Rare sighting of a fogbow- not a rainbow, but a fogbow, look that up- on San Benito Mountain this morning from the @alertcalifornia.bsky.social webcam

The view from the top of one of the ~2000-foot-tall telecommunications towers at Walnut Grove, California, this morning. The stratocumulus clouds are below, so from the perspective of the tower cam, it's what's known as an undercast.

Radiation fog fills the valleys near my childhood home in Contra Costa County, California at sunrise this morning. November is shaping up to be a very wet month in California. @alertcalifornia.bsky.social Lafayette Lucas cam.

Aurora now BLAZING red at Likely Mountain 2 @alertcalifornia.bsky.social webcam in far northeastern California. Altocumulus clouds add nice effect.

Aurora tonight in California? Seems like it's gotta be! From the Likely Mountain 2 webcam site, in far northeast California, from the ALERTCalifornia network. Watching the time lapse you can see pillars or curtains of greenish and yellowish light move across the red sky.

A few small dust plumes blew off Owens Lake, California today during a high wind episode. Back when I was doing research there in the early 1990s, the entire Owens Valley could fill with dust on such a day.

Last year, Jamaica, the nation, sort of took up a nationwide hurricane insurance policy, w/payout based on the central pressure of a storm if one hit certain sectors of the island. Melissa hit with a pressure far beyond the threshold- and Jamaica's gonna get $150 million

Melissa has made landfall as a Category 5 hurricane near Bluefields Beach, Jamaica. The large Kingston metro area is likely to be spared extreme winds, but watch for flooding. Montego Bay is in much wind danger. Island's main agricultural region is getting hit by the eyewall: big ag damage looming?

It looks like the outer eyewall of Melissa is now just beginning to hit land near Font Hill, Jamaica, on the southwestern coast of the island. The majority of the island and its population will be on the right side of the eye- which is probably not good from a damage standpoint.

Sun sets on Jamaica and Hurricane Melissa tonight (GOES-19 image). This is a Category 5 storm. Jamaica might not be the same for a long time after tonight.

Hurricane Melissa this morning, just south of Jamaica, Category 5. If you look closely you can see the sun shining on the upper left part of the eye, due to the "stadium effect," the clouds around the eye having the form of a giant stadium. Jamaica is almost certainly in big, big trouble.

Hurricane Melissa, just before the sun set over the Caribbean tonight. GOES-19 image. A clear eye, and starting to look like a buzz-saw. South of Jamaica but about to make a beeline for it. Could be one of the worst disasters ever for Jamaica in the next few days.

El Paso is now over 9 inches of precipitation for the year- more than we’ve gotten in a full year since 2021 and more than the long-term average for a full year going back 145 years (which is 8.7”) #txwx
