Air Quality Forecast

November 17 – November 21: Scattered showers will continue Monday with slight chance of isolated thunderstorms as a cold front moves across the region. The sun will peak out on Tuesday before another system brings additional rainfall beginning on Wednesday. Temperatures will range between low to mid 40s up to the high 50s near coastal areas while inland temperatures will be even cooler. Additionally, the NWS is monitoring several cells over coastal waters on Monday with legitimate waterspout potential. The threat of flash flooding is also of concern this week, particularly in areas with “burn scars” from previous wildfires. Ozone levels should remain below State standards, therefore ozone AQIs will remain GOOD. Wet conditions will keep PM10 (dust) AQIs in the Salinas Valley at GOOD. Unsettled weather will improve ventilation and maintain PM2.5 AQI (smoke) levels at GOOD.
