Prolonged & locally record-breaking Southern California heatwaves continues; more tropical moisture?

The latest in a recurring series of live, virtual, & interactive #weather and #climate-focused "office hours" hosted by Dr. Daniel Swain. 10/05/2026 topics: I discuss the already severe and locally record-breaking autumn heatwave centered in coastal Southern California but extending across most of the U.S. West, and why it will persist for some days to come. I'll also discuss the potential for the remnants of Hurricane Rachel to affect California and the broader Southwest by next weekend.
