~~~ Hawaii Weather Narrative ~~~
Our winds are coming in from the southwest through southeast…keeping muggy weather over us into Friday. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a wind profiler of the central Pacific. We find a large, moderately strong high pressure system far to the north-northeast of the state. At the same time we see Tropical cyclones far to our west, closer to our north-northwest, and further to the east…and finally offshore from Mexico. Our winds continue to come to us from the uncommon southerly direction, keeping sultry conditions in place. We should see the return of light trade winds later Friday into the weekend, which will give a slight relief from the hot and humid conditions. As we move into early next week, we will see the trade winds faltering again, as Jimena’s presence over the ocean to the northeast interrupts the wind flow then. This in turn will bring back very muggy conditions for many days.
Spotty heavy showers will continue Friday…along with a possible thunderstorm to. As Ignacio continues to move further away, we’ll see showers continuing, as tropical moisture lingers in our island vicinity. As the winds remain quite light during this time, we will see heavy downpours over the interior sections of the islands during the afternoon and early evening hours…triggered by daytime heating of the islands. Showers will likely form over the warm ocean during the night and early mornings too, and spread onto the islands locally. This unsettled weather pattern will persist into the weekend. As the light trade winds try and get going later Friday into the weekend, we may see the return of a few windward showers…although with still those afternoon downpours locally. As the trades falter again early next week, thanks to hurricane Jimena, we’ll get right back into a convective weather pattern, with locally heavy afternoon showers in the upcountry areas.
Tropical Storm 12E (Ignacio) continues to move away from Hawaii…posing no threat. Here’s a satellite image, and the CPHC graphical track map, and what the computer models are showing. Based on the most recent advisory, Ignacio has 70 mph winds near the center, and has dropped down from its brief return to the hurricane level. The forecast has this storm remaining at about 75 mph for the next 12 hours or so. As it migrates further north, it will pass over the progressively colder waters of the north Pacific Ocean…and become a post-tropical cyclone within two days.
Incoming east swell from hurricane Jimena continued to require a high surf warning for east-facing shores of most islands. East-shore surf will remain near warning levels through the weekend, and likely into early next week.
A small craft advisory also remained in effect through this afternoon for hazardous seas produced by the swells from Ignacio and Jimena. Winds are expected to remain below the advisory threshold this week.
Meanwhile, Hurricane 13E (Jimena) remains active well to our east. This hurricane is maintaining sustained winds of near 85 mph as of the latest advisory. Here’s a satellite image, and the CPHC graphical track map, and what the computer models are showing. This is still a strong hurricane, although will be gradually losing power as it heads northwestward. There continues to be a chance that hurricane Jemina will stay away from our area, well to the east, northeast and then north of the state later this weekend into next week. Looking at the latest track map, it looks like this tropical cyclone will take a turn westward…and hopefully remain well away from our islands
Here on Maui…It’s 555am Thursday morning, and it’s mostly clear towards the west, and partly to mostly cloudy to the east. The clouds to our east, have flickering lightning this morning, lots of it. However, at least from here in Kula, I can only hear a very faint thunder far in the distance…once in a while. There is a flood advisory over on the windward side of east Maui, so we know it’s getting very wet out near Hana, Nahiku, and Kipahulu. In addition, there’s a flash flood watch for the entire state today, which suggests that the atmosphere is very unstable and moist…and of course shower prone with thunderstorms here and there. / At 605am, around sunrise, the anvil top of a huge thunderstorm offshore to the south, lit up an incredible pink color! / I just got back from my fast walk, and while I was out there, I was amazed at how many towering cumulus clouds, and thunderstorms there are in our skies this morning! I’ve live here in the islands for 40 years, and this is one of the most spectacular days that I can remember for thunderstorm displays…they’re in almost every direction. This will be an usual day, especially as the daytime heating of the island kicks in, which is happening now, very likely triggering some heavy duty, flooding downpours in some areas. Already there is some big flooding issues over on the windward side of east Maui at the moment. / A little while later, and those early morning puffers have diminished some, although there are still lots of them mostly centered to the north, northeast and east. / Now at 1015am the flood advisory for Maui has been discontinued, looking around, the thunderstorm activity has rather quickly dissipated, although I can still see one or two around the edges. We’ll see what happens this afternoon, as the sunshine continues to bake the island. / Just like bread rises when baked, the air rises when heated from below, as well as sea breezes begin to swagger up hill, all of which prompts clouds to grow taller…and raindrops to fall from their moisture laden bellies…time will tell. / At 1110am, glancing down the mountain from here in Kula, it’s looking like moderately thick volcanic haze (vog) has returned…it’s good an voggy all the sudden.
– Alright here we go into the early afternoon period, under totally cloudy skies. I can’t see out anymore, as the clouds have closed in over me here in Kula. At the same time, we just had our first brief shower of the day, one of those big drops kind that don’t last long, followed by thick fog! Why an exclamation mark? I’m not sure, it just snuck by my good reasoning…my only excuse is that I get excited by the weather I suppose. Oh, did I mention that I’m hearing thunder, closer now, which of course means there’s lightning around too.
