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 trade winds will be picking up through the rest of the week…right on into next week. 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 have a moderately strong high pressure system located far to our northeast…with its associated ridge extending southwest to the northeast of the state. There’s a second high pressure cell to the north, which has another ridge trailing it to the southwest. At the same time, we have a low pressure system well to the north, with its associated cold front/trough, the tail-end of which is located just to the north of Kauai and Oahu. Our winds will increase now…and continue well into the future.
Satellite imagery shows patchy lower level clouds mostly over the ocean…although coming into the windward sides in a few areas. Looking at this larger satellite image, we see a large area of high clouds being moved along on the upper level winds to our southwest, west along with a counterclockwise rotating upper level low pressure system far to the west-northwest. Some of these high clouds may move over parts of the state eventually. Here’s a looping radar image, showing light showers being carried along in our trade wind flow, although not many at the time of this writing. It appears that drier air is moving into our area from the east, which will tend to keep our shower activity tamped down at the moment.
We’re embarking into a well established trade wind weather pattern…which will bring generally fair weather our way. The windward sides, as the trade winds rebound now, will have off and on showers through the next week. The upper low pressure system to our west, and its associated instability, are far enough away now, that its influence is flagging. Our weather will follow climatology quite closely, which means the trade winds will be our major player, along with those off and on passing windward biased showers. I’ll be back early Wednesday morning with your next new weather narrative from paradise, I hope you have a great Tuesday 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 54.5 degrees at 545am on this Tuesday morning. Skies are mostly clear everywhere here on Maui, along with what looks like a bit of light volcanic haze too. It’s a lovely start to our day, with hardly a cloud in the sky!
It’s now 1235pm, under partly cloudy skies, light breezes, and an air temperature of 78.6 degrees. There’s still a bit of haze down in the central valley, somewhere between light and almost moderately thick. Scanning the horizon, I don’t see any showers, and here in Kula at the moment, the clouds look pretty dry for the most part.
We’re into the early evening hours now at 545pm, under partly cloudy skies, light trade winds, no showers…and an air temperature of 80.2 degrees. This is very warm for this time of the evening, and since we’ve had not a drop of rain all day, it looks quite likely that we’ve turned the corner into what our weather “should be like”…this time of year.
Here’s a weather product that I prepared for the Pacific Disaster Center this morning.

Interesting: US EPA Releases Clean Power Plan Proposal – The U.S. Environmental Protection Agency is releasing the Clean Power Plan proposal today. This is the first attempt to cut carbon pollution from existing power plants, the single largest source of carbon pollution in the United States.
“Climate change, fueled by carbon pollution, supercharges risks to our health, our economy, and our way of life. EPA is delivering on a vital piece of President Obama’s Climate Action Plan by proposing a Clean Power Plan that will cut harmful carbon pollution from our largest source–power plants,” said EPA Administrator Gina McCarthy. “By leveraging cleaner energy sources and cutting energy waste, this plan will clean the air we breathe while helping slow climate change so we can leave a safe and healthy future for our kids. We don’t have to choose between a healthy economy and a healthy environment–our action will sharpen America’s competitive edge, spur innovation, and create jobs.”
According to the EPA, power plants account for roughly one-third of all domestic greenhouse gas emissions in the United States. While there are already standards for the level of arsenic, mercury, sulfur dioxide, nitrogen oxides, and particle pollution that power plants can emit, there are currently no national limits on carbon pollution levels.
By 2030, the EPA is planning to:
– Cut carbon emission from the power sector by 30 percent nationwide below 2005 levels, which is equal to the emissions from powering more than half the homes in the United States for one year;
– Cut particle pollution, nitrogen oxides, and sulfur dioxide by more than 25 percent as a co-benefit;
– Avoid up to 6,600 premature deaths, up to 150,000 asthma attacks in children, and up to 490,000 missed work or school days—providing up to $93 billion in climate and public health benefits; and
– Shrink electricity bills roughly 8 percent by increasing energy efficiency and reducing demand in the electricity system.
Also included in today’s proposal is a flexible timeline for states to follow for submitting plans to the agency—with plans due in June 2016, with the option to use a two-step process for submitting final plans if more time is needed. States that have already invested in energy efficiency programs will be able to build on these programs during the compliance period to help make progress toward meeting their goal.
Today’s announcement marks the beginning of the second phase of the agency’s outreach efforts.
