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.

Glenn’s Monday comments:  I’m here at home in upper Kula, Maui

528am Monday morning, with calm conditions, with cloudy skies here at my place, with the low temperature 59.5 degrees, along with the relative humidity 82%.

831am, thick fog with light sprinkles here at my place in upper Kula, with cooler air arriving for a change…rather than the muggy south and southwest kona winds of late. The temperature at my place is 61.3 degrees. I heard big thunder earlier this morning, but saw no lightning.

910am, still foggy here in upper Kula, with a little mist, nothing like what’s happening over on the windward side of east Maui…where it’s very wet.

1254pm, It’s cloudy with foggy skies, along with calm winds and sprinkles here at my place…at least at the time of this writing. I’m just back from pickleball in Makawao, where it was raining lightly, and in Pukalani too.

630pm, the trade winds are definitely back, as they are reaching Kula as a refreshingly cool breeze. It looks cloudy and wet over along the windward sides as we head into sunset.

811pm, it’s windy here in upper Kula at my place, with the temperature showing 60.6 degrees…and the relative humidity 69%

Hawaii’s Broad Brush Weather Overview…as of 335pm Monday:  The active weather will start to taper off tonight as the triggering upper trough moves east of the state. As trade winds build in and strengthen, numerous windward showers expected Tuesday and Tuesday night before the remnant moisture moves west of the state. Expect drier trade wind weather Wednesday and beyond.

Weather Details for the islands…as of 335pm Monday:  Satellite imagery shows an upper level trough moving across Hawaii, enhancing the band of moisture across the eastern half of the state, left behind by the kona storm. Showers and thunderstorms have triggered on Oahu, Maui and Big Island today, brought on by abundant moisture, and cold temperatures aloft.

The showers and thunderstorms are expected to wane tonight, but given the current active weather on the Big Island, the Flood Watch for Big Island will be active through early Tuesday morning. A Winter Weather Advisory is also posted for an additional 1 to 2 inches of snow on the Big Island summits above 12,000 feet.

The upper trough will slide east of the state tonight with zonal flow expected over the next several days. Trade winds are building in and strengthening, and will reach the Big Island by Tuesday morning. Expect breezy trade winds to continue through Wednesday night, before weakening back to moderate levels.

Windward showers will be numerous across Maui County and the Big Island through Tuesday, as remnant moisture upstream gets directed back towards the state. However, with no upper level support, showers will become lighter. Scattered windward showers expected for Kauai and Oahu Tuesday. The moisture will clear Maui County and Big Island by Wednesday morning, and expect to finally see drier trade wind weather through the end of the week.

Hawaii’s Marine Environment…as of 334am Monday:  Bands of scattered showers continue to impact waters surrounding Maui County and Big Island. A boundary northwest of the island chain will travel southeast across the state. Gentle variable to southerly breezes downstream of this boundary will transition to strengthened north-northeast winds behind the boundary passage. Moderate trades will become better established early this week, along with widely-scattered showers, as the upper trough passes east of the state Tuesday.

The northeast swell that peaked will continue to decline. A small north swell will reinforce an already established background north swell Tuesday and Wednesday. This will maintain elevated north-facing shore surf the next few days. Very small south-southwest swell will keep south-facing shore surf from going completely flat the remainder of the week. East surf will stay slightly elevated as result of a fading northeast swell and a little north wrap. East-facing shore short period wind waves will pick up response to strengthened trades Tuesday into Wednesday.

Interesting:  Seals Risk Death by Polar Bear for a Varied Meal, UBC Study Finds

As climate change reshapes Arctic food webs, ringed seals will swim into risky polar bear territory if the menu is varied enough.

That’s the central finding of a new study published in Ecology Letters. UBC researchers tracked 26 ringed seals and 39 polar bears in eastern Hudson Bay, using GPS and dive information to analyze how the animals found, and avoided becoming, food.

“Climate change is reshaping the Arctic, an area often seen as a foreshadowing of climate changes around the world,” said lead author Dr. Katie Florko, who conducted the research as a doctoral student at UBC’s Institute for the Oceans and Fisheries (IOF). “It’s not just melting sea ice: climate change is affecting everything: the predators, the prey and their habitats, effectively reshuffling a complex, intertwined system. If we map critical habitat while ignoring how bears and seals interact, we risk potentially protecting areas that animals are actually avoiding in a climate-changed future.”
