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 evening: Breezy trade winds will persist through the next several days as high pressure holds north of the state. Pockets of moisture moving through with the trades will focus rainfall over windward and mauka areas, with showers briefly passing over leeward areas. A tropical disturbance well to the south will enhance showers on windward Big Island, Maui, and perhaps as far north as Oahu Friday into Saturday.

Weather Narrative…as of Wednesday evening: After numerous showers in windward, mauka, and some leeward areas of the smaller islands earlier, coverage has decreased and are focused mostly in windward areas. Little change is expected tonight through at least Thursday. A ridge of high pressure north of the state is driving breezy trades across the island chain, which will continue. Additional pockets of moisture will focus showers over windward and mauka areas, particularly during the overnight and early morning hours.

An area of showers and thunderstorms is gradually becoming better organized well southeast of the state. There remains a high chance (70 percent) of this activity gradually developing into a tropical cyclone within a few days. The ridge to our north will steer this system westward and keep direct impacts well to the south. However, a rich plume of moisture will pass through southern parts of the state. The last several model runs have shown a consistent trend with bringing this deep moisture farther north. What looked like the Big Island being grazed with this moisture 24 hours ago, now looks like at least the Big Island and Maui, perhaps as far north as Oahu.

In addition, with surface high pressure settling southeast toward the state, while the potential tropical system passes to the south, trades may strengthen further Friday into Saturday. Timing consistency is improving between the GFS and the ECMWF models, with the deep moisture arriving by late Friday morning and exiting to the west sometime Saturday morning. Some of these showers may spill into leeward areas as well. Locally heavy rainfall will be possible.

After the passage of that system, much drier air and lower inversion heights will filter in from the east-northeast Sunday into next week. Shower coverage will decrease, but a few may remain possible in windward locations each day.

Fire Weather: Persistent rainfall will likely limit 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 evening: Fresh to locally strong trade winds with responding high seas will persist the next several days. This is a result of a tight north to south pressure gradient across the waters from higher pressure north of the state, in relation to lower equatorial pressure. Due to this combination of strong trades and responding elevated seas, a Small Craft Advisory remains in effect for all marine zones for the foreseeable future.

An area of disturbed weather far southeast of the islands is being monitored for the high likelihood of tropical cyclone development. This disturbance, or whatever it evolves into, will travel south of the Hawaiian Islands through early next week. A moderate size, long period northwest swell will begin arriving early Thursday morning and will likely be detected at the far northwest offshore buoys tonight. As this swell fills in around the island chain, it will increase north and west- facing shore surf heights to advisory levels. A High Surf Advisory will be in effect from 6am Thursday morning through 6am Friday morning for the smaller islands. A reinforcing moderate size, medium period northwest swell will arrive Saturday and likely prolong elevated moderate size north and west surf through the weekend.

A compact fetch of gales passing east of New Zealand late last week created a swell that should reach the local waters in a couple of days. This very slight bump in south-southwest swell may produce near to slightly above average south-facing shore surf this weekend. Moderate to strong trade winds will ensure rough and choppy conditions along east-facing shores well into next week.

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…medium…40 percent
* Formation chance through 7 days…medium…60 percent

 

Central North Pacific: There are no active tropical cyclones

>>>Well Southeast of the Hawaiian Islands:

Invest 95E

Showers and thunderstorms associated with a trough of low pressure located over the eastern portion of the Central Pacific basin are gradually becoming better organized. 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

Tropical Cyclone 30W (In-Fa)…is located approximately 131 NM west-northwest of Chichi Jima

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.”
