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.

It’s cloudy…with a low temperature of 40.5 degrees.

I played Pickleball this morning in Mill Valley, and had loads of fun!

It’s cloudy and looks like rain this afternoon, with a cool 59 degree reading on my outdoor thermometer.

Hawaii’s Broad Brush Weather Overview: Breezy to locally windy trade winds will push deep tropical moisture over the state today. Moderate to locally heavy rainfall will possible mainly along windward and mountain areas of Maui and the Big Island this morning, before spreading to the other islands this afternoon. The chance of heavy rainfall will diminish later today, but breezy and showery trades will persist through Thursday.

Mid level drying will limit clouds and showers Friday into early next week. Easing trade winds over the weekend could allow for more of a hybrid land/sea breeze pattern. Drier moderate trades should return Sunday.

Hawaii’s Weather Details: Rainfall totals have been modest with most rainfall located along windward and mountain areas of Kauai, Maui and the Big Island ranging from .10 to .20 inches. An extensive cloud deck and embedded showers which has remained mostly off the eastern shores of the Big Island overnight and is now moving onshore. Radar shows scattered moderate to locally heavy showers moving along windward and mountain areas of Maui County and Big Island.

High resolution model guidance continues to show of rainfall picking up through the morning hours as stronger trade winds pushes a north to south orientated axis of moisture westward. The main chance of locally heavy rainfall remains along windward and mountain areas of Maui County and the Big Island. Some locally heavy rainfall of 1-2 inches per hour could produce nuisance flooding, but so far showers have been very small and brief.

The threat for heavy rain will decrease later today as upper level instability shifts north and west of the state. Winds will near advisory levels for the windier areas of Maui County and the Big Island as a high builds north of the state.

Increasing thick clouds over the Big Island summits could briefly produce light snow accumulations as precipitation increases, however the snow will quickly transition to rain after sunrise. The Winter Weather Advisory currently runs through today and could be extended through Thursday morning, as the deep moisture lingers and overnight temperatures dip to near freezing.

As for the rest of the state, scattered light to moderate showers will mainly focus along the windward and mountain regions as trade wind speeds pick up. Inversion heights are expected to increase throughout the day as the airmass becomes more mixed, allowing showers to become more moderate and spilling over to leeward areas at times. Locally heavy rainfall could be possible later this afternoon into the evening hours.

The strong surface high passing north will maintain breezy trade winds into Thursday. A band of low level clouds currently to the east, is forecast to move over the state during the day Thursday, keeping a rather cloudy and wet trade wind weather pattern in place.

Trade winds are expected to ease Friday into the weekend, as a cold front approaches the state from the far northwest. Mid level drying should limit clouds and showers. A few high clouds may remain as an upper level trough passes north of the state Friday. A hybrid trade wind and sea breeze pattern could develop Saturday, as winds relax allowing for clouds and showers to develop along leeward and interior areas and low level moisture from the dissipating front moves over the state.

However, cloud heights and showers will continue to be limited due to dry mid levels. The greatest chance of showers will be around Big Island where lingering moisture will be the deepest. Drier and more stable conditions will fill in Sunday into early next week, as mid to upper level ridging builds over the state and moderate trades return.

Fire weather:  Critical fire weather conditions are not expected through the forecast period. Periods of heavy rain remain possible over Maui County and the Big Island. Gusty trades continue into Thursday, with winds ease below critical thresholds thereafter. Lingering moisture will keep relative humidities above critical thresholds.

Hawaii’s Marine Environment: Moderate trade winds will increase. The weakening front to the north is not expected to push much farther east, and northeast winds are already increasing, as the strong surface high behind the front is starting to exert influence. As the front dissipates and the surface high moves north of the state, expect trade winds to ramp up, eventually reaching near gale strength in the Alenuihaha Channel.

A Small Craft Advisory (SCA) is in effect for the typical windy waters around the Big Island and Maui and expands to cover all waters through Thursday as trades rapidly build. The high will be pushed to the east by a North Pacific front late Thursday and Friday, leading to a gradual decline in the trades. Trades may decline further this weekend as the front passes north of the islands.

A northwest swell is moving in and will gradually increase surf along exposed north and west shores from Kauai to Maui. A High Surf Advisory may be needed as the swell shifts out of the north-northwest and continues to build. The northwest swell will be accompanied by a small to moderate north swell aimed primarily west of Kauai, while building trades produce increased wind waves.

The combined seas from all of these sources will contribute to the need for the SCA. The north-northwest swell will gradually decline Thursday and Friday, with another northwest swell pushing surf back near the advisory level Saturday.

East shore surf will be on the rise into Thursday, primarily from increased short period trade wind swell, though the western end of the island chain could also experience a brief north (350-010 degrees) swell. As mentioned above, this north swell will be primarily aimed west of Kauai, but some wrapping energy could push east shores of Kauai near the High Surf Advisory level. The north swell will rapidly fade on Thursday, when peaking trade wind swell will produce surf just below the advisory level on east shores of all islands. East shore surf will decline through the weekend, as trades weaken over and upstream of the islands.

For south shores, tiny background south swell energy will persist.

Interesting: Critically Endangered Penguins Are Directly Competing with Fishing Boats

A new study led by the University of St Andrews, has found that Critically Endangered African penguins (Spheniscus demersus) are significantly more likely to forage in the same areas as commercial fishing vessels during years of low fish abundance, increasing competition for food and adding pressure to a species already in crisis.

Published in the Journal of Applied Ecology, the research introduces a novel metric called “overlap intensity” which for the first time, measures not just the extent of shared space between penguins and fishing vessels, but how many penguins are actually affected by this overlap.

The African penguin population has plummeted by nearly 80% in the past three decades, in part due to competition with the local fishery targeting sardines and anchovies a key prey for the penguins.
