Hello everyone, I’ll be on vacation until November 16th, and will return then to begin my daily weather updates.
In my absence, you can find the current weather forecasts for all of the state, by clicking on the individual islands in the upper left hand corner of this page (then click on the maps), located just below where it says Glenn’s Daily Weather Narrative.
All of the satellite images, and the radar image below, will continue to be the most current available.
Down this page, below the images, I’ll keep a travelogue, giving you updates on what’s going on during my vacation.
Aloha, Glenn James
Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (nearly 13,800 feet high) on the Big Island of Hawaii. This webcam is available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars — and the sunrise and sunset too — depending upon weather conditions.
Here’s the latest weather map

October 13th – I’ll be flying out from Maui today, and arriving in San Francisco this evening. I’ll catch the Marin Airporter, taking it north across the Golden Gate Bridge to Marin County. My good friend Bob, who lives in the Sacramento area, will pick me up, and we’ll head over to our friend Linda’s house in the Larkspur area. As you may know, there’s the season’s first big storm arriving along the west coast today. This will be a major weather event, with strong winds and heavy rains. It’s expected to arrive in the SF Bay area this evening, and keep things wet and windy into the weekend. I consider this a favorable weather greeting, which will also bring much needed precipitation to dry California. I’ll get back in touch soon, to let you know how my flight went, and of course how the weather is! Aloha, Glenn
October 14th – Hi again, I’m beginning to finally feel like I’m on vacation now! My friends Linda, Bob and I have been hanging out, and really enjoying each others company. My flight was easy and smooth, and the airporter ride to Marin County went off without a hitch as well. Bob picked me up, and when we got to Linda’s, she had a warm bowl of home made soup waiting for us, along with some fresh bread, and a tasty cheese I brought. Bob popped a bottle of 2013 Stags Leap Artemis Cabernet from Napa Valley, which was delicious. The next morning we went to Tennessee Valley for a hike out to the ocean, and to stretch our legs, before a good breakfast out in Mill Valley. It rained quite a bit that first day, and we sat in front of the fireplace catching up with each other. For dinner we bought some very fresh King Salmon at the local farmers market, and had that with fingerling potatoes, lightly cooked spinach, and a great salad. We popped a bottle of 2012 Silver Oak Cabernet from Alexander Valley, which was excellent! I’ll catch up with you again soon. Glenn
October 15th – This has been another great day, with breakfast out, more hiking, and keeping an eye on this next inbound storm system. Bob had to head back to the Sacramento area, as he had plans with his girlfriend. Linda and I were a little sad to see him go, although I’m hoping to see him one more time before I head back to Maui. This afternoon the wind is really picking up, with increasingly strong gusts. There’s a couple of minor drops falling out of the cloudy skies, although according to radar, the bulk of this incoming rainfall is still offshore at the time of this writing. Linda is gone to an Audubon meeting, and so I’ve finally had some time to sit down and write. We decided to have a lighter dinner tonight, after the rich dinner last night. We have lots of vegetables we’ll cook up, and plate them with some brown rice, and of course a nice salad. Linda enjoys her television, so after dinner we’ll watch some of her favorite programs, which she records earlier. I guess the main thing now, is to experience this big storm, enjoying the wind and rain, while sitting near the warmth of the fireplace. Trust everyone is well and fine this weekend! Aloha, Glenn
October 17th – Today turned out to be a wonderfully sunny day, after the last two cloudy and wet days. Don’t get me wrong, I greatly enjoyed the inclement weather conditions. Linda had nowhere to go yesterday, so we stayed home all day, and just hunkered in. We had a fire in her fireplace all day, which was a special treat for me! Today Linda was gone most of the day, so I had many hours to catch up on some reading, take a long walk, and do some outside work that Linda suggested. As many of you know, I don’t have a TV, and haven’t had one for many years. Although, I enjoy watching the programs that Linda has recorded, and most evenings after dinner, we sit and watch a couple of fun things. Back to the weather briefly, here in northern California, the recent rainfall is now done, with nothing expected through the next week. Looking ahead, as I fly down to see my Mom in Southern California Wednesday, there’s Santa Ana wind conditions expected. The temperatures are expected to get up into the L90’s for 2-3 days, oh well, I suppose I can manage that. I much prefer cool weather however, which is why I live in upper Kula on Maui.
