SAN DIEGO (KGTV) -- Scattered showers are expected to continue Sunday as the second storm moves out, making way for a third storm system to move in Sunday evening.
According to the National Weather Service, rain will continue throughout the afternoon Sunday before a third storm cell brings lighter precipitation Monday and Tuesday.
"The showers could linger into Wednesday morning. When all is said and done, we could see up to 1.5" of rain along our valleys and coast," the 10News Pinpoint Weather Team said.
The continued rain is causing concern that some parts of the county could experience dangerous flooding.

Areas of concern include Oceanside, Carlsbad, Temecula, Vista, Encinitas, Del Mar, Fallbrook, Valley Center, Camp Pendleton, and parts of the San Diego city limits including University City, NWS added.
"Low-water crossings in many areas will likely flood at some point as larger rivers and streams more quickly develop channel flow, including the San Diego River in Mission Valley," NWS forecasters said in a statement.
As of Sunday morning, rainfall totals over the last 72 hours topped out at more than 2.7 inches in Oceanside and between 1.3 and 2 inches along other parts of the San Diego Coast.
Bonsall and Palomar Observatory each saw more than 3 inches of rain over the last 72 hours.
Winds are also expected to be strong Sunday, reaching up to 40 miles per hour at Lindbergh Field. Along the coast, a high surf advisory is in place until 11 a.m. Monday.
Periods of snow and gusty winds will continue above 5,500 feet into Monday. Snow showers may become heavier late Monday through early Wednesday.
Snow levels are expected to drop as low as 3,000 feet Tuesday afternoon through Tuesday night with accumulations likely, according to the National Weather Service.
