Light and scattered rainfall tapered off Wednesday night but will return in a second wave Thursday evening.
The NWS issued a wind advisory for the mountains and deserts that will expire at 7 a.m. Thursday. Wednesday rainfall totals stayed below a third of an inch.
The storm system first pounded the Los Angeles area with heavy rain and lightning strikes but lost most of its strength as it moved over San Diego overnight Monday.
Showers began late Tuesday and continued into Wednesday morning, beginning in the North County and heading south, and saturated roads during Wednesday's morning commute.
NBC 7 Meteorologist Dagmar Midcap said Friday and Saturday are looking dry for the most part, but a third wave of light rainfall could douse the county Saturday night and on Sunday.
The storm system wasn't expected to fully make its way out of the region until Friday, at which point the storm could dump up to an inch of snow on San Diego's mountains, Parveen said.
In total, the storm isn't expected to drop more than an inch of rain on San Diego County over the three-day period.
"As [the storm] continues to slide south, which it's doing very slowly, it's going to pull in some moisture from the Pacific. So locally we’re not seeing too much but cloudy skies and sprinkles," Parveen said.
So far, the most precipitation has fallen in San Diego's mountains, where some peaks have seen more than a quarter-inch of precipitation through 4 a.m. Tuesday, according to the National Weather Service.
Up to a tenth-of-an-inch of rain fell on inland areas and even less had fallen along the coast and in the deserts.
Along with rain, the storm system was increasing winds in the mountains where a wind advisory was issued by the National Weather Service until 7 a.m. Thursday. During this time, wind gusts could reach speeds of 50 miles per hour.
Conditions are expected to dry out in time for the weekend but another storm system is expected to bring rainfall late Sunday into early next week, Parveen said.
