9/15/2026: Our final days of Summer will likely feel more like Fall. We have a chance of night/am drizzle at times w/ temps mostly in the mid to upper 80s inland into the weekend along with cool mornings. More interesting changes could be lurking down the road…stay tuned on that.

9/13/2026 Some warming is expected to start the week but not to the levels (hottest of the year bayside) we saw last week. Try and breezy conditions will likely keep fire danger elevated across interior NorCal, esp mtn areas through midweek. #BayArea #SanFrancisco #NorCal

A park service assessment of the Dragon Bravo burn scar last summer found that “debris flow risk is localized to steep, confined drainages, like Dragon Creek and upper Bright Angel Creek.”

8/23/2026 the conditions that allowed the #HawkFire to grow aggressively to more than 15,000 acres in 24 hours is a reminder that we’re entering the peak time of year for intense wildfires as live fuel moistures reach their low point with hot, dry and windy conditions leading to red flag warnings.

Mostly upper level smoke from the #TimberFire back in the skies near San Jose. Daytime-like dry conditions at night aka nocturnal drying (dry, warm, windy) gave a boost to wildfire activity & smoke. Areas in the (esp South Bay and East Bay) may notice some smoke at times with hazy skies 8/23/2026

Can confirm the smell of wildfire smoke near Danville. Elevated levels from the inland East Bay and into the South Bay this morning. 8/11/2026

Rob Mayeda NBC Bay Area @robmayeda.bsky.social · 11/08/2026

Contingent on overnight wildfire activity at the #TimberFire for daytime-like intensity & smoke output… southeasterly wind may transport smoke into the South Bay early Tuesday, before improving into the afternoon. 8/10/2026
