Forecast Discussion: July 26 to July 30 - The Soberanes Wildfire continues to burn in a remote wilderness area between Carmel Highlands and Big Sur where access is difficult. The burn area is largely above the marine layer where humidity is low and temperatures are reaching the 90’s. This will serve to increase fire activity, especially during the hotter daytime hours. Winds over the fire for the near-term are from the southeast which will move smoke northward over Carmel Valley and the Monterey Peninsula where smoke particulate (PM2.5) levels can be expected to reach the MODERATE to UNHEALHTHY FOR SENSITIVE GROUPS categories of EPA’s Air Quality Index (AQI). However, since the fire has been going for several days now, many of the airsheds over the region are experiencing light to moderate smoke and haze. Although most of the smoke remains high above the surface, some of it lays above the marine layer where smoke may reach the surface resulting in MODERATE air quality as the marine layer mixes out near the coast. Also, localized areas near the fire or where more of the plume may reach the ground can be expected to degrade below the level of the air quality standard for PM2.5 and therefore reach the UNHEALTHY FOR SENSITIVE GROUPS category. Persons sensitive to smoke should shelter in place and close windows, or if possible seek relief by leaving the area. High pressure and warmer inland temperatures develop Tuesday through Thursday possibly contributing to further degradation of air quality. The District will update these assessments depending on the evolution of the fire and any related air quality impacts. For the latest air quality information see http://mbard.org/air-quality/ .
