sur Coast), as well as southern Sierra & foothills, has increased somewhat. #CAwx [2/5]
3) Still not expecting widespread major river flooding. HOWEVER, localized significant flooding of creeks & streams is likely, and *possibly* on a few smaller rivers in the above-mentioned areas, due to combo of heavy rain & snowmelt below ~4,500ft elev. #CAwx [3/5]
4) Another major concern is structural damage and possible avalanches in unusual places due to extreme snow loading (including added mass of rainwater absorbed by high elev snowpack). This could pose major problems in populated parts the higher Sierra. [4/5] #CAwx
5) Active pattern continues next wk, which could include an additional warm AR (though current indications are that it would likely be weaker). Still, today's event will prime watersheds for rapid response...so stay tuned for updates re: medium term flood risk. [5/5] #CAwx