October 18th – Let’s start off with the weather here in northern California, and its perfect! The low temperature this morning was 44F degrees, and the high this afternoon is in the lower 70’s, under mostly sunny skies. This morning Linda and I joined with two other lady friends of ours, for a 20 minute drive down to Green Gulch, to see the grounds. This place is very near the coast, and after hearing about it all these years, was wonderful to actually visit. We walked down to the beach, and found sunny skies and large waves breaking. I had a shirt on, and was glad I didn’t need my jacket, like is so often required along this cold water coast. We’re back at Linda’s now, and after a really nice large Kale salad, we plan to take a break, and then do a little work a bit later this afternoon. For dinner we bought a nice piece of wild caught, local Rock Cod, which we’ll plate with steamed Broccoli, Zucchini, and a few roasted potatoes. We’ll have this fine food along with a glass of 2013 Murphy-Goode Cabernet Sauvignon. Dessert will be a little container of fine chocolate we got, sort of whipped somehow, called Pot De Creme, followed by a cup of lemon grass tea and a little television.

Interesting: Modeling Floods That Formed Canyons on Earth and Mars – Geomorphologists who study Earth’s surface features and the processes that formed them have long been interested in how floods, in particular catastrophic outbursts that occur when a glacial lake ice dam bursts, for example, can change a planet’s surface, not only on Earth but on Mars.
Now geoscience researchers Isaac Larsen at the University of Massachusetts Amherst and Michael Lamb at the California Institute of Technology have proposed and tested a new model of canyon-forming floods which suggests that deep canyons can be formed in bedrock by significantly less water than previously thought. They point out that “reconstructing the magnitude of the canyon-forming floods is essential for understanding how floods modify planetary surfaces, the hydrology of early Mars, and abrupt climate change.”
Larsen and Lamb apply their new model to the “channeled scablands” in eastern Washington State, an area that, like some on Mars, has very deep canyons cut into fractured basalt bedrock. The researchers say their results suggest “there may be a rich imprint of both the history and discharge of flooding in the morphology of canyons” such as terraces, valley shapes and slope profiles on Earth and on Mars “that warrant further investigation.” Details appear in the current issue of Nature.
The researchers say channels in the scablands today, which are up to 650 feet (200 meters) deep and 3 miles (5 km) wide, were likely formed by flood discharges five- to tenfold smaller than brimful estimates, that is by “significantly lower megaflood discharges than previously thought. The channeled scablands are a classic landscape in the history of geomorphology and we’re bringing new views of how it was formed.”
Until the 1920s, scientists did not understand what could have formed the tortured landscape of eastern Washington studied for decades by J Harlen Bretz, a giant figure in geosciences, Larsen recalls. Bretz was the first to suggest that they were formed by catastrophic flooding of unknown origin. His views were dismissed for years, but Bretz was later vindicated when glacial Lake Missoula was identified as the floodwater source.
As most scientists came to accept the catastrophic flood explanation for the canyons and then tried to estimate floodwater discharges, they assumed that floods filled canyons to the brim, a huge amount of water. But an alternate hypothesis proposed and now tested by Lamb and and Larsen posits that as floodwater cuts into bedrock, the canyon deepens, meaning less water is required to shape it.
In areas underlain by fractured bedrock, Larsen says, “our general concept is that the channel floor was being cut and lowered as the floods were happening, and you need to account for that when reconstructing the scenario of flood magnitude. This applies to the scablands, to Mars and other areas where there have been catastrophic outburst floods.”
He and Lamb combine numerical flood models with estimates of the force required to erode basalt bedrock to show that for Moses Coulee, a canyon carved by catastrophic Lake Missoula floods in eastern Washington when an ice dam repeatedly broke and reformed around 15,000 years ago, their “threshold shear stress model” explains the shape and depth of currently observed channels better than the brimful model.
“We numerically routed floods through the canyon in different states, from current configuration and at four different past scenarios,” Larsen notes. “We predicted the discharge from two models and tested which one is most reasonable, based on the depositional evidence from the current bars seen today in the canyons. The size of floods our model predicts from the basalt erosion better match locations of depositional flood bars in the canyon than the brimful model predicts.”
Larsen and Lamb’s new model also works better to explain observed canyon-cutting mechanics and outflow channels observed on Mars, they point out, “supporting the notion of a multi-flood or low-magnitude flood origin for the Mars outflow channels. ” Larsen adds, “There are very similar but larger canyons on the surface of Mars. These outflow channels are much bigger than the ones on Earth, but they look very similar and the assumption is they formed by similar processes. We know in most cases there were not canyons before these floods happened. They had to be carved, so the bottoms were getting lower and lower with each flood. We believe in the final phases of floods, they were not filled to the brim.”
