Hawaii’s MountainsHere’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 Weather Narrative ~~~

 

Glenn’s Thursday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s clear here in upper Kula early this morning, while my low temperature was a chilly 47.5 degrees.

I played Pickleball in Makawao this morning, although it was crowded so I only got to play 3 or 4 games.

Apparently this evening’s total lunar eclipse begins at 826pm, and lasts for 66 minutes here in the islands.

I saw the Lunar eclipse, at least off and on, as the clouds came and went…it was very cool!

840pm, the temperature has dropped to 61.3 degrees after a high of 78.5 degrees here at my place.

Weather Wit of the day:  Weather Satellite – A pry in the sky

 

Hawaii’s Broad Brush Weather Overview:  Gusty trade winds will gradually decline on Friday, as high pressure to the northeast slowly weakens. Rainfall will remain focused on windward areas, with some afternoon showers developing across leeward Big island slopes.

East to southeast trade winds will be light enough for afternoon sea breezes and spotty showers to develop over all leeward areas Saturday into early next week, and a low pressure disturbance aloft will bring some instability, resulting in some briefly heavy localized showers.

Hawaii’s Weather Details:  Mostly dry and stable conditions will persist for most areas through Friday, as a strong low- to mid-level ridge remains anchored north of the islands. This setup will maintain breezy to windy trade winds, though slightly weaker than in recent days. Brief showers will favor windward and mountain areas, primarily overnight and into the morning hours, as shallow pockets of moisture move through beneath a strong subsidence inversion.

The exception has been over windward sections of the Big Island overnight, where a persistent band of low-level moisture is supporting scattered to numerous showers (rainfall rates up to a quarter of an inch per hour). A weak mid- to upper-level trough moving over the eastern end of the state later tonight through Friday will lead to the weak and elevated inversion lingering, with the rainfall chances remaining up.

A transition period is expected over the weekend as a weakness develops in the ridge to the north in response to an approaching upper trough, that will eventually close off northwest of the state. The low-level flow will respond by weakening and shifting out of the east-southeast. Model guidance remains in decent agreement, indicating this pattern will persist through early next week, with upper heights gradually lowering as the upper low drifts eastward toward the area.

As the mean low- to mid-level wind flow remains steady out of the southeast direction, moisture will be drawn northward into the island chain. This added moisture, combined with increasing instability, will support higher rainfall chances statewide, with showers favoring windward and mountain areas overnight and into the morning hours, then shifting to leeward locations each afternoon where sea breezes develop.

Hawaii’s Marine Environment:  Strong high pressure north of the Hawaiian Islands will drift slowly eastward this week, allowing strong winds to decrease in strength from Friday on into the weekend. The Small Craft Advisory was extended in time for most for Coastal Waters through Friday afternoon, due to strong trades and elevated seas.

A trough of low pressure will approach the islands from the northwest into Friday, causing the trade winds to slowly decrease and veer from the east to southeast direction by Friday. Moderate to fresh east to east-southeast winds will likely persist into early next week.

The current moderate size, medium to long period north northwest (330 degree) swell has reached its peak, and will decline. A similar sized west-northwest (300-320 degree) swell will move into the area tonight and peak by Friday near High Surf Advisory levels. The next northwest (310-320 degree) swell will arrive by next Tuesday and boost surf heights along north and west facing shores to just below advisory thresholds late Tuesday into Wednesday.

Surf along east facing shores will remain rough and choppy just below advisory thresholds, due to strong trade winds over and upstream of the islands through Friday,                                                                                                                                                                                                                before declining into the weekend as trade winds decrease.

Interesting:  In This Storied Egyptian City, Rising Seas are Causing Buildings to Crumble

As waters rise along the Egyptian coast, hundreds of buildings in the historic port city of Alexandria have collapsed.

“For centuries, Alexandria’s structures stood as marvels of resilient engineering, enduring earthquakes, storm surges, tsunamis, and more,” said Sara Fouad, of the Technical University of Munich. “But now, rising seas and intensifying storms — fueled by climate change — are undoing in decades what took millennia of human ingenuity to create.”

Fouad is the lead author of a new study investigating why, over the past two decades, the number of buildings collapsing each year in Alexandria has risen tenfold. For the research, scientists compared present-day satellite imagery with decades-old maps to track the retreat of Alexandria’s shoreline, inferring where rising seas had intruded into groundwater. Researchers also mapped which buildings had collapsed and studied soils for evidence of intrusion.
