We can use the following links to see what’s going on in our area of the north central Pacific Ocean. Here’s the latest NOAA satellite picture – the latest looping satellite image… and finally the latest looping radar image for the Hawaiian Islands.

~~~ Hawaii Weather Narrative ~~~

Our winds will be generally light to moderately strong for the time being. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean. Here’s a real-time wind profile of the central Pacific…centered on the Hawaiian Islands. ~~~ We find low pressure systems to the north-northwest of the islands, with the tail-end of a cold front stalled over the state. There’s yet another cold front/trough approaching from the northwest as well. At the same time, we see now high pressure systems well northeast of the islands. It appears that we’ll get back into a trade wind flow Friday…into the weekend, followed by lighter southeast winds ahead of another cold front Sunday into early next week.

Satellite imagery shows rain clouds, straddling Oahu for the most part…with far fewer showers elsewhere in the state.
Those brighter white clouds are causing cloudy to partly cloudy conditions at the time of this writing. There are one or two towering cumulus over the waters around Oahu, and to the north of Maui County. Here’s the looping radar image, showing showers coming into the state for the most part over Oahu. Most of these are light to moderately heavy showers. Looking at this larger satellite image, which is in the looping mode, we can see clouds being pulled northeastward across our area, most of these are of the high and middle level variety, although with rainy clouds in the mix in places too.

There’s still an active band of showers over the central islands, which will be pulling westward towards Kauai. Wednesday may show some good improvement over the eastern islands, although showers will remain at least somewhat active over the western part of the state. However, as we get into Wednesday night into Thursday, rains could turn more generous again over Kauai and Oahu. Then, as we push into Friday and the weekend, the trade winds are forecast to return briefly, with windward showers. The computer models continue to suggest that another cold front will migrate by just to our north early next week, prompting lighter winds from the southeast Sunday for a day or two. I’ll be back early Wednesday morning with your next new weather narrative, I hope you have a great Tuesday night wherever you’re spending it! Aloha for now…Glenn.

Here on Maui early this morning, at the 3,100 foot elevation, at my upper Kula, Maui weather tower, the outdoor air temperature sensor was reading 58.6F degrees at 555am this morning. It was partly cloudy, although there was no rain falling at the moment. Once it gets light, I’ll be able to have a better look around.

~~~ Cloudy, cloudy, cloudy…although there are a few blue patches around the edges. It’s mostly middle level clouds, with not many lower clouds…and it was dry as I write these words. The air temperature at 805am was 59.4 degrees, and it was calm. I have to go down to Wailuku town now, but will be back with more updates a little later this morning.

~~~ I’m back from downtown, and our weather conditions are looking much better, at least in terms of our wet weather for the moment. The island of Oahu and part of Molokai are still under the gun in terms of rainfall, and it may eventually shift eastward over more of Maui County. The clouds over Maui are generally the middle level clouds, leaving the top of both the West Maui Mountains, and the Haleakala Crater…both under these clouds. The air temperature here at my Kula weather tower was 68 degrees at 1045am.

~~~ It’s now early in the afternoon, with still lots of clouds over head. There were actually a few brief sunny spells earlier today, which is a bit unusual lately. The clouds are beginning to lower now, as I can see some fog not far up the mountain from here. The majority of the clouds however, continue to be the middle and high level variety. Radar continues to show that most of the rainfall is falling over Oahu, and the ocean to the northeast through southwest. It seems to be trying to edge down over Molokai, although Maui County is much drier than it was yesterday. The air temperature at the moment, at 1230pm, was 70.2 degrees, with light winds blowing.

~~~ This afternoon the clouds forming along the Haleakala Crater slopes gathered force, and finally let loose with a few light showers. At the moment here in Kula, at 605pm, it’s foggy, with just a light mist…and an air temperature of 65.5 degrees. I expect these clouds to evaporate quite a bit after dark, with a better day weatherwise here on Maui, and likely on the Big Island too. The daytime heating of these larger islands will likely generate more of the afternoon clouds however, with the chance of a few more showers Wednesday afternoon. The persistent band of showery clouds, that hung over Oahu, is expected to migrate westward over towards Kauai during the next 12-24 hours.

Interesting: Building Green –
In a world which faces increasing pressure to reduce carbon emissions, the construction industry must confront demand to adopt modern methods of building which causes less damage to the environment. As a result, there are increasing numbers of alternative materials and methods available, a selection of which are included in this post. While these methods are by no means the only ones available within the industry, the selected materials and methods include:

-Metallic paint

-Chemical containment

-Spray-on insulation

-Concrete alternatives

-Green roofs

Each method boasts the more efficient properties in terms of reducing environmental damage, with the least change to standard methods.

Metallic paint

Until relatively recently, metallic paint has largely been used in agricultural and industrial structures, to protect corrugated sheeting from weakening in exposed sunlight. However, this simple addition has been recognized as a cost-effective method of increasing the lifespan of building materials.

Chemical containment

There is no end to the amount of damaging chemicals present on a construction site, whether that’s bitumen, varnish or even paint. When you’re dealing with chemicals that could cause damage to the environment, especially in large quantities, it’s important to take measures to contain these substances as much as possible.

An eco spill pallet, available from industrial suppliers, is a relatively simple and affordable piece of equipment for a building site, which could have a big impact on your efforts to be more environmentally friendly. Use it to store chemicals and drums, and contain leakages and spills with little fuss.

Spray-on insulation

Insulation is a vital part of any build that strives to be as efficient and as green as possible. While traditional materials like fiber roll insulation boast effective thermal properties, newer and more innovative techniques such as spray on insulation offer even more benefits and efficient insulation. Walltite is one such example, which utilizes a spray on application to create an airtight layer design for internal walls, floors and roofs.

Concrete alternatives

Recycled building materials are becoming much more common place, as construction firms strive to be environmentally friendly.

Concrete production accounts for around 5% of all carbon emissions, so this is a key area of focus for cutting emissions in the industry. Alternatives such as honeycomb blocks are increasingly common, especially in continental Europe, and boast lightweight, insulating designs, without the associated carbon output.
