The latest in a long series of storms made landfall in San Diego County Sunday night, dropping nearly 0.75 inches of rain in National City between 5 p.m.

The system was expected to deliver an inch or more of rain to most areas of the county by early Monday and two to four inches of snow on the peaks of Palomar Mountain and Mount Laguna.

Weather service radar indicated at 8:30 p.m. Sunday that overnight rainfall totals could end up topping an inch in some areas, further increasing the chance of mudslides, particularly along coastal bluffs.

The new storm follows in the footsteps of an atmospheric river that blew through the region Saturday afternoon and dumped much more rain than expected in parts of the county Sunday morning.

Fallbrook, Escondido and Ramona each received about 2.5 inches of precipitation and could return to being among the wettest places as the new system moves through the area. (This is the amount of rain 45 communities received on Saturday.)

As of early Sunday, the San Diego International Airport has received 5.32 inches of seasonal rain, which is 1.40 inches above average. Ramona Airport has recorded 9.63 inches, which is 4.25 inches above average.

The weather service said an additional 0.38 inches fell at the San Diego airport between 2:30 p.m. and 8:30 p.m. Sunday.

A high surf advisory will be in effect for the coast until 10 p.m. Tuesday. The waves have been pounding the local beaches for days.

“A slight decrease in swell is possible Monday before another westerly swell (albeit with a slightly shorter period) produces a higher to higher swell Monday night into Tuesday, staying mostly for below 10 feet,” the weather service said.

“Swell will gradually drop Tuesday night and Wednesday, and no high swells are expected the rest of the week.”
