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: An approaching cold front will being enhanced showers and isolated thunderstorms to the western end of the state through Monday night. Unsettled wet conditions continue through most of next week, as another cold front approaches from the northwest, then stalls across the western half of the state.

Hawaii’s Weather Details: Satellite imagery and the latest surface analysis depicts a cold front getting close to Kauai, and will reach the Garden Isle this evening. Radar imagery shows scattered showers across the leeward Kauai and Oahu waters moving northeast, but generally remaining offshore. Southerly winds ahead of the front continue across the state, with broken to overcast skies over leeward portions of the smaller islands.

The forecast remains on track, and continues to show the potential for heavy rain and isolated thunderstorms capable of producing flash flooding across portions of Kauai County and Oahu. A Flood Watch remains in effect for Niihau, Kauai, and Oahu from midnight tonight through 6am Tuesday morning.

The latest hi-res guidance shows the front reaching Kauai around midnight tonight, then moving eastward and reaching Oahu around daybreak on Sunday. The front looks to then briefly stall over East Oahu Sunday afternoon and evening, before retrograding west and stalling in the vicinity of Kauai or Oahu Sunday night into Monday. There remains good agreement with the evolution of the upper level support associated with the system, as a strong 100+ knot southwesterly jet stream helps to deepen the front and provide a narrow corridor of strong uplift.

This in turn will result in a mature jet stream-frontal system, that will support the development of a band of heavy rain and isolated thunderstorms. There still remains some uncertainty where this band of heavy rain will eventually settle Sunday night into Monday, but the western half of the state could see anywhere from 1.5 to 3 inches between now and Monday night, with locally higher amounts possible.

The upper level support is expected to lift north on Tuesday and bring the surface low with it. The surface front will also lift and weaken, although lingering moisture will remain in the area, keeping some showers around the area on Tuesday. Another surface low looks to develop near the dateline on Monday, then move east through late next week.

Guidance continues to show a front approaching the islands from the northwest mid to late next week, with the front elongating and stalling over the western half of the state by late next week. There is still some uncertainty with how strong this front will be, but expect additional showers and unsettled weather continue through the rest of the 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.
