Hawaii’s MountainsHere’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’s Broad Brush Weather Overview:  Trades will give way to southeast winds later today, as an upper level ridge axis moves across the state. Showers will be light and mainly in windward and mountain areas. A weakening cold front will move into the western part of the state Wednesday, but confidence is low on how far into the state it will get. Rainfall chances will increase in western counties Wednesday through Friday, and perhaps throughout the state. There is a chance that increased showers could linger through next weekend.

Hawaii’s Weather Details:  Satellite showed areas of low clouds moving toward the state from the east-northeast under the influence of trade winds this morning. There was just enough moisture for isolated light showers moving into some windward areas, but any precipitation amounts will be light, a few hundredths of an inch at most.

A surface high several hundred miles to our northeast will move farther northeast today, helping to shift our winds around to the southeast. This will begin to increase warmth and moisture into the coming week. Showers will increase slightly later today, and a little bit more Monday and Tuesday.

Things change more significantly Wednesday, when a front will approach from the northwest. Driven by an upper level trough, reaching Kauai County Wednesday morning, then Oahu in the afternoon, and Maui County in the evening. Models diverge at this point, with important differences. Models show some solutions taking the front through Big Island, while others stall it and begin to move it back to the west.

But the speed at which it moves back west, and the amount of moisture associated with the remains of the front, vary amongst the model solutions. At this point, all we can really say is that the chance of precipitation increases from west to east across the state Wednesday into Thursday, with an increased chance of showers likely remaining elevated over some parts of the state beyond Thursday.

Hawaii’s Marine Environment:  High pressure to the north of the state will continue to move to the east as a cold front moves towards the islands. With the high pressure to the north, moderate to locally strong trade winds will continue. As the cold front advances to the east towards the islands, winds will weaken and veer to the southeast. The front is expected to enter the offshore waters Tuesday, and will bring the possibility of thunderstorms to the northern offshore waters Tuesday through Thursday. The front is expected to reach the northwest coastal waters late Tuesday, and move over the central waters Wednesday, where it will linger during the second half of the week.

The new moderate, long period, northwest swell has reached the buoys to the northwest of the islands, and will reach Kauai. This swell will cause surf to rise rapidly along north and west facing shores. A High Surf Advisory (HSA) has been posted for the effected shores of the smaller islands. This swell is expected to peak in the islands, with surf dropping below HSA levels tonight. Another moderate, long period, northwest swell is expected to arrive in the islands Tuesday, and linger through the middle of the week. This swell will maintain elevated surf along north and west facing shores.

The moderate to locally strong trade winds will maintain rough and choppy surf along east facing shores. Additionally, some east facing shores sensitive to northerly swells may be experiencing a slight increase in surf heights as a fading north swell lingers. As winds weaken and veer to the southeast ahead of the incoming front, surf will lower along east facing shores. There are no noteworthy swells for the next few days for south facing shores.

Interesting:  Microplastics Detected in Rural Woodland

Air-polluting microplastics have been found in rural areas in greater quantities than in cities, researchers say.

The study, led by the University of Leeds, detected up to 500 microscopic particles of plastic per square metre per day in an area of woodland during the three-month study – almost twice as much as in a sample collected in a city centre.

Researchers believe trees and other vegetation capture airborne microplastic particles from the atmosphere and deposit them, highlighting the impact that different landscape and weather conditions have on the spread of the particles.

And they say that these unexpected results challenge the assumption that microplastic pollution is mainly an urban problem.
