Well, that was weird.
Near-zero sleep. Seemed stormish at bedtime (8 PM) but storms weren't on the radar. At 9 a storm struck. 15 minutes of heavy rain, some wind, one flash and one boom. Good storm by Spokane standards, hardly noticeable by Okla standards.
As the rain faded, I was starting to fade into sleep, but awoke again because the computer had stopped playing OTR clips. Instead, the computer was making a big windy sound. The cooling fan was roaring, with no indication of HD activity. I quickly got up and shut off the power strip then rebooted.
Normal reboot, nothing seems to have been lost or corrupted. I don't think the circuitry was actually hot. Power blink or power surge must have put the computer's CMOS registers into a strange condition.
Big area of Spokane
is still without power; looks like a major Avista substation got hit directly and created a surge.
One of the contributors on the Spokane News facebook page
caught a picture that looks distinctly tornadic.
