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 Friday comments:  I’m at home here in upper Kula, Maui, Hawaii

521am, it’s mostly clear here at my place although with voggy air still, the low temperature 56 degrees, relative humidity is 83%…with calm conditions

1152am, just back from downtown Kahului to get my Covid and Flu shots. It’s partly cloudy, with some sunny and cloudy areas too…along with the vog, which was thick enough to preclude my morning walk.

415pm, very cloudy upcountry, and I’m have shower, with very large drops. It still looks like muted sunshine down towards the beaches…with vog.


Hawaii’s Weather Highlights
…as of Friday afternoon:
Hurricane Nolo has strengthened once again, although well away from our islands. A drier air mass will overtake Hawaii tonight into the weekend.

Weather Narrative…as of Friday afternoon: Trailing moisture induced by Hurricane Nolo`s circulation, which has affected the state for most of this week, finally has moved away. A drier air mass has established through the area, while winds also have shifted from a southerly to a more easterly direction.

Although relatively dry conditions will prevail across the state this weekend, showers are expected to develop at times. Early next week, the trades will weaken in response to an approaching surface trough from the northeast, and then will weaken further heading into mid-week, as broad troughing develops northwest of the state.

In this lighter wind flow, land and sea breezes will become increasingly more prevalent, with downslope land breezes, with clearing expected overnight, and clouds and a few showers developing over leeward and interior areas with daytime heating each afternoon.

Marine Conditions…as of Friday afternoon: As Hurricane Nolo continues to strengthen and moves farther west away from the Hawaiian Islands, its influence on local weather will wane. Gentle to fresh east to northeast trade winds will fill back in on Saturday, along with drier air settling over the area. A Small Craft Advisory may be needed for the typically windy waters and channels by late this weekend for locally strong trades. By the middle of next week, troughing developing northwest of the islands may cause the trade winds to weaken and veer out of the southeast once again.

A moderate, medium-period west to southwest swell originating from Nolo that has been affecting Niihau and Kauai will quickly fade tonight. Meanwhile, a small background south swell continues for other islands, holding surf mostly steady along south facing shores through the weekend. A new small, long-period south swell, originating from a large fetch of gale force winds southeast of New Zealand earlier this week, is forecast to arrive beginning Sunday and peak Monday through Wednesday.

Surf along north-facing shores saw a small bump today as a small, short to medium period swell moved into the region. This will peak late today, then decline into the weekend. Another increase in small north shore surf is possible early next week as a small, medium- period northwest swell arrives this weekend and peaks on Monday. This will be followed by a slightly larger long-period northwest swell peaking on Wednesday. Surf along east facing shores will see a slight boost and become more choppy as easterly trades build back into the region this weekend.

Atlantic Ocean:
There are no active tropical cyclones

Remnants of Fay

Showers and thunderstorms associated with the remnants of former Tropical Storm Fay located several hundred miles southeast of Bermuda have become less organized since yesterday. No further development is expected while it moves north-northwestward at 5 to 10 mph to the east of Bermuda.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…low…near 0 percent

Caribbean Sea: There are no active tropical cyclones

Gulf of America: There are no active tropical cyclones

 

Northeast Pacific

Tropical cyclone 18E (Rachel) is located about 260 miles south-southwest of the southern tip of Baja CA

RACHEL CONTINUES LASHING SOCORRO ISLAND AS IT MOVES SLOWLY WESTWARD

According to the NHC advisory number 23 

Rachel is moving toward the west near 5 mph (7 km/h), and this general motion is expected to continue through the weekend. A gradual turn toward the west-northwest with an increase in forward speed is expected by Monday. Maximum sustained winds are near 105 mph (165 km/h) with higher gusts. Some weakening is expected over the next day or two. However, Rachel is expected to remain a hurricane for the next several days. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). A few hours ago, the weather station on Socorro Island measured sustained winds of 61 mph (97 km/h) with a gust to 85 mph (137 km/h). The estimated minimum central pressure is 963 mb (28.44 inches).

>>> South of Southern Mexico:

An area of low pressure is forecast to form late this weekend or early next week south of the southern coast of Mexico. Thereafter, environmental conditions appear favorable for gradual development, and a tropical depression is likely to form by the middle of next week while the system moves slowly west-northwestward to northwestward.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…high…80 percent

 

Central North Pacific:

Tropical Cyclone 15E (Nolo) is located about 180 miles southeast of Maro Reef

NOLO STRENGTHENING AS IT CONTINUES WESTWARD …RAPID INTENSIFICATION POSSIBLE OVER THE NEXT DAY OR SO

According to the NHC advisory number 50

Nolo is moving toward the west near 7 mph (11 km/h). A mainly westward motion with an increase in forward speed is expected during the next few days. On the forecast track, the center of Nolo will continue to move through the Papahanaumokuakea Marine National Monument but remain just south of the Northwestern Hawaiian Islands west of French Frigate Shoals. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Rapid intensification is possible over the next day or so, and Nolo is forecast to become a major hurricane over the weekend. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 115 miles (185 km). The estimated minimum central pressure is 978 mb (28.88 inches).

Green Roofs and Living Walls Advance Urban Sustainability in Hawaii

A living laboratory at the University of Hawai?i at M?noa’s Magoon Research and Education Station is exploring ways to cool buildings and homes without expensive electricity bills while increasing local food production.

Led by Andy Kaufman, associate professor in the Department of Tropical Plant and Soil Sciences at the College of Tropical Agriculture and Human Resilience (CTAHR), the project evaluates vegetated roof and living wall systems designed for tropical island environments.

“There’s nothing like this that we know of in the world that’s this high-tech and this real-world application,” Kaufman said.
