Here is this week’s weather forecast by PG&E meteorologist John Lindsey.

A fast-moving, 998-millibar storm was forecast to bring increasing southerly winds, clouds and rain showers Sunday evening. The associated cold front should produce strong to gale-force (25 to 38 mph) southerly winds along the coastline and moderate to heavy rain Sunday night into Monday morning. Rain will turn to scattered rain showers Monday afternoon and night.

Another cold front could become a moderate-strength atmospheric river event that will produce strong to gale-force (25 to 38 mph) southerly winds and periods of heavy rain late Monday night through Tuesday, turning to showers by Wednesday morning.

Both of these low-pressure systems will tap into a large plume of subtropical moisture. Consequently, temperatures will be mild and rainfall heavy. Total rainfall amounts from Sunday night into Tuesday are forecast to range between 1.75 and 3.5 inches, with much larger amounts in the Santa Lucia Mountains.

Possible mudslides could develop in the higher terrain of the coastal mountains. Snow levels in the Sierra Nevada will be above 7,500 feet by Tuesday. A break in the rain is expected Wednesday afternoon through Thursday evening, before another low-pressure system produces rain Thursday night into Friday. At this time, it’s looking dry from Saturday into Feb. 15, before another round of wet and unsettled weather is forecast to start Feb. 16.

Surf report

Sunday’s 4- to 6-foot west-northwesterly (285-degree, deep-water) swell (with an 8- to 17-second period) will become 7- to 9-foot southwesterly (240-degree, deep-water) sea and swell (with a 5- to 15-second period) along the coastline late Sunday night into Tuesday.

A 4- to 6-foot westerly (270-degree, deep-water) swell (with an 11- to 13-second period) is expected along our coastline Wednesday into Thursday. This westerly swell will increase to 8- to 10-feet (with an 11- to 14-second period) Friday into Saturday.

Seawater temperatures

Seawater temperatures will range between 54 and 56 degrees through Friday.
