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 Monday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s partly cloudy here in Maui County this morning. The low temperature here at my place was 53 degrees.

The high Cirrus clouds lit up a wonderfully beautiful pink color near sunrise!

1105am, sunny skies prevail as we move through this Monday morning, and the fire and thick smoke of yesterday are gone…what a relief to have my windows open again!

225pm, it’s another very warm afternoon here in upper Kula, although tempered to some degree by the variable clouds in our local skies over Maui C0unty. The relative humidity here at my Kula weather tower is 54%, with a temperature of 81 degrees. Despite the heat I was able to take my second walk of the day, before I ate lunch. For lunch I had kale salad, with beet, carrot, avocado, cheese and a slice of chicken…plus tomato.

419pm, a mix of high and lower level clouds, and those high cirrus could give us some color around sunset, like they did at sunrise.

740pm, it’s very cloudy here in Maui County, the only showers that I can see from my weather deck
are offshore from Kahului and Spreckelsville to Paia.

Hawaii’s Broad Brush Weather Overview:  Breezy trades will persist through Tuesday, ease slightly Wednesday through Friday, then become breezy again during the weekend. Clouds and showers will be focused over windward and mountain areas through the week, especially during the overnight and early morning hours.

Hawaii’s Weather Details:  Stable June weather will persist through the week, with periods of locally breezy trade winds focusing showers over windward and mountain areas. Broad surface high pressure far north of the state will maintain trades near current strength through at least Tuesday. Winds will ease slightly on Wednesday as the high shifts to the northeast, followed by a likely increase again during the weekend, as the high moves closer to the state.

A mid-level ridge overhead will maintain stable conditions, and pockets of moisture in the trade wind flow will focus showers along windward areas, especially at night. A diffuse band of shallow moisture will pass over the islands and produce a boost in windward showers, with top sites likely receiving over a half inch of rain.

Otherwise, no organized areas of moisture are noted for the next few days. Aside from a few passing showers tonight, leeward areas from Kauai to Maui will be rather dry, and the Kona slopes of the Big Island will continue to experience scattered showers each afternoon. High clouds over the area will dissipate, as an upper-level low to the west of Kauai is pushed away by a strengthening ridge aloft.

Hawaii’s Marine Environment:  A high pressure system north of the state will generate trades through the week. A slight weakening trend in the winds is expected as the high moves eastward. A Small Craft Advisory for the windier waters and channels near Maui and the Big Island goes through 6am Wednesday with a likely extension.

A series of small, long-period, south swells will help boost surf heights along south facing shores though the week. The current south swell will decline over the next couple days, followed by another south swell from Wednesday into Thursday.

Rough and choppy surf along east facing shores will continue this week. Surf will remain nearly flat along north facing shores throughout the forecast period.

Interesting:  Some Plants Make Their Own Pesticide — But at What Cost to the Atmosphere?

A natural alternative to pesticides may be hiding in a misunderstood plant compound — but it could come at an environmental cost.

For years, scientists knew little about isoprene, a natural chemical produced by plants. New Michigan State University research 40 years in the making now sheds light on how this natural chemical can repel insects — and how some plants that don’t normally make isoprene could activate production in times of stress.

Tom Sharkey, a University Distinguished Professor in the Michigan State University-Department of Energy Plant Research Laboratory, the MSU Plant Resilience Institute and Department of Biochemistry and Molecular Biology, has studied isoprene for much of his career. Now, his lab has published findings that could provide a path for engineering plants that are more resilient to environmental change and pest outbreaks.
