Hawaii’s Mountains – Here’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.
Low pressure system with a cold front north and northwest of
the islands…more cirrus looming to our southwest
Mostly clear to partly cloudy…increasing clouds to the
south through east heading towards the state, first
on the Big Island, more high cirrus clouds too
A few showers…mostly to the south through east of the Big Island –

~~~ Hawaii Weather Narrative ~~~
Trade winds will continue…although remaining lighter than normal for another couple of 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 profiler of the central Pacific. We find moderately strong high pressure systems far to the northwest and northeast of the state. At the same time, there’s a low pressure system to the north, along with its associated cold front and trough. Our trades will remain on the softer side of normal, especially over Kauai and Oahu, with onshore daytime sea breezes, and offshore flowing land breezes during the nights. This unusual weather situation is being caused by the relatively close proximity of the low pressure system to our north and its associated cold front and trough. We should see rebounding trade winds a little later this week…remaining well established into the weekend and beyond.
We’ll see showers popping-up over the islands during the afternoon hours…locally. The windward sides will still see a few showers, although not many are expected, and mostly during the nights. As the trades remain rather soft for the time being, we’ll see a convective weather pattern continuing. This will manifest as afternoon upcountry clouds leading to localized showers, clearing back during the nights for the most part. An area of moisture is looming to the east through south of the state, which will bring increased shower activity tonight into Wednesday, especially over the Big Island and Maui. This temporary increase in local showers over the eastern islands, should be followed by a more normal passing shower regime along our windward sides. I’ll be back with more updates on all of the above, I hope you have a great Tuesday wherever you’re spending it! Aloha for now…Glenn.
Here on Maui…it’s 6am Tuesday morning, with mostly clear conditions, along with a bit of light haze in the central valley as well. The air temperature here in Kula, at my upcountry weather tower was 54.3 degrees, while it was 70 down at the Kahului airport, 75 out in Hana…and 46 up at the summit of the Haleakala Crater at near the same time.

Interesting: How Rainwater Could Save Rupees – Rainwater could save people in India a bucket of money, according to a new study by scientists looking at NASA satellite data.
The study, partially funded by NASA’s Precipitation Measurement Missions, found that collecting rainwater for vegetable irrigation could reduce water bills, increase caloric intake and even provide a second source of income for people in India.
The study, published in the June issue of Urban Water Journal, is based on precipitation data from the Tropical Rainfall Measuring Mission (TRMM), a joint mission between NASA and the Japan Aerospace Exploration Agency, which provided observations of rainfall over the tropics and subtropics from 1997 to 2015.
“India has severe problems getting potable water to all of its residents,” said Dan Stout, research assistant in the Department of Civil Engineering at the University of Utah and one of three authors of the study. “We considered collecting water in a relatively small tank, and it’s amazing the effect that doing something that small and simple can have on the Indian people.”
Rainwater harvesting is not a new concept, but the team said it is currently a largely untapped resource in India. Other researchers have studied rainwater harvesting as a potential solution for the country’s water problems, but they mostly focused on its use to replenish groundwater levels, which does not provide any direct benefit for immediate water supply. The water must run off into the ground before being pumped again for use aboveground.
Here, the team examined the possibilities if Indians collected precipitation in cheap 200-gallon tanks that they could easily engineer to fit in densely populated urban areas, such as many of India’s growing cities. The team analyzed satellite data of precipitation in different areas to evaluate the availability of rainwater for direct harvesting—information that would have been nearly impossible to obtain if not for TRMM.
“I spent a decent amount of time trying to find precipitation data in India,” Stout said. “For the most part, it didn’t exist or was kept under lock and key, aside from annual accrued averages across large regions of the country. That was not at all sufficient. Before I found TRMM’s data, I was thinking we would have to drop the project.”
TRMM precipitation estimates show the variation in rainfall at 3.1-mile resolution, even in areas where ground measurements are non-existent.
