~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Thursday comments:  I’m home here in upper Kula, Maui, I hope you have a great Thursday wherever you happen to be spending it.

558am, clear early this morning…the low temperature here at my Kula weather tower was 55.5 degrees. The big October super full moon is dominating our early morning skies, as it sinks slowing into the western horizon.

1003am, yet another day of almost completely clear skies here in Maui County.

1201pm, I was up the mountain skateboarding again this morning. There was less traffic than usual for some reason, which meant that I had less pulling over to let a car go by. It was totally clear when I got up there, although by the time I left, it had clouded over.

902pm, partly cloudy with the still full moon brightly shining. My high temperature today was 78.5 degrees.

MINOR COASTAL FLOODING DURING HIGH TIDE THROUGH SUNDAY… Peak monthly high tides will bring minor flooding along the shoreline and in low-lying coastal areas. Coastal flooding is possible around the daily peak tide which will occur during the early morning hours.

Outlook for the wet season (October 2024 through April 2025) – Hawaii

– NOAA’s Climate Prediction Center (CPC): La Niña is favored to emerge by the
end of November and is expected to persist until spring 2025.
– After a slow start to the wet season, the climate model consensus favors large
scale above average rainfall from December 2024 through April 2025.
– Rainfall distribution can be influenced by the strength of La Niña.
– Stronger La Niña events can have a higher than normal trade wind
frequency which can focus rainfall on the east-facing windward
slopes.
– Weaker La Niña events can have more weather systems that
produce significant leeward rainfall.
– Probabilities favor a weak La Niña event.
– Drought across the state should be eliminated by the end of the wet season.
– Other impacts
– Probabilities favor above normal temperatures for the state.

 

Hawaii’s Broad Brush Weather Overview:  An area of moisture will bring an increase of showers today, especially over windward and mountain areas. Moderate to locally breezy east to east-southeast trades will gradually decrease through Friday, then restrengthen this weekend out of our typical east-northeast direction. A mostly dry and breezy trade wind pattern is expected for the weekend, with some scattered light showers possible.

Hawaii’s Weather Details:  Satellite imagery shows an increase of clouds and showers over windward Big Island and east Maui. Atmospheric sounding from Hilo shows a quite a bit of change in the moisture profile compared to yesterday where we had 1.04 inches of precipitable water vs 1.78 inches today.

With this increase of moisture, we should see fairly showery conditions over windward Big Island and east Maui today, with scattered showers increasing over the rest of the state. Some ponding of water on roadways will be possible, especially during the afternoon as the rainfall intensities slightly increase. This increase of moisture will be short-lived, with drier conditions returning by this weekend.

As far as winds, a high far northeast of the state will maintain moderate to locally breezy trade winds across the state today. A cold front northwest of the state, will cause the trade winds to be out of the easterly direction, and even a touch south of due east through Friday.

With this wind direction, a few leeward areas could be sheltered from our typical east-northeast trades with some localized sea breezes possible today and especially on Friday, when the trades weaken a little more. Breezy east- northeast trades will return by Saturday afternoon, and should remain breezy through the weekend.

For next week, a trough developing northwest of the state should cause the trade winds to gradually weaken Monday into Tuesday. There are still uncertainties on how weak the trade winds will get. Some periods of increased moisture should be expected at times, although the areas where these showers will occur will depend on the wind speeds and directions.

Hawaii’s Marine Environment:  Fresh to strong easterly trades will gradually ease through Friday, as a weakness forms in the ridge to the north. While light and variable winds may develop over the Oahu and Kauai waters later tonight into Friday, fresh to strong trades will persist over the eastern end of the state.

As a result, the Small Craft Advisory has been extended over the windier waters and channels around Maui County and the Big Island. Fresh to locally strong easterly trades will return over the weekend, then weaken again early next week as broad gales form far northwest and northeast of the state.

Surf along north-facing shores will steadily fade through the second half of the week, as a north-northwest swell moves out. A small pulse is possible over the weekend and into early next week, which should be enough to prevent the surf from going flat. An upward trend is possible late next week, due to the aforementioned gale forming northeast of the state Monday through mid-week.

Surf along south-facing shores will remain small, with mainly a mix of south-southeast and south-southwest swells moving through. The next small southwest swell is expected over the weekend, with a similar pulse arriving early next week.

Surf along east-facing shores will remain small and choppy each day through the weekend, then trend down as the trades ease locally and upstream early next week.

Peak monthly tides could lead to minor coastal flooding in the typical low-lying vulnerable areas around or just before daybreak each day through the weekend, beginning Friday morning.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

 >>> East of the Leeward Islands:

Invest 94L

A poorly-defined trough of low pressure is producing disorganized showers and thunderstorms extending from the northern Leeward Islands northward for a couple hundred miles over the adjacent Atlantic waters. Development, if any, of this disturbance should be slow to occur while it moves quickly westward to west-northwestward at around 20 mph, passing near or just north of the Virgin Islands and Puerto Rico today, then near Hispaniola and the southeastern Bahamas on Saturday. By late this weekend, further development is not expected due to strong upper-level winds.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…low…10 percent

Caribbean Sea:  There are no active tropical cyclones

 >>> Western Caribbean Sea:

Invest 95L

Widespread showers and thunderstorms continue across the northwestern Caribbean Sea in association with a broad area of low pressure that is gradually becoming better defined to the north of eastern Honduras. Environmental conditions appear conducive for some additional development over the next day or two, and a short-lived tropical depression or storm could form before the system moves inland over Belize and the Yucatan Peninsula of Mexico on Saturday. Regardless of development, locally heavy rainfall is likely across portions of Central America and southern Mexico through the weekend.

* Formation chance through 48 hours…medium…50 percent
* Formation chance through 7 days…medium…50 percent

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific:  There are no active tropical cyclones

>>> South of Southwestern Mexico:

An area of low pressure is expected to form by the middle part of next week well offshore of southwestern Mexico. Gradual development is possible thereafter, and a tropical depression could form during the middle to latter portion of next week as the system moves westward at 10 to 15 mph.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…40 percent

Interesting:  Intense, Widespread Drought Grips South America

Rivers in the Amazon basin fell to record-low levels in October 2024 as drought gripped vast areas of South America. Months of diminished rains have amplified fires, parched crops, disrupted transportation networks, and interrupted hydroelectric power generation in parts of Brazil, Bolivia, Colombia, Ecuador, Peru, and Venezuela.

This pair of Landsat images illustrates the shrinking Solimões River near Tabatinga, a Brazilian city in western Amazonas near the border with Peru and Colombia.

On October 4, 2024, river gauge data from the Brazilian Geologic Service indicated that the Solimões had fallen to 254 centimeters below the gauge’s zero mark, a record low. Rivers that day also reached record lows near the cities of Porto Vehlo, Jirau-Justante, Fonte Boa, Itapéua, Manacapuru, Rio Acre, Beruri, and Humaitá. Water height data collected by satellite altimeters and processed by a team of NASA scientists reported unusually low water levels at several Brazilian lakes and reservoirs as well, including Lake Tefe, Lake Mamia, Lake Mamori, Lake Ariau, Lake Faro, and Lake Erepecu.
