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

5am, it’s mostly clear here in upper Kula with calm winds, and a low temperature at my place of 56.5  degrees…with the relative humidity 82%

 

>>> Highest Temperature Thursday, July 16, 2026 – 121 at Stovepipe Wells, CA
>>> Lowest Temperature Friday, July 17, 2026 – 36 degrees at Truckee, CA

 

Hawaii’s Weather Highlights…as of Friday morning: Locally breezy trade winds will remain active through the weekend, easing a bit early next week. Typical trade wind showers will favor windward and mountain areas.

Weather Commentary…as of Friday morning: High pressure remains anchored far northeast of the islands. The pressure gradient over the islands, supports the light to moderate trade wind flow we have been experiencing recently. The high is expected to weaken and lift to the north, and the weaken.

The resultant pressure gradient over the islands should weaken, leading to winds easing a bit more to start next week. As a new high builds north of the islands by mid-week, with the pressure gradient over the islands tightening, leading to an increase in the trades.

High pressure aloft will maintain a stable atmosphere, limiting clouds and showers, mostly to the windward and mountain areas.

Marine Conditions…as of Friday morning: As high pressure far north of the islands edges slightly south and east through this weekend, and interacts with a couple of lows and troughs passing to the south and southwest of Hawaii, trades will remain fresh to strong. A Small Craft Advisory (SCA) is in effect for the windier channels and waters around Maui County and the Big Island through Saturday afternoon. Winds will begin to diminish again late this weekend as high pressure to the north starts to weaken, which should eliminate the need for a SCA Sunday into early next week.

A small, medium-period west-northwest swell will gradually fade into the weekend, causing surf along north-facing shores to drop to flat to tiny by the weekend.

Meanwhile, south-facing shores remain slightly below average, as old southwest and west-northwest swells fade. However, a fresh south-southwest swell building today, will briefly boost surf back to near average through early Saturday. This will maintain small surf along west-facing shores as well. A larger, moderate south swell is expected to build Sunday through early next week, bringing potentially above-average (though sub-advisory) waves to south shores.

On east-facing shores, strengthening trade winds will make surf slightly bigger and choppy this weekend, with a potential small-to- moderate swell arriving early-to-mid next week from Tropical Storm Elida.

World-wide Tropical Cyclone Activity


>>> Here’s a link to the latest Pacific Disaster Center’s Weather Wall


>>> Atlantic Ocean: There are no active tropical cyclones


Eastern Tropical Atlantic:

A broad area of low pressure, associated with a tropical wave is located about 175 miles southeast of the Cabo Verde Islands. The low continues to produce a limited and disorganized area of showers and thunderstorms while it moves west-northwestward at 10 to 15 mph. Significant development of this system is not expected before environmental conditions become even less favorable for development over the weekend.

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

 

Northeastern Gulf of America and Offshore of the Southeastern U.S.:

An area of low pressure is forecast to form this weekend over the northeastern Gulf of America. Some gradual development of this system is possible while it meanders over the northeastern Gulf, northern Florida, or the extreme western Atlantic near northeastern Florida early next week.

* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 7 days…low…20 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 05E (Elida)…is located about 825 miles west-southwest of the southern tip of Baja California

ELIDA STILL HAS NOT SHOWN MUCH CHANGE IN INTENSITY

According to the NHC Advisory number 12

Elida is moving toward the west-northwest near 10 mph. A turn toward the northwest is expected later today, followed by a north-northwestward motion at a slightly faster forward speed by Sunday. Maximum sustained winds are near 65 mph with higher gusts. Some strengthening is possible, and Elida could still become a hurricane within the next day. Weakening is expected to start over the weekend and continue into early next week. Tropical-storm-force winds extend outward up to 160 miles from the center.

>>> Central and Western East Pacific:

A tropical wave located several hundred miles south-southwest of the coast of southwestern Mexico is producing a large area of disorganized showers and thunderstorms. Environmental conditions appear conducive for development of this system, and a tropical depression is expected to form over the weekend while it moves west-northwestward to northwestward at 10 to 15 mph over the central portion of the eastern Pacific.

* Formation chance through 48 hours…high…70 percent
* Formation chance through 7 days…high…90 percent

 

>>> Eastern and Central east Pacific:

A broad area of low pressure is forecast to develop well to the south of Mexico during the middle to the end of next week. Environmental conditions could support some gradual development of this system thereafter while it moves westward to west-northwestward across eastern and central portions of the eastern Pacific.

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

>>> Well Southwest of the Hawaiian Islands:

Invest 90C

A broad area of low pressure located a few hundred miles southeast of Johnston Atoll is producing disorganized showers and thunderstorms away from the center. Development of this system, if any, is expected to be slow to occur while it moves westward at about 10 mph during the next day or so. Environmental conditions are expected to become unfavorable for further development by this weekend.

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

 

>>> Northwest Pacific Ocean:  There are no active tropical cyclones

>>> Southwest Pacific Ocean: There are no active tropical cyclones

>>> North and South Indian Oceans / Arabian Sea: There are no active tropical cyclones

Interesting:  What is No?Till Farming, and is it Actually Better for the Environment?

Humans have been turning seeds and soil into food for thousands of years.

We first started cultivating edible plants at the end of the last Ice Age, roughly 12,000 years ago. Ploughing made this possible.

Ploughing, also known as tilling, is the process of turning over soil to bury weeds, loosen the earth and bring fresh nutrients to the surface.

But ploughing, particularly over long periods, can erode the soil and make it less healthy. This is where conservation-focused farming methods, including no-till farming, come in.
