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.

Hawaii’s Broad Brush Weather Overview: Southerly winds will be on the increase today ahead of a front approaching the islands from the northwest. The front will bring enhanced showers and isolated thunderstorms to the western end of the state Sunday through Monday night. Additional unsettled wet weather will be possible during the middle and latter half of next week as another front approaches, then stalls across the western half of the state.

Hawaii’s Weather Details: Unsettled weather remains the main story for the forecast for much of the next week. Southerly winds are expected to increase over and near Kauai today, reaching Small Craft Advisory (SCA) levels.

A trough to the northeast will continue to move away from the islands, as a front to the northwest moves closer to the islands. There is good model agreement with the models with this front holding together as it approaches Kauai later today. Winds are expected to increase ahead of the front.

The front is expected to reach Kauai late tonight, and move toward Oahu on Sunday, before stalling in the vicinity of Kauai or Oahu Sunday night into Monday. There is good agreement in the models with the handling of the upper level dynamics with this system, with a strong southwesterly jet stream helping to push the surface front towards the islands, and provide additional instability that could result in locally heavy rainfall and isolated thunderstorms. Although uncertainty remains as to the exact location where any bands of heavy showers may form, a Flood Watch continues for Kauai, Niihau, and Oahu from midnight Sunday through late Monday night.

The upper level feature is expected to lift out Tuesday, and bring the surface low with it. The surface front will also lift and weaken, although lingering moisture will remain in the area. Another surface low forming well to our west Monday, is expected to approach the islands during the middle to latter part of the new week. The will bring another front to the area from the northwest, and it too is expected to stall over the western end of the state. There is still some uncertainty with how strong this front will be, but expect additional showers to continue through the rest of next week.

Fire weather:  Conditions will remain below critical fire weather thresholds through the forecast period. Winds are expected to remain light to moderate, with relative humidity steadily increasing as a front approaches from the northwest, then stalls over the western end of the state Sunday and Monday. Additional showers chances expected mid to late next week as another front approaches, then stalls across the western half of the state.

Hawaii’s Marine Environment: An approaching front moving southeast is expected to arrive on the doorstep of Kauai and make its way over the western end of the state this weekend. Gentle to locally strong south winds are expected with strong south to southwest winds over mainly Kauai waters. A Small Craft Advisory has been issued over select Kauai waters before the winds are expected to ease Sunday. Showers and the potential for isolated thunderstorms are expected along the front through Sunday.

A surface low far northwest of the offshore waters will develop early next week, and will likely send another front to the islands that guidance is showing will stall over the western end of the state. There is still some uncertainty with how strong this front will be, but expect additional showers and isolated thunderstorms to continue through the forecast period mainly over the western waters. Gentle to locally fresh southerly winds are expected Sunday through the forecast period as the surface low develops northwest of the islands.

The current north swell has declined and will plateau at moderate levels through the weekend. A new moderate medium to long period northwest swell is expected to fill in and peak Sunday near or at High Surf Advisory level criteria for north and west facing shores before gradually declining Monday. A combination of moderate northwest and north swells will keep surf elevated through the first half of next week.

East facing shores will remain tiny to small given the lack of trade winds but shorelines exposed to the north swells may be slightly elevated through Wednesday. Surf along south facing shores will see an increase of short period wind wave chop mainly over the western islands this weekend associated with the passing front. A slight lull is expected Sunday before the next front approaches and increases the wind waves coming from the south.

Interesting: Polar Bears May Be Adapting to Survive Warmer Climates, Says Study

New research reveals a link between rising temperatures and changes in polar bear DNA, which may be helping them adapt and survive in increasingly challenging environments.

The study by scientists at the University of East Anglia (UEA) discovered that some genes related to heat-stress, aging and metabolism are behaving differently in polar bears living in southeastern Greenland, suggesting they might be adjusting to their warmer conditions.

The finding suggests that these genes play a key role in how different polar bear populations are?adapting or evolving?in response to their changing local climates and diets.
