| Description: |
* WHAT...Large breaking waves will build this morning, peak at 18 to 25 feet this afternoon into Tuesday morning, then will subside slowly during Tuesday. Very dangerous rip currents are expected. For the Coastal Flood Advisory, coastal flooding is expected. * WHERE...San Luis Obispo County Beaches and Santa Barbara County Central Coast Beaches. * WHEN...For the High Surf Warning, until noon PST Tuesday. For the Coastal Flood Advisory, until 9 AM PST Tuesday. * IMPACTS...Flooding of sea water is likely around the times of high tides, over vulnerable low-lying coastal areas such as parking lots, beaches, and walkways. Significant damage to roads or structures is NOT expected. Powerful waves and strong rip currents will pose an exceptional risk of ocean drowning and damage to coastal structures like piers and jetties. Large breaking waves can cause injury, wash people off beaches and rocks, and capsize small boats near shore. * ADDITIONAL DETAILS...High tides between 4.0 and 5.0 feet MLLW are expected each morning between 4 AM and 6 AM. The risk for shallow but impactful coastal flooding is highest during these times, with flooded beach roads and parking lots possible, especially for the Oceano Dunes area.

| Description: |
* WHAT...The South Coast AQMD has extended a mandatory wood-burning ban for residents in the South Coast Air Basin. The No-Burn rule bans burning wood, pellets, and manufactured fire logs in any indoor or outdoor wood-burning device. * WHERE...The South Coast Air Basin, which includes Orange County and non-desert portions of Los Angeles, Riverside, and San Bernardino counties. No-Burn Day alerts do not apply to areas above 3,000 feet in elevation, the Coachella Valley, or the High Desert. Homes that rely on wood as a sole source of heat, low-income households and those without natural gas service also are exempt from the requirement. * WHEN...Sunday and Monday. * IMPACTS...Particles in smoke can get deep into the lungs and cause health problems (including asthma attacks), increases in emergency room visits, and hospitalizations. No-Burn Days are needed to protect public health when fine particle pollution levels are expected to be high anywhere in the South Coast Air Basin. No-Burn Days are based on fine particle pollution levels that are forecasted for an entire 24-hour period, which may not be reflected in real-time air quality maps. |
