Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars, and the sunrise and sunset too…depending upon weather conditions.

Glenn’s Sunday comments:  I’m here at home in upper Kula, Maui

450am Sunday morning, with breezy conditions, with cloudy skies here at my place, with the low temperature 60.5 degrees, along with the relative humidity 78%.

830am, still very cloudy and there are still showers falling here in Maui County, some heavy, while here at my place I’ve had one short light shower since I’ve been up.

10am, cloudy and our second shower of the day has arrived here at my place in Kula.

346pm, still mostly cloudy here on Maui, although there is some muted sunshine trying to happen.

Interesting Web blog…Mauka Showers – The March 11-15, 2026 Kona Low – Once in a Generation Storm?

 

Hawaii’s Broad Brush Weather Overview…as of 319pm Sunday: A remnant band of moisture covering Oahu to the Big Island stays in place through Monday night. An upper trough moving towards the islands will keep enhanced showers and isolated thunderstorms going into Monday morning across Maui County and Big Island, and Oahu to a lesser extent. As trades build in Monday, showers will begin to focus over windward and mountain areas.

Weather Details for the islands…as of 319pm Sunday: The kona low will move away to the northeast tonight, while the remnant band of moisture covering Oahu to the Big Island stays in place through Monday night. An upper trough moving towards the islands will keep enhanced showers and isolated thunderstorms going into the morning across Maui County and Big Island, and Oahu to a lesser extent. Therefore, the Flood Watch has been extended for Maui County and Big Island through the night. The Winter Storm Warning for the Big Island summits will also continue with a few more inches of snow expected above 12000 feet.

Numerous, but lighter showers will continue across Maui County and Big Island on Monday. Trade winds will begin filling in Monday west to east, reaching the Big Island by Tuesday. Once the trades arrive, the leftover clouds and showers from the kona low will shift into a more typical trade wind distribution, favoring windward and mountain areas, and much lighter than during the event itself. The moisture clears the islands by Wednesday, with drier trade wind weather expected into next weekend.

Hawaii’s Marine Environment…as of 319am Sunday: Bands of heavy showers and a few thunderstorms will continue to move over portions of the coastal waters, especially the eastern waters, as a kona low continues to impact the state. Prevailing southerly moderate winds continue across portions of the area as well. The low will lift farther north today, allowing light to moderate northerly winds to develop around Kauai, which will then veer to northeast and spread southward.

The northerly swell has peaked, and is slowly declining. A slight bump is expected from a small, building west-northwest swell that will peak today keeping surf elevated but below High Surf Advisory criteria. A small south swell is slowly declining and will continue to trend down into early in the upcoming week. Smaller surf is expected along south facing shores through the remainder of the week. Surf along east-facing shores remains elevated due to wrap from the north swell, and will be near HSA thresholds. This swell will slowly diminish through the rest of the weekend as well.

Interesting:  Ocean Bacteria Team up to Break Down Biodegradable Plastic

MIT researchers uncovered the roles of bacterial species from the environment as they consume biodegradable plastic.

Biodegradable plastics could help alleviate the plastic waste crisis that is polluting the environment and harming our health. But how long plastics take to degrade and how environmental bacteria work together to break them down is still largely unknown.

Understanding how plastics are broken down by microbes could help scientists create more sustainable materials and even new microbial recycling systems that convert plastic waste into useful materials.

Now MIT researchers have taken an important first step toward understanding how bacteria work together to break down plastic. In a new paper, the researchers uncovered the role of individual ocean bacteria in the breakdown of a widely used biodegradable plastic. They also showed the complementary processes microbes use to fully consume the plastic, with one microbe cleaving the plastic into its component chemicals and others consuming each chemical.
