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: A cold front passing far north of the Hawaiian Islands will weaken the high pressure ridge just north of the state, keeping light to moderate trade winds in the forecast lasting into Wednesday. Brief passing showers are possible in this weather pattern, favoring the late afternoon to early morning hours.

A stronger cold frontal low pressure system moves into the Central Pacific basin on Wednesday, driving the ridge axis directly over the island chain, and producing light east to southeasterly winds. The forward motion of the front will likely stall and diminish west of Kauai over the weekend.

Hawaii’s Weather Details: The weather pattern over the Hawaiian Islands appears to be fairly stable. Temperature inversion heights are around the 5,000 to 6,000 foot level, supporting brief passing showers favoring the windward and mountain areas. We continue to see a high pressure ridge just north of the islands, with cold frontal systems passing by farther to the north. These low pressure systems will continue to weaken the ridge this week, keeping trade winds in the light to moderate range lasting into Wednesday.

By Wednesday evening, this subtle weather pattern changes once again, as a stronger cold frontal low moves through the Central Pacific basin. Colder air surrounding this system will drive the weakened ridge farther south, with the ridge axis hovering directly over the Hawaiian Islands from Thursday to Friday. Lighter east to southeasterly winds will develop from Thursday onward into the weekend, expanding the coverage of daytime sea breezes to all islands.

Not much in the way of showers during this time period, as the ridge over the islands keeps conditions fairly stable. One exception to this rule will be along the southeast slopes of the Big Island, where southeasterly wind flow will lift clouds up the slopes of Mauna Loa, enhancing clouds and showers over Kau and Puna Districts.

These lighter winds will continue through the weekend, as the forward movement of an approaching cold front appears to stall as the boundary dissipates just west of Kauai. Light southerly winds may increase shower activity over Kauai and Niihau from Saturday to Sunday. Model solutions are fairly inconsistent from run to run on these enhanced shower impacts.

The rest of the state appears on the drier side in an east to southeast wind, and a hybrid sea breeze pattern during the day over each island. Another stronger cold front approaching the islands from the west may bring another round of wet weather with southerly winds by early next week, stay tuned.

Fire weather:  Winds and humidity levels will remain below critical fire weather thresholds this week. Brief passing showers will trend higher during the typical late afternoon to early morning hours. Temperature inversion heights will range from 5,000 to 6,000 feet elevation near Maui and the Big Island.

Hawaii’s Marine Environment:  The pressure gradient back to the surface high centered far northeast of the islands will weaken as the high moves east. Thus, moderate to locally fresh easterly trade winds will begin to fall off through the week. A large North Pacific storm will push a cold front to the vicinity of Kauai and Niihau by the weekend. The approach of the front will weaken and veer winds more southerly through the holiday.

The tail end of this front will likely pass north of the island chain early next week. A decent size northwest swell passage over Thanksgiving may push seas to near Small Craft Advisory thresholds. A large northwest swell will likely lift seas to SCA heights by this time next week.

Moderate size, medium period northwest swell (320-340 degree) will continue to fall through Tuesday. This will result in near head high surf over better northern exposures, before falling to waist high by Tuesday. A slightly larger size, long period northwest swell (330 degree) is scheduled to arrive Wednesday, fill in and peak on Thursday. This swell will result in solid High Surf Advisory level surf with the possibility of surf just touching High Surf Warning heights during its peak Wednesday night into Thursday morning. A large storm force low moving up from the West Central Pacific may drive a very large northwest swell toward the islands late this week. As of now, this swell is forecast to arrive early next week, and could generate XL size surf along north-facing shores.

Interesting: Creating an Extension-Driven Vision for Smarter Farming

With a project list that includes machines, drones, artificial intelligence and robots, it might seem that Luan Oliveira’s research is far from the fields that support Georgia’s No. 1 industry, agriculture. On the contrary, growing up in Brazil in a family devoted to farming and business sparked his passion for agricultural engineering and precision agriculture.

“Because of my upbringing, I’ve always been exposed to farming operations, directly and indirectly,” said Oliveira, precision agriculture specialist for University of Georgia Cooperative Extension. “When I was in my early teenage years, my father opened a small auto parts store, and I learned the machinery side, since we were selling parts for local farmers.”

When he arrived at Brazil’s Federal University of Paraíba for his undergraduate program in 2011, Oliveira knew he liked two things: machines and agriculture.
