Hawaii’s MountainsHere’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 Sunday comments:  I’m here at home in upper Kula, Maui

It’s mostly clear with a few high and low clouds here in Maui County early this morning, with a chilly low temperature of 49 degrees at my place, with the relative humidity 71 percent.

555am, it’s still dark so I can’t see if there’s any vog yet, although it wouldn’t be surprising.

Hawaii’s Broad Brush Weather Overview: Mainly scattered showers will continue for the next several days over most islands. Leeward showers will form in areas sheltered from southeast surface winds. Increasing instability aloft, along with a band of moisture, are expected to keep showers in the forecast through the middle of the upcoming week. Trades are expected to return late Wednesday into Thursday, with drier air moving in Friday and lasting into next weekend.

Hawaii’s Weather Details: The cold front that has been slowly moving toward the islands from the west will reach its closest point today, stall, then start to recede back to the west tonight. The band of moisture associated with the decaying front will be picked up by the leading edge of northeast winds building southward toward the state, as a surface high strengthens Wednesday into Thursday.

The band, which extends well northeast of the area, will pivot clockwise and pass over the island from the northeast Thursday night and Friday. After this, much drier low-level air is forecast to flow out of the northeast and into the area for next weekend.

Southeast surface winds will continue through roughly Wednesday, replaced by east to northeast trades Wednesday night into Thursday. Today through Wednesday, we will see continued land and sea breezes along with the typical afternoon and evening maximum in convection in leeward areas sheltered from the southeast winds.

Otherwise, we will see a few windward and mountain showers, with what is typically considered “windward” shifted a little south from its usual, meaning owing to the southeast winds. Once the surface winds change to northeast, windward showers will be in their usual locations, and land and sea breezes will diminish.

The latest guidance indicates some changes in the flow aloft. We start today with weak southwest flow aloft. This weakens further through Tuesday, after which a very small upper level low forms overhead. This will bring slightly cooler temperatures aloft, and lead to an increase in instability. We will likely see an increase in showers Tuesday and Wednesday.

By Thursday into Friday, a significant upper level low drops southward well to our west, inducing a ridge to develop just to our west. This will bring northwest flow aloft over the islands. The proximity of the ridge means warmer temperatures aloft, and this decreases the instability, and therefore the number and strength of showers.

Hawaii’s Marine Environment: A front will stall west of the state and keep a surface ridge near Kauai. This should allow gentle to moderate southeast to south winds to persist across most waters, and locally fresh east to southeast winds around Big Island. The ridge will retreat northward Monday, allowing east to southeast winds to develop across the island chain.

Easterly trade winds will strengthen Tuesday and Wednesday as broad high pressure builds to the north, and a Small Craft Advisory (SCA) will likely be needed for the typical windy waters around Maui County and the Big Island. SCA conditions may expand to additional waters Thursday as high pressure builds north of the region.

A small, medium period, west-northwest (290-310 degree) swell will hold and bring small, below average, surf to north facing beaches. A larger, medium period, northwest (330-340 degrees) swell will build through Monday, producing surf near the High Surf Advisory level along north and west facing shores. A slightly larger pulse of overlapping long period north-northwest swell will build Monday night and will likely push surf above the advisory level by Tuesday. Resulting seas may reach the SCA threshold across exposed waters during the peak of the swell. This swell will gradually decline through the remainder of the week.

Small surf will prevail along east facing shores due to a lack of trade winds. A slight increase in choppy east shore surf is expected late Monday though mid-week as trade winds rebuild. Surf along south facing shores will remain tiny to small through the forecast period

Interesting: Gold Particles and Sunlight Can Help Purify Water

Industrial waste, dyes and chemicals all potentially pollute our waters. This is a problem we have to address, but how can water be cleansed of these pollutants in a sustainable manner?

Jibin Antony, a PhD research fellow at NTNU’s Department of Chemical Engineering believes the solution may lie in using something of which we have in great abundance: sunlight.

“We need technologies that are green, affordable and efficient. The sun provides us with an enormous amount of energy, completely free of charge. The challenge is finding materials that can use sunlight to break down pollutants in water,” Antony said.
