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 Saturday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s partly to mostly cloudy with localized showers here in Maui County early this morning. The low temperature at my place was 59 degrees…with a relative humidity of 84%.

935am, lots of large clouds around, with showers falling locally…and rainbows!

I played 4-games of Pickleball in Haiku, and then shopped at Mana Foods in Paia, on the way home to here in upper Kula.

Weather Wit of the day: Do you realize that Detroit is the only city which knows how to handle its air pollution problem? It dumps its air into the tires of new cars, and quietly ships them out of town.

Hawaii’s Broad Brush Weather Overview: An upper-level low currently northeast of the Hawaiian Islands will move south over the next several days, which will maintain relatively unstable conditions. Moderate to locally breezy trades will also continue into tonight. This combination will continue to bring enhanced showers and a slight chance of thunderstorms throughout the next couple of days.

Hawaii’s Weather Details:  Satellite imagery continues to show thunderstorm activity north and west of Kauai and Niihau, which is forecast to move further westward and away, while extensive cloud cover blankets Maui and the Big Island.

Observations over the past few hours have indicated that light precipitation has fallen over the Hawaiian Islands, with the heaviest fallen over parts of Maui and western portions of Molokai. Trends suggest that additional precipitation is expected, primarily across the windward and mountain areas for all islands through early Sunday morning before clearing during the day.

Moderate to locally breezy trades continue today into tonight, maintaining enhanced shower activity across windward and mountain areas. Winds thereafter begin to ease to a light to locally moderate pattern persisting through mid-week. Trades strengthen toward the latter end of next week through the weekend.

Model guidance of the GFS and ECMWF also continues to depict an upper-level trough will remain over the vicinity of the Hawaiian Islands, sustaining unstable conditions. Within this trough remains two individual closed low circulations that have been steering the state’s weather these last couple days. One is situated to the west of the island chain and will move westward away, while the second is positioned northeast of the islands.

This second closed low will end up centered very close to the islands by Wednesday, however, latest guidance has depicted the circulation to stay east of the islands at this time, while propagating southward through the remainder of the outlook period.

Much of the coldest air aloft has been forecast to remain north of the island chain, limiting any thunderstorm potential, however, model guidance does hint at periods of enhanced shower activity throughout the week, in conjunction with the wet trades pattern.

Fire weather:  Wind speeds and afternoon minimum humidity levels will remain below critical fire weather thresholds through the forecast period. Unstable conditions will continue to produce wet weather across the state through early next week. Temperature inversion heights near Maui and the Big Island will range from the 8,500 to 9,500 feet for the time being.

Hawaii’s Marine Environment:  Moderate to locally strong trades will remain in place over the Hawaiian coastal waters. Trades then weaken into the moderate to locally fresh range through early next week. An upper low north of Kauai will continue to drift over the northern waters through the weekend, keeping a slight chance of thunderstorms in the forecast.

Two moderate, long-period NW and NNW swells moving across the waters will maintain elevated surf along N and W facing shores and then trend down on Sunday. A hurricane force low E of Japan will bring another round of moderate, long-period NW (330 deg) swell into the islands towards the middle of next week, leading to building surf along N and W facing shores. This next long-period swell may reach low-end High Surf Advisory thresholds Wednesday into Thursday.

A series of small, medium-to long-period S to SW swells will filter into the area this weekend keeping surf along S facing shores from going flat. Short-period surf along E facing shores increases slightly on Saturday, due to the stronger trades, then trends down slightly Sunday through early next week.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclone

North Atlantic

>>> A non-tropical area of low pressure is located several hundred miles northeast of Bermuda. There is a slight chance that the system could develop some subtropical characteristics over the next day or so before it turns northeastward into cooler ocean waters on Sunday.

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

 

East of the Windward Islands and the Caribbean Sea

Invest 98L

>>> A tropical wave located several hundred miles east of the Windward Islands continues to produce a broad area of showers and thunderstorms. Earlier satellite wind data indicated the system lacks a closed circulation, but is producing winds of 30 to 35 mph to the north of the wave axis. Environmental conditions appear marginally conductive for slow development over the next couple of days as the system moves quickly westward at 20 to 25 mph, crossing the Windward Islands and entering the Caribbean Sea by early next week. By the middle of next week, the system is expected to slow down over the central Caribbean Sea, where environmental conditions could become more favorable for further development. Regardless of development, this system is expected to bring heavy rainfall and gusty winds to the Windward Islands Sunday and Sunday night.

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

Interesting:  Road Noise Can Actually Make Squirrels Feel Safer, New Study Finds

Human disturbance has a significant impact on the behavior and habitat use of urban wildlife, however, in some situations urban grey squirrels may actually feel safer from predators where our activity is high.

A new study from the University of Exeter, published in Oikos, reveals the paradoxical ways grey squirrels balance risk and foraging in urban environments. Researchers measured how much food squirrels left behind in standardized food patches in different places, which reflects how dangerous they perceived their local surroundings to be. They found that squirrels felt safer from predators near roads when noise levels were consistently loud.

However, squirrels also perceived foraging as more dangerous where noise was less consistent. The findings highlight the complex trade-offs squirrels face in urban environments when balancing the risks and benefits associated with living alongside humans.
