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 Sunday comments:  I’m here at home through the winter in upper Kula, Maui

It’s clear to partly cloudy here in Maui County early this morning…with a low temperature of 51.5 degrees at my place, with the relative humidity 77 percent.

Early this afternoon the clouds have thickened and there are localized showers popping up here and there on Maui…including here at my place.

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

 

Hawaii’s Broad Brush Weather Overview: Light trades give way to southerly winds by mid-week. A cold front will bring a brief round of showers to Kauai through Oahu, before stalling just west or possibly over Maui County. The front then dissipates as it lifts north late in the week. Winds generally hold out of the south through next weekend.

Hawaii’s Weather Details: Blocking high pressure anchored over the western Aleutians favors a southward-displaced Pacific jet stream. This in turn favors a tendency for low pressure to develop near/west of the islands with more frequent opportunities for rainfall. In the near term, light to moderate trades will usher existing moisture west of the islands tonight, bringing an end to organized shower activity that has focused over windward and mountain areas, particularly on Maui and the Big Island.

Deepening mid-level troughing to our west elicits upstream pressure falls, that wipe out the local pressure gradient causing light SE/south winds, to be variable at times through mid-week. Afternoon sea breezes may have just enough moisture to produce pockets of light showers over island interiors, but generally speaking, moisture remains limited and dry mid-level air will provide a firm capping inversion throughout this time.

This trough triggers a frontal wave north of the islands, that helps sweep a shallow cold front into the area, that will reach Kauai on Wednesday night and Oahu on Thursday, before stalling near or over Maui County. Light southerlies may deliver pockets of leeward showers upon the approach of the front, but the bulk of rainfall will focus windward and mountains, especially over Kauai.

Strong consensus exists among the suite of global models that the Pacific jet stream will continue to sink southward during the forecast period, bringing potential for another frontal passage over the western portion of the state early in the following week.

Fire weather: Conditions remain below critical fire thresholds through the week, as winds remain light and RH elevated. Winds further ease as the week progresses, eventually transitioning to southerly.

Hawaii’s Marine Environment: A surface high pressure ridge will remain north of the Hawaii region, winds flowing around this ridge will produce gentle to moderate easterly winds, then decreasing and veering more southeasterly to southerly from Tuesday to Wednesday, as another cold front moves into the area from the northwest. A consensus of weather model guidance suggests this cold front may move into the western Hawaiian islands from late Wednesday into Thursday, then diminishing by Friday.

The current medium period north-northwest (340-350 degree) swell continues to slowly fade into Monday, bringing surf back down to below average levels for this time of year. The next two long to medium period overlapping northwest (310-320 degree) swell pulses will arrive on Monday and Tuesday, boosting surf along north and west facing shores, and possibly reaching marginal advisory levels by Wednesday.

Choppy east shore surf will remain small and decline for the next few days as trades gradually ease. Expect minimal background energy for south facing shores keeping south shore surf heights above flat levels.

Peak monthly tides combined with water levels that are running higher than predicted, will likely lead to minor flooding along the shoreline and in low-lying coastal areas. Coastal flooding is possible through the peak high tide.

Interesting:  New Study Finds That Drones Can be a Valuable Ally in Elephant Conservation

Once seen as a source of alarm, drones (or Unmanned Aerial Vehicles, UAVs) are now proving to be surprisingly elephant-friendly and a valuable research tool. Previously, the use of drones in elephant conservation has mostly relied on their power to disturb: with their buzzing propellers, which can sound like a swarm of bees, elephants reliably run from drones, making them a useful tool to drive elephants from croplands.

But new research published by Oxford University and Save the Elephants (STE) has concluded that elephants can learn to ignore drones, particularly when they are flown in a way designed to minimize disturbance. Flying a drone high (120 metres or above), with a downwind approach and steadily caused minimal stress to the elephants, with only temporary changes seen in their behavior, if at all.
