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. 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 home here in upper Kula, Maui, I hope you have a great Tuesday wherever you happen to be spending it.

505am, it’s mostly cloudy and relatively warm early this morning…the low temperature here at my Kula weather tower was 61 degrees.

854am, the clouds are beginning to break up, with sunshine coming out strongly…and muggy.

1210pm, it’s partly cloudy, with lower level cumulus and stratocumulus, in addition to some high Cirrus now too.

549pm, partly sunny in general here in Maui County, with a bit of haze in our atmosphere. My high temperature here in Kula  was 82.5 degrees, and it has dropped to 75.9 at the time of this writing. Dry, dry, dry.

848pm, the clouds are slowly clearing, AND we have a wonderfully bright Harvest full moon rising in the east! The temperature is very slowly dropping, and at the time of this writing, my outdoor thermometer is reading 64.2 degrees.

 

Hawaii’s Broad Brush Weather Overview:  Moderate to locally fresh trade winds will hold through the week. A drier trade wind pattern will continue Wednesday through Saturday, with light to moderate showers focused over windward slopes.

Hawaii’s Weather Details: The area of moisture that moved through the state yesterday is now well west of the state, and we should return to our typical trade wind weather for rest of the week. A High sitting far north of the state should weaken some over the next several days, and will result in the trade winds weakening a touch. Overall, we should see moderate to locally breezy trade winds hold through the weekend, with a decrease possible early next week.

As far as rainfall, we should see our typical dry season weather, with mostly dry conditions across leeward areas for the rest of the week, with some scattered showers over windward areas during the early mornings and overnights.

By early next week, global models are showing an upper level low dropping southward, and within the vicinity of the state around Monday. At this time, it is too early to tell whether or not this will bring any unsettled weather to the state.

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 Map / Vog map animation

Hawaii’s Marine Environment:  High pressure north of the state will maintain moderate to locally strong trade winds through Wednesday. The trades may ease off ever so slightly Thursday and Friday, as the high to the north weakens, before rebounding back to moderate and locally strong levels this weekend. A Small Craft Advisory (SCA) is now in effect for the typically windy waters around the Maui and the Big Island through 6am Thursday.

East shore surf will hold near seasonal levels through Wednesday, then slowly lower Thursday through early next week. A mix of southeast, south and southwest swells will keep some small surf rolling into south facing shores through the weekend. A slight bump in south shore surf is possible early next week, as a slightly larger southwest swell moves into the islands. North shore surf will remain very small through the weekend. A nice bump in north shore surf is possible early next week, as a northwest swell arrives.

The combination of high astronomical tides and water levels running around 0.6 to 0.8 feet higher than predicted will produce localized coastal inundation around the time of high tide. A Coastal Flood Statement remains in effect highlighting potential impacts.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclon

>>> Central Subtropical Atlantic

There’s an area of disturbed weather being referred to as the Remnants of Gordon

Disorganized showers and thunderstorms over the central tropical Atlantic are associated with the remnants of Gordon. This disturbance is forecast to interact with a non-tropical low to its north while moving north-northeastward at 5 to 10 mph during the next couple of days. Environmental conditions could become more conducive for development later this week, and a tropical depression or storm could re-form in a few days while the system moves slowly northward over the central subtropical Atlantic.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 7 days…medium…60 percent

Caribbean Sea:  There are no active tropical cyclone

>>> Northwestern Caribbean Sea:

An area of low pressure could form this weekend over the western Caribbean Sea. Thereafter, some slow development of this system is possible through early next week while the system moves slowly to the north or northwest over the northwestern Caribbean Sea.

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

Gulf of Mexico: There are no active tropical cyclone

Northeastern Pacific: There are no active tropical cyclone

Here’s the link to the National Hurricane Center (NHC)

North Central Pacific:  There are no active tropical cyclone

Northwest Pacific Ocean: 

Tropical cyclone 15W (Pulasan), is located approximately 396 NM southeast of Kadena AB, Okinawa

Southwest Pacific Ocean:  There are no active tropical cyclones

North and South Indian Ocean:  There are no active tropical cyclones

Arabian Sea:  There are no active tropical cyclones

Interesting:  New Filtration Material Could Remove Long-Lasting Chemicals from Water

Water contamination by the chemicals used in today’s technology is a rapidly growing problem globally. A recent study by the U.S. Centers for Disease Control found that 98 percent of people tested had detectable levels of PFAS, a family of particularly long-lasting compounds also known as “forever chemicals,” in their bloodstream.

A new filtration material developed by researchers at MIT might provide a nature-based solution to this stubborn contamination issue. The material, based on natural silk and cellulose, can remove a wide variety of these persistent chemicals as well as heavy metals. And, its antimicrobial properties can help keep the filters from fouling.

The findings are described in the journal ACS Nano, in a paper by MIT postdoc Yilin Zhang, professor of civil and environmental engineering Benedetto Marelli, and four others from MIT.
