Discussion for August 25 to 29 – A ridge of high pressure centered over the 4-Corners States expands westward over the Central Coast early in the week leading to slightly above normal temperatures and a shallower marine layer which will allow the coastal low clouds and fog to burn off earlier in the day. Although haze may still be visible at times, this pattern should continue to spare the Central Coast from major smoke impacts caused by fine particulate matter (PM2.5) from the various wildfires burning in California and the PacNW. The lingering haze is likely caused by recirculation and the complex wind patterns that transport the smoke over long distances. PM2.5 air quality for fine particulate matter, as illustrated in the accompanying charts, should generally remain in the GOOD to lower MODERATE categories of EPA’s Air Quality Index (AQI) and well within EPA’s health based ambient air quality standard for PM2.5. By the end of the week, a robust low pressure system moves into the PacNW from the Gulf of Alaska leading to cooler temperatures over the Central Coast. In the Salinas Valley, dry soils coupled with strong afternoon breezes may cause PM10 AQIs at King City to occasionally reach the MODERATE category due to windblown fugitive dust. Please note, due to the long-term drought, CAL FIRE has suspended open burning in all State Responsibility Areas of Monterey, San Benito and Santa Cruz Counties. During these extremely dry conditions, residents are also cautioned about the high risk of causing a wildfire when using any ignition source near dry grass and brush.
