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 Monday comments:  I’m here in Bend, Oregon, visiting my good friend Bob Earle, who is a professor of Physical Geography and GIS at the local college. I hope you have a good Tuesday wherever you happen to be spending it.

It’s partly cloudy here in Bend, with a low temperature of 30.5 degrees in Bob’s backyard in NW Bend.

Bob and his cousin Pat and I walked to the Commons this morning, and had coffee together. We then walked through interesting neighborhoods on the way back, and enjoyed looking at Christmas decorations, and all the various deciduous trees with their leaves turning color.

 

Hawaii’s Broad Brush Weather Overview:  Breezy trade winds today will strengthen and become windy through the end of the week. Showers will focus along windward and mountain exposures, reaching the leeward sides of the smaller islands as winds strengthen.

Hawaii’s Weather Details:  High pressure systems far north and northeast of Hawaii are separated by a cold front across the northeast Pacific. The northern one is a strong high, and resulting in robust trade winds across the islands. Atmospheric soundings at Hilo and Lihue show a strong 7,000 foot inversion in place across the area.

Satellite and radar imagery show a band of showery clouds over and just upstream of Oahu to Maui. Expect light and quickly passing showers mainly for windward slopes of these islands (and Kauai with time), with isolated showers leeward. This band of clouds is expected to slide west of the state tonight, which will be followed up by another band late tonight into Thursday.

The high to the north will take over while the front weakens and is pushed southward by the northern high building behind it. Trade winds speeds will begin to increase by Wednesday and continue strengthening through the end of the week. Winds are forecast to peak late Friday into Saturday with some portions of the state reaching advisory levels as early as Thursday.

Peak winds are in conjunction with the arrival and departure of the remains of the dissipated front mentioned earlier. An increase in cloud cover and showers are expected as this feature passes through, with both windward and leeward sides of the islands receiving rainfall. Wind speeds will slowly taper down Sunday into Monday (but still remain fairly breezy) with continuing showers focusing windward and mountains.

Hawaii’s Marine Environment:  A broad ridge of high pressure remains established north of the islands, and is generating fresh to locally strong trades. This ridge will strengthen through the rest of the week, translating to strong to near gale force trades developing Wednesday into Thursday and possibly reaching gale force Friday into the weekend. The existing Small Craft Advisory remains in effect and will eventually require an expansion in coverage, as trades strengthen and seas become elevated.

The existing northwest (320 degrees) swell will hold steady. A larger northwest (320) swell will fill in later tonight, keeping surf elevated. This swell is forecast to peak above the High Surf Advisory threshold for north and west facing shores Wednesday, and may near High Surf Warning thresholds late Wednesday before fading Thursday. This swell will mix with a small north-northwest (340-350) swell that will also peak tonight into Wednesday.

Rough and choppy surf along east facing shores will gradually become more elevated during the second half of the week, as strong trades further develop locally and upstream. Surf along east facing shores is expected to build to the HSA thresholds Thursday into Friday, and hold into the weekend.

Surf along south facing shores remains small through the period except with a small rise expected Wednesday.

Peak monthly tides are forecast during the Nov 14th to Nov 18th period. This along with elevated seas due to strong trades and fading large northwest swell, will exacerbate coastal inundation impacts, particularly for vulnerable locations during early morning high tides.

 

                          

 

 

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:   There are no active tropical cyclones

>>> Central and Western Caribbean Sea:

Invest 99L

Showers and thunderstorms over the central Caribbean Sea have become more organized in associated with a broad area of low pressure. Environmental conditions appear conducive for development, and a tropical depression is likely to form within the next couple of days while the system moves slowly westward into the western Caribbean Sea. Afterward, further development is likely while the disturbance meanders over the western Caribbean Sea through the weekend. The system is forecast begin moving slowly northwestward by early next week. Interests across the western and northwestern Caribbean Sea should monitor the progress of this system. Regardless of development, heavy rains are expected over Jamaica and portions of Haiti during the next day or so.

Interesting:  Measurements From ‘Lost’ Seaglider Offer New Insights Into Antarctic Ice Melting

New research reveals for the first time how a major Antarctic ice shelf has been subjected to increased melting by warming ocean waters over the last four decades.

Scientists from the University of East Anglia (UEA) say the study – the result of their autonomous Seaglider getting accidentally stuck underneath the Ross Ice Shelf – suggests this will likely only increase further as climate change drives continued ocean warming.

The glider, named Marlin, was deployed in December 2022 into the Ross Sea from the edge of the sea ice. Carrying a range of sensors to collect data on ocean processes that are important for climate, it was programmed to travel northward into open water.

However, Marlin was caught in a southward-flowing current and pulled into the ice shelf cavity where it remained, with its sensors on, for four days before re-emerging. During this time the ‘lost’ glider completed 79 dives, taking measurements of the water within the cavity to a depth of 200 metres, right up to base of the overlying ice shelf.
