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 it’s mostly clear to partly cloudy, with calm winds at my place, and with a low temperature of 55 degrees and the relative humidity is 88%

1025am, cloudy and we just had our first light shower of the day here at my place.

1127am, still lightly showering with relatively cool temperatures…while the relative humidity here in upper Kula 82%

1256pm, still lightly showering, a total cloudy day from my point of view, which seems more like a winter day than a very late spring day.

251pm, the clouds and showers briefly tried to back off, although I just turned around from my desk here in the weather tower, and found dense fog with more showers falling again.

508pm, very cool, cloudy and wet here in upcountry Maui, like I was saying above…a winter-like day here in paradise!

618pm, it’s still wet here in upper Kula, although as we head towards sunset, I can see some sunshine down towards Kihei.

Hawaii’s Broad Brush Weather Overview…as of Sunday evening: Surface high pressure continues to strengthen northeast of the state tonight, and will bring an increase in trade wind flow. Low clouds and showers will remain through Monday morning mainly over portions of Maui, Molokai, and Oahu, as an area of enhanced moisture moves in from the east.

From late Monday through Friday, light easterly winds will return. Afternoon coastal sea breezes should help bring clouds and showers to interior and mountainous locations. From Wednesday onward, deeper moisture moving in from the southeast should bring increased precipitation chances to the Big Island, and perhaps Maui.

Weather Details for the Hawaiian Islands…as of Sunday evening: Showers continue, mainly over Maui County and Oahu, with only isolated activity on the Big Island and Kauai County. Skies were mostly cloudy except over Kauai County and much of eastern Big Island. Minimal volcanic ash has been observed with today`s 39th episode of Kilauea, and most of it has been carried southwest of the crater into relatively uninhabited areas. Winds have become light and variable, allowing the ash to fall out close to the crater, with some light northeast drift.

Trades averaging 10 to 20 mph will continue through Monday, then weaken to 5 to 10 mph from Tuesday to the end of the week, as the surface pressure gradient slackens again. Rainfall will be light for most areas, but increased moisture will make it to the Big Island from Wednesday into next weekend. This moisture may briefly extend north and west toward Maui County (and perhaps even Oahu) Thursday and Friday, increasing the chance of showers there.

This moisture will be associated with an increase in the height of the trade inversion, which makes for slightly deeper and stronger showers. But significant heavy rain is not forecast. The light winds for most of the week means a return to sea breeze showers over leeward areas, along with some weak windward and mountain enhancement.

Marine Environmental Conditions…as of Sunday evening: A long-period south-southwest (200 degree) swell will continue to fill in today and peak tonight into Monday before gradually declining through the rest of the week. Buoy 51002, south of the islands, is observing around a 4 foot swell at 19 seconds this morning, with a peak observation exceeding 5 feet. As a result, surf heights along exposed south facing shores are forecast to hover near high- end advisory levels today, while west-facing shores see moderate surf. There is potential that as the swell reaches its peak tonight that surf could reach warning levels, along with advisory level surf for west facing shores. South shore surf will remain elevated through much of next week due to the slow decline of this large south swell and a series of continued overlapping southerly swells.

This swell will also coincide with the peak monthly tides which will add the potential for significant wave runup on top of minor coastal flooding potential during the monthly peak tides through the first half of next week. Once the peak swell passes, south shore surf will remain elevated through much of the week due to the slow decline of this large south swell and a series of continued overlapping southerly swells.

Very little swell energy is arriving along north facing shores, keeping surf tiny to flat. A small bump in surf is possible for north- facing shores on Tuesday with the arrival of a small northwest swell and a smaller north swell. Gentle to moderate east-northeasterly winds expected through next week will keep surf along east facing shores below seasonal average.

A Coastal Flood Statement remains in effect for minor coastal flooding of vulnerable low-lying coastal roadways, docks, boat ramps and other coastal infrastructure. King Tides combined with water levels that are running higher than predicted will lead to minor flooding potential around the daily peak tide, which will be during the late afternoon and early evening hours, through at least Tuesday. While minor coastal flooding is expected along all shorelines, the combination of the south-southwest swell, King Tides and the daily high tide will make low-lying coastal areas along south and west shores susceptible to more widespread coastal flooding through the first half of next week.

World-wide Tropical Cyclone Activity


>>> Here’s a link to the latest Pacific Disaster Center’s Weather Wall


>>> Atlantic Ocean: There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7 days.

>>> Caribbean Sea: There are no active tropical cyclones

 

>>> Gulf of America: There are no active tropical cyclones

Northwestern Gulf of America: 

A trough of low pressure located over northeastern Mexico continues to produce disorganized shower and thunderstorm activity. Development is not expected during the next day or so while the trough remains inland and drifts generally northward over northeastern Mexico and southern Texas. The system is then forecast to move northeastward and could re-emerge over the northwestern Gulf of America late Tuesday or Wednesday, where environmental conditions may support some development around midweek. Regardless of tropical cyclone formation, heavy rainfall and flash flooding are possible across portions of eastern and southern Texas and Louisiana this week.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…low…30 percent

>>> Northeast Pacific: There are no active tropical cyclone

Well Southwest of the Baja California Peninsula:

Invest 93E

A broad area of low pressure located well southwest of the Baja California Peninsula is producing disorganized showers and thunderstorms. Environmental conditions could support some gradual development during the next day or so while the system moves northward and then northwestward at 5 to 10 mph. Thereafter, increasing dry mid-level air is expected to limit further development.

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

Tropical cyclone formation is not expected during the next 7 days.

Interesting: U-M Researchers Help Ocean Observations Snap into Focus

University of Michigan researchers have used a U.S. Navy ocean forecasting model to predict where internal tides occur in the ocean in order to bring ocean patterns important to weather forecasting and shipping into clearer focus.

In particular, scientists are interested in observing ocean patterns called small-scale oceanic eddies—small swirls of water that break off larger eddies created by the Gulf Stream—because they are instrumental in transporting heat and carbon in the ocean. Understanding them can also help the Navy predict weather forecast models for fleet operations, according to U-M oceanographer Brian Arbic.

In 2022, NASA and the French space agency CNES launched a satellite called SWOT, or the Surface Water and Ocean Topography mission, with the primary goal of observing small-scale eddies. SWOT can track ocean water movements on a minute scale, on the order of 5-to-10 kilometers rather than around 100 kilometers. However, internal tides—water that moves vertically up and down an ocean column—can mask images of the eddies observed by the satellite.
