Tides:

High tides may be of concern if these upcoming storms induce a residual increase, as is usually the case.  Peak tides of concern are 5.9-ft Wednesday morning and 6.23-ft Thursday morning (see tide chart below).  There is a 7.02-ft peak predicted for Sunday morning, but there shouldn’t be much of a residual.  Note that these predictions are for the Golden Gate Bridge tide gage.  At specific locations throughout the north bay, peak times will be later and heights may vary, but typically not by much.

For long-range forecast though January-February-March the NWS prediction models are still indicating below normal precipitation with above normal temperatures.
