A 10 to 20 percent chance for rain and thunderstorms continues into Saturday evening and overnight into Sunday morning.
Highs along the coast Saturday were in the low 70s and in the upper 60s inland.
A beach hazard statement is in effect until 10 p.m. Sunday with an elevated surf and strong rip currents. "There's a risk of cloud-to-water lightning, so you don't want to be in the water when that happens," NBC 7's Liberty Zabala said.
By Monday morning, a fire weather watch will be in effect until Tuesday evening and wind gusts could get up to 60 mph.
Friday evening, thunderstorms brought lightning, hail and showers to some parts of the county and even forced a delay at San Diego State's game against Air Force.
With SDSU leading 14-9 at the 5:50 minute mark in the third quarter, referees called a 30-minute delay to wait for aggressive lightning in the Mision Valley area to subside. After a second 30-minute delay, the teams took the field and finished the game.
