Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (nearly 13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the 10,000+ 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.

Celebrating the end of summer…and the beginning of the autumn season

 

~~~ Hawaii Weather Narrative ~~~

 

Broad Brush Overview: Drier weather with strengthening trades is expected through Saturday, as a weak trough of low pressure north of Kauai continues away westward. Clouds and showers will favor the typical windward locations through Saturday night. Warm and muggy conditions are forecast to return later in the weekend through early next week…as low pressure forms west of the state. Light to moderate southerly winds and lots of tropical moisture from the deeper tropics will bring increasing off and on showers Sunday night through Wednesday.

Looking Ahead: A wet pattern returns later Sunday through the first half of the new week ahead, especially for the western end of the state. Light to moderate southerly breezes, along with deep tropical moisture moving northward over the state…will bring warm and very muggy conditions with increasing showers. If this all pans out as expected, the potential for heavy rainfall is possible. Forecast uncertainty remains high, although likely deep moisture will align across the western end of the state…with a few thunderstorms possible locally.

Marine Environmental Conditions: High pressure northeast of the state will keep a moderate to locally strong trade wind flow in place through Saturday. An area of low pressure is expected to develop several hundred miles northwest of Kauai over the weekend, and this should allow the winds to weaken and shift around to the southeast Sunday through early next week.

Surf will remain below advisory levels along all shores through the middle of next week. The current south swell will continue to slowly decline through Saturday. Rough surf will remain around the summer average along east facing shores through tonight, then decline during the weekend. The first large northwest swell of the season could arrive late next week…possibly reaching advisory levels along north and west facing shores.

>>> Atlantic Ocean: 

Tropical Cyclone 11L

NHC textual advisory
NHC graphical track map

According to the NHC advisory 2…The depression is moving slowly toward the west near 5 mph. A slow westward or west-northwestward motion is expected during the next couple of days. Maximum sustained winds are near 35 mph with higher gusts. Little change in strength is forecast during the next day or so, and the depression is expected to dissipate east of the Lesser Antilles by Sunday night.

1.) Shower and thunderstorm activity continues to become better organized near the center of a low pressure system located about 500 miles south of the southern Cabo Verde Islands, and a tropical depression appears to be forming. If these trends continue, advisories will be initiated on this system later today while the low moves westward at about 20 mph.

* Formation chance through 48 hours…high…80 percent
* Formation chance through 5 days…high…80 percent

2.) A broad area of low pressure located about 200 miles south of Bermuda is producing only minimal shower activity. Strong upper- level winds are expected to diminish by Sunday or Monday, which could allow for some slow development of this system while it moves westward and then northwestward over the southwestern Atlantic Ocean. By the middle of next week, upper-level winds are likely to strengthen again, which would limit additional development as the system moves closer to the southeastern coast of the United States.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 5 days…low…30 percent

3.) Satellite imagery indicates that a non-tropical low pressure system is forming along a frontal boundary about 900 miles west-southwest of the Azores. Conditions are expected to become conducive for the low to acquire subtropical or tropical characteristics, and a subtropical or tropical cyclone is likely to form by early next week while the low meanders over the central Atlantic Ocean.

* Formation chance through 48 hours…medium…60 percent
* Formation chance through 5 days…high…70 percent

>>> Caribbean Sea: No active tropical cyclones

>>> Gulf of Mexico: No active tropical cyclones

>>> Eastern Pacific: 

1.) An area of low pressure is expected to form in a couple of days well south of the southern coast of Mexico. Environmental conditions are expected to be conducive for gradual development, and a tropical depression could form by the middle of next week well south of the southwestern coast of Mexico.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 5 days…medium…60 percent

Interesting: What You See in This Famous Optical Illusion Could Reveal How Old You Are – Do you see an old woman or a young woman?

They are both trapped in this famous optical illusion that first appeared on an 1888 German postcard and was later adapted by British cartoonist William Ely Hill, who published it in a humor magazine in 1915 with the title, “My Wife and My Mother-in-law.” But who you see first could be affected by how old you are, according to a new study published August 23 in the journal Scientific Reports.

Using Amazon’s Mechanical Turk, an online crowdsourcing platform, 393 U.S. participants between the ages of 18 and 68 were shown the illusion for half a second.

They were then asked if they saw an animal or a person and if they said a person, what the sex was of the person. If the participants answered both questions correctly, they were asked to estimate the woman’s age.

Most people saw the young woman, but then again, there were more younger participants (with only five above 60). But the younger population tended to see the younger woman who is facing away, looking over her right shoulder and the older population tended to see the older woman looking toward the side.

Overall, the younger the participant was, the younger they said the woman was — and as the participants’ ages increased, so too did the age of the woman in the illusion. The youngest 10 percent of participants estimated the woman’s age to be 12.1 years younger than the oldest 10 percent of participants. This could be due to an “own-age bias,” according to the paper.

We process faces from similar ages, more thoroughly and holistically than those of other ages, they wrote. Further, the findings could also be in part due to socio-cultural practices in the U.S. that tend to be less inclusive to the elderly, according to the researchers.
