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.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Thursday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s partly cloudy here in Maui County this morning….with some cloudy areas.  The low temperature at my place was 58 degrees.

It was quite cloudy upcountry, while sunny to partly cloudy conditions prevailed down closer to the beaches.

Hawaii’s Broad Brush Weather Overview:  High pressure far north and northeast of the state will maintain moderate to locally breezy trades through Friday, with winds starting to weaken by the weekend. Expect to see fairly typical summertime weather into next week, as clouds and showers favor windward and mountain areas.

Hawaii’s Weather Details: A surface high remains well north and northeast of the Hawaiian Islands, with moderate to locally breezy trades blowing across the state. Satellite imagery continues to show clouds moving into windward areas, with a band of moisture moving towards Maui County. Radar imagery shows some enhanced showers embedded in this moisture, that is currently moving into Molokai. Expect this band of moisture to shift towards Oahu and Kauai tonight, bringing a slight increase in clouds and showers. Otherwise, expect fairly typical summertime conditions tonight.

Guidance continues to show the high slowly drifting north over the weekend and into next week, with winds weakening a bit starting Saturday. It also shows no organized bands of moisture upstream of the islands, with a fairly typical dry and stable summertime air mass over the region. As such, expect clouds to favor windward areas, with passing showers moving in at times. The Kona Slopes of the Big Island will also continue to see the typical summertime afternoon showers as the sea breeze develops across leeward Big Island.

The one wrinkle to the forecast will be the evolution of an upper level disturbance to the north of the islands. This disturbance could help to enhance instability over the western half of the state, which could bring some enhanced showers this weekend into early next week.

Fire weather: Moderate to locally breezy trades will continue through Friday, then weaken slightly over the weekend into next week. Afternoon relative humidity remains near summertime norms, with fairly typical fire weather conditions expected.

Hawaii’s Marine Environment:  High pressure far northeast of the waters will generate moderate to locally strong trade winds. The Small Craft Advisory that is in effect for the typical windy waters around Maui County and Big Island has been extended through Friday afternoon. Trades may slightly weaken early next week as the high moves further away to the north.

The recent small, long period south swell will continue its decline. A reinforcing longer period south swell is scheduled to arrive Friday night. This minor boost, in tandem with another small, long period south swell arriving Sunday night into Monday, will hold south-facing shore surf to summer averages. East-facing shore surf will remain rough as moderate to fresh trades blow the remainder of the week. A very small northwest swell, originating behind a cold front hanging up far northwest of the islands, may pass through early next week.

Interesting:  Underestimated Sources of Marine Pollution

A study published in Nature reveals for the first time the extent to which nanoplastic pollutes the North Atlantic.Plastic particles less than one micrometer in size are found across the globe – from the peaks of the Alps to the depths of the oceans. A research team from the Helmholtz Centre for Environmental Research (UFZ), Utrecht University, and the Royal Netherlands Institute for Sea Research (NIOZ) investigated the presence of nanoplastic in the North Atlantic.The findings show that nanosized plastic particles are present at all depths between the temperate and subtropical zone of the ocean. By mass, the amount of nanoplastic is comparable to that of microplastic. An article published in Nature concludes that nanoplastic plays a far greater role in marine plastic pollution than previously assumed.Plastic waste pollutes oceans across all regions of the world. Marine animals may become entangled in larger plastic debris such as nets and bags or mistake smaller pieces for food. Ingested plastic can block or injure the gastrointestinal tract. The smallest plastic particles in the micro and nano range are mostly excreted, but a small proportion can pass through the intestinal wall and enter the bloodstream.Read more at: Helmholtz Centre for Environmental Research – UFZ
