April 29 to May 4 - Strong and persistent NW winds over the past few days has kept air pollution levels low and also triggered the upwelling of cold water along the coast resulting in the re-development of our morning coastal fog. Over the weekend, the flow becomes offshore as a Pacific high builds in along the West Coast. The generally breezy spring conditions are expected to persist through the forecast period which should keep air pollution levels low over most of the region. However, as the atmosphere stabilizes over the weekend, ozone levels in the warmer inland areas such as Pinnacles National Park may see ozone levels reach the MODERATE air quality category of EPA’s Air Quality Index (AQI).
