~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Wednesday comments: I’m here at my friend Linda’s place in Corte Madera, CA

Good day everyone, I hope you have a great Wednesday wherever you happen to be spending it.

421am, it’s a clear morning, with a low temperature of 45 degrees.

I fly out of the San Francisco airport this morning, and arrive later this morning on Maui…back from a month long stay here on the west coast…which was fun!

I’ve arrived on Maui and shopped at Whole Foods on the way home, and have set up my computer, so the weather updates will occur regularly…as I was doing on my vacation.

438pm, partly to mostly cloudy here in upper Kula, with quite a bit of haze in our atmosphere.

 

Hawaii’s Broad Brush Weather Overview:  The trade winds will strengthen Thursday and become breezy Friday through the weekend. Rainfall will favor typical windward slopes, with an increase in showers expected this weekend through the first half of next week, as a disturbance aloft passes overhead

Hawaii’s Weather Details: High pressure centered far northeast of the state, and a trough just northwest of Kauai will maintain light to moderate east to east-southeast winds over the western half, and moderate easterly trades over the eastern half of the state through tonight. For tonight, we should see fairly dry conditions with a few scattered over windward areas and isolated showers possible over leeward areas.

As the trough weakens and shifts westward Thursday, high pressure will build over the region, and trade winds will strengthen. By Friday, breezy trades are expected across the state, with locally strong trades over windier areas of Maui County and the Big Island.

As the trades strengthen, showers will also increase primarily over windward and mountain areas. An upper level low approaching the state from the west this weekend, should help enhance the showers and will allow for brief downpours this weekend into early next week.

]Although details are still uncertain, windward and mountain areas could become quite showery through early next week, especially the western end of the state where the greatest instability will exist.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map

Marine Environmental Details: High pressure far northeast of the state will shift south through the rest of the week, and dissipate as a new high pressure system builds to the north. A weak trough to the northwest of the state will shift far northwest of the islands.

In response, moderate to locally strong east-southeast winds will shift to the easterly direction by Thursday, then strengthen to fresh to locally strong Friday. A Small Craft Advisory (SCA) is now in effect for typical windy waters around the Big Island and Maui. This advisory will likely be expanded to include additional waters Thursday and Friday.

Tiny surf will persist along north and west facing shores through Friday. A small northwest swell will is expected to Friday night and peak Saturday bringing small surf along north and west facing shores. Another developing storm will send another small northwest swell late Sunday, peaking early next week, maintaining small surf along north and west facing shores.

Small background south swells will continue, keeping small surf along south facing shores. Small, choppy surf along east facing shores will gradually become rough and choppy Thursday through the weekend as trades return.

Interesting: Impacts of 2020 Red Tide Event Highlighted in New Study

 

In the spring of 2020, a historic red tide event occurred in waters off Southern California. Driven by a bloom of the dinoflagellate Lingulodinium polyedra, this event brought nighttime displays of bioluminescence to beaches along the coast, from Baja California to Santa Barbara.

While the bloom gained international attention for its stunning visual displays, it also had significant negative impacts, including mass mortality among fish and other marine organisms.

Marine scientists from UC San Diego’s Scripps Institution of Oceanography, National Oceanic and Atmospheric Administration (NOAA), and other organizations seized the opportunity to study the unprecedented event and its impacts on marine life, both in the wild and in aquariums.

In a recent study, this multi-institutional team of 34 researchers identified deteriorating water quality — notably prolonged low oxygen conditions — as a significant factor in the mass mortality event. Their findings were published in the journal Elementa, and featured in a special issue focused on the 2020 red tide.
