Pelagic - Half Moon Bay, California this Sunday! Great forecast, and conditions are primed for birds and cetaceans. We are trembling with excitement as signs are good that this will be a superb seabird season. Join us - alvarosadventures.com/pelagic-dates-…

This is the Andean Storm-Petrel (Oceanites barrosi) which is a NEW species we have just described in a paper in Zootaxa. We also suggest a re-arrangement of the taxonomy in the group, suggesting multiple splits. mapress.com/zt/article/vie…

Folks, we are not out of the woods yet. We've issued a Fire Weather Watch in effect Thursday until Saturday evening for the potential for strong offshore winds and low humidity. Areas most likely to see impacts are the higher elevations which could see gusts up to 50 mph. #CAwx

Increasing confidence in moderate-strong north wind event across parts of SW Calif on Fri. With drying expected, looking for elevated to possibly critical fire weather conditions. New fires may have rapid fire spread/extreme fire behavior. Photo-Jeff hall #LAWeather #cawx

Congratulations Xeno-Canto!

There is the fire weather. But north winds then turning offshore suggests we could have a bird filled morning in prime watch sites in San Francisco, and maybe even farther south. The question is where do we go in San Mateo County to look???

Although a La Niña event has yet to be officially classified, there is a respectable cold tongue in the equatorial Pacific! 🌊 The 30-day relative Niño 3.4 Index (-1.02˚C) is now in moderate La Niña territory, lower than the value at this time in 2022 (-0.94˚C) and 2021

What are the dynamics of #hybridisation between the Critically Endangered Balearic shearwater and the closely related Yelkouan shearwater? Check out our new preprint out on bioRxiv where we investigate the causes/consequences of pervasive gene flow between these species.

A massive "bomb cyclone" is set to explode off the U.S. West Coast with hurricane force winds, flooding rains, and enormous mountain snow from Category 5 atmospheric river. Central pressure will fall almost 70 mb / 24 hours reaching 942 mb -- similar to Category 4 hurricane.

This Total Precipitable Water loop over the past 48 hours helps us visualize the atmospheric river impacting California. Note the plume of increased moisture stretching from the subtropics directed at the Golden State.🌧️ #CAwx #CArain Images courtesy of UW-Madison CIMSS.
