I’ve never seen the sky this colour in the years I’ve lived here, somewhere between Methyl Violet and Lobelia Blue. It has an unreal feel to it, like the old Stereoscope cards from the 1950s. And it comes on the heels of two nights of unprecedented lightning strikes that went on for hours, like slow-motion, erratically staggered strobe lights, along with the distant rumble of thunder. There is, very rarely, every few years, a bit of thunder and lightning during the summer in San Francisco, but I can recall nothing remotely like this. A high wind has suddenly kicked up, ominously bending the large palm in the backyard, freighted with decades of unpruned dead fronds and bedizened with thick ropes of trumpet vine with its orange flowers.
