Have you heard? The country’s first electric tugboat, displacing 30,000 gallons of diesel fuel per year, is operating in the Port of San Diego! The community, long impacted by local pollution, has made major strides to reduce emissions.

Tropical moisture from Priscilla and Raymond bombarded the desert Southwest over the last few days, leading to many instances of flash flooding.
There is a slight risk of excessive rainfall for the area today.

Arrived at Salt Lake City late afternoon today, partly sunny but with all the harbingers of a storm coming. Within 2 hours, the cold front swept through with strong gusts, lightning, and torrential downpours.

Dendrochronologist check-in at Lowman, ID. This tree has beautiful complacent rings, which date back to 1732 (year when George Washington was born) and through 2016 when the Pioneer Fire in Boise National Forest burned 188k acres.

Rare lightning storm lights up San Francisco sky
California was hit by thousands of lightning strikes from Tuesday to Thursday, including parts of the Bay Area that average fewer lightning strikes than nearly anywhere else in the country.

The lightning-sparked Garnet Fire in California’s Sierra National Forest is burning through part of a giant sequoias grove. Some of the trees are 3,000 years old.

What a delightful treat to see virga in July: (1) last night at sunset, Roseville actually saw a few raindrops on the ground; (2) this morning’s sunrise lighting at just the right angle, creating a nice visual.

It's been a bit since I've done a meteorological deep dive, but the devastating flash #flood in central Texas this July 4th/5th deserve a closer look. #TXwx
Yes remnants of #Barry were involved helping enhance moisture. A remnant MCV from Mexico on 3 July also played a role.
