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 ~~~

Trade winds remain active, moderately strong in most areas…then lighter breezes this weekend. 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 a moderately strong high pressure system far to the northeast of our islands. At the same time, we see a low pressure system far to our northeast, with an associated weak frontal boundary breaking through this ridge…located around the Big Island at the time of this writing. Our local winds will remain active, although lighter as we move into the weekend time frame. We may see another late season cold front approaching early next week, which could turn our winds light again, from the southeast…which means there could be another round of voggy weather.

Satellite imagery shows remnant moisture from the recent late season frontal boundary…draped mostly along our windward sides.
Looking at this larger satellite image, we see that this cloud band remains in place, keeping our windward sides generally cloudy for the time being…with more sunshine over our leeward sides in contrast. Meanwhile, we see areas of high cirrus clouds well to the south 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 Maui County and parts of the Big Island at the time of this writing.

Light showers and drizzle continue to fall locally…most notably from Maui County down over the Big Island. The bulk of the showers, which will stick around over another couple of days, will be focused along our windward coasts and slopes. It appears that the trade winds will continue to blow, although becoming somewhat lighter by the weekend. The models show yet another late season cold front approaching the islands later this weekend, although it’s likely to stall before reaching Kauai early next week. This front may be able veer out winds back towards the southeast again, bringing back volcanic haze then. I’ll be back again early Wednesday morning, 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 61 degrees at 6am on this Tuesday morning. Skies are mostly cloudy here in Kula, with a light shower falling, along with no wind to speak of. It’s interesting to start the day here in Kula, with so many clouds, and even this light shower. Typically, this leeward side of the mountain begins days under clear skies, with cooler temperatures…than the relatively warm 61 degrees that we find at the time of this writing. It seems like what would be a winter morning, if it weren’t May, and this temperature wasn’t in the 60’s. I suppose because I like all weather, I don’t mind having the day start off this way, and actually am enjoying this somewhat unusual weather we’re having now.

We’re into the early afternoon hours now at 1240pm, with clear skies, light breezes, and an air temperature of 79.5 degrees. The cloudy and light drizzle we had early this morning, has backed way off, leaving sunny skies this afternoon…at least so far. I can still see lots of clouds over along the windward side however, and over and around the West Maui Mountains too…which is stretching into the central valley as well.

It’s now 4pm here in Kula, with partly cloudy skies, occasional gusty winds, a tiny bit of mist…and an air temperature of 73.9 degrees.

We’ve pushed into the early evening hours now at 540pm, under mostly clear to partly cloudy skies, occasional breezes, and an air temperature of 79.9 degrees. Today was less cloudy and showery than what we saw yesterday, here in the upcountry area. Those gray low clouds continue to blanket the windward sides of east Maui, and I assume west Maui…although I can’t see it directly. It was a warm day up here, with my thermometer almost reaching 80 degrees…and it isn’t much below that at the time of this writing.

Here’s a weather product that I produced for the Pacific Disaster Center this morning.

Interesting: India, not China, has the world’s worst urban air pollution Breathing in urban India is hard: of the world’s top twenty cities with the worst air, 13 of them are found in India, according to a new analysis by the World Health Organization (WHO). Despite the attention recently given to Chinese cities for atrocious air pollution, many of India’s cities are actually worse when comparing annual averages of fine airborne particulates.

The WHO looked at PM2.5 or airborne particulates less than 10 micrometers in diameter over a calendar year; PM2.5s are considered especially dangerous because they are easily respirated into the lungs leading to health problems such as lung cancer, heart disease, asthma, and bronchitis.

Surveying 1,600 cities in 91 countries, the WHO found that New Delhi’s air was the worst in the world with average of 153 PM2.5 micrograms per cubic meter. Three other Indian cities—Patna, Gwalior, and Raipur—round out the top four, with Karachi, Pakistan as the fifth worse in the world.

None of China’s cities came in the top 20. In fact, the Chinese city suffering from the worst air pollution was Lanzhou at number 36. Beijing, which gets a lot of media attention, is actually number 77.

The WHO says that air pollution should not be more than 10 PM2.5 micrograms per cubic meter to be deemed safe. But more than 1,100 of the cities on the list had levels of 11 or above. New Delhi air was more than 1,500 percent above the recommended level, and Beijing’s nearly 800 percent. However the WHO cautioned that some of the world’s most polluted cities may not be on the list.

“Many cities in the world, including some expected to be among the most polluted, do not collect information or report on its outdoor air quality. WHO therefore cannot compare cities based on their levels of outdoor air pollution,” says the WHO.

Still the new analysis allows easy side-by-side comparisons and paints a broad picture of air pollution worldwide. Worryingly, the analysis found that 90 percent of the global urban population (based on these 1,600 cities) were exposed to unsafe air pollution.

Government scientists from India have bashed the analysis saying that New Delhi’s levels were too high and Beijing’s too low. But one of the scientists contested that New Delhi averaged about 110 micrograms over the year, which is still 1,100 percent above the recommended level and a level that would land it in the top 10.
