Hawaii’s MountainsHere’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.

~~~ Hawaii Weather Narrative ~~~



Gusty trade winds becoming just a little lighter into the weekend…at least locally. 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 three moderately strong high pressure systems located to the northwest, north and northeast of the state. These high pressure cells have associated ridges extending far southwest and southeast of their centers. Our local winds will remain gusty for the time being, with those places with the most direct exposure to this wind flow reaching 35+ mph in gusts locally.  A fairly minor reduction in wind speeds will take place today into the weekend, and then rebound next week…continuing well into the future from there.

Satellite imagery shows just a few scattered clouds around the islands…with higher level cirrus to our southwest.
Looking at this larger looping satellite image, we see areas of high level clouds to our south and southwest. These high cirrus to our southwest look like they will move just to the south of the state on the upper winds.  In addition, there are areas of thunderstorms far west of Hawaii, with more far south in the Inter-tropical convergence zone (ITCZ) down close to the equator. Meanwhile, there are lower level clouds riding along in the trade wind flow…although as usual they have diminished greatly during the heat of the afternoon hours. Here’s a looping radar image, showing very few showers arriving across the state, especially over the central islands at the time of this writing.

The trade wind weather pattern will continue on this last day of our spring season, right on into the summer season…which starts tonight. There will be some showers reaching the windward sides of our islands, with just a few being carried over into the leeward sides…mostly at night. There will be a trough of low pressure aloft, getting somewhat closer to the state into early in the new week. This upper level low may enhance some of the showers that fall locally…especially along the Kona slopes during the afternoon hours. The leeward beaches, as is often the case under these conditions, will continue to have very nice weather. I’ll be back early Saturday morning with your next new weather narrative on the first day of summer, I hope you have a great Friday 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 56.1 degrees at 605am on this Friday morning. Skies are clear overhead and down through the leeward beaches. There are a few clouds hugging the windward sides this morning, which are stretching over the West Maui Mountains. There are a few very thin wisps of high cirrus, although not enough to do much sun filtering of our warm Hawaiian sunshine…which will be beaming down in most areas. All things considered, we’ll find great weather through this last day of the spring season, and then right on into the first weekend of the summer season. Update at 1110am, it was clear and sunny, breezier than normal…with an air temperature of 75.4 degrees.

We’re into the early afternoon hours now at 1255pm, under mostly sunny skies, occasional breezy conditions…and an air temperature of 79.9 degrees. Glancing around the island from up here in Kula, it’s hard to imagine a more beautiful day. I’m sure that all those folks who like to lay at the beach and get tan, are having no difficulty doing this that now. The winds have taken on a more northerly to northeasterly orientation now, which has this air flow funneling through the valleys and channels. Even up here in Kula, there are some occasional stronger gusts at times, which is different that it usually is this time of year.

We’re into the last few hours of the spring season now at 610pm…which started four months ago to this day in March. Here in Kula, its very sunny, exceptionally sunny, with just a few thin high cirrus clouds punctuating an otherwise clear sky. The gusty winds early in the day have subsided greatly, and are replaced by the current very light breezes…with an air temperature of 78.1 degrees. I don’t see any interruptions to this near perfect, let’s just call it early summer weather. This weekend will remain very pleasant, if not a bit hot in places, especially those areas outside the reach of the refreshing trade winds. 



World-wide tropical cyclone activity:


Atlantic Ocean: There are no active tropical cyclones expected through the next 5 days


A weak area of low pressure is located about 180 miles east of
Jacksonville, Florida. Shower activity associated with this
system is limited and environmental conditions are not conducive for
development as the low the moves northeastward away from the
United States coast.


* Formation chance through 48 hours…low…near 0 percent.

* Formation chance through 5 days…low…near 0 percent.

North Eastern Pacific:
There are no active tropical cyclones

Shower and thunderstorm activity associated with a low pressure
system located about 700 miles south-southwest of Manzanillo,
Mexico has become a little less organized during the past several
hours. Although this system still has some potential for
development today or Sunday, upper-level winds are becoming
increasingly unfavorable for tropical cyclone formation while
the system moves northward at 5 to 10 mph


* Formation chance through 48 hours…medium…30 percent.
* Formation chance through 5 days…medium…30 percent.


Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.

Interesting: Over $1 Billion Pledged to Protect Marine Habitats – ‘Our Ocean’ 2014 brought together leaders from business, government and academic institutions, and NGOs from over 80 countries to discuss how economic development and ocean conservation can be reconciled. The oceans are extremely important for humans, generating more than 50 percent of the oxygen we breathe, absorbing excess carbon dioxide, and providing a source of food and income for millions of people worldwide.


The summit concentrated on several key themes in ocean conservation including sustainable fishing, marine pollution, and ocean acidification. Perhaps one of the most significant announcements at Our Ocean was President Obama’s intention to expand and create new marine reserves in the Pacific Ocean, while Kiribati announced it will expand its already vast Phoenix Islands Protected Area. If implemented, these proposals will more than double the total area of legally protected oceans.


Many of the world’s fish stocks are being fished at unsustainable levels, and it is thought that around 30 percent of the world’s fisheries are over-exploited. The Our Ocean summit aimed to examine the steps fishery management authorities need to take to reduce, and ultimately end, overfishing and to mitigate adverse impacts on the broader marine environment. Initiatives proposed at the summit aim to end all overfishing on marine fish stocks by 2020, through a series of measures including increased transparency in allocating fishing rights, tougher enforcement of legislation and penalties for illegal fisheries, elimination of excess capacity in fishing fleets and minimizing bycatch.


To this end, President Obama has announced a comprehensive new national program on seafood traceability and openness which will allow customers in the United States to ensure that their seafood has been harvested legally and sustainably. Additionally, the United States launched the ‘mFish’ partnership, which will provide mobile devices to small-scale fisheries in developing nations with apps designed to access market and weather information and ensure accurate and easy catch reporting. Norway also pledged more than $150 million to promote fishery management and development abroad, including a new research vessel to train fisheries experts and managers around the world.
