Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the (~10,023 feet high) 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.

Hawaii’s Weather Highlights…as of Wednesday afternoon: Breezy trade winds will persist through much of the week, with minor fluctuations as surface high pressure holds north of the state. Pockets of moisture moving in the trades will focus rainfall over windward and mauka areas, with showers briefly passing over leeward areas. An area of deeper moisture may enhance showers on windward Big Island and Maui County Friday and Saturday.

Weather Narrative…as of Wednesday afternoon: A ridge of high pressure north of the state is generating breezy trades across the state. Satellite and radar imagery show widely scattered, light to moderate showers focusing along windward and mauka areas, with frequent showers spilling over to leeward areas of the smaller islands.

The sounding profiles this morning are fairly elevated between 7,000 to 8,000 feet, with showers spilling over to leeward areas locally. For the past 6 hours, rainfall totals for leeward areas range from 0.10 to 0.24 inches for the smaller islands. Windward locations range from 0.20 to nearly 1.00 inch of rainfall for the wetter areas.

Breezy and stable trade winds will continue through today as the ridge remains north of the state. Showers should trend down this morning for the western half of the state, but pick up slightly for the eastern half of the state as an area of moisture sags south.

Little change is expected tonight through Thursday. Trades will remain breezy as a surface ridge holds to the north, and additional pockets of moisture will focus showers over windward and mauka areas, particularly during the overnight and early morning hours.

There remains a high chance of tropical cyclone gradually developing far southeast of the state within a few days. Most guidance tracks the main tropical cyclone feature well south of the islands over the weekend. GFS and ECMWF models show the northern flank of a broad pool of deep moisture grazing the windward Big Island and possibly reaching as far north as Maui County.

There remains about a 12 hour difference between the GFS and ECMWF models, with the GFS increasing showers as early as Friday morning and clearing the moisture Saturday. A tropical cyclone, or broad area of low pressure, passing south of the state could also lead to a period of stronger trade winds this weekend, as a ridge builds in from the northwest, as shown in the ECMWF runs. However, GFS shows only a minor fluctuations thus confidence is low at this time.

Fire Weather: Persistent rainfall will likely limited the widespread availability of receptive fuels. Breezy winds will continue during the next several days, generating moderate fire weather conditions. The inversion near Big Island will range from 6,000 to 8,000 feet over the next few days.

Marine Conditions…as of Wednesday afternoon: Fresh to strong trade winds will persist for most of the week across most coastal waters, as high pressure remains in place north of the region. Small Craft Advisory (SCA) conditions will likely persist across many waters throughout the week, due to a combination of winds and seas. Additionally this weekend, a tropical cyclone could pass far south of the state. According to National Hurricane Center, there is a high chance of tropical cyclone formation in the next 7-days.

Surf along north and west-facing shores will continue to decrease as the current small north-northwest swell fades and shifts more northerly. A more significant moderate, long- period northwest swell will arrive tonight into Thursday morning, and will easily push north and west shore surf to advisory levels for Thursday into Friday. An additional medium-period moderate swell is expected to fill in on Saturday, likely prolonging moderate to large surf action into the weekend.

A compact fetch of gales passing east of New Zealand last week Friday, should produce some waves slightly above average around this coming Friday into Saturday along south facing shores. East-facing shores will see continued moderate trade wind swell as strong trade winds remain. Surf along east- facing shores will stay elevated and choppy through much of the week with the strong trades.

Atlantic Ocean:
There are no active tropical cyclones

Western and Central Atlantic:

A non-tropical low pressure area is located a few hundred miles south of Bermuda. Environmental conditions could support this system gradually acquiring subtropical characteristics through this weekend while it moves slowly eastward over the western and central subtropical Atlantic. By early next week, environmental conditions are forecast to become unfavorable for further development.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 7 days…medium…50 percent 

 

Caribbean Sea: There are no active tropical cyclones:

Gulf of America: There are no active tropical cyclones

 

Northeast Pacific: There are no active tropical cyclones

>>> Eastern East Pacific:

A broad area of low pressure is producing a large area of disorganized showers and thunderstorms offshore of the coast of Central America. Gradual development of this system is possible during the next several days, and a tropical depression could form by this weekend while the low drifts northward. Regardless of development, this system could bring areas of heavy rain to portions of Central America through this weekend.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 7 days…medium…50 percent

 

Central North Pacific: There are no active tropical cyclones

>>>Well Southeast of the Hawaiian Islands:

Invest 95E

An area of low pressure located over the western portion of the East Pacific basin is starting to produce more concentrated shower and thunderstorm activity. Environmental conditions appear conducive for additional development of this system, and a tropical depression is likely to form over the Central Pacific basin during the next few days while it moves westward to west-northwestward at 10 to 15 mph.

* Formation chance through 48 hours…medium…60 percent
* Formation chance through 7 days…high…70 percent

Interesting: 
Climate Change is Making the Tropics Hotter

A new study finds that tropical areas often thought to be safe from the effects of climate change are actually experiencing significant changes in rainfall and extreme temperature events.

Researchers studied climate events at the La Selva research station in Costa Rica and the El Verde field station in Puerto Rico. They found that, while average temperatures were not changing much over time, the two locations did experience significantly more days of extreme heat in 2024 compared to long-term data stretching back to 1992.

“In La Selva prior to 2024, you had an average of eight hot days – days where the temperature exceeded the 95th percentile of temperatures at that site – per year,” said Alonso Ramirez, lead author of the study and a professor in the Department of Applied Ecology at North Carolina State University. “Now that number is up to 30. These spikes in temperature are becoming more severe and more common.”
