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.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Sunday comments:  I’m here at Sea Ranch, CA with my friend Bob.

It’s clear this morning here at the coast, although with some beautiful streaks of high icy cirrus clouds, which lit up a pretty pink at sunrise. The low temperature here was 47.5 degrees.

We’re back from playing Pickleball at the courts here at Sea Ranch, which was fun to meet new people, and play a few games.

Yet another great day on the coast, perfect weather for all manner of outdoor activities! Bob and I sat out on the deck and had a cocktail while watching the everlasting sunset! We were talking today about how long we’ve been best of friends, and realized that it has been 53 years since we met in college.

Hawaii’s Broad Brush Weather Overview: A weakening frontal boundary will continue to move south across the Big Island tonight. Breezy to locally strong trades will persist through much of the week, becoming even stronger by mid-week as strong high pressure builds north of the islands. Typical windward and mountain showers will prevail, with generally drier conditions over leeward areas.

Hawaii’s Weather Details: Radar and satellite imagery show a weakening frontal boundary draped across the Big Island. Clouds and light to brief moderate showers remain focused over windward and mountain areas of Oahu, Molokai, Maui, and the Big Island, with the occasional spillover into leeward areas of the smaller islands. Rainfall totals over the last 6 to 12 hours ranged from 0.20 inches over portions of windward Oahu to over 4 inches along portions of windward Molokai and Maui. Portions of windward Big Island have already received close to 2 inches of rain.

Guidance continues to show a diffuse frontal boundary moving south across the rest of the Big Island tonight. This will bring some much needed rainfall to portions of the Kau District, but mid-level ridging will continue to limit vertical development. Expect slightly drier and more stable conditions to continue post-frontal as high pressure builds north of the state. This slightly drier air mass will bring lower dew points (Dew points: the atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form) to the area, so temperatures will feel cooler than normal over the next couple of days.

Aside from some light and variable winds over portions of southeast Big Island, recent observations show breezy to locally strong northeast winds have filled in across much of the state. Expect wind speeds to slowly strengthen over the next couple of days, and peak mid-week as strong high pressure builds far north of the state. Based on the latest guidance a wind advisory may be necessary for portions of the state later in the week. Otherwise, windy trades continue through much of the week, with clouds and showers favoring windward and mountain areas under stable conditions.

Fire weather: Critical fire weather conditions not expected the next couple of days. Breezy to locally strong trades will continue across the state through much of the week, but low-level moisture embedded within the trades should help to keep relative humidity from reaching critical thresholds.

Hawaii’s Marine Environment: Rough marine conditions expected through much of the week, due to strong trade winds and a series of north to northeast swells. A cold front currently pushing across the eastern islands. Strong northeast winds will follow in its wake with a quick rise in seas. A Small Craft Advisory remains in effect for many coastal areas, and has been expanded in coverage to include all of the Hawaiian coastal waters starting tonight as the front makes its way through the island chain. Strong northeast winds will persist through much of the upcoming week with an increase expected mid-week, as the high strengthens and builds north of the area Wednesday into Thursday, bringing the possibility of gales for some of our typical windy channels around Maui County and the Big Island.

A moderate, short-medium period, north-northwest to north swell has arrived and will produce elevated surf along north facing shores as it continues to fill in. With the offshore buoys northwest of the state peaking with energy mostly in the 10 to 12 second energy bands yesterday afternoon and evening, we are expecting near borderline advisory level surf along north facing shores.

A larger moderate period north to north-northeast (010-030 degree) swell will fill in tonight into Monday which should exceed advisory thresholds along north and east facing shores. Due to the northerly direction, areas such as west Maui will also see elevated surf as well as some of the exposed areas of west Big Island near Kua Bay. Another reinforcing northeast swell is expected towards the middle of the week, as a gale force low develops northeast of the state on Monday. The combination of these swells will likely produce moderate to heavy surges in north facing harbors such as Kahului and Hilo harbors throughout the first half of the week.

A small, long period, south-southwest swell will keep surf heights near seasonal averages along south facing shores. Then a pair of south to south-southwest swells should bring above average surf throughout the first half of the week.

Peak monthly tides combined with water levels that are running higher than predicted will lead to minor flooding along the shoreline and in low-lying coastal areas during the morning high tide.

Interesting:  Climate Intervention Techniques Could Reduce the Nutritional Value of Crops, New Study Finds

A new study published in the journal, Environmental Research Letters, reports that cooling the planet by injecting sulfur dioxide into the stratosphere—a proposed climate intervention technique—could reduce the nutritional value of the world’s crops.

Scientists at Rutgers University used global climate and crop models to estimate how stratospheric aerosol intervention (SAI), one type of solar geoengineering, would impact the protein level of the world’s four major food crops, maize, rice, wheat and soybeans. The SAI approach, inspired by volcanic eruptions, would involve releasing sulfur dioxide into the stratosphere. This gas would transform into sulfuric acid particles, forming a persistent cloud in the upper atmosphere that reflects a small part of the Sun’s radiation, thereby cooling the Earth.

While these cereal crops are primarily sources of carbohydrates, they also provide a substantial share of dietary protein for large portions of the global population. Model simulations suggested that increased CO2 concentrations tended to reduce the protein content of all four crops, while increased temperatures tended to increase the protein content of crops. Because SAI would stop temperatures from increasing, the CO2 effect would not be countered by warming, and protein would decrease relative to a warmer world without SAI.
