You might want to watch the ball drop inside, safe and warm on your couch.

The National Weather Service predicts another round of wet weather in the Bay Area starting to rear its head on Tuesday and lasting through Friday. 

Wednesday, New Year's Eve

What we know:

Rain is in the forecast on Wednesday, beginning in the South Bay and Peninsula in the morning, which will then spread to the rest of the Bay Area by afternoon.

The heaviest rainfall is expected in the North Bay, Santa Cruz Mountains and along the Big Sur coast, where totals could reach 4 to 6 inches by Sunday. 

Most other areas are forecast to see between 1 and 3 inches of rain, the NWS said.

Forecasters say the rain could cause flooding in low-lying neighborhoods, urban streets and poor drainage areas, along with fast-rising creeks and streams.

Confidence in the rainfall forecast is moderate, with lighter rain expected into the following week.

Thursday, New Year's Day 

Rain is being forecast for New Year's Eve and New Year's Day, where there will also be a lot of wind, according to the NWS. 

As of now, the Port of San Francisco website shows the 15-minute fireworks show in San Francisco at midnight is still on – and free. And there's no word what will happen if there happens to be a downpour. 

In addition to the rain, there will be high wind gusts and King Tides along the coast

Friday, Saturday and Sunday

Strong winds may add to the impacts late Friday into early Saturday. The weather service said unsecured objects could be damaged, and some tree damage is possible during that period.

The weather service urges residents to stay aware of changing conditions, especially near the coast and in flood-prone areas, as the busy holiday period approaches.

Showers will begin to taper off on Saturday.
