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 Aloha Friday comments:  I’m here in Corte Madera, Marin County, California, at my friend Linda’s on a working vacation.

I spoke with a friend who works at the NWS forecast office in Honolulu, and he said that there are major software and personnel changes going on now, some missing weather information for the time being!

Linda and I played Pickleball this morning in Mill Valley…two straight hours! PB is a very active sport, and you really get to stretch your body in all kinds of ways! The weather today is cloudy and cool, with more of the same coming up.

Just before sunset the skies are cloudy, with no rain, although apparently by Sunday we have a 40% chance of some showers in the SF Bay area.

Weather Wit of the day:  Slippery Roads – Something which can give you an auto-body experience

 

Hawaii’s Broad Brush Weather Overview:  Winds will weaken this weekend, with land and sea breezes becoming dominant. A disturbance aloft could bring some unsettled weather and locally heavy rainfall to the islands early next week. A return to more typical trade wind weather featuring mainly windward and mountain showers may return during the latter part of next week.

Hawaii’s Weather Details:  A surface low is centered northwest of Kauai, while a high is centered around 1500 miles north-northeast of Honolulu. Between these two features lies a band of thunderstorms along a trough of low pressure stemming from the low, which passes around 150 miles northwest of Kauai.

Visible satellite shows thin cirrus clouds tracking across the main Hawaiian Islands. At the low levels, moderate southeast flow across the state are pushing a few clouds with isolated showers onto windward and southeast slopes, but overall mostly dry conditions expected through night. A slight chance of thunderstorms possible tonight for waters north and west of Kauai along the eastern fringes of the trough, but stability is expected to increase this weekend.

The surface low will shift eastward this weekend, then turn into a trough over the islands early next week. This will ease the east-southeast flow allowing for daytime sea breezes and nighttime land breezes to become dominant across the state this weekend through the middle of next week.

Low clouds and showers will favor leeward and interior sections in the afternoon and evening hours, and east and southeast facing slopes and coasts overnight and during the morning hours, with most showers over the coastal waters or near the immediate coast overnight. A disturbance aloft moving southward over the state could bring locally heavy rainfall to portions of the island chain Tuesday into Wednesday.

The trough will then fizzle out with a gradual return and strengthening of the trade winds across the state for the second half of next week, featuring mainly windward and mountain showers.

Hawaii’s Marine Environment:  Locally fresh southeast winds will persist through Saturday, as a trough remains nearly stationary northwest of the islands. Light flow Sunday through Tuesday will transition to a typical trade wind pattern around the middle of next week.

Existing small northwest swell will continue to fade providing tiny surf for north and west facing shores. A slightly larger long-period northwest swell is forecast to build on Saturday, peak Saturday night into Sunday, then fade through early next week. Surf should still remain well below advisory thresholds for north and west facing shores.

An ongoing small, medium to long period, south swell will slowly decline, with mainly small background south swell energy continuing into the weekend. A lack of upstream trades will favor near to below average surf along east facing shores.

Interesting:  Newborns Living Near Trees Tend to Be Healthier. New Data Suggests It’s Not Because Healthier People Reside Near Parks

The link between proximity to greenspace — including trees and parks— and healthy birth outcomes is well established. Now new data from researchers at Drexel University’s Dornsife School of Public Health adds to our understanding of these health benefits, accounting for other factors that may influence this link, such as education, income and body mass index, but also taking the body of knowledge a step further by exploring the effect of residing near newly planted trees. The findings were recently published in the journal Science of The Total Environment.

Using a unique dataset — the planting of more than 36,000 trees between 1990 and 2020 in Portland, Oregon by the nonprofit group Friends of Trees — the researchers measured the number of new trees planted within 100 meters of a mother’s address for the first 10 years after their child’s birth, (using Jan. 1, 2015 – Dec. 31, 2020 birth data from the Oregon Health Authority), existing tree cover and road coverage in that area.

Controlling for factors that can influence birth weight, such as mother’s race, whether they’re pregnant for the first time, mother’s BMI and education level, the researchers found a link between number of trees planted and higher birth weight. Additionally, nearby tree planting, including new and existing trees, were associated with three key measures of newborn health: higher birth weight, lower risk of small-for-gestational-age birth and decreased risk of pre-term birth.