– We’re into the early evening hours now, and I can’t see down the mountain here in Kula…as its cloudy and foggy too. There have been several little showers today, although there was no downpour, like we’ve seen up here over the past several afternoons. The air temperature is right around 70 degrees at 535pm, which is more comfortable than it has been lately. At about the same time, down at the Kahului airport, it was 83 degrees. The fog just cleared up slightly, enough so that I can see what looks like pretty thick volcanic haze (vog) in our skies.
I’ll be back with many more updates on all of the above and below, I hope you have a great Thursday night wherever you’re spending it! Aloha for now…Glenn.

Interesting: Climate Change will Cost Trillions – The economic ramifications of continuing the 20th century’s economic model, where unsustainable extraction and pollution conveys competitive advantage, are coming into sharp focus. Citigroup now projects a staggering $72 trillion global cost tied to man-made climate change during the 21st century. This is an almost incomprehensible scale of economic damage that is equal to losing four years of the United States’ entire gross domestic product.
The agriculture and food manufacturing industries also confront similar staggering economic consequences. The industrial fast food complex is directly tied to a global obesity and diabetes epidemic that now costs $2 trillion annually, or almost 3 percent of world gross domestic product. If this cost remains constant it will represent $170 trillion in economic cost through the rest of the 21st century.
These staggering economic costs don’t even take into account human suffering and premature death. A telling example is that 4,000 people per day, or 1.6 million per year, are estimated to die prematurely in China due to air pollution. This is a morbidity population that is 33 percent larger than the entire population of San Diego. In terms of the morbidity rate tied to our food system, in the U.S. alone over 75,000 people die each year due to diabetes.
Consumers, markets, politics and sustainable economics
The scale of the numbers tied to unsustainable human and environmental impacts are now too large to be wrong or ignored. Continued purchases of fossil fuels in the quantities now being consumed is an exceedingly poor economic decision. Health research now documents that sugary drinks are the 21st century’s tobacco, in terms of negative human health and cost consequences. The question is why consumers and the political system are comparatively unresponsive to numbers that can only be described as staggering.
The answer is based on the distinction between traditional economics and behavioral economics. Traditional economics is based on the concept of rational consumers and markets. It assumes that people will not borrow more than they can pay back and that lenders will not optimize short-term profits by aggressively promoting high risk, highly leveraged loans. Based on these assumptions, traditional economics would not forecast the 2007-2008 Great Recession. But it did happen because people and markets are not rational. The study of behavioral economics is based on the assumption that people and markets make decisions that reward themselves in the short term by ignoring or grossly underestimating long-term consequences until they become too large to ignore any longer.
The irrational consumer, market and voter now define our economy. For example, it is political suicide to propose raising pump prices to discourage the scale of fossil fuel consumption that is projected to create $72 trillion of climate change costs. Raising gasoline prices was also political suicide in 1974 when it was proposed as a solution to an OPEC oil embargo and continued entanglement in Middle Eastern wars. Imagine our national history if we had the economic will to accept higher pump prices as a cost alternative to Middle Eastern wars and pollution.
Another example is the attempt to regulate sugary drink consumption through public policy, taxes or both. Politically, such actions garner consumer and political responses that appear tantamount to a “live free or die” defense of the U.S. Constitution. But public policy designed to limit consumption of sugary drinks to reduce obesity levels is proving to work in Mexico, where a 10 percent tax on soda generated a 6 percent drop in first-year consumption. The economics appear compelling. Taxing sugary drinks will reduce consumption, and reduced consumption is the solution to reducing the staggering cost of obesity and diabetes. Fundamentally the consumer and political issue is not knowing what to do but rather having the consumer and political will to act on behalf of our economic, human health and environmental long-term interests.
The implications of adopting sustainable economics
The sobering reality is that issues like removing lead from gasoline, mandating automobile seat belts and limiting tobacco sales have historically taken approximately 50 years to move from initial activism for change to the adoption of change. Applying this same time-scale to the issues of climate change and obesity would create staggering losses in human health and economics.
We are now at a decision-making crossroads. The study of behavioral economics recognizes that consumers, politicians and businesses will make decisions resulting in substantial economic loss and human health costs based on a bias toward maintaining the status quo. It recognizes that consumers and voters will make decisions that reject science and statistics to protect strongly held beliefs. People and businesses will delay or procrastinate in taking actions that will advance their long-term welfare because change can be hard or discomforting. These behavioral economics factors are now threatening to generate staggering economic and human suffering damage.
In economics there is no such thing as a free lunch, and the pain from not adopting sustainability will eventually be overwhelming. This level of pain will generate mega-shifts in stock valuations, a restructuring of market share away from companies that gain competitive advantage through pollution, and the emergence of new companies that win customers by delivering price competitive and sustainable solutions.

Hi Glen,
I have enjoyed your weather info for so long that I am not sure when you first caught my eyes. Maybe it was in relation to the Maui News Paper. I live in Pukalani and did not think that ac in my home would ever be needed.
