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 Aloha Friday comments:  I’m here in Corte Madera, California, visiting my good friend Linda.  I hope you have a good Friday wherever you happen to be spending it.

It’s clear here in Marin County, with a very low temperature of 29.5 degrees in Linda’s backyard!

I’ll be taking the 630am Marin Airporter this morning, down to the San Francisco AP, for my flight back to Kahului, Maui. I’ll be picked up by my good friend David Salemme, and we’ll swing by Whole Foods in Kahului for a quick shopping. I’ll be back home to upper Kula by mid-afternoon, at which point I’ll set up my laptop and get back to work updating this website. My good friend Dr. Jeff Kuhn has invited me over to his place, he lives about a mile from me, for a drink and dinner this evening.

 

Hawaii’s Broad Brush Weather Overview:  Moderate to locally fresh trade winds will be weakening today through the first half of next week. Conditions remain fairly stable with passing low clouds and light showers.

Hawaii’s Weather Details:  High pressure far north-northeast will generate moderate to locally fresh trade winds across the islands. Visible satellite shows an area of incoming low clouds to windward Big Island that could bring a some showers over windward slopes.

Scattered clouds across the smaller islands may also bring a few showers mainly to windward slopes. Atmospheric soundings show a dry and stable atmosphere across the state, so any showers that do move onto the islands will be light.

Trade wind speeds will weaken into the weekend, as a cold front approaches then stalls and weakens northwest of Kauai. Expect mostly dry and stable weather to continue into Saturday, with the highest chance of rain along windward slopes during the nighttime and early morning hours.

Winds will shift out of the south by Sunday, but will weaken enough for localized daytime sea breezes and nighttime land breezes Sunday into Monday. Clouds and showers will focus over leeward and interior sections during the afternoons, due to the sea breezes setting up.

A stronger cold front will approach and reach Kauai around next Thursday, then either stall in place or slowly move across the state into next Friday. Winds will strengthen out of the south and southwest beginning Sunday night across Kauai and Oahu, but remain mostly in the land and sea breezes pattern over Maui County and the Big Island.

A shower band ahead of the front will make its way through the southerly flow by Wednesday and may impact Kauai and/or Oahu into Wednesday night. The front will arrive on Kauai Thursday in a fairly weak state before stalling and dissipating over the central part of the state next weekend. There’s till some model differences with the with the timing and location of the front as it reaches Hawaii.

Fire weather:  Critical fire weather conditions not expected through early next week, as winds remain below warning thresholds. Daytime relative humidity may briefly touch critical levels over drier leeward areas into next week.

Hawaii’s Marine Environment:  Moderate to locally fresh northeast winds will linger. Trade wind speeds will weaken into the weekend as a front approaches then stalls and weakens northwest of the coastal waters. Winds will shift out of the southeast by Sunday, but will weaken enough for localized daytime sea breezes and nighttime land breezes Sunday into Monday.

A large to extra-large west-northwest (310-320 deg) swell will peak above High Surf Warning (HSW) level criteria late today into early Saturday. Observations reflects energy filling in from the northwest, translating to forerunners hitting the nearshore PacIOOS buoys early Friday.

Expect the potential for periodic over-topping of vulnerable coastal roadways, wave runup to coastal properties especially around high tide early Saturday morning. A Small Craft Advisory (SCA) for high seas over a majority of the coastal waters, and a High Surf Warning will hold through Saturday.

Due to the westerly component of this swell a High Surf Advisory (HSA) has been issued for west-facing shores of the Big Island through Saturday. A gradual downward trend will follow over the weekend, with surf potentially dipping below the advisory levels by the end of the weekend. Into the extended forecast, a stretch of elevated surf is expected with overlapping northwest pulses ranging from large to extra-large surf.

Surf along east facing shores will remain elevated through the weekend, due to the lingering north-northeast swell.

Surf along south facing shores will see an increase through the first week of December from the southwest, in a series of consecutive pulses, ranging from small to moderate surf with the peak days looking to be next week Monday and Tuesday.

Interesting: Conserving Nature can Shield Cities From Floods

Picture a forest meadow, a patch of wetland or a stretch of grassland. These quiet spaces, so often overlooked, could be the key to protecting Canada’s cities from floods. A UBC study finds that conserving just five per cent of watersheds (two per cent of Canada’s land) could shield more than half of urban floodplains, safeguarding millions.

Study author and UBC forestry expert Dr. Matthew Mitchell calls this research the first of its kind in Canada to explore how ecosystems function as natural flood buffers.

When these areas are preserved, they absorb water, slow runoff and reduce the strain on flood defences. All of this could mean fewer dams, less infrastructure and fewer floods.
