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.

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 increasing over the next few days. 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 moderately strong high pressure systems, coming in at near 1024 millibars, located to the north-northwest and northeast of the state. There will be no interruption in our trade wind flow during the foreseeable future.

Satellite imagery shows scattered clouds around the islands…although they will increase again tonight and into early Tuesday morning.
Looking at this larger looping satellite image, shows low level clouds riding along in the trade wind flow…coming in from the east. Here’s a looping radar image, showing passing showers,  over parts of the Big Island at the time of this writing. The windward sides will be on the receiving end of most of these showers, although the leeward sides will collect a few showers on the smaller islands too. 

This trade wind weather pattern will continue. We have a trough of low pressure, located not far to our east. This zone of low pressure is helping to enhance some of the showers that are falling locally, or at least will again tonight in some places. The leeward beaches, as is often the case under these conditions, will have much fewer showers, although could see a few here and there during the cooler nighttime hours. 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 60.8 degrees at 550am on this Monday morning. Skies are cloudy in many areas for a change, with showers falling from these clouds locally. I just got a text from a friend in Spreckelsville, and she said it was raining there. Looking out on my weather deck, I can see that there’s been some light mist falling here too. This is a nice change of pace, especially during the month of June…our driest month of the year.
It appears to be getting the central valley, even moving over Kahului and Wailuku…although not reaching the Kihei and Wailea areas. Update at 720am, clear to partly cloudy skies, near calm winds…with an air temperature of 63.9 degrees. Those early morning clouds and showers that spread over some parts of Maui, have now pulled back to the windward sides generally.

We’re into the early afternoon now at 1220pm, under sunny skies, light winds…and an air temperature of 78.8 degrees. After a rather cloudy start to the day, and those passing showers around in many places, things have taken a turn for the better as we’ve slid into the afternoon time frame. There are mostly sunny skies that have replaced the earlier clouds, making for a great looking day! Update at 3pm, it was just 85.8 degrees here in Kula, which is one of the hottest days I can remember. It’s just cooled off a little, having backed down to 84.4 degrees. The skies are totally sunny all over Maui, hardly a cloud in the sky. Interestingly enough, at the about the same time, it was 72 degrees in Hilo on the Big Island…where it’s been raining much of the day.

It’s now 540pm under totally clear skies, light breezes…and a very warm 83.1 degrees. This was a very hot day up here, even a bit hotter than some places down near sea level. Hilo on the Big Island in particular, was quite cool with passing showers much of the day. Inside my weather tower at the moment, the inside temperature was 87.4 degrees…while it was still 83 outside in broad daylight. This is way too warm for me, as I prefer cooler temperatures most of the time. I’ve made it through the day, although it was quite a push I must admit. Unusual…a friend just send me a text, along with a picture of a small waterspout offshore from a beach on the Lahaina side! Update, Hilo and Kailua Kona on the Big Island were both reporting rain at 543pm, with unusually cool air temperatures of 72-75 degrees.

Here’s a satellite image of the Atlantic Ocean

Caribbean Sea:
There are no active tropical cyclones expected through the next 5 days

Gulf of Mexico:

North Eastern Pacific:
There are no active tropical cyclones

A low pressure system is expected to form to the south of Mexico
late this week, and development of this system is possible by the
weekend while it moves west-northwestward.

* Formation chance through 48 hours…low0 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: Update: the future of EV’s in China China has ambitious goals for developing and deploying electric vehicles (EV). The stated intention is to “leapfrog” the auto industries of other countries and seize the emerging EV market. Since 2009, policies have included generous subsidies for consumers in certain locations, as well as strong pressure on local governments to purchase EVs. Yet four years into the program, progress has fallen far short of the intended targets. China has only about 40,000 EVs on the road, of which roughly 80% are public fleet vehicles such as buses and sanitation vehicles. China’s EV industry faces the same challenges as companies in the West: a) high battery costs; b) inadequate range between charges; and c) no obvious infrastructure model for vehicle.

China’s EV industry faces the same challenges as companies in the West: a) high battery costs; b) inadequate range between charges; and c) no obvious infrastructure model for vehicle charging.

In addition, China’s industry is constrained by four domestic barriers.

China’s fragmented automobile industry lacks the capacity to acquire or develop world-class EV technologies. To date, attempts to induce foreign companies to transfer technologies via joint ventures have been largely unsuccessful.

Trade barriers prevent foreign firms from producing or selling EVs in China. Not only are imported cars ineligible for subsidies, there are also stringent IP transfer requirements for domestic sales of foreign-branded EVs and other “new energy vehicles.” Equally important as the international barriers, trade barriers at the city- and province-level prevent an efficient allocation of the EV manufacturing and supply chain within China.
