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.

Glenn’s Sunday comments:  I’m at home here in upper Kula, Maui, Hawaii

It’s mostly clear with some clouds along the windward sides here in Maui County, with calm winds at my place, and with a chilly low of 49.5 degrees and the relative humidity is 79%

253pm, it’s another partly cloudy day here in paradise, with a sprinkling of clear and cloudy areas mixed in as well.

>>> Lowest Temperature Sunday, June 7, 2026 – 20 degrees near Kirk, OR

Hawaii’s Broad Brush Weather Overview…as of Sunday evening: Breezy trades will gradually weaken to moderate speeds by the latter half of the week. Periodic showers will filter in on the trade wind flow, mainly focusing over windward and mountain areas. By next weekend, the wind flow may become light enough to support land and sea breeze development.

Weather Details for the Hawaiian Islands…as of Sunday evening: Radar and visible satellite imagery show scattered showers moving into windward and mountain areas across the state. A surface ridge extending over the region from the northeast continues to supply very stable conditions across the state, with the upper air soundings at Lihue and Hilo showing strong inversions around 7,000 feet.

Based on the upstream cumulus clouds, brief isolated showers will continue to be ushered into windward and mountain areas under the inversion on the breezy trades, with an increase in shower coverage expected overnight into Monday morning. The surface ridge to the northeast of the state currently driving breezy trades across the area, which will weaken slightly as it sags south, then get pushed closer to the state through the week, as a series of lows move across the northern Pacific and a front approaches the region from the northwest. This will cause the trades to gradually ease through the week. Winds may become light enough by Friday to support land and sea breeze development, bringing afternoon clouds and showers to leeward and interior areas and partial clearing at night.

Marine Environmental Conditions…as of Sunday evening: Surface high pressure will remain anchored far northeast of the islands through early in the week. A Small Craft Advisory (SCA), remains in effect for the typical windy waters around Maui and the Big Island. By the middle of this week, a ridge north of the islands associated with the high will be weakened and depressed southward. As a result, trades will drop further and allow the SCA to be cancelled entirely Tuesday or Wednesday. As the ridge shifts further south, it will eventually end up near the Hawaiian Islands by Friday or Saturday, which will bring light and variable winds across the area towards the end of the week.

Small long-period forerunners of the next south swell continue to fill in, with energy centered in the 18 to 22 second bands along our nearshore buoys. Energy from this swell is expected to peak late Monday into Tuesday and bump up surf to slightly higher than the June average, but still below advisory criteria. Expect this swell to fade through mid-week. A smaller pulse of south-southwest swell is due late Thursday and Friday, and a more significant south-southwest swell is on track to arrive next weekend, likely bringing advisory level surf by late Sunday along south facing shores.

The combination of a large south-southwest swell coinciding with the peak monthly tides will lead to significant wave runup across areas of the shores, that typically remain dry during the afternoon high tide cycle from June 14th through around June 16th. Coastal flooding is also expected across low-lying coastal roadways, docks, boat ramps and other coastal infrastructure.

Small background energy from the west-northwest is possible over the next several days, from a former Typhoon in the West Pacific last week. Rough surf along east-facing shores will remain around seasonal average, then slowly decline through the mid-week, as trade winds ease. Surf will drop well below seasonal levels along east facing shores by the end of the week as the trades dissipate.

>>> Eastern Pacific: 

Post-Tropical Cyclone 01E (Amanda) – Last Advisory

AMANDA DEGENERATES TO A POST-TROPICAL REMNANT LOW

According to the NHC advisory number 22…Amanda is located about 1375 ESE of Hilo, Hawaii

The post-tropical cyclone is moving toward the west near 6 mph and this motion is generally expected to continue over the next several days. Maximum sustained winds have decreased to near 30 mph with higher gusts. The post-tropical remnant low of Amanda is forecast to dissipate by mid-week.

 

Tropical Cyclone 02E 

DEPRESSION DRIFTING TOWARD THE COAST OF GUERRERO MEXICO …FLOODING RAINFALL EXPECTED OVER PORTIONS OF SOUTHERN MEXICO THROUGH TONIGHT

According to the NHC advisory number 3A…Amanda is located about 95 south-southeast of Acapulco, Mexico

The depression is moving toward the northeast near 3 mph, and a turn toward the north is expected later today. On the forecast track, the center is forecast to reach the coast of Mexico within the warning area this afternoon. Maximum sustained winds are near 35 mph with higher gusts. Some strengthening is forecast, and the depression is expected to become a tropical storm before reaching the coast.

 

>>> Offshore of Central America:

Invest 92E

Showers and thunderstorms are starting to show signs of organization in association with a low pressure area offshore of Central America. Environmental conditions appear conducive for further development of this system, and a tropical depression is likely to form during the next day or two while the system moves slowly northward and then northwestward toward the coast of Central America. Interests along the Pacific coasts of northwestern Costa Rica, Nicaragua, Honduras, El Salvador, and Guatemala should monitor the progress of this system, as heavy rainfall and life-threatening flash flooding are possible through the middle portion of this week.

* Formation chance through 48 hours…high…90 percent
* Formation chance through 7 days…high…90 percent

Interesting:  Giant Fan-Shaped Geological Structure Discovered Beneath East Antarctica

An international team of researchers including our Department of Geography has discovered a vast geological structure hidden beneath the East Antarctic Ice Sheet.

Enormous Subglacial Basins

The structure is made up of a system of enormous subglacial basins buried in ice over three kilometers thick in parts.

Together, the basins form a giant fan-shaped structure on a continental scale. The team have named it the East Antarctic Fan-shaped Basin Province.

It includes some of Antarctica’s best-known subglacial features, such as the Wilkes and Aurora basins and the basin hosting Lake Vostok, the largest known subglacial lake on Earth.
