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 Wednesday comments:  I’m here at my friend Linda’s house in Corte Madera, Marin County, California

It’s clear here in Marin County early this morning. The low temperature was 44 degrees.

I fly to Redmond, Oregon this morning, where my friend Bob will pick me up and drive us back to Bend. We’ve rented a place right on the Deschutes River for a week. We both went to college together, and have been best of friends ever since. I’ll keep updating this website of course, on a daily basis as usual. There will be a time Wednesday that I’ll be away from my computer, although will get right back online as soon as I set up my laptop in Bend.

Weather Wit of the day: Fall – A sad time of year when trees shed their leaves and baseball teams shed their managers

>>> Highest Temperature Tuesday, October 28, 2025 – 101 near Zapata, Texas

Hawaii’s Broad Brush Weather Overview: Light to moderate trades are expected over the next few days with showers favoring windward and mountain areas, particularly near both the eastern and western ends of the state. A brief period of drier weather Friday into the first half of the weekend will be followed by more overcast and wet weather early next week, in response to an early November upper level trough near the state.

Hawaii’s Weather Details: A weakening front is making its way eastward across the North Pacific, situated between two areas of high pressure far north and far northeast of the Hawaiian Islands. This frontal boundary extends into the northern offshore waters, but is expected to weaken over the next 12 to 24 hours. Meanwhile, troughing aloft stretches over the western end of the island chain, but latest satellite imagery shows that most showers and more extensive clouds associated with this feature are located well to the northeast, where much more instability exists aloft.

Locally, precipitable water imagery shows that a pocket of drier air is currently working its way over the smaller islands, while greater available moisture is located near developing troughs near both the far eastern and western ends of the state. Latest satellite and radar imagery supports this, with cloud buildups and a few showers over the Big Island, while low clouds and showers across the remaining islands have have been few and far between.

Some towering cumulus have been noted on satellite imagery over the Big Island. While the probability is low, isolated thunder is possible for the Big Island interior areas. Meanwhile, surface observations and a scatterometer pass show moderate trade winds prevailing across the state.

Guidance suggests that the trough aloft will pinch off into a cutoff upper low, located southwest of the islands by Thursday. As a result, more organized thunder potential and chances of heavy rain will shift far south/southwest of the state. For the islands, showers will favor windward areas, particularly in the overnight through morning periods. Isolated thunderstorms cannot be ruled out again on Wednesday afternoon for the Big Island, though increasing stability should mitigate these chances by Thursday.

Drier air begins to work into the area late in the week, with typical trade wind showers expected Friday into the first half of the weekend, along with light to moderate easterly trades.

An early November cold front may reach the northern coastal waters by this weekend, with winds backing to become more northerly by Sunday. Beyond the weekend, there are significant differences among the various global models regarding the strength of an associated upper trough or potential low aloft. The development of this feature and its evolution would have significant impacts on the rain forecast and thunderstorm chances for early next week.

For now, the forecast has been trended wetter to account for the possibility of a lower level trough/front hanging up north of the state, but isolated thunderstorm chances are very low in the extended forecast for now, since it is too early to determine specifics based on the spread of model solutions at this time.

Fire weather: Increased relative humidity values and moderate trade wind speeds will keep fire weather conditions below critical thresholds for the next several days.

Hawaii’s Marine Environment: A weak front will approach and stall just north of the state into Wednesday. A deepening upper level trough will keep isolated thunderstorms in the coastal waters and offshore waters through Wednesday. During this time a moderate high far northeast of the state will maintain moderate to locally fresh trades. A weak ridge will move into the northern offshore waters later this week, before another front approaches and moves over the state by the weekend.

A reinforcing small, short period north-northwest (330-340 degree) swell has filled in and will keep surf up along north facing shores. An incoming small to moderate, short-period north-northwest (330-350 degree) swell will produce another bump in north shore surf tonight into Wednesday. A new moderate to large, medium to long period north-northwest (330-360 degree) swell could bring above advisory level surf over the weekend along exposed north and west facing shores. Model guidance for north swells have trended towards a low bias so surf heights, and may come in higher than predicted.

Surf along east facing shores will remain small to moderate as the trades ease. South facing shores will continue to see mainly small background swells through the week.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclone

Tropical cyclone formation is not expected during the next 7-days.

 

Caribbean Sea: 

Tropical Cyclone Melissa…is located about 45 miles northwest of Guantanamo, Cuba

According to the NHC advisory number 32A

Melissa is moving toward the north-northeast near 14 mph. A faster northeastward motion is expected during the next few days. On the forecast track, the core of Melissa is expected to move offshore of Eastern Cuba this morning, move across the southeastern or central Bahamas later today, and pass near or to the west of Bermuda late Thursday and Thursday night. Maximum sustained winds are now near 105 mph with higher gusts. Melissa is expected to remain a powerful hurricane when it moves across the Bahamas later today and passes near Bermuda on Thursday night. Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 185 miles. The estimated minimum central pressure is 968 mb (28.59 inches).

Interesting:  Wolves at the Coast: Marine Diets, Ecosystem Impacts

On Prince of Wales Island, Alaska, gray wolves are doing something unexpected: hunting sea otters. This surprising dietary shift appears to have notable implications for both ecosystems and wolf health, but little is known about how the predators are capturing marine prey. Patrick Bailey, a Ph.D. candidate at the University of Rhode Island, is researching these understudied behaviors of gray wolves.

Using a creative mix of approaches — including wolf teeth samples and trail cameras — Bailey is exploring how coastal gray wolves are using marine resources, what this suggests about their behavioral and hunting adaptations, and how these adaptations differentiate them from other wolf populations.

On land, gray wolves are known to play a vital ecological role because of their ability to regulate food webs. “We don’t have a clear understanding of the connections between water and land food webs, but we suspect that they are much more prevalent than previously understood,” says Bailey, a member of Sarah Kienle’s CEAL Lab in the Department of Natural Resources Science. “Since wolves can alter land ecosystems so dramatically, it is possible that we will see similar patterns in aquatic habitats.”
