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 in Bend, Oregon with my friend Bob Earle.

It’s mostly clear here in Bend early this morning. The low temperature was a very chilly 23.5 degrees.

Around mid-day here in Bend, I just sat out on the edge of the Deschutes River and enjoyed the warm sunshine, even though the air temperature is a cool 48.7 degrees. I especially enjoy watching all the Canadian Geese as they cruise by both swimming and in the air.

We walked to a place and had a pasta dinner, which was alright. Now, with the time change, it feels like 9pm, and it’s only 7pm. The temperature here at our place on the river is 31.4 degrees (that’s cold for this Maui boy!)

513pm Hawaii time, there’s some heavy to very heavy showers falling in the vicinity of Kauai…and to a lesser extent Oahu and even Molokai.

838pm here in Bend, the temperature has fallen to a chilly 27.1 degrees under clear skies…with a growing large moon.

Hawaii’s Broad Brush Weather Overview: An upper low and surface trough to the west will slide further to the west allowing trades to build in. An area of tropical moisture will clip the Big Island Monday and Monday night, and bring showers to windward and southeast slopes. A cold front will approach the islands next weekend.

Hawaii’s Weather Details: Satellite imagery shows an upper low just west of the state digging towards the south-southwest. This low is reflected at the surface as a trough with the axis passing just north of Kauai. Moderate east-southeast winds encompass the state with the trough separating strong northeast winds just offshore of the north and west sides of Kauai.

The trough will move west tonight and winds will back easterly by Monday. Moderate trades will begin to usher in drier air across the smaller islands. The northern edge of a band of tropical moisture will clip the Big Island Monday and Monday night. Cloud tops may briefly reach the highest summits of Mauna Kea and Mauna Loa on Monday and Monday night bringing a chance for freezing rain. Rain chances also increase across windward and southeast Big Island low elevations.

Models continue to show a weak ridge filling in aloft over the state with a decrease in showers Tuesday through Thursday. An upper level trough moves in from the northwest on Friday, divergence aloft will spread over the islands lifting trade wind temperature inversion heights, and increase shower trends from Friday into the weekend. A cold front will approach the islands from the north and stall near Kauai and Oahu next weekend.

Fire weather: Increased relative humidity values and light trades will maintain below critical fire weather conditions the next several days. Temperature inversion heights near the Big Island and Maui will be around 10,000 feet, with unstable conditions on Kauai and Oahu. Expect a gradual return to more stable weather Monday.

Hawaii’s Marine Environment: A front is sagging southward over the northwest portion of the offshore waters, bringing pockets of strong (near gale force) breezes, along with isolated to scattered thunderstorms. Some of these thunderstorms may enter the coastal waters near Kauai through tonight. The front is expected to stall and then get pushed to the west as high pressure builds to the north by Monday, increasing trade winds to moderate to locally fresh speeds.

Winds will likely remain below SCA levels until Tuesday or Wednesday. However, seas are expected to reach SCA levels as a mix of northwest and north swells build into the northwestern end of the island chain. By the later half of the upcoming work week, a front far to the north could disrupt the trade winds once again.

Surf along north facing shores will build as a mix of medium to long period north-northwest swells (320-330 degrees) fill in across the area. A medium period north-northeast swell will fill in tonight associated with the approaching front with near-gale winds, that will primarily impact the western end of the state. This mix of swells is expected to maintain HSA level surf through tonight before gradually fading and so a HSA is in effect through 6am HST Monday for most north and west facing shores of the smaller islands. A moderate long period north-northwest swell (340 degrees) is then possible around the middle of the week.

Surf along east facing shores will remain small to moderate, and then may be impacted by the medium period NNE swell mentioned above. South shore surf will remain small through early in the week, before building slightly mid to late week as a long period south-southwest swell (190 degrees) fills in across the region.

Interesting:  Tricky Treats: Why Pumpkins Accumulate Pollutants

Pumpkins, squash, zucchini and their relatives accumulate soil pollutants in their edible parts. A Kobe University team has now identified the cause, making it possible to both make the produce safer and create plants that clean contaminated soil.

The gourd family of plants comprising pumpkins, zucchini, melons, cucumbers and more are known to accumulate high levels of pollutants in their edible parts. Kobe University agricultural scientist INUI Hideyuki says: “The pollutants don’t easily break down and thus pose a health risk to people who eat the fruit. Interestingly, other plants don’t do this and so I became interested in why this happens in this group specifically.”

In previous studies, the Kobe University researcher and his team identified a class of proteins from across the gourd family that bind to the pollutants, thus enabling them to be transported through the plant. Earlier this year they published that the shape of the proteins and their binding affinity to the pollutants influence the accumulation in the above ground plant parts. “However, these proteins exist in many other plants, and even among the gourds, there are varieties that are more prone to accumulating pollutants than others. We then noticed that in the highly accumulating varieties, there are higher concentrations of the protein in the sap,” says Inui. Thus, his team turned their attention to the secretion of the pollutant-transporting protein into the plant sap.
