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 Tuesday comments:  I’m here in Corte Madera, California, visiting my friend Linda, at the start of a working vacation.

Weather Wit of the day:  Rainmaker – A storm seller

 

Hawaii’s Broad Brush Weather Overview:  Rain chances will steadily increase through the week, as a cold front and upper-level disturbance draws moisture northward into the islands. The front is expected to move over Kauai late Wednesday into Thursday, before stalling near Oahu. A wet trade wind pattern looks to return by the weekend, then dry out early next week.

Hawaii’s Weather Details:  Weather maps show a gale low northwest of the state slowly moving east. An associated cold front is northwest of Kauai. Meanwhile, satellite imagery shows a mix of upper and low level clouds streaming over the western end of the state, with the eastern end of the state mostly clear.

Radar shows some scattered light to moderate showers developing south of the central islands, and we can expect these showers to continue to move northward embedded in the southerly flow. Voggy conditions and rather humid conditions will continue through much of the week.

The gale low is on track to move northeast, and the associated cold front will slowly shift southeast towards the state. This setup is allowing for moderate southerly winds to hold. Winds look to gradually ease on Wednesday and Thursday, as a deep moisture axis and frontal boundary approaches and moves over Kauai.

The front is expected to stall and weaken across the western end of the state Friday. The moisture band ahead of the front, combined with broad instability, will support more widespread showers later this week, especially across Kauai and Oahu.

Breezy trade winds look to fill in behind the front late Friday into the weekend as the front dissipates. Lingering moisture will keep chances of rainfall high mostly along windward areas, with a few showers spilling over into leeward areas on occasion. A drier, more typical breezy trade wind pattern shall return next week.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Vog map animation

Hawaii’s Marine Environment:  A frontal system, slowly approaching the state from the distant northwest, will help maintain moderate to locally breezy southerly flow across the local waters. Localized terrain enhancement around the Big Island and Kauai will continue to result in advisory level winds, and a Small Craft Advisory (SCA) remains in effect for waters around Kauai, and through Wednesday morning for waters around the Big Island.

The winds will gradually ease Wednesday and Thursday as the aforementioned front weakens and nears the islands. As the front pushes southeast and dissipates across the smaller islands Friday through the weekend, moderate to locally strong northeast trades will begin to ramp-up.

A series of small overlapping north and northwest swells will keep some surf in place along exposed north and east facing shores through late Wednesday. The presence of a small, medium period, northerly swell can already be noted on the near shore buoys. Another small northwest swell of similar size and period will also affect the waters.

A moderate north-northwest (310-330) swell should arrive on Friday and could produce advisory level surf. A large to extra large, long period, north to north-north west (340-360) swell is forecast to arrive this weekend and would likely produce warning level surf along north and possibly west and east facing shores. This swell, aside from being hazardous to small craft, could generate harbor surges along north facing bays and inlets.

Surf along south facing shores will gradually lower over the next day or two, with mainly background energy by the second half of the week.

Interesting:  Rice Scientists Pioneer Method to Tackle ‘Forever Chemicals’

Rice University researchers have developed an innovative solution to a pressing environmental challenge: removing and destroying per- and polyfluoroalkyl substances (PFAS), commonly called “forever chemicals.” A study led by James Tour, the T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering, and graduate student Phelecia Scotland unveils a method that not only eliminates PFAS from water systems but also transforms waste into high-value graphene, offering a cost-effective and sustainable approach to environmental remediation. This research was published March 31 in Nature Water.

PFAS are synthetic compounds in various consumer products, valued for their heat, water and oil resistance. However, their chemical stability has made them persistent in the environment, contaminating water supplies and posing significant health risks, including cancer and immune system disruptions. Traditional methods of PFAS disposal are costly, energy-intensive and often generate secondary pollutants, prompting the need for innovative solutions that are more efficient and environmentally friendly.

“Our method doesn’t just destroy these hazardous chemicals; it turns waste into something of value,” Tour said. “By upcycling the spent carbon into graphene, we’ve created a process that’s not only environmentally beneficial but also economically viable, helping to offset the costs of remediation.”
