From NWS, Bay Area:

Significant rain is likely next week. Here’s a look at the probability of exceeding 1″, 2″, and 3″ from Tuesday-Thursday. Use the weekend to clear the gutters and replace the wipers.

KION tells us: “There is still a lot of uncertainty as to how this trough will impact our area, but there is definitely potential for a stronger storm with gusty winds and heavy rain. There is also some bust potential. Rain could start as early as Tuesday, but the Wednesday-Thursday timeframe is looking more likely for rain & wind. The forecast will likely evolve, so make sure to stay tuned.”
