High winds blowing dirt and dust from the Sand Fire burn area are creating hazy skies seen in the Santa Clarita Valley Sunday morning, according to the Los Angeles County Fire Department. The hazy sky is not a result of fires according to Tina Cox, a spokesperson for the South Coast Air Quality Management District. “With the Santa Ana winds increasing, we might see winds blowing dust,” she said. She recommends not going outdoors unless necessary. “People could experience respiratory problems with the particles that are in the wind,” she says. Cox says children, the elderly and people with respiratory problems are at the highest risk of being affected by the dust. The National Weather Service has issued a high wind advisory through 3 p.m. Monday.
