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. Here’s the webcam for the (~10,023 feet high) Haleakala Crater 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 Tuesday comments:  I’m with my friend Bob here at our vacation rental at Sea Ranch, Sonoma County, CA on a working vacation.

455am HST, it’s clear here at Sea Ranch, the low temperature was 46 degrees…with calm winds

528am HST, last night a racoon opened one of the screen doors in Bob’s room, and came in and ate our two remaining perfectly ripe avocado’s, and ransacked through a full bag of trash we were going to empty today! We could see his paw prints on the floor, and it wasn’t a small animal, it looked more like a grizzly bear paw prints…well, maybe not that big. However, it’s intimidating to have a wild animal invade your private dwelling space!

 

Hawaii’s Weather Highlights…as of Tuesday morning: Moderate to locally breezy trade winds today will be on the increase tonight, with locally strong winds Wednesday through Thursday, as a new high builds north of the state. Clouds and showers will be focused over windward and mauka areas, with some spilling over to leeward areas. Additional windward showers are expected late in the week, as a band of moisture moves from north to south across the state. Moderate to locally breezy trades will return over the weekend.

Weather Narrative…as of Tuesday morning: There is increased confidence in an increase in winds starting tonight, with advisory level winds possible. Several models suggest some areas like the Kohala mountains on the Big Island could see warning level winds tomorrow. The NBM is the model showing the highest winds, but other models also suggest high end advisory or low end warning levels.

A high pressure system far to the northwest of the islands is moving to the east. Although the GFS and ECMWF models don’t strengthen the high, the pressure gradient still tightens as a result of the high moving north of the islands. Winds will be strongest through gaps, and over and downslope of ridges, and the models show the winds strongest over Maui and the Big Island. The global models are showing the strongest winds on the Big Island summits tonight and tomorrow.

A cold front to the north through northwest of the islands will be partly responsible for an increase in shower activity later in the week. The boundary will move to the east, and weaken, and the moisture associated with the boundary will then get caught up in the trade wind flow. Tropical Storm Pena is nearly 800 miles southwest of the islands, and continues to move the west, away from the state.

Fire Weather: Fire weather conditions will remain near critical levels over the next several days, mainly do the uptick in winds tonight, that will persist through Thursday. Relative humidity values will decrease to near threshold values Tuesday and Wednesday, and winds are forecast to be close to threshold Wednesday/Thursday. Temperature inversion heights should remain between 6,000 and 8,000 feet from Maui County to the Big Island.

Marine Conditions…as of Tuesday morning: High pressure will build north of Hawaii through Wednesday. Fresh to locally strong trade winds will become strong across all Hawaiian waters tonight. As a result, the Small Craft Advisory expands in area to cover all coastal waters after 6pm and has been extended through Wednesday night. High seas are also forecast to exceed the threshold beginning Wednesday, with the arrival of a large north-northwest swell.

Meanwhile, a front drops south into the northern offshore waters tonight and weakens to a trough. The trough reaches the central waters by Wednesday night and leads to increased shower activity into Thursday. High pressure will gradually weaken heading into the weekend, and trades will gradually diminish back to fresh to locally strong levels.

A moderate, medium-period rise to the northwest swell will fade tonight. Moderate surf this morning will subside to small levels along north and west facing shores into tonight. A much larger northwest to north-northwest swell generated by the dynamic fetch of a gale force low near Kamchatka, will arrive on Wednesday, and may bring warning level surf heights to exposed north and west facing shores as it builds through the day and peaks Wednesday night. Surf will decrease to advisory levels on Thursday as the swell begins to fade and then fall below advisory levels by Friday. A northwest reinforcement is expected to arrive this weekend which could push surf back to advisory levels.

Surf along east facing shores will increase Wednesday as trade winds strengthen tonight. East shore surf remains elevated and choppy through Friday, then may diminish slightly this weekend.

A small, long-period south swell may bring a small rise to south shore surf on Wednesday.

“Mega Heatwaves” Strengthened by Interaction Between Soil Moisture, Atmospheric Pressure and Temperature

A new study has found a self-reinforcing interaction between temperature, soil moisture, and atmospheric pressure is being triggered at high temperatures, making extreme heatwaves 10 percent hotter than they would otherwise be. The study was published today in Science Advances and led by the Potsdam Institute for Climate Impact Research (PIK) and the International Institute for Applied Systems Analysis (IIASA).

Local temperature records have been shattered in heatwave hotspots where “mega heatwaves” have been increasing in frequency faster than more moderate extreme heat events in recent years. Notable examples include the 2022 heatwave in Europe, where temperatures in the UK topped 40°C for the first time, and the 2021 summer heatwave in the US Pacific Northwest, where recorded temperatures reached 4.6°C above previous records.

The new study identifies an emerging physical process underlying the most extreme heatwaves by using machine learning methods and statistical analysis. It found that most extreme heat events in the mid-latitudes (for example, Europe, southern Russia and Mongolia, eastern and north-western North America, north-western India, the western coast of South America, central and southern Africa, and northern interior Australia), are being topped up by soil moisture, atmospheric pressure and temperature interacting to drive higher temperatures.
