Hawaii’s Mountains – Here’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 Wednesday comments:  I’m home here in upper Kula, Maui, I hope you have a great Wednesday wherever you happen to be spending it.

605am, it’s mostly clear early this morning…the low temperature here at my Kula weather tower was 55.5 degrees.

239pm, it’s sunny this afternoon, although not too hot up here in Kula…compared to the 90 degree high down in Kahului at the AP.

8pm, the still very large September full moon is rising out of the eastern horizon…it’s incredibly bright and large!

845pm, clear with a quickly cooling temperature of 61.1 degrees at the time of this writing here at my place.

 

Hawaii’s Broad Brush Weather Overview:  A dry weather pattern under gentle to breezy trade winds will prevail the next several days. Occasional showers will focus along windward-facing terrain, with more frequent shower activity occurring during the overnight hours. There are increasing chances for more statewide rain early next week, as an upper low develops in the vicinity of the state.

Hawaii’s Weather Details:  Satellite and radar imagery this morning shows an area clouds and showers moving mainly Oahu and Kauai. This enhanced area of showers will continue to provide an increase in clouds and showers through the morning hours, as it moves from east to west. Overnight rainfall totals along windward areas have reached at least .20 of an inch, with some select leeward areas receiving .01 of inch.

A high sitting far north of the state will continue to generate moderate to locally breezy trade winds through the weekend, with only some slight variations as the high meanders north of the state and fluctuates in strength. The high is expected to weaken by the weekend into early next week, but winds may stay breezy locally due to a disturbance passing south of the islands keeping the gradient tight.

As far as rainfall, expect a drying trend later this afternoon, due partially with the diurnal pattern and a drier, more stable air mass filtering in. Precipitable water vapor imagery shows the tail-end of above normal moisture currently passing over the state, with near to below normal moisture levels upstream, which will start to filter in today. In addition, a trough will push west today while more stable conditions build in, limiting cloud depth.

The GFS model shows an upper level low dropping southward within the vicinity of the state around Monday, while the EC model has the low lingering just west of the state. These differences continue to create some uncertainty with the forecast during this time. If the GFS scenario pans out, it could mean we will see an increase of shower coverage as early as Sunday.

Hawaii’s Marine Environment:  High pressure north and northeast of the state will keep moderate to locally strong trade winds in place through the weekend. A Small Craft Advisory (SCA) is now in effect for the typically windy waters around Maui and the Big Island through 6am Friday. The SCA may eventually need to be extended through the weekend.

East shore surf will hold near seasonal levels through Thursday, then slowly lower Friday through early next week. A mix of southeast, south and southwest swells will keep small surf rolling into south facing shores through Monday.

A slight rise in south shore surf is possible around Tuesday or Wednesday of next week, as a slightly larger southwest swell moves through. North shore surf will remain very small through the weekend. A nice bump in north shore surf is possible Tuesday and Wednesday of next week as a northwest swell arrives.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

>>> Central Subtropical Atlantic

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

An area of disorganized showers and thunderstorms located over the central tropical Atlantic is associated with the remnants of Gordon. This system is forecast to interact with another area of low pressure to its west while moving north-northeastward at 5 to 10 mph during the next couple of days. While environmental conditions appear only marginally conducive for additional development by the end of this week, a tropical depression or storm could still re-form in a few days while the system moves slowly northward over the central subtropical Atlantic.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 7 days…medium…40 percent

>>> Central and Western Subtropical Atlantic

Shower and thunderstorm activity has increased tonight with a well-defined area of low pressure located a few hundred miles to the northwest of the remnants of Gordon. Environmental conditions appear only marginally conducive, but some additional development of this system is possible as it meanders over the open waters of the central or western Subtropical Atlantic though early next week.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…low…20 percent

Caribbean Sea:  There are no active tropical cyclone

>>> Northwestern Caribbean Sea and Southeast Gulf of Mexico:

A broad area of low pressure could form late this weekend or early next week over the western and northwestern Caribbean Sea. Thereafter, some slow development of this system is possible through the middle of next week while it moves slowly to the north or northwest over the northwestern Caribbean Sea or the southeastern Gulf of Mexico.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…40 percent

Gulf of Mexico: There are no active tropical cyclone

Northeastern Pacific: There are no active tropical cyclone

Interesting:  Researchers Working to Keep Electric Vehicles Charging, Even When the Lights Go Out

It’s stormy and the power just went out. With no electricity flowing to your electric vehicle, you’re stranded for the night.

“It’s a double problem,” said Zhaoyu Wang, an Iowa State University professor of electrical and computer engineering. “There’s no electricity. And you can’t go anywhere.”

The federal government’s Joint Office of Energy and Transportation is asking Wang and his research collaborators to study potential solutions. The work will be supported by a two-year, $1.2 million grant. Research partners will also contribute $300,000 of cost-share funding.
