Air Quality Report (As of 7:30am)
Good for all reporting areas.
Weather Story: We have begun the transition from high pressure-dominated warm, dry weather to a more active, wet weather pattern. The ridge ease back to the west, allowing for dry weather system to sneak in from the north overnight. Offshore winds will strengthen as it passes through. Behind the system, winds will calm down, but the air mass will remain mild for the next few days.
A stronger, wetter trough of low pressure will dig down the West Coast on Friday. It will likely push a cold front through our area that will be accompanied by rain. Showers could linger into Saturday and there is a slight chance of an isolated thundershower. Another weather system will move in on Monday or so. Temperatures will be much cooler starting Thursday/Friday and will likely remain that way next week.
From the National Weather Service in Monterey…
High winds have the potential to topple power lines and trees along with creating hazardous driving conditions. Plan accordingly and secure light property outdoors including temporary outdoor structures. Have cell phones charged and flashlights handy if power outages occur.
People should avoid being outside in forested areas and around trees and branches. If possible, remain in the lower levels of your home during the windstorm, and avoid windows. Use caution if you must drive.
