~~~ Hawaii Weather Narrative ~~~

 

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

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

6am, it’s mostly clear early this morning here in Kula, with a chilly low temperature of 52.5 degrees at my place.

904am, the clear skies earlier this morning have become partly cloudy…with the beaches remaining the most sunny at this point.

211pm, the partly cloudy skies prevail, along with some sunny and cloudy areas around Maui County this afternoon.

10pm, the afternoon clouds have cleared well, with all kinds of twinkling stars in their place. My high temperature here in upper Kula was comfortable 79 degrees.

 

Hawaii’s Broad Brush Weather Overview:  A stable moderate trade wind pattern with mainly light windward showers will prevail through Monday. Increasing trade winds and slightly wetter conditions are possible during the middle of next week, with breezy trades continuing into the weekend.

Hawaii’s Weather Details:  The latest models and radar imagery show less in the way of showers through the rest of this weekend. In addition, the 12Z soundings from Hilo and Lihue show increasing stability across the state with inversion heights around 4,500-5,500 feet, about 1,000 feet lower than Friday at this time.

A surface ridge far north of the islands will maintain the current trade wind regime through the upcoming week. A developing surface high far northeast of the state will strengthen the local pressure gradient over the islands by the middle of next week, resulting in an increase to breezy trade wind speeds.

A mid- to upper-level ridge over the islands will maintain the relatively dry and stable conditions through this weekend. Any showers that do reach the islands should only produce modest rainfall amounts and are expected to be focused over the windward slopes, with a few showers possible over the leeward slopes of the Big Island each afternoon.

The GFS and ECMWF models continue to show an increase in precipitable water reaching the islands Tuesday or so, although the focus has shifted a bit towards the southern end of the state. Expect a few more showers over the windward sides of the smaller islands, and a bit more of an increase over windward Big Island. The increase in trade wind speeds during that time will allow some of those showers to reach some leeward areas at times.

Hawaii’s Marine Environment:  Gentle to locally fresh trades continue, then become locally strong during the first half of next week. This will likely warrant a Small Craft Advisory for the typically windy waters around Maui County and the Big Island.

Surf remains small along all shorelines through the forecast period. Mixed swell out of the southerly quadrant will maintain small surf along south-facing shores, maintaining slightly perturbed conditions through much of next week.

Likewise, small surf persists for northern exposures, although mixed swells out of the northerly quadrant may provide a small rise for the weekend.

A northeast swell will maintain small surf along east-facing shores, even as background trade wind swell subsides. Choppy conditions then return as trades strengthen next week.

The combination of higher than normal water levels and afternoon spring tides are resulting in water levels running over half a foot above guidance around the Big Island and Maui. This will cause minor coastal flooding issues for both Big Island and Maui, mainly during afternoon peak high tide. Coastal Flood Conditions are borderline around Maui and the Coastal Flood Statement may be dropped there sooner than the Big Island.

World-wide Tropical Cyclone Activity

 

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:  There are no active tropical cyclones

Gulf of Mexico:  

Tropical Cyclone 02L (Beryl) is located about 275 miles southeast of Corpus Christi, Texas…according to the NHC advisory number 34A

BERYL FORECAST TO BECOME A HURRICANE AGAIN BEFORE LANDFALL…HURRICANE AND STORM SURGE WARNINGS REMAIN IN EFFECT FOR PORTIONS OF THE TEXAS COAST

Beryl is moving toward the northwest near 13 mph and this motion should continue through today. A turn toward the north-northwest is expected tonight, with a turn toward the north on Monday. On the forecast track, the center of Beryl is expected to make landfall on the Texas coast Monday morning.

Maximum sustained winds remain near 60 mph with higher gusts. Strengthening is expected, and Beryl is forecast to become a hurricane again later today or tonight before it reaches the Texas coast.

Tropical-storm-force winds extend outward up to 125 miles from the center. NOAA buoy 42002 in the western Gulf of Mexico recently reported a sustained wind of 36 mph and a gust of 47 mph.

Interesting:  How much will climate change drag down the economy?

Cartoon of people looking at a chart on a projection screen. The caption reads, "We ran the numbers on how climate change will affect economic growth, but the numbers got so spooked they just kept running."

Category 5 Hurricane Otis roared through Acapulco, Mexico, in October 2023, the city was left in ruins.* Winds stripped facades from beachfront buildings and storm surge flooded lobbies. The storm killed at least 50 people and damaged 80% of hotels in the once-glittering resort town. Six months later, a Bloomberg reporter described “a grim scene,” with many buildings left abandoned and “swimming pools full of muck.”

And residents were still working to bring tourists back.

“If there’s no tourism, nothing happens,” Juan Carlos Díaz, a 59-year-old laborer, told an AP reporter. “It’s like a little chain, it generates (money) for everyone.”

As the climate warms and the weather grows more extreme, similar events could unfold in places worldwide, with the potential to devastate — or at least drag — the economy. Economists agree that climate change will cause severe damages and costs, but teasing out exactly how and how much it’s likely to affect the world’s economic engines is a matter of fierce debate in the academic literature. For example, will an extreme weather event impose one-time costs from which governments can quickly rebound, or will it create a persistent drag on the economy? About three-quarters of climate economists think the latter scenario is likely.

The debate is crucial because the costs of slowed economic growth compound over time. For a large economy like that of the United States or the world, just slightly stunting economic growth can add up to tens or even hundreds of trillions of dollars in lost wealth by the end of the century — making climate solutions look like an absolute bargain.

An April 2024 study in the journal Nature led by Potsdam Institute climate economist Maximilian Kotz estimated that climate damage costs by 2050 will be six times larger than the cost of reducing carbon pollution consistent with world’s targets under the Paris climate agreement over the same time frame.

And climate economists risk underestimating the potential price of inaction because they can only account for the costs of extreme weather events and impacts for which data are available.

“Climate damages are always going to be underestimated,” said Columbia climate economist Gernot Wagner in a phone interview. “Some things we just can’t quantify. For most of those uncertain climate damages, we have precisely and incorrectly estimated their cost at zero.”
