Hawaii’s Mountains – Here’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 home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s clear here in upper Kula early this morning, with a cold low temperature of 48.5 degrees.

It was sunny to partly sunny day, along with some volcanic haze, and generally light winds.

Weather Wit of the day:  Beach Erosion – Shore leave

 

Hawaii’s Broad Brush Weather Overview:  Gentle to locally breezy east-southeast winds will persist through mid-week next week, with increasing stability and an influx of drier air helping to limit shower activity.

A slightly stronger easterly flow across the eastern half of the state will maintain a more typical trade wind shower regime, while a weaker east-southeast flow will bring more of a hybrid shower pattern to the western half. Rain chances will increase from the west late next week.

Hawaii’s Weather Details:  Current radar and satellite imagery show scattered showers concentrated across the western end of the state, and moving in a southeast to northwest direction on the east-southeast trades. This is allowing a few showers to impact leeward areas of Oahu and Kauai, in addition to the more typical trade wind windward showers.

Gentle to locally breezy trade winds will persist as high pressure strengthens to the northeast and fills in across the state. With the increasing stability from this surface ridge, and weak mid level ridging building in from the west, combined with drier air filtering in on the trades, shower activity should be minimal through the weekend.

As the island chain remains on the southwestern periphery of the surface high through the weekend and into next week, trades will generally be out of the east-southeast. Winds across the western end of the state will become more light and variable…typically displaying more of a southerly component, while easterlies across the eastern end of the state will be slightly stronger.

The weaker winds across the western half may allow for isolated sea breeze activity, with afternoon clouds and showers forming over a few leeward and interior areas, and the stronger winds across the eastern half will yield a more typical trade wind weather regime, with showers favoring windward areas overnight and leeward slopes each afternoon.

The east-southeast flow for the western half of the state may also allow island plumes (downstream convergence from island terrain) to bring showers to leeward areas at times. As mid-level ridging edges in from the west and strengthens through mid-week next week, overall shower development will continue to be suppressed, but periodic pockets of moisture may bring brief increases in shower activity.

Hawaii’s Marine Environment:  A weak and nearly stationary surface ridge over the waters just N of Kauai will shift north and become oriented E-W by late Saturday. The ridge will then hold through the middle of next week. This will usher in moderate to fresh east winds over Maui and Big Island waters. Elsewhere, light to moderate ESE winds will prevail.

A lingering medium period NE swell and a new long-period northwest swell have combined to bring high surf to most exposed Hawaiian shorelines. The NE swell will continue to decline even as the NW swell reaches its peak. The most recent observations from the Hanalei buoy (51208) indicate that the NW swell is building in slightly above model guidance. A High Surf Advisory (HSA) is in effect for east, north, and west facing shores. The HSA for north and west facing shores will likely be extended through Saturday.

The long-period northwest swell mentioned above is expected to generate high surf heights along north shores of Niihau, Kauai, Oahu, Molokai, and Maui. A slightly smaller NW swell is expected from Saturday night into Monday. A potentially larger WNW swell is looking increasingly likely from between Tuesday and Wednesday night of next week.

No significant surf is expected along south facing shores in the near term, though a small south swell is possible around the middle of next week.

A Small Craft Advisory (SCA) for high seas remains in effect for waters exposed to the increasing NW swell and lingering NE swell. An SCA has also been issued for the typically windier areas surrounding Maui and the Big Island due to the moderate to fresh east winds that will develop.

Interesting:  Air Pollution Clouds the Mind and Makes Everyday Tasks Challenging

People’s ability to interpret emotions or focus on performing a task is reduced by short-term exposure to particulate matter (PM) air pollution, potentially making everyday activities, such as the weekly supermarket shop, more challenging, a new study reveals.

Scientists discovered that even brief exposure to high concentrations of PM may impair a person’s ability to focus on tasks, avoid distractions, and behave in a socially acceptable manner.

Researchers exposed study participants to either high levels of air pollution – using candle smoke – or clean air, testing cognitive abilities before and four hours after exposure. The tests measured working memory, selective attention, emotion recognition, psychomotor speed, and sustained attention.
