Hawaii’s MountainsHere’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 Wednesday comments:  I’m here at home through the winter in upper Kula, Maui

It’s clear here in Maui County early this morning, with high cirrus clouds which lit up a pretty pink at sunrise…with a chilly low temperature of 46 degrees at my place, with the relative humidity 77 percent.

Incredible Lava flow Fountain on the Big Island – December 6th

 

Hawaii’s Broad Brush Weather Overview: Southwest kona winds will cover most islands today, as winds veer in advance of an approaching cold front. This cold front will bring a band of moderate to heavy showers to Niihau/Kauai tonight, to Oahu Thursday morning, and to Maui County Thursday afternoon into the night. A more significant front will move into the state early Sunday and linger for several days. This front has an even higher potential for heavy rain.

Hawaii’s Weather Details: Satellite and radar show light showers spread across the islands, with partly to mostly cloudy skies. Winds will become southwesterly over most areas this afternoon, as they veer in advance of an approaching cold front. This initial cold front does not have strong support aloft, and will bring a band of moderate to perhaps heavy showers to mainly the western end of the state. Models have been consistent in showing the front reaching Niihau and Kauai later today, then Oahu Thursday morning, and likely reaching Maui County Thursday afternoon and evening. The front will weaken further as it retreats to the northwest Friday and Friday night.

Saturday will bring relatively light winds, resulting in a return to sea- and land-breezes. Showers will be around, but the chance for heavy rain will be sless compared to Thursday/Friday and Sunday-Tuesday.

A more significant front will move back in from the northwest Saturday night. Plenty of moisture will be drawn up from the south and over much of the state as this front approaches. Models have not converged on a solution concerning how far south and east the front will make it, but the additional moisture from the south, along with the stronger dynamics aloft, will result in a heightened chance of significant rainfall for several days over most if not all of the state.

If the latest models runs are supported by following runs, this risk may last well into next week. This looks like it will be our first strong wet-season system. Thunderstorms will most likely end up in the forecast for Sunday and Monday and perhaps into Tuesday.

Fire weather:  Conditions should remain below critical fire thresholds through the week with light winds and elevated RH. Temperature inversion heights should linger around 6,000 to 7,000 feet through Thursday.

Hawaii’s Marine Environment: Light southerly winds will hold today as a front approaches from the northwest. The front will enter the Kauai waters late tonight and move west to east across the state through Thursday before stalling and dissipating around Maui County Thursday night. An increase of showers are expected along and ahead of the front with moderate northerly winds following behind it. Another front approaching from the northwest will generate moderate southerly winds this weekend, with an increase of showers expected on Sunday.

A new moderate, long period northwest swell (320 degree) continues to fill in 1 to 2 feet above guidance. A reinforcing north-northwest swell (330 degree) is expected to fill in tonight and peak Thursday morning, keeping surf elevated. A Small Craft Advisory has been issued for seas building around Kauai and windward Oahu waters as the current swell peaks. A High Surf Advisory for select north and west facing shores remains in effect through Thursday. These overlapping swells will slowly decline Thursday night into the weekend. Another moderate, long period northwest swell (320 degree) should gradually fill in on Sunday, and could produce surf near the advisory threshold by Sunday evening.

Small, choppy east shore surf will become minimal over the next few days, as winds near and upstream become disrupted by approaching fronts. Expect minimal background surf for south facing shores, with a minor south-southwest pulse expected into Thursday.

Interesting: Nearly 8,000 Animal Species at Risk as Extreme Heat and Land-Use Change Collide

Almost 8,000 animal species could be pushed closer to extinction by the end of this century as the interacting effects of climate change-driven extreme heat and human land-use change create increasingly unsuitable conditions across their habitats, according to new research from a international research team led by Dr Reut Vardi of the School of Geography and the Environment, University of Oxford.

The study, ‘Effects of future climate extreme heat events and land use changes on land vertebrates’, published today in Global Change Biology, assessed nearly 30,000 species of amphibians, birds, mammals, and reptiles. It examined how future extreme heat events and projected land-use changes will affect species across their preferred habitats and thermal limits.

Dr Reut Vardi, Postdoctoral Researcher, School of Geography and the Environment, said:

‘Our research highlights the importance of considering the potential effects of multiple threats together to get a better estimation of their potential impact. It further stresses the urgency of conservation and mitigation actions globally to prevent immense losses to biodiversity.’
