Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. 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 at my friend Linda’s place in Corte Madera, CA

Good day everyone, I hope you have a great Tuesday wherever you happen to be spending it.

421am, it’s a clear morning, with a low temperature of 45 degrees.

 

Hawaii’s Broad Brush Weather Overview:  Moderate trades will prevail over the eastern islands through mid-week, while lighter trades over the western end of the state allow for some leeward land and sea breezes. Relatively dry weather will persist through Wednesday, with a few showers affecting windward areas overnight into the early morning hours and developing over interior and leeward areas each afternoon.

Moderate to locally breezy trade winds will return Wednesday night and Thursday, bringing a transition over to more typical trade wind weather. The trades will become breezy Thursday night through early next week, and the trade wind showers will likely increase in coverage and intensity as a disturbance aloft moves over the islands.

Hawaii’s Weather Details: Weather maps show a weak trough of low pressure not far northwest of Kauai, while a high is centered far northeast of Hawaii. Moderate trade winds prevail over the eastern islands, while lighter trades remain over the western end of the state.

Satellite imagery shows a mix of high and low level clouds, resulting in partly to mostly cloudy conditions across the island chain. Radar imagery shows isolated to scattered passing rain showers moving into windward areas, with mainly dry conditions in leeward communities.

A weak trough of low pressure northwest of the islands will remain nearly stationary, with little change expected in the overall wind conditions. Moderate trades will hold over the eastern end of the state, while lighter trades prevail over the western islands, allowing for leeward sea and land breezes.

We should see the trades start to rebound tonight and Wednesday, as the trough west begins to shift slowly westward. Moderate to locally breezy trades should overspread the island chain Wednesday night and Thursday, with breezy conditions expected Thursday night through early next week, as a pair of highs consolidate to the distant north.

Meanwhile, relatively dry conditions should generally prevail across the island chain through Wednesday. Brief passing showers will be possible in windward areas overnight into the early morning hours, with a few showers developing over interior and leeward areas each afternoon.

We should transition over to a more typical windward focused trade wind pattern Wednesday night and Thursday, with wetter trade wind conditions looking more likely to develop Friday through early next week, as upper troughing sets up over the state, and gradually becomes an upper low in the vicinity of the islands.

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

Marine Environmental Details: Moderate to fresh trade winds will persist as high pressure remains far northeast of the area, and a trough holds in place northwest of Kauai. Trade winds look to strengthen into the moderate to locally strong range, as high pressure will build far north of the state through the rest of the week.

A Small Craft Advisory will likely initially be issued for the typical windy waters around the Big Island and Maui, and may be expanded to additional waters Friday or Saturday, as the high pressure system north of the state of Hawaii strengthens.

Tiny surf will persist along north facing shores through Friday, with a small pulse of northwest swell expected this weekend. A small south-southwest swell will peak, and slowly ease Wednesday. Otherwise, look for small surf on south shores for the rest of the week.

Choppy surf along east facing shores will decline over the next couple of days, then gradually increase as trade winds rebuild. Rough east shore surf will likely rise above seasonal average Friday into the weekend.

Interesting: Deer Are Expanding North, and That’s Not Good for Caribou

 

As the climate changes, animals are doing what they can to adapt.

Researchers from UBC Okanagan—which includes partners from Biodiversity Pathways’ Wildlife Science Centre, the Alberta Biodiversity Monitoring Institute, the University of Alberta, and Environment and Climate Change Canada—wanted to evaluate why deer densities in the boreal forest are rapidly increasing.

Over the past century, white-tailed deer have greatly expanded their range in North America, explains Melanie Dickie, a doctoral student with UBC Okanagan’s Wildlife Restoration Ecology Lab.

In the boreal forest of Western Canada, researchers have considered that both changing climate and increased habitat alteration have enabled deer to push farther north. Climate change can create milder winters, while habitat alteration from forestry and energy exploration creates new food sources for deer.
