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 Saturday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s clear here in upper Kula early this morning, although with volcanic haze still around, while my low temperature was 49.5 degrees.

Weather Wit of the day:  Familiar Sunset – Deja view

 

Hawaii’s Broad Brush Weather Overview:  Light southerly winds will occur over the western half of the state, while southeasterlies continue across the eastern half of the islands. The best chances for weekend showers will focus over leeward areas and higher elevations. Trade winds will return early next week, and produce a more wet pattern as they strengthen into Tuesday. There will be a higher frequency for showers to pass over more windward-facing exposures.

Hawaii’s Weather Details:  A warm front a few hundred miles north of the islands will wash out, as the next front from the west quickly fills in behind it. This slowing front will encounter mid to upper ridging that is centered across and east of the islands. The position of the surface ridge will continue to promote gentle southerly winds over the western islands, and southeasterly breezes across the eastern half of the state.

With little change in the Central Pacific weather pattern, dry weather will be the theme this weekend. The western half of the state will experience more cloud cover and shower activity over leeward areas, within this southern flow the next couple of days. The southeasterly flow will generate more cloud build ups, and frequent showers that will favor southeast facing coasts and the mountain slopes of Maui County and Big Island.

The surface ridge southwest of high pressure centered far northeast of the area, will remain draped over the islands as mid to upper level ridging builds in overhead. Warm and muggy conditions will hang on for another day or so, as this gentle southerly flow maintains elevated afternoon humidity levels.

While this weak front passes north of the state, it will provide minor fluctuations in overall wind behavior, a general southern wind pattern will remain in place through Sunday. Rainfall accumulation will be very minimal as mid-level ridging provides subsidence, in tandem with a relatively dry air mass, to keep the lid on any significant shower activity this weekend.

A new front approaching from the northwest early next week will likely dissipate just before it reaches the state. Strong ridging at all levels will expand in north of the state. A large surface high moving to the east, north of the chain, will be the impetus of returning breezy to locally windy trade winds from Monday through the remainder of next week.

Overall, rainfall accumulations will be minimal the next several days due to a combination of subsidence from mid-level ridging building in from the west, and drier air filtering across the area helping to put a damper on shower activity. Higher moisture being carried in on well-established trades will increase the probabilities of a wetter trade wind pattern late next week.

Imagery, surface and air quality observations show vog continuing to impact the majority of the state from Big Island to Oahu. SO2 emissions from areas of Kilauea’s Halema’uma’u crater are being caught up and transported within the south-southeast lower level winds. As trades build back in early next week, any lingering upstream vog will be carried westward across the islands. Vog concentrations will likely thin out as strengthening trades better mix out haze.

Hawaii’s Marine Environment:  A ridge of high pressure over the islands, will slowly lift northward and weaken tonight and Sunday, as a front approaches from the west. Light to moderate southerly winds will prevail over the western islands, while moderate east-southeast winds hold over the eastern end of the state. The front will stall and weaken into a trough west of the islands Sunday and Sunday night, allowing trade winds to gradually fill in and strengthen. A new high building north of the state early next week, will bring strong trade winds back to the island chain, which will continue through late next week. A Small Craft Advisory will likely be needed for winds across a large portion of the marine area much of next week.

The current large northwest swell continues to decline, and surf heights have lowered below warning levels. This swell will continue to gradually decline through the remainder of the weekend.

A new moderate to large northwest swell is due in early next week, which could bring another round of advisory level surf to most north and west facing shores late Monday through Tuesday. This swell will then gradually lower through Thursday, with a new large northwest swell possibly bringing another round of advisory level surf to north and west facing shores late next week.

Surf along south facing shores will remain very small through late next week. Surf along east facing shores will remain very small through the weekend. East shore surf will begin to rise with the returning trades Sunday night and Monday, with surf rising to above normal levels Tuesday through late next week.

Interesting:  Influencer Marketing Can Help Tourism Industry Mitigate Waste, Pollution

Social media influencers who are passionate about environmental causes can help the tourism industry inspire tourists to engage in pro-environmental behavior to help mitigate waste and pollution, according to a new study from researchers in the Penn State School of Hospitality Management.

The research team found that influencers who are highly passionate about sustainability lifestyles — coined “green influencers” — can increase tourists’ environmental support through social media messaging. The researchers also found that environmental support, or backing waste reduction and wildlife conservation efforts, can be passed along to tourists via social media when influencers display less passion but do convey strong, specific goals.

Led by Penn State Assistant Professor of Hospitality Management Anni Ding, the research team published its findings in the Journal of Sustainable Tourism.
