RIVERSIDE (CNS) - A no-burn order will be in effect today for large portions of the Southland due to higher predicted PM2.5 levels. Wood burning is prohibited through 11:59 p.m. Tuesday for all those living in the South Coast Air Basin, including Orange County and non-desert portions of Los Angeles, Riverside and San Bernardino counties, according to the South Coast Air Quality Management District. The order does not apply to mountain communities above 3,000 feet, the Coachella Valley or the high desert. Fine particles in wood smoke, also known as particulate matter or PM2.5, can get deep into the lungs and cause respiratory problems such as asthma.
