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.

Glenn’s Thursday comments:  I’m here at home in upper Kula, Maui

It’s partly cloudy early this morning here at my place, with calm winds, and a very chilly low temperature of 46.5 degrees , and the relative humidity is 82%.

426pm, had to go down to Kihei and have stitches in my forehead, as the Dermatologist found a spot of skin cancer. Ouch, when I got back home I had the worse pain, can’t remember the last time I had such a feeling! Fortunately, a while back a friend had given me some pain pills, and after about an hour of suffering…it kicked in!

It’s cloudy here in the state, much of which is high cirrus clouds arriving from the west. At the same time, a friend has informed me that it’s raining in Makawao and Haiku…although it’s still dry here at the moment.

 

Weather Wit of the day:  Do you realize that snow is the peanut butter of nature? It’s crunchy, the kids love it and it sticks to the roof of your house.

 

>>> Highest Temperature Thursday, February 19, 2026 – 98 near Hidalgo, TX

Hawaii’s Broad Brush Weather Overview…as of 337pm Thursday:  Breezy trades will gradually ease through the rest of the week. Moisture embedded in the trades will allow showers to favor windward and mountain areas into Friday. An overall wetter pattern is expected this weekend, as additional moisture is drawn over the island chain, and an upper level disturbance moves overhead. Strengthening trades early next week will return a more typical windward and mountain focused shower pattern, followed by more stable conditions by mid to late next week.

Hawaii’s Weather Details…as of 337pm Thursday:  Radar and satellite imagery shows isolated to scattered showers moving into most windward areas on breezy to locally windy trade winds. The motion of these showers continues to indicate a slight southeasterly component in the low-level steering flow, a pattern that is expected to persist for the next several days. Meanwhile, a line of thunderstorms has remained active along a stationary front west of the state, sending high-level cirrus clouds streaming over the island chain. These high clouds are expected to linger through tonight into Friday.

An area of deeper moisture can be seen upstream of the state on satellite, and is forecast to move across the islands overnight into Friday. As this moisture arrives, an increase in windward and ;mountain showers is expected late tonight into Friday morning, even as trade winds gradually ease and veer slightly.

Looking ahead to the weekend, in addition to the moisture arriving on the trades, an axis of deep moisture will approach from the west, as an upper-level trough swings overhead. The combination of increasing moisture and instability will bring the potential for localized flooding and isolated thunderstorms late Friday afternoon into Saturday, particularly across the western end of the state.

Winds will be lighter during this period. While the overall pattern is somewhat complex and has posed forecast challenges, confidence is increasing that Kauai could see periods of moderate to locally heavy rainfall, capable of producing localized flooding. As a result, a Flood Watch has been issued for Kauai County from 3pm Friday through 6am Saturday.

Beyond the weekend, model guidance suggests that between Sunday night and Tuesday, moisture pooled along a horizontally-oriented frontal boundary will shift southward down the island chain, as high pressure builds north of the state between two nearby lows. This boundary will bring another increase in windward and mountain showers as it moves through, followed by strengthening trade winds. By the latter half of next week, mid-level ridging is expected to build overhead, supporting a more stable pattern with moderate to breezy trade winds.

High Surf Advisory until 6pm this evening for east facing shores
of Kauai, Oahu, Molokai, Maui, and the Big Island.
Small Craft Advisory until 6pm this evening for all Hawaiian waters

 

Hawaii’s Marine Environment…as of 358am Thursday:  A strong high pressure system to the north and a low pressure system and front just west of the offshore waters, will allow strong to near gale force east to east-southeast winds to blow through Friday. Winds are expected to decrease gradually as the high pressure and front weaken, and then a new high builds in to the distant north by the weekend. A Small Craft Advisory (SCA) is in effect for all coastal waters through this afternoon, due to a combination of winds and seas. This SCA will likely be modified and extended later tonight to include the typical windy areas as the winds decrease. The trade winds and seas are then expected to gradually lower Friday through the weekend.

Unsettled weather is expected Friday through the weekend, as a mid and upper level trough is forecast to move over the islands from west to east. Isolated thunderstorms can be expected around Kauai and Oahu waters by Friday afternoon, then spread to the rest of the islands by the weekend. Windward waters currently appear to have the highest chance of thunderstorms. Winds look to be lighter to the south of each island, and fresh to the north of each island on Friday. Winds then become light and variable Saturday through Sunday.

Surf will hold relatively steady along east facing shores before gradually decreasing tonight through the weekend as winds decrease.

Surf along north and west facing shores will remain well below seasonal levels through the weekend, and surf along south facing shores will remain small.

Forerunners from a large, long-period north to north-northeast swell are forecast to arrive Sunday night, then rapidly build to near warning levels along north facing shores Monday through Tuesday. Also due to the northerly direction, elevated surf heights are expected along west Maui and west Big Island near Kua Bay. Surf heights are expected to reach advisory threshold for west Big Island on Monday and could reach advisory threshold for west Maui as well. Lastly, due to the large swell and northerly direction (010-030 degrees), heavy surges are expected along north facing harbors such as Kahului and Hilo harbors.

Interesting:  Betting on Floating Ports

Building a port on land takes time. On water, the job can be done quickly. Hagbart Skage Alsos and his research colleagues at SINTEF are investigating how to build floating ports.

Ports in Northern Europe are full. Offshore wind and other projects need a port for everything that requires transport to those construction sites. Such as when a landslide obliterates and closes a road or railway for a long time. A solution has to be found – and SINTEF researchers think running test scenarios in the fjord is the place to start.

“The idea of a floating infrastructure isn’t entirely new. Japan has talked about floating airports, and Norway has carried out projects with long floating bridges,” Alsos says.

Floating ports are being tested out in a large test basin in Trondheim.
