Overall smoke impacts are forecast to be “Moderate” to “Unhealthy for Sensitive Groups” with periods of “Unhealthy” depending on weather and location. Smoke levels will vary depending on weather conditions and fire activity. The light northerly daytime wind has brought some improvement to coastal areas. As is typical for this time of year, overnight inversions will limit smoke dispersion until the day starts to warm up. This pattern is expected to continue for the next couple of days.
