On Tuesday afternoon, ABC7 Meteorologist Drew Tuma gave an update saying a Flood Watch has been issued for the entire Bay Area Thursday afternoon into Friday. He says we are expecting to see areas of localized flooding on roads and smaller streams and creeks.
RAINFALL IMPACTS
The highest rainfall totals will be found in the higher terrain of the North Bay and Santa Cruz Mountains where shallow mudslides are possible as soils are fairly saturated from recent rain. The threat for roadway flooding and stream flooding will be highest on Friday morning across the Bay Area.
Initial estimates for rainfall Thursday p.m. - Friday:
North Bay 2"-5"
SF & Peninsula 1"-3"
East Bay 1"-3"
South Bay 1" - 2"
Santa Cruz Mountains 2" - 5"

WIND IMPACTS
We will see damaging winds Thursday night into Friday morning with gusts of 30-50 mph+. This will bring trees down and will likely lead to isolated power outages.
SIERRA SNOW/RAIN
High snow levels above 7,000 ft mean fewer areas will be impacted by snow. Still likely to see 1 - 3 feet of snow in areas that remain cold enough for it. Areas below 7,000 ft will see all rain with some areas exceeding 6"+ of rainfall.
