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 917pm Monday: After a prolonged stretch of impactful kona weather and heavy rainfall across the state, a gradual return to a more typical northeast trade wind pattern is expected by mid-week. A lingering moisture axis over the eastern end of the state, combined with an upper trough, will support periods of locally heavy showers on Tuesday, mainly over the Big Island. Thereafter, a drier and more stable trade wind pattern is expected from late week through the weekend into early next week.

Weather Details for the islands…as of 917pm Monday:  Latest satellite imagery shows the band of thunderstorms that impacted portions of the state earlier today has shifted well east of the Big Island, with mostly dry northeast trade wind conditions now prevailing across the island chain. Dew points have dropped into the lower 60’s across the western end of the state, resulting in noticeably cooler and more comfortable conditions compared to recent days.

The past several days have been exceptionally wet across portions of the state, particularly from Oahu through the Big Island. Peak rainfall totals over the past 5 days have generally ranged from 15 to 25 inches in some areas, with a statewide peak of 25.73 inches observed at Kaala on Oahu, most of which fell Thursday night into Friday. This recent period of heavy rainfall has led to saturated soils and elevated stream flows, leaving areas very sensitive to additional rainfall.

Looking ahead through mid-week, a lingering axis of moisture over the eastern end of the state combined with cold temperatures aloft associated with a departing but still influential upper trough, will maintain the potential for locally heavy showers on Tuesday, especially across the Big Island. Given the saturated ground conditions, even modest additional rainfall could lead to renewed runoff and localized flooding concerns. As a result, a Flood Watch may need to be extended through Tuesday afternoon for the Big Island.

Elsewhere, more stable conditions are expected as trade winds strengthen and drier air filters into the region. By Wednesday and beyond, the state should transition into a more typical trade wind pattern featuring passing windward showers, and generally drier leeward conditions. This pattern is expected to persist through the remainder of the week into the weekend, consistent with broader guidance indicating decreasing moisture and a return to climatological conditions

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.”
