Glenn’s Tuesday comments: I’m home here in upper Kula, Maui, Hawaii

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

501am, it’s partly cloudy this morning here in Kula, with a low temperature of 54.5 degrees at my place.

855am, most of the clouds that are over Maui County are of the high cirrus variety, which lit up a pretty pink at sunrise.

1204pm, partly to mostly cloudy over and around the mountains, with sunny to partly sunny conditions down along the beaches. The temperature here at my place is 71.9 degrees, compared to the warmer 85 down at the Kahului AP, and an even warmer 88 at Maalaea Bay. This of course is in contrast to the much cooler 46 degrees atop Mauna Kea on the Big Island!

504pm, there’s very little wind here in upper Kula, and at the same time it feels rather muggy, although my instrument doesn’t show but 63% relative humidity. My high temperature today reached a fairly pleasant 74 degrees here at my Kula weather tower.


NOAA predicts a below-normal 2024 central Pacific hurricane season

The 2024 central Pacific hurricane season outlook from forecasters at NOAA’s Central Pacific Hurricane Center and NOAA’s Climate Prediction Center, calls for 1 to 4 tropical cyclones across the central Pacific Hurricane region.

A near-normal season has 4 or 5 tropical cyclones, which include tropical depressions, tropical storms and hurricanes. Overall, there is a 50% chance of below-normal tropical cyclone activity.

The outlook also indicates a 30% chance of a near-normal season and 20% for an above-normal hurricane season across the central Pacific hurricane region. The central Pacific hurricane region is located north of the equator
between 140°W and the International Date Line

“Hurricane season in the central Pacific region is likely to be below average this year,” said Matthew Rosencrans, lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center, a division of NOAA’s National Weather Service (NWS).

“A key factor influencing our forecast is the predicted arrival of La Nina this summer, which typically contributes to less tropical cyclone activity across the central Pacific Ocean basin.” As one of the strongest observed El Ninos nears its end, NOAA scientists predict a quick transition to La Nina conditions. La Nina typically increases wind shear in the central Pacific region, making it harder for storms to develop. Forecasters look at a combination of atmospheric and oceanic conditions, climate patterns and climate models to develop the outlook.

The hurricane season outlook is a general guide to the overall seasonal tropical cyclone activity in the central Pacific basin and does not predict whether or how many of these systems will affect Hawaii. The central Pacific hurricane season begins June 1 and runs through November 30.


Hawaii’s Broad Brush Weather Overview:  High pressure to the north will maintain moderate to locally breezy trade winds through early next week. Showers will favor windward slopes and coasts, especially during the overnight and early morning hours. A trough aloft will move over the islands Friday through early next week, bringing an increase in trade wind shower coverage and intensity.

Hawaii’s Weather Details:  Weather maps show a trough of low pressure is located west-northwest of Kauai, while a high is centered far north of the state. Moderate to locally breezy trade winds prevail, strongest over the eastern end of the state.

Infrared satellite imagery shows a mix of high and low clouds resulting in partly to mostly cloudy conditions. Radar imagery shows isolated to scattered showers moving into windward slopes and coasts, with mostly dry conditions in leeward locales.

High pressure will build eastward and strengthen well north of the state during the next couple days, while the trough of low pressure remains nearly stationary west of the island chain. Wind speeds will change little, with the trades holding in the moderate to locally breezy range.

The trough will shift westward and dampen out Thursday and Friday, with high pressure northeast of the state then settling southward and closer to the islands through the weekend. This should give a slight boost to the trade wind speeds, with moderate to breezy conditions holding in place through early next week.

Meanwhile, relatively dry trade wind weather should prevail during the next few days, with showers favoring windward slopes and coasts particularly at night and during the early morning hours. Troughing aloft appears to move over the islands Friday and linger through early next week, bringing an increase in trade wind shower coverage and intensity.

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

Hawaii’s Marine Environment:  Fresh to strong easterly trades will continue through the week, as the surface ridge remains positioned north of the state. The strongest winds are expected over the windier waters and channels from Oahu to the Big Island, supporting the Small Craft Advisory being expanded.

The winds over the Kauai waters will fluctuate between east and east-southeast through Wednesday, due to a persistent surface trough to the west. A shift out of the east-northeast is expected beginning around Thursday, as the trough weakens and drifts away from the area.

Surf along exposed south-facing shores will remain small throughout much of the week, due to a combination of south-southwest and southeast swell energy. An upward trend is expected from Friday through the first week of June, due to an active pattern evolving within our swell window near New Zealand.

Satellite passes over the past couple of days reflected the potential for the weekend, showing a broad swath of gale-to storm-force winds with high seas focused at the state within the 190-200 degree directional bands. This will mark the beginning of a long-lived event, with additional reinforcements expected within the same area over the next several days.

Surf along exposed east-facing shores will remain small and choppy throughout the week as the trades persist.

Surf along north-facing shores will remain near the summertime average each day. Guidance depicts a small swell arriving early next week from a gale that is forecast to track northeastward over the far northwest Pacific near the Kuril Islands.

Interesting:  Future Climate Impacts Put Whale Diet at Risk

A new study led by Griffith University predicts future climate change impacts could disrupt the krill-heavy diet that humpback whales in the southern hemisphere consume. 

Dr Jasmin Groß, who conducted the study as a PhD candidate at Griffith’s Center for Planetary Health and Food Security analyzed fatty acids and stable isotopes from blubber and skin samples of five different humpback whale populations around the southern hemisphere.

These levels were then compared with those of their primary prey item, Antarctic krill.

The team found that although there were distinct differences in the biochemical profiles, the diet of all tested humpback whale populations was Antarctic krill, which provides a high fat content diet ideal for the migratory lifestyle of these populations, Dr Groß said.
