Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are 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.

Glenn’s Tuesday comments:  I’m here in Corte Madera (Marin County, CA) at my friend Linda’s place

It’s cloudy with fog and a light mist early this morning…with a low temperature of 35.5 degrees.

The morning clouds were slow to burn off until the mid-afternoon here in Corte Madera, and already at 406pm (PST), they are already returning.

Hawaii’s Broad Brush Weather Overview: Light winds will give rise to expanding daytime sea breezes and gentle overnight land breezes. Little rainfall anticipated for the next several days.

Hawaii’s Weather Details: Moderate ESE winds and mostly clear skies prevail area wide courtesy of a dry resident airmass, and a strong inversion that slopes from around 4,000 feet at Lihue to 6,000 feet at Hilo. Dry weather continues for the next week, as the trade wind belt remains weakened and suppressed to the south, courtesy of a relatively lower latitude storm track across the north Pacific.

With little change during the next week, the local gradient will remain light with daytime sea breezes and overnight land breezes, particularly over the smaller islands. A relative lack of low-level moisture leaves little to work with, so expect nothing more than modest afternoon cloud build ups over island interiors, and spotty light showers during this time.

Fire weather:  Wind and humidity levels remain below critical fire weather thresholds this week. Limited showers during this time.

Hawaii’s Marine Environment: A ridge of high pressure north of the state will gradually weaken and drift south over the islands Wednesday. This will cause our current moderate to locally fresh easterly trade winds to gradually weaken over the next several days, and veer from the southeast direction. The forecast beyond Thursday will be highly dependent on the evolution of a large North Pacific storm developing Thursday into Friday.

Latest global models and its ensemble members are in line with a cold front approaching the state from the northwest Friday into Saturday, with the front stalling and weakening within the vicinity of Kauai Saturday into Sunday.

Although the details remain uncertain regarding thunderstorm chances, confidence is increasing for large seas building above the Small Craft Advisory (SCA) thresholds this week. The first round of high seas will build in from Wednesday through Friday, and then another round of SCA conditions with the second larger northwest swell builds into the region Saturday afternoon into Sunday.

The current northwest swell will continue to decline. A large long period northwest (320-330 degree) swell will fill in Wednesday, likely exceeding advisory thresholds through Thursday. This northwest swell could briefly approach warning thresholds late Wednesday night into Thursday morning.

A large storm force low is expected to develop across the West Central Pacific on Thursday, and could send our first extra large northwest swell of the season into the islands from Saturday night into Sunday, affecting exposed north and west facing shores. There are still some differences regarding the intensity of the low with each model run, but nonetheless we should see an extra large swell by Sunday. Expect a higher degree of uncertainty on the final size of this next swell, as the size of the low and the close proximity of the fetch leaves some potential for even giant size surf affecting north and west facing shores by Sunday.

Surf along east facing shores will remain small through the week due to the lighter winds.

Interesting: What’s Happening to Our Food?

Several UC San Diego-led projects take a closer look at the safety and sustainability of seafood.

If you spend any time in San Diego, you know seafood anchors the local culinary scene. From Baja-inspired fish tacos and artfully prepared sushi to hearty surf-and-turf plates and fresh market catches, the options are endless.

Beyond its West Coast flavor, seafood also delivers a major economic kick. According to the most recent National Oceanic and Atmospheric Administration’s fisheries report, commercial and recreational fisheries in the U.S. generate an estimated $321 billion in sales annually and support roughly 1.7 million jobs. Seafood also offers numerous health benefits, serving as a heart-healthy source of lean protein, particularly species such as anchovies, mackerel and herring that are rich in omega-3 fatty acids.

Yet the vital seafood industry faces threats from pollutants, parasites and environmental changes that put both marine life and humans at risk. So, what’s happening to our food — especially our seafood — and how concerned should consumers be?
