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 mostly clear with some clouds along the windward side here in Maui County this morning. The low temperature here at my place was 51 degrees.

746am, clouds have increased rather quickly this morning, and it looks like some of them are dropping showers.

Weather Wit of the day: Let me tell you about this kid in the New York City school system. They asked him to list the climatic zones and he said, “temperature, torrid and tow away.”

 

Hawaii’s Broad Brush Weather Overview:  Moderate to locally breezy trades will persist through Sunday, then gradually ease next week, as the high to the far northwest of the island chain weakens. As an upper level low pushes away from the state, mid level ridging and drier air filtering in on the trades will limit shower activity through much of next week.

Hawaii’s Weather Details:  A strong high to the far northwest of the state, and a weaker high to the far east-northeast, are separated by a northeast-to-southwest oriented cold front heading eastward towards the West Coast of the mainland. This pair of highs will continue to bring moderate to locally breezy trade winds to the island chain through this weekend.

As a broad low develops to the distant northeast early in the upcoming week, it will weaken the high to the northwest, relax the local pressure gradient, and bring lighter trade winds to the area. This weaker flow will persist through much of the week and, may allow for sea breeze development across some leeward areas, increasing clouds and bringing a slight chance of rain.

Looking aloft, the upper level low that’s been responsible for enhancing trade wind showers over the last day or two, will gradually push eastward and away from the state over the next couple of days, with mid level ridging building overhead in its wake. As temperatures aloft rise, atmospheric stability will increase over the region, helping to lower and strengthen the low level inversion, putting a lid on some of the shower activity, confining most trade wind showers to windward and mountain areas through early in the week.

In addition, low level moisture will be limited with drier air filtering in on the trades, also helping to limit shower activity. A weak upper level trough/low will develop near the northwestern end of the state mid-week, and sweep across the state on Wednesday. While this feature will introduce some instability aloft, moisture will still be limited, so we shouldn’t see much of an increase in showers at this time. A strong mid level ridge will quickly build overhead in its wake, bringing more dry and stable conditions through the rest of the week.

Hawaii’s Marine Environment:  High pressure off to the distant north-northwest will maintain moderate to fresh trade winds. A brief stint of moderate to locally strong trades is expected tonight, before the high continues to weaken. By Monday, the ridge to the north weakens, keeping gentle to locally fresh trade winds through the first half of next week. A Small Craft Advisory for the windier waters and channels around Maui County and the Big Island has been cancelled.

A small long period south-southwest swell has begun to fill in and will peak before gradually declining through early next week. A similarly-sized long-period south-southwest swell is expected to arrive next Wednesday into Thursday, bringing another boost to south shore surf.

East shore surf will remain near seasonal average through the weekend as trade winds persist, then gradually decline into mid-week as the trades weaken slightly. Surf along north facing shores will remain tiny through early next week. Guidance suggest the north Pacific getting active over the weekend, which will result in an increase to the surf as a small medium period north-northwest swell is expected during the later half of week.

Starting today and lasting into Wednesday, we can expect higher than normal tides, which could lead to some coastal flooding during the peak of high tides in the early afternoon hours. As this elevated tide is expected between the aforementioned south swells, this event will likely have minimal impact.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:  There are no active tropical cyclones

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific:  There are no active tropical cyclones

South of the Southern Coast of Mexico:

>>> An area of low pressure is likely to form early next week several hundred miles south of the southern coast of Mexico. Conditions appear favorable for development of this system, and a tropical depression could form around the middle of next week while moving westward to west-northwestward at 10 to 15 mph.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…high…80 percent

Interesting:  A New Technology for Extending the Shelf Life of Produce

We’ve all felt the sting of guilt when fruit and vegetables go bad before we could eat them. Now, researchers from MIT and the Singapore-MIT Alliance for Research and Technology (SMART) have shown they can extend the shelf life of harvested plants by injecting them with melatonin using biodegradable microneedles.

That’s a big deal because the problem of food waste goes way beyond our salads. More than 30 percent of the world’s food is lost after it’s harvested — enough to feed more than 1 billion people. Refrigeration is the most common way to preserve foods, but it requires energy and infrastructure that many regions of the world can’t afford or lack access to.

The researchers believe their system could offer an alternative or complement to refrigeration. Central to their approach are patches of silk microneedles. The microneedles can get through the tough, waxy skin of plants without causing a stress response, and deliver precise amounts of melatonin into plants’ inner tissues.
