Hawaii’s MountainsHere’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) 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 Aloha Friday comments:  I’m here in Corte Madera, California, I hope you have a great Friday wherever you happen to be spending it.

I played Pickleball in Mill Valley this morning, which was lots of fun, and played 6-games, which is more than usual.

 

Hawaii’s Broad Brush Weather Overview:  High pressure far north-northeast of the islands will maintain a tight pressure gradient back toward the islands. This will produce gentle to breezy trade winds through tonight. Occasional periods of moisture moving in from the east will promote higher shower frequency and coverage.

Showers will ride in on the trade winds and primarily focus along windward and mountain exposures. The trades will slightly back off this weekend with less shower activity. The approach of a cold front may initiate a more wet pattern as we reach next week.

Hawaii’s Weather Details:  A surface high centered around 850 miles north-northeast of the state remains the main driver to breezy conditions today. Radar and satellite imagery show scattered to numerous light to moderate showers riding in with the trade winds and mainly focused along windward and mauka areas.

The Puna District of the Big Island and windward Maui are a couple of areas that have been experiencing the more persistent rainfall. The past 12 hour rainfall totals for this area range around 1-3 inches. Expect shower conditions to improve slightly as dryer air tries to filter in.

Starting tonight a front moving north of the state will weaken the high to our north, easing trade wind speeds through the weekend, to more gentle to locally breezy speeds. Expect bands of showers embedded in the trade wind flow to maintain scattered showers along windward areas, with some showers spilling over to leeward areas, especially overnight and during the early morning hours through the weekend.

The weather pattern will shift early next week, as a low level trough and tropical moisture moves from east to west across the state. This will bring an increase in showers starting with the Big Island Monday morning, then spreading to the rest of the state Tuesday ahead of the approaching front from the northwest.

Models are in general agreement that another strong front will move over the state by mid-week, bringing with it another potential for showers ahead of the front, and strong northerly winds following behind with a significantly drier airmass.

There are some differences between the GFS and EC models by mid-week regarding the timing and vertical features, which will impact the fine details, however overall both models show a wetter pattern starting next week, with a drier and cooler airmass filtering in during the second half of the week.

Hawaii’s Marine Environment:  Fresh to strong easterly trade winds will continue. Winds will then ease into the moderate to locally fresh range out of the east-southeast over the weekend and into early next week. An uptick in winds is expected towards the middle of next week, as a front moves across the waters. A Small Craft Advisory remains in effect for the typical windier waters around Maui and the Big Island.

A small north-northeast swell will decrease. Thereafter an upward trend is expected due to a storm force low centered over the western Bering Sea, that showed a large swath of storm-force winds aimed at Hawaii within the 310-330 degree directional bands. Expect small forerunners to arrive tonight from the north-northwest, then build through the weekend, with peak surf heights arriving by Sunday. Surf heights look to approach advisory levels for exposed north and west facing shores Sunday. The northwest swell heights will gradually decrease on Monday and then hold through Tuesday.

Surf along east facing shores will remain rough due to the strong trades locally and upstream across the eastern Pacific. A slight downward trend is expected this weekend.

Surf along south-facing shores will remain small, with mainly a mix of southeast and background south swell energy.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:  There are no active tropical cyclones

>>> Southwestern Caribbean Sea:

Surface observations and satellite imagery indicate that a broad area of low pressure is forming over the southwestern Caribbean. Additional gradual development is possible over the next several days, and a tropical depression is likely to form late this weekend or early next week while the system drifts generally northward or northwestward over the central or western Caribbean Sea. Regardless of development, locally heavy rains are possible over portions of the adjacent land areas of the western Caribbean including Jamaica, Hispaniola, and Cuba.

* Formation chance through 48 hours…medium…40 percent
* Formation chance through 7 days…high…80 percent

>>> Northeastern Caribbean Sea and Greater Antilles:

A trough of low pressure located near Puerto Rico is producing a large area of showers and thunderstorms over portions of the Greater Antilles and the adjacent waters of the Atlantic and the northeastern Caribbean. Slow development of this system is possible during the next couple of days as it moves west-northwestward near the Greater Antilles. After that time, this system is expected to be absorbed into the low pressure area over the Caribbean. Regardless of development, locally heavy rains are possible during the next several days from the northern Leeward Islands westward across Puerto Rico and Hispaniola to eastern Cuba and the southeastern Bahamas.

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

>>> North Atlantic:

Invest 96L

Showers and thunderstorms near the center of a low pressure system located a few hundred miles west-northwest of the Azores continue to show signs of organization. Environmental conditions appear favorable for some development during the next day or two, and the system could become a subtropical or tropical storm as it moves generally east-southeastward during the next few days. Interest in the Azores should monitor the progress of this system.

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

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific: 

Tropical Cyclone 13E…is located about 1500 miles west-southwest of the southern tip of Baja CA

DEPRESSION MOVING WESTWARD WITH LITTLE CHANGE IN STRENGTH

The depression is moving toward the west near 7 mph, and this general motion is expected to continue for the next several days. Maximum sustained winds are near 35 mph with higher gusts. Little change in strength is forecast during the next few days.

>>> Southwest of Southwestern Mexico:

An area of low pressure is developing well offshore of the southwestern coast of Mexico, currently associated with an area of disorganized showers and thunderstorms. Some slow development of this system is possible as it begins to drift slowly eastward or east-northeastward by the early to middle part of next week.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…low…30 percent

Interesting:  How to Grow a Forest: It Takes More Than Just Planting Trees

Trees and forests are often seen as symbolic of nature, and for good reason: They are vitally important to both the planet and to people. More than three-quarters of the world’s terrestrial biodiversity occurs in forests. Wooded areas filter and manage rainwater, provide shade, soak up pollution, regulate climate, provide oxygen, and salve our spirits.

In the face of threats from deforestation, ecosystem degradation, pests, and more, about 38 percent of the planet’s 166,000 tree species are now at risk of extinction, according to an October assessment from the IUCN. Increasing the planet’s tree coverage would have positive benefits for the climate and our ecosystems, scientists agree, but how we go about that is complicated.

In an interview with Yale Environment 360, Jake M. Robinson, a researcher in restoration genomics at Flinders University, in Adelaide, South Australia, talked about how reforestation efforts can go awry if done poorly, reducing biodiversity and harming local populations.
