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.

Glenn’s Aloha Friday comments:  I’m at my friend Linda’s here in Corte Madera, Marin County, CA on a working vacation.

445am HST, it’s clear in Corte Madera, CA, the low temperature was 39.5 degrees here at Linda’s…with calm winds

1205pm, excellent pickleball games at Eastwood Park in Mill Valley this morning! The weather is perfect with a temperature of 68 degrees here in Corte Madera at the time of this writing.

335pm, a wonderfully warm and sunny day here in Marin County. The sun recently set, as Bob, Linda, and I just returned from a nice walk about…looking mostly at birds and trees.

Hawaii’s Weather Highlights…as of Friday evening: A plume of moisture associated with now Tropical Storm Pena well south of the islands, brought heavy rainfall to windward areas of the Big Island. While the deepest moisture has shifted off to the west, expect enhanced clouds and showers to continue into Saturday morning favoring Maui and Hawaii Counties.

A second tropical disturbance will pass to the south of the state early next week, possibly enhancing shower activity to southern portions of the Big Island. The next best chance for state-wide shower chances arrives late next week.

Weather Narrative…as of Friday evening: Tropical Storm Pena formed late this morning 650 miles southeast of South Point, HI. Mid level ridging north of the state will steer this cyclone west for the next several days, staying well south of Hawaii. A plume of rich moisture tied to Pena, which brought heavy rainfall to the Big Island over the last 24 hours, has largely shifted to the west, but trades and moist low levels will keep shower chances going for windward areas of Hawaii and Maui into Saturday. Additional showers are possible around Kona where sea breeze convergence has occurred.

A second disturbance behind the tropical storm will send another plume of deeper moisture westward Sunday into Monday. Guidance generally keeps this disturbance south of the Big Island, but it is expected to pass sufficiently close to keep an eye on. Shower chances increase for southern portions of windward Big Island Sunday night and Monday morning, but rainfall amounts will fall well short of the 2 to 5 inches that fell in Big Island windward areas in the last 24-30 hours.

The ridge to the north will settle farther southeast as the week wears on. Drier low level flow and lower inversion heights will keep shower chances limited mostly to windward areas of the Big Island and windward and mauka areas of the smaller islands. A front will reach the northern islands Thursday and the southern islands next Friday. Some increase in shower potential is possible, but the strong ridging in place should limit chances for widespread rain.

Fire Weather: An easterly wave passing south of the islands will continue to bring elevated humidity levels into Saturday morning. Fire weather conditions will remain below critical thresholds into next week. Temperature inversion heights will drop from 9-10,000 feet today to 6-8,000 feet for much of next week.

Marine Conditions…as of Friday evening: Fresh to strong trade winds with periods of near gales in the channels will prevail through the weekend, as high pressure persists north of the state. A Small Craft Advisory (SCA) remains in place for all Hawaiian Waters, due to a combination of winds and elevated seas through Saturday night. The SCA will likely remain in place through at least Sunday night. as Tropical Storm Pena passes several hundred miles to the south, keeping the local pressure gradient tight. Winds are expected to ease slightly late Monday and Tuesday, as the ridge to our north erodes, and Pena moves away to the southwest. The SCA will likely be trimmed back to the typical windy waters around Big Island and Maui at that time. Trade winds are expected to strengthen again on Wednesday.

A north-northwest swell will continue a slow decline through Saturday, and surf along exposed north and west facing shores has fallen below High Surf Advisory thresholds. A reinforcing medium- period energy out of the north-northwest (325 to 340 degree) should arrive late Saturday into Sunday. Surf should reach advisory thresholds during the peak of the swell Sunday morning. Another large northwest to north-northwest swell is Wednesday or Thursday.

A small south-southwest swell should produce surf slightly above seasonal average through Saturday. A tiny pulse from the south- southeast may maintain south shore surf near seasonal average Sunday and Monday, followed by background level surf through the remainder of the week.

Rough surf along east-facing shores will hold around seasonal average through much of the next week. Select northeast exposures should see long- period energy from the declining north-northwest swell into tonight.

Atlantic Ocean:
There are no active tropical cyclones

Western and Central Atlantic:

Invest 94L

A non-tropical low pressure area located several hundred miles south of Bermuda is producing limited shower activity. The chances of this low acquiring subtropical characteristics are decreasing due to strong upper-level winds that are expected to persist over the system into the weekend. The low is forecast to move generally eastward over the western and central subtropical Atlantic during the next couple of days and become absorbed by a new non-tropical low pressure system to its east later this weekend. Regardless, gale-force winds are likely over parts of the central subtropical Atlantic through the weekend.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…low…10 percent 

 

Caribbean Sea: There are no active tropical cyclones:

Gulf of America: There are no active tropical cyclones

 

Northeast Pacific: There are no active tropical cyclones

>>> Eastern East Pacific:

A broad area of low pressure located offshore of Central America is producing disorganized showers and thunderstorms. A tropical depression could form over the weekend while the low drifts slowly offshore. Thereafter, upper-level winds should prevent any further development. This system could bring areas of heavy rain to portions of Central America through the weekend.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 7 days…low…30 percent

 

Central North Pacific:

Tropical Storm Pena is located 620 miles south-southeast of South Point, Hawaii

Interesting: 
Black Coffee, Hold the Plastic

The lining in traditional disposable coffee cups can release plastic particles and be difficult to recycle, but a new plant-based coating can eliminate these issues with your morning brew.

A team of researchers from the University of Waterloo created a durable new coating from cellulose acetate that is reinforced with cellulose nanocrystals. Both components come from plants. Because the coating and the cup are both cellulose-based, the material has the potential to simplify paper recycling by reducing the need to separate conventional plastic liners from paper.

The plastic in use now is derived from fossil fuels, and it can persist in the environment for centuries after disposal. During testing, the conventional, plastic-lined coffee cups showed surface degradation and particle release, suggesting microplastics could enter the container’s contents and flow into our bodies. The researchers’ cellulose-based coating remained largely intact during the same testing.
