Hawaii’s MountainsHere’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.

Hawaii’s Broad Brush Weather Overview…as of 310pm MondayAfter showers and isolated thunderstorms depart the Big Island tonight, an upper level ridge will move in, and bring a return to cooler and drier trades from Tuesday through Thursday. Winds will veer to southeast Friday and remain that way into the weekend, bringing warmer temperatures and a sea- and land-breeze pattern. Sunday night into early next week has the potential for another trough with another wet pattern.

Hawaii’s Weather Details…as of 308pm Monday: The Flood Watch which had been in effect for Maui County, where only light showers remain, has been cancelled. Radar shows stronger showers and isolated thunderstorms over the Big Island. The thunderstorms were located near Volcano. Breezy to locally windy trade winds have developed, and are expected to remain over the area through Thursday. This will bring additional showers over the next few days, mainly windward and mountains, as usual.

An upper level ridge will finally replace the trough that has brought significant rains to the area in recent days. As the trough moves out to the east tonight, it will take any remaining thunderstorms with it. Tuesday through Thursday we will see a typical trade wind pattern. Drier and cooler air will be carried into the region. This will allow for cool mornings in areas sheltered from the trades.

As the upper level ridge axis moves east of the state Thursday night into Friday, our low level flow will veer and become southeasterly. This will begin to slowly increase low-level moisture. As wind speeds weaken, sea- and land-breezes will develop this coming weekend. This pattern typically results in showers forming both windward and leeward. Long range models show the potential for a trough to bring an increase in showers Sunday night or Monday of next week.

Hawaii’s Marine Environment…as of 348am Monday: A trough over the central coastal waters will slowly push southward due to the strong high pressure far north of the islands. Currently, gentle westerly winds are south of the trough, while fresh to strong easterly winds prevail north of the trough. Scattered moderate showers and isolated thunderstorms can be expected near and along the trough. A Small Craft Advisory (SCA) is in effect for waters surrounding Kauai, due to fresh to strong trade winds, and will be expanded and extended even though the winds should ease slightly tonight and Tuesday, but due to a large north-northeast swell expected to produce seas in excess of the SCA threshold over most waters into Tuesday night. Moderate to locally fresh trades are expected on Wednesday, giving way to southeasterly winds Thursday or Friday as a front approaches.

Surf along north facing shores will build due to a northeast (010-030 deg) moderate long period swell that has begun to show forerunners at NDBC buoy 51000. As the swell builds, it will produce breaking waves at High Surf Warning levels across most north and east facing shores during the peak tonight and Tuesday. Due to the direction of the large swell, exposed west facing shores of West Maui, western Molokai, and North Kohala on the Big Island will likely experience High Surf Advisory waves. The north-northeast swell will gradually decline Tuesday night through Friday. In addition to this swell, a small pulse of overlapping west-northwest swell is expected to build and hold through Wednesday.

Due to the direction of the large north-northeast (010-030) swell, some overwash will be possible along low-lying coastal roads and infrastructure in windward areas, and hazardous conditions and heavy surges are expected in north facing harbors, mainly in Hilo and Kahului.

Very small wintertime surf will continue along south facing shores this week.

Interesting:  Climate Change and Persistent Contaminants Deliver One?Two Punch to Arctic Seals, SFU Study Finds

New research shows a single year of warmer-than-average Arctic temperatures can cause malnutrition in Arctic seals, intensifying risks to Inuit food security and northern ecosystems already under pressure from environmental toxins, warn Simon Fraser University researchers.

The SFU study found Arctic ringed seals are struggling to clear persistent contaminants and banned pesticides from their bodies — a long?term health risk made worse when climate?driven changes to sea ice and temperatures limit their access to nutrient-rich food.

“Ringed seals are a crucial link between invertebrates, fish and apex predators, and they are a cornerstone of northern food systems,” says Tanya Brown, marine mammal ecotoxicologist and senior study author. “We’ve found that warmer conditions can change what they feed on, which changes their contaminant exposure, and that can affect their overall health and survival.”
