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.

 

>>> Highest Temperature Sunday, March 22, 2026 – 106 degrees at Death Valley, CA
>>> Lowest Temperature Monday, March 23, 2026 – 12 degrees at Mount Washington, NH

 

– Flood watch for the Big Island
– Rain and thunderstorm potential focused on Maui and the Big Island, with flash flooding possible for Big Island late morning into the afternoon.
– Decreasing flood and thunderstorm threat tonight.

 

Hawaii’s Broad Brush Weather Overview…as of 922am Monday:  The kona low continues to move rapidly towards the northeast away from the state, and a high pressure system builds in quickly as the low departs. An upper level subtropical jet stream and deep unstable band of tropical moisture lingers over the Big Island today.

This larger scale moisture band will drift eastward as high pressure builds in from the northwest, allowing more stabilizing trade winds to spread down the island chain. These cooler moderate to locally breezy trade winds will lower humidity levels and continue blowing across the islands through the upcoming weekend, with passing showers favoring windward and mountain areas.

Short Term Update…as of 922am Monday:  Increased chances for rain and rainfall amounts across Maui based on current radar and satellite trends. Scattered showers and thunderstorms persist across windward Maui and waters around both Maui and Big Island. Expecting this activity to impact Big Island today as daytime heating and sea breezes enhance this activity over land. Maui can also expect ongoing windward showers through the day.

Weather Details for the islands…as of 334am Monday: Trade winds are returning faster than predicted, with northeasterly winds observed this morning as far east as the islands of Molokai and Lanai. This mornings water vapor satellite imagery channel shows a Subtropical Jet stream over Maui County and the Big Island. Enough instability lingers near Lanai for thunderstorms to develop along a trade wind convergence band just southwest of the island. These thunderstorms are not moving and are likely anchored along this down stream convergent feature, which makes it less likely to build over the islands in Maui County.

A strong upper level divergent wind signature continues to produce scattered thunderstorms along the southwestern edge of the jet streams southern edge. These thunderstorms are developing on the tail of the deep tropical moisture plume, which may move into the Big Island later today. Heavy rain under this thunderstorm `tail` tracking towards the Big Island, is the primary reason to extend the Flood Watch through the afternoon hours for Hawaii County. This watch will likely be cancelled for the Big Island once this last thunderstorm threat clears Hawaiian airspace.

The weather pattern changes back to northeasterly trade winds today, and the threat for heavy rain diminishes. A passing upper level trough drifting southeastward down the island chain will keep periods of moderate showers in the forecast for all windward mountain slopes. Downward trends in shower activity will develop over each island as the trough axis passes, and downward vertical motions (subsidence) strengthens as the upper ridge begins to build in aloft. The trough will pass through Kauai and Oahu through the overnight hours, then pass through Maui and Hawaii Counties by Tuesday. Cooler temperatures are expected to last into the weekend, as moderate to locally breezy trade winds bring cooler air with lower humidity levels into the Hawaiian Islands from the north.

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.”
