A large south swell is bringing elevated to high surf to the southern California coastline, especially for south-facing beaches. Actions: Remain off rocks and jetties, always keep an eye on the ocean, and follow local lifeguard advice before swimming. Another southerly swell combined with increased tides will bring a threat for coastal flooding around Saturday into early next week.
High pressure combined with offshore winds will lead to significant warming on Wednesday, especially for coastal portions of Santa Barbara and San Luis Obispo Counties. Prepare for the heat by adjusting plans to avoid the outdoors during the peak heat of the day, and seek air conditioning and shade. Always check before leaving your vehicle, that no one was left inside. Parked vehicles can become hot rapidly, and endanger anyone left inside.
Conditions will be warming through the week as high pressure builds over the area. Areas of nighttime to morning marine layer clouds with patchy fog are possible near the coasts through Thursday morning, but low clouds are expected to expand heading into the weekend impacting the coasts, coastal plains and into the valleys.
