Weather models continue to gain confidence and near unanimity in their forecast of a record-setting wet winter in parts of California, fueled by El Nino's warm storms and crashing waves.

So reported University of California Agriculture and Natural Resources climate scientist Daniel Swain in an online update on Tuesday.

We're in a year where we could see three times the average annual rainfall in places in California that are quite wet, Swain said.

In general, there is agreement in all of the models of record-breaking precipitation in at least one month this winter, he added.

Temperatures are expected to be much warmer than average with warmer than normal ocean conditions.

Waves that are already about two feet higher than normal as far north as San Francisco could surge during king tides, which are high tides during a new moon or full moon.

Even moderate storms during king tides could produce widespread coastal flooding, Swain said.

He noted that king tides are expected to coincide with heavy travel season around Thanksgiving weekend.

Southern California got a potential preview of what the winter could bring last weekend when Tropical Storm Rachel brought the first major rainstorm of the water year.

The storm that arrived on Saturday dumped as much as six inches of rain on parts of San Diego County over a 72-hour period that, according to the National Weather Service, Oceanfront homes in coastal California cities such as Long Beach and Newport Beach partially submerged as heavy surf breached land berms, according to National Public Radio.

Dry weather, warmer temperatures, and gusty winds are expected to persist in much of California through this weekend.