In the latest interesting global climate change will cost trillions I was wondering if you are the author. If so I
just want to second the motion that is high time to take reins and direct the horse to a healthier pasture.
Where do you find all these interesting subjects?
Anyway I enjoy your work! Please keep it up!
My dog is panting in Pukalani.
Mahalo Martin
~~~ Hi Martin, good to hear of you, and yes, you’ve been a long time follower of my weather information…I’m glad you’ve found value after all these many years.
No I’m not the author of the recent Interesting Article, it was Bill Roth. I find interesting pieces, and am never the author, I just pass along on my website as a, well…just interesting articles.
Your dog is panting in Pukalani, and by the way, thanks for letting me/us know where you are writing from. It’s been hot, I’m already looking forward to the autumn season, perhaps that will bring some relief, and of course winter is my favorite season here in the islands…that’s the perfect weather for me.
Thanks for writing in Martin, I appreciate it…take care my friend! Aloha, Glenn
Emily Says:
Hi Glenn,
Thank you for such a descriptive and comprehensive site! Like Andrew above, I’m visiting Maui 9/5 – 9/13, and have been using your site to monitor the weather and hurricanes! Very useful.
Like Andrew, I’m apprehensive about the hurricane. It also seems like we’re going to be facing some pretty heavy rain and pretty intense humidity next week, correct? Do you think we should reschedule our trip?
Thanks,
Emily
~~~ Hi Emily, I’m not sure where you’re writing from, it’s always nice to know.
Yours is a very valid question of course…considering that you’re coming into a period that isn’t normal. You know, the only wild card that I see is what Jimena will do. It looks likely to keep us muggy, which means afternoon showers…although those will mostly be over and around the mountains during the afternoons.
Whether Jimena will come close enough to influence our weather otherwise, that’s the question now. The way the forecast track is turning a little more towards Hawaii, of course puts folks back on edge. We just got OFF EDGE as Ignacio went by, so everyone’s nerves are a little crispy still.
Let’s hope for the best, and I’d strongly suggest paying attention for the next few days, and see what the forecast track map shows.
Best of Luck, Aloha…Glenn
Maggie Says:
Hi Glenn! There was an old sci-fi TV series in 1967 called “The Invaders”. It stared Roy Thinnes and was about alien doppelgangers trying to take over the planet. In one classic episode, the aliens hid a machine in a small florida church that churned up an abnormal number of hurricanes. The latest satellite photos on your web site certainly remind me of the visuals from that old TV show.
I’ve spent considerable time in Singapore and Bangkok and our recent weather has been much closer to theirs than anything I’m used to here – especially the fast forming tropical thunderstorms. It will be interesting to see how El Nino affects winter weather here in soggy Haiku.
As always, many thanks for keeping us all informed!!!
~~~ Hi Maggie, good to hear from you over there on the windward sides. Windward, or at least it used to be…smiling! I know, it’s so unlike Hawaii, so unlike what we’re used to, really different! Thunderstorms, stagnant air, vog in the summer, hurricanes whizzing by each week, hmmm, the the heck!
El Nino here in the winter, I somehow doubt whether you will be soggy, you might be praying for rain about then…that’s the problem, with these more extreme times we seem to be entering.
I’m delighted to keep you brief-up on the weather, it is my pleasure, there’s so much to talk/write about these days…thank you for visiting my site!
Aloha, Glenn
Andrew Says:
Aloha Glenn,
Inquiring from California. Thank for the information for next week. I guess we can find a silver lining in any scenario, looking forward to shedding a few LB’s in the heat and humidity.Thank you for your service.
Andrew
~~~ Hi Andrew, that’s a good way of thinking about it, shed a few extra ones! You are very welcome by the way, and let’s hope you’re here when the trade winds start to blow again, bringing at least a little relief from the sultry conditions. It’s interesting, when I think about my most un-favorite weather conditions, hot and muggy comes to mind immediately!
Have a great vacation here in Paradise, and thanks for having a positive outlook…that’s a cool thing to have in this day and age.
BTW, thanks for letting me/us know you are writing from California!
Aloha, Glenn
Doug Says:
Aloha Glenn,
So is it a correct assumption that the tail end of the counter-clockwise spin of Ignacio is now dragging moisture out of the South up over us or is it something else entirely?
Doug
~~~ Hi Doug, that’s is precisely what’s happening! I was just making my lunch, and I was thinking to myself, I might as well live in Jamaica, or Cuba, or Miami, or someplace that doesn’t have regular trade winds. It’s just amazing to be without the refreshing trade winds for so long. Essentially, the trade winds are what gives Hawaii the outstanding weather that we have, and I’m not going to say, that we used to have…as they will return. Once they come back, it will feel normal again. The only problem is that the ocean surrounding the islands is warmer than normal, so that whatever winds blow over the warm ocean, will bring that warm and moist air over us. It’s just incredible, and i recently read on a NWS site, that the forecaster was calling it insanely humid…and he was talking about here in Hawaii!
Aloha, Glenn
