~~~ Hawaii Weather Narrative ~~~



Light winds through mid-week, then light trades into Friday…followed by light southeast breezes along with more vog again by the weekend. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean. We find a high pressure systems west of the islands and east-northeast of the state…with an associated ridge of high pressure over Hawaii. In addition, there’s deep storm low pressure systems far to the north and north-northeast of Hawaii. The storm to the north has an associated cold front, which will be moving by not far to our north. The chilly and dry  breezes of the last couple of days, which arrived in the wake of this past weekend’s cold front, will continue into Wednesday, although become lighter and variable in direction, with periods of vog locally. The forecast then shows light trade winds during the second half of this work week. As we get into the weekend, a cold front will approach the state, swinging our winds around to the southeast…with returning volcanic haze over many areas of the state.

Here’s a wind profile…of the offshore waters around the islands – with a closer view

Here’s the Hawaiian Islands Sulfate Aerosol…animated graphicshowing vog forecast

A relatively cool and very dry air mass remains over the state…with very limited showers if any. Dry air continues to come into the state in the wake of this past weekend’s cold front, so showers are very limited everywhere. Rainfall should remain limited during the first half of this week. This is due to the very dry and stable atmosphere that is parked over the Hawaiian Islands at this time. We have light winds currently, with daytime onshore flowing sea breezes, and in combination with the daytime heating of the islands…will prompt afternoon clouds to form over the interior sections. As the trade winds return during the second half of the work week, a cold front moving by to our north may contribute a few showers along our windward sides. The next best chance of a cold front arriving into the state would be late Sunday into next Monday, which could bring showers and stronger winds our way then – stay tuned.

Here in Maui CountyIt’s mostly clear, with a few low clouds along the windward sides early this Tuesday morning. Here in upcountry Kula we have an air temperature of 41.9F degrees before sunrise. The temperature at near the same time was 55 degrees down in Kahului, 57 out in Hana, 54 at Maalaea Bay…and 43 atop the Haleakala Crater. Meanwhile, Kahoolawe was 59 degrees, 60 at Lanai City, with 57 at the Molokai airport.

It’s very early afternoon, with a cool breeze blowing here in Kula, under really nice and warm sunshine! There’s that same haze today that was around yesterday afternoon too. It’s a bit thicker today than on Monday, and has become rather thick later in the day. / Late afternoon, clouds have formed over and around the mountains, leaving the beaches mostly sunny and clear…although hazy. The air temperature here in upcountry Kula at 425pm was 68.7 degrees…coming down after reaching a high temperature of 71 degrees.

Early evening, under clear to partly cloudy skies, although the clouds over and around the mountains will evaporate soon after sunset. The volcanic haze is thick, and will remain in place through Wednesday I’m afraid, at least on some of the islands…certainly here in Maui County. As the clouds clear, and we have downslope flowing air coming off the mountains towards the ocean, our temperatures will plummet again tonight, bringing yet another cold morning Tuesday. Keep that extra blanket on your bed, and perhaps put on those socks again tonight. The air temperature here at my Kula weather tower, before sunset is 64.9 degrees. / 620pm has 61.8 here in Kula / 805pm has 53.7 here in Kula…while near the same time, it was 71 degrees down in Kahului / 815pm 52.3 – by the way, the reason it’s warmer tonight than last night, and the temperature is falling slower, is that we still have clouds hanging around, which holds the heat in, and keeps the temperature from falling as fast as it would…if it were clear / 825pm 51.5 degrees

I’ll be back with many more updates on all of the above and below, I hope you have a great Tuesday night wherever you’re spending it! Aloha for now…Glenn

Interesting: 
Over 50 Percent of the World Breathes in Toxic Air
– Everyone needs clean air to survive, yet somehow it is not an internationally recognized human right. That probably has something to do with the fact that over half of the world’s population live in areas where they breathe in toxic air. Altogether, that means there are more than 3.5 billion people inhaling dangerous air into their lungs on a daily basis.

A lot of present day discussions about pollution focus on the long-term consequences that are in store thanks to climate change. While those discussions are certainly important, the truth is that we don’t need to make predictions about future environmental catastrophe to see the harms of pollution – those harms are already here.

The Environmental Protection Index (EPI) track changes – both improvements and regressions – on a number of important environmental issues. Air that is unsafe to breathe is one area where researchers see conditions getting alarmingly worse.

Air should be life giving, but for half the world, that’s no longer the case. Currently, health officials attribute about 5.5 million deaths around the world to unclean air each year. Given that over 50 million people die in a given year, toxic air deaths account for roughly 10 percent of all deaths.

In better news, the EPI is simultaneously reporting a major decrease in consumption of polluted water. In 2000, about 1 billion people drank unsafe water, a figure that has essentially been cut in half in the past fifteen years. Access to clean water is expanding because poorer nations are industrializing and technologies are improving.

Alas, it’s hard to argue that this industrialization is a net positive for the environment. While providing clean water to hundreds of millions of people who lacked it previously is an unquestionable benefit, industrialization is also a huge reason for the rise in air pollution.

Accordingly, it’s heavily populated countries like China and India that are rapidly expanding their number of factories and businesses that are most threatened by air pollution. For example, in India and Nepal, this gross air is almost inescapable: 75 percent of the overall population in this region is regularly exposed to deadly smog.

“With the very survival of the planet at stake, we hope leaders will be inspired to act – especially in urban areas where an increasing majority of the world’s population lives,” said Kim Samuel, one of the lead researchers on the EPI report.

The health of the economy is important – but it shouldn’t come at the cost of the health of humanity. Exposing half the world to unsafe air sounds like nothing short of a catastrophe, yet it’s a choice global leaders are implicitly making by agreeing to only insignificant changes in environmental policy.
