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%.

 

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.

Hawaii’s Broad Brush Weather Overview…as of 358am Thursday:  Locally strong trades will gradually ease through the rest of the week. Moisture embedded in the trades will allow showers to favor windward and mountain areas through Friday. An overall wetter pattern is expected this weekend as additional moisture is drawn over the island chain.

Hawaii’s Weather Details…as of 358am Thursday: Infrared satellite imagery shows a line of strong thunderstorms along and ahead of a nearly stationary front west of the Hawaiian Islands. This line of thunderstorms has been making its way eastward throughout the night, and is now near the western-most edge of the offshore waters area. High clouds ahead of these storms have begun moving into the western portions of the state, and model guidance and satellite trends suggest increasing coverage of high clouds throughout the rest of the day.

Meanwhile, surface observations show that breezy trade winds are continuing to prevail across the islands, particularly across the typical wind-prone areas of Maui County and the Big Island, as strong high pressure remains centered far north of the state. With that said, winds have largely decreased to slightly below advisory levels, and are expected to continue a gradual decline throughout the day today, as the high to our north weakens. Therefore, the Wind Advisory that was previously in effect for portions of Oahu through the Big Island has been cancelled.

As far as precipitation is concerned, showers will continue to favor windward and mountain areas for the next couple of days, with showers and areas of low clouds embedded within the trades.

A more dynamic weather pattern looks to develop across the islands Friday into the weekend, when the state could reside somewhere along the gradient between trades to the east, and light southeast flow to the west. Model guidance has been fairly consistent in showing the southeast flow in the lower levels could expand moisture over the islands as early as Friday, then stall it over the state through the weekend. There’s also the chance of isolated thunderstorms, first for Kauai and then expanding eastward Friday into Sunday.

It remains to be seen exactly how much instability will set up over the islands. Regardless, the weekend looks to be a wetter pattern where localized flooding and isolated thunderstorms cannot be ruled out, particularly for windward areas. Winds will be lighter throughout this period, with locally strong trades forecast to return to the islands early next week.

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 ??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.
