Oct 20 - 23 Critical fire weather conditions for all areas especially the Santa Cruz Mountains. A low pressure trough sits over the Pacific Northwest while a high pressure system builds a ridge out over the Pacific and a smaller low pressure cell still approaching from the SW. The resident low pressure trough is maintaining the current low humidity and strong gusty offshore winds conditions the past several days is expected to continue through Wednesday this week. The pleasant temperatures that we have been experiencing the past few days will continue into the weekend with a further decrease in daily temperatures. Low humidity is expected to continue into the weekend. This offshore flow and high pressures ridge is also pushing smoke from wildfires to the north and east to the Central Coast. AQI for PM2.5 will be in the GOOD and MODERATE range. PM10 is expected to be GOOD in most areas however, Salinas Valley and other inland areas may experience MODERATE AQI for PM 10. Ozone expected to be GOOD.
