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.

I’m in Bend with Bob at our vacation rental right on the river, and I just got my laptop and extra monitor set up…I love it here!

It’s 953pm here in Bend, and the temperature is a very chilly 26.6 degrees!

Hawaii’s Broad Brush Weather Overview: Partly cloudy conditions with scattered showers and moderate trades continue through Friday night. Surface winds will weaken Saturday in advance of an approaching boundary (the remnants of a cold front) that will be pushed south into the western islands late this coming weekend. This will bring wetter and cloudier weather Sunday through next Tuesday or Wednesday.

Hawaii’s Weather Details: Radar shows scattered showers, some strong, over the Kona region of the Big Island. A band of enhanced low level moisture was responsible for these showers, and we expected this band to move west of the Big Island tonight. This band may clip the eastern and southern part of Maui County. Otherwise, only isolated windward showers were occurring on the remaining islands.

Currently, upper level ridges to our NW and NE have left a trough over the state. This has resulted in an unstable atmosphere and the possibility of strong showers and perhaps a thunderstorm over the Kona region on the Big Island. Other areas will see scattered showers driven by the trade winds, favoring windward sides as usual. This same pattern will be with us again Thursday. Conditions will become more stable Friday as cold air aloft associated with the upper trough moves away to the east.

The remnants of a cold front will move south toward the state this weekend, likely moving into western islands Sunday morning. Surface winds will weaken late Saturday as the boundary draws near. Precipitation chances will increase as moisture convergence increases on both sides of the boundary. It is currently forecast to stall somewhere over the state, with odds slightly favoring the western half, but models have a difficult time with these features, and confidence in how far east it will go is low. This general pattern should result in a continued increase in showers into early next week over the entire area.

Fire weather: Winds and relative humidity will not meet fire weather thresholds over the next few days. With additional moisture forecast for the weekend, it is unlikely we will see dangerous fire weather through the next week or so.

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 800 miles southwest of Bermuda

DAMAGING WINDS, FLOODING RAINS, AND DANGEROUS STORM SURGE ONGOING IN THE BAHAMAS DUE TO MELISSA

According to the NHC advisory number 35

Melissa is moving toward the north-northeast near 21 mph. An accelerating northeastward motion is expected during the next few days. On the forecast track, the core of Melissa is expected to continue moving near the southeastern or central Bahamas overnight, and is forecast to pass near or to the west of Bermuda late Thursday and Thursday night. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that the maximum sustained winds have increased to near 100 mph with higher gusts. Further strengthening is possible tomorrow before weakening likely begins on Friday. Hurricane-force winds extend outward up to 60 miles from the center and tropical-storm-force winds extend outward up to 185 miles. The estimated minimum central pressure is 970 mb (28.65 inches).

 

Gulf of America:  There are no active tropical cyclone

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

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.”
