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 ~~~
Northeast winds are now active, with moderately strong breezes continuing through this week…locally a bit stronger at times. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profile of the central Pacific…focused on the Hawaiian Islands. ~~~ We see moderately strong high pressure systems far to the northeast and northwest of our islands. They have ridges of high pressure located offshore to the north and east of the state. At the same time, we see a gale low pressure system to our north-northeast, with an associated frontal boundary breaking through this ridge…located just offshore to the south and east of the Big Island at the time of this writing. Our local winds will remain active through Wednesday, then slip a notch Thursday and Friday, as a cold front moves by to our north. As we move into early next week, we may see yet another late season cold front approaching, which could turn our winds light again, from the southeast…which means there could be another brief round of voggy weather.
Satellite imagery shows remnant moisture from the late season frontal boundary…draped along our windward sides. Looking at this larger satellite image, we see that this cloud band is bringing its remnant moisture over the area between the Big Island, Maui County, up through Oahu. At the same time we see areas of high cirrus clouds well to the southeast, southwest, and west of the state…being carried along in the strong winds aloft. Here’s a looping radar image, showing generally light showers falling, as they spread across our windward coasts and slopes, with the primary axis of showers over the eastern islands at the time of this writing.
Showers continue to fall along our windward sides, most notably from Maui County down through parts of the Big Island. This ragged frontal cloud band has stalled over Maui County and the Big Island, although showers extend back up to Oahu. The bulk of the showers that will hang on over the next couple of days, will be focused along our windward coasts and slopes…with a few sneaking over into the leeward sides at times. It appears that we’ll turn drier after mid-week, with the trade winds continuing to blow. The models show yet another late season cold front approaching the islands early next week, although it’s likely to stall before reaching Kauai around next Monday. This early next week front may be able veer out winds back towards the southeast again, bringing back volcanic haze again then. I’ll be back again early Tuesday morning with your next new weather narrative, I hope you have a great Monday night wherever you’re spending it! Aloha for now…Glenn.
Here on Maui, at the 3,100 foot elevation, at my upper Kula, Maui weather tower, the air temperature was 59.2 degrees at 610am on this Monday morning. Skies are mostly clear here in Kula, although looking over towards the windward sides, they are cloudy with showers falling. Those windward sides here on Maui, and on most of the other islands, will remain quite cloudy, with off and on showers continuing for the next couple of days. The island of Kauai is mostly out of this shower activity at the moment, as is the southern part of the Big Island generally too. This type of late season rainfall is very beneficial, as we head towards our dry summer season. This is especially true, given the fact that we have an El Nino weather pattern slated to arrive this summer into the fall months. El Nino is infamous for bringing drought conditions to the Hawaiian Islands! El Nino is also remembered as bringing larger than normal winter surf to our north and west shores…as well as a more active tropical cyclone season in the eastern and central Pacific.
We’re a little later into the morning now at 750am, with the windward low clouds having shifted into parts of Kula. These clouds are being blown over from the windward side…bringing a cool mist. The air temperature is 67.6 degrees, with this cool breeze getting my wind chimes going pretty wildly at times.
It’s now 1230pm, under clear to partly cloudy skies, with occasional gusty winds, and an air temperature of 77.4 degrees. We had periods of light mist move overhead earlier today, although that has shifted back over towards the windward sides again. Glancing down country into the central valley, I can see that the clouds coming in off the ocean in Kahului and Wailuku, are then impacting the West Maui Mountain slopes…and being channeled over towards Maalaea Bay. The winds have become an issue today, in the wake of this cloud band, which is called a shear line in the met community. The NWS forecast office has issued a small craft wind advisory for the major channels between the islands, and the Maalaea Bay too. These gusty winds have been reaching 40 mph and more thus far today, while those areas with less exposure…are experiencing less windy conditions. Update at 2pm, its cloudy with light showers, with an air temperature of 76.8 degrees. Another update now at 230pm, it’s steadily raining, with an air temperature of 72.7 degrees.
It’s now early evening at 540pm, under mostly clear skies, light breezes, and an air temperature of 74.1 degrees. My neighbor just got back from a quick trip down to Makawao town, and found wet and windy weather there…which is just 10 minutes down the road from here. I’m excited about dinner this evening, as I sauteed shallots, organic butter and olive oil in a pan, along with some rosemary…before adding a package of skinless, boneless organic chicken thighs. At the same time, I put organic red potatoes (quartered), and sliced zucchini in my toaster oven, with olive oil dribbled on it, and a bit of rosemary on those too. It all turned out great, and rather than having a glass of white wine with it, I’ll pour a glass of zinfandel to have with it as well. I’ve popped a 2012 Saldo, from the Prisoner Wine Company. The word “saldo” has various meanings throughout the romance languages of Spanish, Italian and Portuguese. In Spanish, it mainly refers to “balance on hand,” and sometimes it can also be interpreted “from here and there.” This ruby red Zinfandel blend represents the very best lots of grapes from vineyards all across Northern California. Bold in its dark berry aroma and laced with hints of cardamom and fall spices, its finish has persistent notes of chocolate and rich coffee bean.

Interesting: Industrial-sized rain barrel research in Washington State – In an effort to reduce the amount of polluted runoff reaching Puget Sound, the Port of Seattle is hosting a two-year study site for two unique metal boxes, which will bloom into rain gardens and help reduce pollutants.
“The Port of Seattle is working with many partners to restore Puget Sound.” said Commissioner Bill Bryant. “There is no single solution to saving Puget Sound, no silver bullet, but there are hundreds of different things we can do and this is one of them.”
Moving Green Infrastructure (MGIF) is a research/demonstration project to test the water quality performance of two innovative storm water treatment techniques, a large “rain garden in a box” and a special soil mix with local, volcanic sands. Water quality from a roof in an industrial port area will be tested before and after going through the boxes to see how these two techniques perform. This research/demonstration project is part of growing efforts to reduce the amount of polluted runoff reaching Puget Sound, which is estimated to receive between 14 and 94 million pounds of toxic pollutants every year. Two large steel boxes, called Splash Boxxes, are being installed at Terminal 91. These boxes are a blend of rain garden and cistern, two practices referred to as low impact development, or LID.
“LID works,” said Amy Waterman of Gealogica, “resulting in 98-99% reduction in runoff volume and 83-99% reduction in key pollutants.”
The information from this study will help shed light on the potential for these bio-retention planter boxes to improve water quality of polluted runoff in commercial/industrial areas and whether soil mixes used in rain gardens and bio-swales could be improved. One box is going to have a unique soil mix with volcanic sands and the other will be a typical rain garden soil mix.
“We developed Splash Boxx for just this type of industrial application,” said David Hymel of Splash Boxx LLC. “We are very pleased to be able to provide the delivery system that tests an exciting new bio retention soil mix design.”
“King Conservation District in partnership with Seattle Public Utilities supported this project with a grant for $49,700 because we think it is important to explore innovative solutions for our storm water issues,” said Sara Hemphill, Executive Director, King Conservation District.
The water going into each box from the roof runoff will be tested once a month during the rainy seasons for phosphorus, nitrogen, bacteria, zinc, and copper. Splash Boxxes are part of an innovative storm water research and demonstration project funded by King Conservation District and managed by Sustainable Seattle through a contract with Gealogica LLC. The Port of Seattle is providing the site for two years.
