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’s Weather Highlights…as of Friday morning: An easterly trough passing on an east to west track, just south of the Hawaiian Islands, will combine forces with a weak upper low to the west of the state. Expect enhanced clouds and showers into Saturday morning favoring Maui and Hawaii Counties. Easterly trade wind speeds will also increase slightly through the weekend.

A second tropical disturbance passes farther south of the state early next week. This system will likely boost trade wind speeds as it will track too far south for any rainfall impacts. The next best chance for increasing statewide shower trends may develop by next week Thursday.

Weather Narrative…as of Friday morning: Satellite imagery shows an easterly wave passing just south of the Hawaiian Islands. Deep tropical moisture riding up into the eastern islands will increase cloud cover and boost shower activity across the state, favoring Maui and Hawaii Counties through Saturday morning.

A weak upper level low shown on the satellite water vapor channel will produce divergence aloft and assist in higher statewide shower trends over the western islands. These passing showers will favor windward mountain areas, with some of these stronger showers drifting into the typically drier leeward areas.

Isolated thunderstorms remains in the forecast this afternoon across the windward and interior mountain slopes of the Big Island, due to the abundant moisture and instability associated with the passing easterly trough. Confidence in this thunderstorm activity is moderated by the significant amount of cloud cover limiting heating along the mountain slopes of Mauna Loa and Mauna Kea, reducing the convective trigger needed to initiate thunderstorm development. If the clouds over the Big Island can clear up enough during the middle of the day, allowing the higher elevation mountain slopes to heat up, then thunderstorm development is certainly possible.

A tropical disturbance roughly 700 miles southeast of South Point on the Big Island continues to develop. This system will continue to drift westward and pass far south of the Hawaiian Islands over the next several days. This disturbance will likely develop into a tropical depression later today or on Saturday according to the latest National Hurricane Center discussion.

We’ll need to continue to closely monitor this developing system as it passes south of the island chain. More stable conditions are expected from Saturday afternoon through much of next week, in a drier moderate to breezy trade wind weather pattern. Stronger subsidence aloft under a strong ridge to the north of the islands keeps fair weather conditions in the forecast, limiting clouds and showers from late Saturday through next Wednesday.

Another round of wet trade wind weather may develop by next week Thursday and Friday as a cloud band, associated with an old dissipated cold front, moves into the islands from the north. Unstable clouds along this band will be lifted over island mountains on breezy easterly trade winds, and likely increase shower trends through Friday. Look for increased clouds and showers for this extended forecast time period. Confidence on these wetter trends for the end of next week remains fair at this time.

Fire Weather: An easterly trough passing south of the islands will increase clouds, trade wind speeds and humidity levels into Saturday morning. Fire weather conditions will remain below critical thresholds into next week. Temperature inversion heights near Maui and the Big Island today will remain near the 10,000 foot elevation level.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Looping Surface Precipitation…through the next 8-days / Vog Map

 

Marine Conditions…as of Friday morning: Fresh to strong trade winds with periods of near gales will prevail through the weekend as high pressure persists north of the state. A Small Craft Advisory (SCA) is in effect through at least Sunday night for all Hawaiian Waters, for a combination of winds and elevated seas as well as a tropical disturbance passing a couple hundred miles to the south. Winds are expected to ease slightly as the ridge to our north erodes, and the potential tropical cyclone moves away to the southwest. The SCA will likely be trimmed back to the typical windy waters around Big Island and Maui sometime Monday or Tuesday.

A long-period north-northwest swell is peaking and will decline below advisory thresholds late tonight or early Saturday morning. A reinforcing medium period energy out of the north-northwest (330 to 340 degree) should arrive late Saturday into Sunday. Surf could approach advisory thresholds during its peak early Sunday morning. Another large northwest to north-northwest swell is Wednesday or Thursday of next week.

A small south-southwest swell should peak today with waves slightly above average for this time of year along south facing shores.

Surf along east-facing shores will stay elevated and choppy through much of the week, due to the strong trades. Select northeast exposures should see long- period energy from the large north-northwest swell today through 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: There are no active tropical cyclones

>>>Well Southeast of the Hawaiian Islands:

Invest 95C

Showers and thunderstorms associated with a trough of low pressure located several hundred miles to the southeast of the Big Island of Hawaii continue to become better organized. However, recent satellite wind data indicate the system still lacks a well-defined center. Environmental conditions are conducive for additional development, and a tropical depression is expected to develop either later today or on Saturday. The system is forecast to move west-northwestward to westward at 10 to 15 mph, passing well south of the Hawaiian Islands.

* Formation chance through 48 hours…high…90 percent
* Formation chance through 7 days…high…90 percent 

 

Northwest Pacific Ocean:

Tropical Cyclone 31W…is located approximately 18 NM north of Pagan

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.
