Air Temperatures – The following maximum temperatures (F) were recorded across the state of Hawaii Friday:
85 Lihue, Kauai
88 Honolulu, Oahu
89 Kahului, Maui
87 Kailua Kona
83 Hilo, Hawaii
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.
Our trade winds will continue, becoming a little lighter
later this weekend into early in the new week
Some showers…primarily along our windward sides, before
heavy rains and muggy weather arrives later today, first
on the Big Island and Maui…into Monday - look for localized
thunderstorms and flooding
This looping satellite image shows the clouds in our area
Flash Flood Watch…state of Hawaii – 6pm today
through 6pm Monday
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 remain active…generally blowing in the moderately strong range. 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 to the north of the state, along with a ridge running by to our north and northwest. The forecast calls for the winds to remain active through this weekend. Meanwhile, a large area of tropical moisture will move over the state from the southeast and east. This area is associated with former tropical cyclone Wali…which is migrating westward.
Satellite imagery shows a large area of showery clouds moving into the state from the southeast. Looking at this larger looping satellite image, it shows this threatening area of low level clouds riding along in the trade wind flow. Here’s the looping radar, showing passing showers moving across our area, taking aim on the Big Island. These showers will fall in the light to moderately heavy range at first. We’ll see increasing showers, first on the Big Island and Maui, then spreading to the rest of the state Sunday through Monday. As an upper level low pressure system comes into play, these showers will gain intensity with time…leading to heavier showers and the likelihood of flooding.
The primary focus through the next couple of days…will be on the arrival of this large slug of tropical moisture. The first tropical system of the summer, which began in the eastern Pacific, is now lost all of its winds. However, now remnant low pressure system will bring very moist air over the state. This in turn will bring lots of rain with localized thunderstorms…and a definite threat of flooding in places. It will take until Tuesday or so before this inclement weather situation moves to the west of Hawaii. I’ll be back with more updates on all of the above. I hope you have a great Saturday wherever you’re spending it, Aloha for now…Glenn.

Interesting: Rainwater discovered below the Earth’s fractured upper crust – When it rains, where does the water go? Well for one, a lot of rainwater will funnel its way off roads and impermeable surfaces and will make its way into storm sewers. Another path might be directly into rivers and lakes. Or, rainwater might get soaked up by soil where it will then infiltrate into the ground and replenish aquifers. But just how deep does this rainwater infiltrate?
According to new research, rainwater can penetrate below the Earth’s fractured upper crust – which is at least eight miles below the Earth’s surface!
It had been thought that surface water could not penetrate the ductile crust – where temperatures of more than 300°C and high pressures cause rocks to flex and flow rather than fracture – but researchers have now found fluids derived from rainwater at these levels.
The research could have major implications for our understanding of earthquakes and the generation of valuable mineral deposits.
Fluids in the Earth’s crust can weaken rocks and may help to initiate earthquakes along locked fault lines. They also concentrate valuable metals such as gold. The new findings suggest that rainwater may be responsible for controlling these important processes, even deep in the Earth.
Researchers from the University of Southampton, GNS Science (New Zealand), the University of Otago, and the Scottish Universities Environmental Research Center studied geothermal fluids and mineral veins from the Southern Alps of New Zealand, where the collision of two tectonic plates forces deeper layers of the earth closer to the surface.
The team looked into the origin of the fluids, how hot they were and to what extent they had reacted with rocks deep within the mountain belt.
“When fluids flow through the crust they leave behind deposits of minerals that contain a small amount of water trapped within them,” says University of Southampton researcher Catriona D. Menzies. “We have analyzed these waters and minerals to identify where the fluids deep in the crust came from … Although it has been suggested before, our data shows for the first time that rainwater does penetrate into rocks that are too deep and hot to fracture.”
