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.

Hawaii Weather Narrative

Glenn’s Tuesday comments:  I’m at home here in upper Kula, Maui, Hawaii

452am, it’s cloudy here at my place here in Kula with a low temperature of 62.5 degrees, and the relative humidity is 87%

 

Hawaii’s Weather Highlights…as of Tuesday morning: Moderate to locally breezy trades continue, as showers focus primarily over the windward and mountain areas.

Weather Narrative..as of Tuesday morning: Guidance shows that some deeper moisture will remain across the islands today in the wake of now retired TC Moke, potentially fueling some local downpours.

The models agree to then show a trend for drier conditions in a windward terrain focusing shower pattern for the rest of the week, as strong high pressure holding to the north of the state, continues to support moderate to gusty island winds.

There is a signal to monitor for some tropical moisture feed toward the state into early-mid next week.

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 MapLooping Surface Precipitation…through the next 8-days / Vog Map

 

Marine Conditions…as of Tuesday morning: Fresh to locally strong trades will persist as now retired Tropical Depression Moke passes far southwest of the island chain, and broad high pressure remains north of the state. Convection associated with this system will remain over the far southern portion of the offshore waters as it tracks west.

Maui Leeward Waters has been removed from the Small Craft Advisory, and now only includes the typical windy waters around Maui County and the Big Island.

Surf along east facing shores will remain rough and choppy, due to persistent trade wind swell. Surf along south facing shores will remain below summer average, as a small, medium period south swell slowly fades today. An overlapping small, long period south southwest swell will fill in Tuesday, that should keep surf below the summer average. A slightly larger long period south swell will fill in Wednesday, and peak Thursday into Friday. This swell could push surf towards advisory thresholds before slowly fading over the weekend. Surf along north facing shores will remain tiny.

Weather Wall



Atlantic Ocean: There are no active tropical cyclones

>>> Central Subtropical Atlantic:

Invest 95L

An area of low pressure located several hundred miles northeast of Bermuda is moving north-northeastward at 15 to 20 mph. The associated shower activity remains disorganized and the circulation is broad and elongated. This system could still become a short-lived tropical depression or storm tonight before encountering increasingly hostile conditions by early Wednesday, likely ending its chances for development.

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

 

>>> Eastern Tropical Atlantic:

Invest 96L

Showers and thunderstorms associated with an area of low pressure centered a few hundred miles south-southeast of the Cabo Verde Islands have changed little in organization over the past several hours. However, environmental conditions appear conducive for gradual development, and this system is likely to become a tropical depression during the next day or two while it moves westward to west-northwestward across the eastern and central tropical Atlantic. Environmental conditions could become less conducive for development by the weekend.

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

 

Caribbean Sea: There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7 days.

Gulf of America: There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7 days.

 

Northeast Pacific: 

Tropical Cyclone 09E (Iselle)…is located about 730 miles west of the southern tip of Baja California

LARGE ISELLE FORECAST TO SLOWLY WEAKEN DURING THE NEXT FEW DAYS

According to the NHC advisory number 9…

Iselle is moving toward the west-northwest near 10 mph, and this general motion is expected for the next couple of days, with a turn towards the west possible on Thursday. Maximum sustained winds remain near 70 mph with higher gusts. Slow weakening is forecast during the next few days. Tropical-storm-force winds extend outward up to 205 miles from the center. The estimated minimum central pressure is 988 mb (29.18 inches).

Tropical Cyclone 10E (Julio)…is located about 675 miles west-southwest of the southern tip of Baja California

JULIO A LITTLE STRONGER BUT SHOULD BECOME ABSORBED BY ISELLE LATER TODAY

According to the NHC advisory number 4…

Julio is moving toward the north-northeast near 22 mph. This general motion is expected to continue today. Maximum sustained winds are near 50 mph with higher gusts. Little change in strength is forecast before Julio becomes absorbed by Tropical Storm Iselle later today. Tropical-storm-force winds extend outward up to 175 miles from the center. The estimated minimum central pressure is 1001 mb (29.56 inches).

 

>>> Central East Pacific:

A tropical wave located well to the south of southern Mexico is producing a large area of disorganized showers and thunderstorms. Environmental conditions appear favorable for development of this system, and a tropical depression is expected to form in a few days while it moves generally west-northwestward at 10 to 15 mph, well offshore of Mexico.

* Formation chance through 48 hours…medium…40 percent
* Formation chance through 7 days…high…90 percent 

 

>>> Western East Pacific:

A trough of low pressure located well to the east-southeast of the Hawaiian Islands is producing some disorganized showers and thunderstorms. An area of low pressure is forecast to form along the trough during the next couple of days, and environmental conditions appear conducive for some gradual development thereafter. A tropical depression could form during the latter part of the week or early this weekend while the system drifts generally north-northeastward.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 7 days…high…70 percent

 

>>> Well Offshore of Southern Mexico:

An area of low pressure could form well offshore of Central America late this week or this weekend. Environmental conditions should support some gradual development of this system, and a tropical depression could form late this weekend or early next week while it moves westward to west-northwestward at 10 to 15 mph well offshore of southern Mexico.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…50 percent 

 

Central North Pacific:

Tropical Cyclone 01C (Lala)…is located about 460 miles north of Kure Atoll

LALA SHOWING LITTLE CHANGE

According to the NHC advisory number 53…

Lala is moving toward the west-northwest near 6 mph, and a slow west-northwestward to northwestward motion is expected for the next few days. Maximum sustained winds are near 50 mph with higher gusts. Gradual weakening is expected during the next couple of days, and Lala is forecast to become a post-tropical cyclone on Thursday. Tropical-storm-force winds extend outward up to 125 miles from the center. The estimated minimum central pressure is 994 mb (29.36 inches).

 

Remnants of Tropical Cyclone 02C (Moke)…is located about 435 miles east of Johnston Island – Last Advisory

MOKE IS NO LONGER A TROPICAL CYCLONE

According to the NHC advisory number 20…

The remnants are moving toward the west near 14 mph, and this motion is expected to continue today. Maximum sustained winds are near 35 mph with higher gusts. The estimated minimum central pressure is 1006 mb (29.71 inches).

 

>>> Central Pacific:

An area of low pressure could form well south of the Hawaiian Islands late this week. Some gradual development is possible by the weekend into early next week while the system moves slowly to the west or west-northwest, well south-southwest of the Hawaiian Islands.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…low…20 percent

Natural Restoration Is Key to Reviving Threatened Tropical Rainforests

As nations race to restore ecosystems and curb climate change, research has shown that letting nature do the work is a cost-effective and viable solution.

A study from The University of Queensland and the University of Newcastle found natural forest regeneration delivered substantial carbon and biodiversity benefits and could be up to 96 per cent cheaper than traditional tree-planting programs.

School of the Environment PhD candidate Jiaqi Li said the team researched how the costs and benefits of natural regeneration varied across the tropics and created an interactive global map to explore the opportunities for forest regions.

“Nature is a great gardener, sometimes we just need to get out of its way while providing a bit of support,” Ms Li said.
