Air Quality Alert. Ozone Action Day, Saturday 09/26 and Sunday 09/27

Tomorrow's outlook calls for partly cloudy skies with warm and muggy conditions. Inland high temperatures will range from 93 to 97°F, while beach high temperatures will range from 89 to 93°F. A light southeast breeze at 5 to 10 mph is expected throughout the day.

Warm conditions to continue through this weekend and into next week, with highs ranging in the mid 80s to mid 90s. Rain chances ramp back up toward the middle of next week, coinciding with a rise in tropical moisture and greater sea breeze activity.

A passing upper-level disturbance is forecasted to interact with moisture from the Gulf and eventual remnants of Hurricane Polo. As this system moves to our north and east, periods of heavy rain are possible starting Wednesday, with peak rain chances on Thursday and Friday. Therefore, a Slight Risk (level 2 of 4) of Excessive Rainfall has been issued for Wednesday for our northwestern counties, with the rest of our region having a Marginal Risk (level 1 of 4). Remain weather-aware and stay tuned for forecast updates!
