Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (nearly 13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the Haleakala Crater 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.

High Surf Advisory…for east facing shores of Kauai, Oahu, Molokai, Maui and the Big Island

Small Craft Advisory…windiest coasts and channels Maui County and the Big Island

Flash Flood Watch…statewide

 

Broad Brush Overview: Partly to mostly cloudy skies, along with the trade winds will continue across the state, due to a strong high pressure system located far to the north, and an upper trough positioned several hundred miles west of Kauai. Satellite imagery continues to show considerable middle to upper level moisture being drawn northward…which continues to limit our sunshine during the days.

Although most of the light precipitation from these clouds will continue to focus over the windward and mountain locations, heavier showers over Kauai and Niihau and Oahu are likely. Latest radar showed moderate to heavy showers with a few thunderstorms moving in from the west over Niihau and Kauai at the time of this writing.

Details: Unsettled conditions will develop Friday into the weekend, as a trough moves into the area, bringing a threat for heavy rainfall and a few thunderstorms across the state. Despite some model inconsistencies, most continue to show low pressure developing along an approaching trough in the vicinity of the islands later Friday into Saturday…with an abundance of deep moisture being drawn northward.

This deep tropical moisture will likely lead to a wet weekend with a few thunderstorms, especially late Friday through Saturday. The best chance for the heaviest rainfall and thunderstorms will remain over the western end of the state late Friday into Friday night, then shifting eastward to Maui County and the Big Island Saturday and Saturday night.

Looking Ahead: As we push into Sunday through early next week, improving conditions are expected as drier air arrives over the state, and the upper trough and surface low lift away from the island chain. The models depict light westerly breezes, potentially giving way to overnight land breezes and afternoon sea breezes by early next week.

Marine environment details: The large northeast swell has peaked, and will slowly diminish…although is expected to diminish at a faster pace starting tonight.

No other significant swells are expected through the rest of the forecast period. The fading NE swell will be reinforced by a small to medium swell from the north-northeast between Saturday night and Monday. This swell will be followed by a small to medium northwest swell between Sunday night and Tuesday. South facing shores can expect a slight rise in the surf Friday, when a small southwesterly swell arrives.

Interesting: Ocean plastic could triple in decade – The amount of plastic in the ocean is set to triple in a decade unless litter is curbed, a major report has warned.

Plastics is just one issue facing the world’s seas, along with rising sea levels, warming oceans, and pollution, it says.

But the Foresight Future of the Sea Report for the UK government said there are also opportunities to cash in on the “ocean economy”.

They say this is predicted to double to $3 trillion by 2030.

The report says much more knowledge is needed about the ocean. The authors say the world needs a Mission to “Planet Ocean” to mirror the excitement of voyaging to the moon and Mars.

The Foresight reports are written by experts to brief ministers on medium and long-term issues of significance. This one has been signed off by ministers from four different departments as the authors emphasize the need for a joined-up oceans policy.

One of the authors, Prof Edward Hill from the UK National Oceanography Center told BBC News: “The ocean is critical to our economic future. Nine billion people will be looking to the ocean for more food. Yet we know so little of what’s down there.

“We invest a lot of money and enthusiasm for missions to space – but there’s nothing living out there. The sea bed is teeming with life. We really need a mission to planet ocean – it’s the last frontier.”

Another of the authors, the chief scientist for the UK government’s environment department Ian Boyd, agreed: “The ocean is out of sight, out of mind,” he said.

He told BBC News: “There’s a continuous process of exploring for new things to exploit in the oceans, and that’s happening faster than we scientists can keep up with. My suspicion is legislation is also struggling to keep up – and obviously there are risks in that.”

He said offshore wind farms, oil industries and mining firms were spreading into unexplored areas. “Scientists need to get in there faster than the commercial people or at least at the same time – to put proper regulation in place to govern those industries.”

The report highlights many concerns, including the current worry about ocean plastic litter, which it forecasts will triple between 2015 and 2025.

But it stresses that the ocean is being assailed from many different types of pollution – including run-off pesticides and fertilizers from farms, industrial toxins like PCBs, and pharmaceuticals.

The authors say if governments can identify ways of protecting biodiversity in the seas, there are riches to be harvested – including nodules of metals and possibly even cures for cancer.

They predict that the biggest industrial growth in the seas will come from offshore wind, followed by marine aquaculture and fish processing. The report also projects an increase in industrial capture of wild fish.

This latter suggestion alarmed Rachel Jones, a marine expert from London Zoo, ZSL. She told BBC News: “Given that 90% of global fisheries are either at or in excess of sustainable catch levels, I can’t really see how they are going to expand capture fisheries.”
