Hawaii’s MountainsHere’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 (out of operation). 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 Saturday comments:  I’m at home here in upper Kula, Maui, Hawaii

512am, it’s mostly clear here in upper Kula with calm winds, and a low temperature at my place of 52.5 degrees…with the relative humidity 79%

907am, still sunny here in upper Kula, although there are lots of showery looking clouds towards the windward side of east Maui.

 

>>> Interesting weather web blog: Mauka Showers…Hurricane Fausto Heading Towards the Hawaiian Islands

 

We have Hurricane Fausto continuing to churn the waters of the eastern Pacific, to the east of the Hawaiian Islands. It will continue more or less westward over the next several days. It will cross over into our central Pacific today. From there it may eventually get close to Hawaii, or move by not far to the north. If this were to occur, we could see the associated cloud field bring heavy showers and gusty winds our way around Tuesday/Wednesday of next week. Additionally, we should see rising surf this weekend along the east facing shores…generated by Fausto. As we know, things may change going forward, so that I’ll keep abreast of these changes and make updates here as warranted.

Hawaii’s Weather Highlights…as of Saturday afternoon: A strong high pressure system far north of the Hawaiian Islands will continue to produce moderate to breezy trade winds through Monday, with periods of showers favoring windward mountain areas in the overnight to early morning hours.

Hurricane Fausto remains on track to pass near the Hawaiian Islands early next week. The latest forecast for Fausto shows a weakening trend to tropical storm strength, as it moves closer to the island chain. A drier and breezy trade wind weather pattern will return across the state Thursday onward, as Fausto drifts westward away from the Hawaiian Islands.

Weather Commentary…as of Saturday afternoon: A strong high pressure ridge remains locked in place north of the Hawaiian Islands, keeping easterly trade winds in the forecast through the end of next week. One exception to this trade wind weather pattern will develop early in the week, as Hurricane Fausto continues to track into the Hawaii region. Fausto remains on a high confidence east to west track towards the Hawaiian Islands, based on the latest forecast from the National Hurricane Center.

Hurricane Fausto will likely weaken to tropical storm strength, as the low center makes its closest point of approach near the Big Island on Tuesday, and near Kauai by Wednesday. However, subtle shifts in the storms track or intensity may lead to significant forecast changes in island by island weather impacts. It is strongly encouraged for the public to pay close attention to this passing storm system, as weather impacts over the Hawaiian Islands will likely evolve over time.

Potential Fausto Impacts Include…High surf above advisory thresholds along east facing shores from late Sunday through Tuesday, strong winds to around 40 mph with stronger gusts may develop near and north of the low center, and heavy rain threats are possible as Fausto moves from east to west across the region Tuesday through Wednesday.

No time like the present to review your family hurricane preparedness plans, and ensure every household has at least a 14 day supply of food and water available, if needed during this years active hurricane season.

A drier and more stable breezy trade wind pattern will fill in across the state Thursday onward, as Fausto continues to journey westward away from the Hawaiian Islands.

Marine Conditions…as of Saturday afternoon: Fresh to locally strong trade winds will persist through Sunday as robust high pressure centered far north of Kauai drifts westward, and the Small Craft Advisory (SCA) for the typically windy waters around Big Island and Maui County has been extended through Sunday afternoon. Trades should decline slightly and shift out of the north northeast late Sunday into Monday as Fausto approaches the area. The National Hurricane Center continues to call for Fausto to weaken to a tropical storm well before it passes near or just north of the islands Tuesday through Wednesday, but uncertainty in the eventual track of the tropical cyclone means that the wind forecast remains unclear.

The current south-southwest swell is on a gradual decline, but an overlapping pulse of south-southwest swell is expected today. Swell energy has been slowly lowering on the nearshore and offshore buoys overnight, though there has been building 17 second energy at the offshore NOAA buoy 51002 during the last couple of hours. As a result, south shore surf may briefly drop below the High Surf Advisory (HSA) threshold early this morning followed by a rise around midday. The HSA for south shores has been extended through tonight and may need to be pushed into Sunday if the swell remains elevated. The swell will then slowly decline Monday and Tuesday, with a smaller south-southwest swell possible during the middle of the week.

Rough east shore surf will remain a notch above seasonal average through tonight as a result of fresh to strong trade winds. The trade wind swell will drop slightly as long period swell from Hurricane Fausto begins to arrive tonight and Sunday. The Fausto swell will likely produce advisory-level surf along east facing shores Sunday night or Monday, and High Surf Warning conditions are possible during the peak on Tuesday or Wednesday, depending on the eventual track of the tropical cyclone.

Surf along north-facing shores will remain at flat to tiny levels through the weekend. Some increase is expected as Fausto or its remnants pass over the region Tuesday and Wednesday.

Central Pacific: There are no active tropical cyclone

>>> Well Southwest of Hawaii:

A large area of disorganized showers and thunderstorms located well southwest of the Hawaiian Islands is associated with a broad area of low pressure. Environmental conditions appear conducive for gradual development of this system while it moves generally westward at about 10 mph toward the International Date Line, and a tropical depression is likely to form in the western Pacific basin early next week.

* Formation chance through 48 hours…medium…40 percent
* Formation chance through 7 days…high…70 percent

Controlled Burns Have Saved Thousands of Giant Sequoias

The use of small, controlled burns to clear out flammable underbrush has saved thousands of giant sequoias from devastating wildfires, new research finds.The largest trees on Earth, sequoias can reach more than 300 feet tall and live for 3,000 years, but they grow only in a narrow band of the Sierra Nevada mountains in California, where hotter, drier weather has left forests increasingly prone to wildfires. With their thick bark and high canopies, the trees can withstand small fires, but the more intense blazes seen in a warmer climate have proved deadly for thousands of trees.Together, the 2020 Castle Fire and 2021 KNP Complex Fire killed as many as 13,000 giant sequoias, or close to a fifth of all sequoias. According to the new study, the death count would have been considerably higher without the use of prescribed burns.Read More: Yale Environment 360A controlled burn in Sequoia National Park.
