Hawaii’s Mountains – Here’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 Tuesday comments:  I’m home here in upper Kula, Maui, Hawaii.

The high cirrus clouds early this morning are still around…although a bit less than yesterday at the moment. These icy clouds lit up a gorgeous pink color at sunrise!

Mid-day, the high cirrus clouds are gone, and skies are sunny to partly sunny for the most part here in Maui County. The models continue to show increasing showers arriving tonight into Wednesday.

 Weather Wit of the day:  Clean Air Violation – A fragrant abuse of the law

 

Hawaii’s Broad Brush Weather Overview:  Moderate to locally breezy trade winds will persist into early next week, as high pressure holds far north of the state. Rainfall will be focused over windward slopes, though showers will be slightly enhanced and will periodically pass over leeward areas during the next several days.

Hawaii’s Weather Details:  Robust surface high pressure centered far northwest of Hawaii continues to drive locally breezy and gusty trade winds. A mid-level ridge is maintaining modest stability with an inversion, while broad and weak upper-level cyclonic flow is producing slight instability aloft.

Under these conditions, showers have been somewhat active, with many windward areas measuring up to 1/2″ of rain during the past 24 hours. The breezy trades have been carrying brief rainfall over leeward areas from Kauai to Maui, and spotty active showers have been falling over the heated South Kona slopes.

Breezy and somewhat wet trade wind weather will continue through into Friday, and slightly unstable conditions will persist, enhancing pockets of moisture traveling along the trade wind flow. The next such area of enhanced moisture will move in tonight and produce a boost in rainfall, especially over windward areas from Kauai to Maui. Expect brief, passing showers over leeward areas, except for South Kona, where spotty and briefly heavy showers will develop each afternoon.

A decrease in showers is expected during the weekend, as a ridge builds aloft and brings increased stability. Modest showers will likely become confined to windward slopes, and trade wind strength will chance little as surface high pressure passes north of the state.

Hawaii’s Marine Environment:  Fresh to strong easterly trades will persist through the weekend, as the surface ridge remains anchored north of the islands. A Small Craft Advisory will persist each day for the typical windier waters and channels around Maui County and the Big Island.

Surf along exposed north and west-facing shores will continue to increase to near-average levels as a medium-period northwest swell builds down the island chain. This swell will linger into the second half of the week, gradually shifting out of the north.

Surf along south-facing shores will remain below average through Thursday, as a background south swell fades. A fresh long-period south-southwest swell is expected to arrive over the weekend, bringing an upward trend with above-average surf. Forerunners should begin filling in Friday, with the swell peaking Saturday through Sunday. If it comes in larger than expected, surf could approach advisory levels this weekend.

Surf along east-facing shores will remain rough and choppy, with heights hovering around average each day.

Interesting:  Flood Risk Increasing in Pacific Northwest

The next great earthquake isn’t the only threat to the Pacific Northwest.

A powerful earthquake, combined with rising sea levels, could significantly increase flood risks in the Pacific Northwest, impacting thousands of residents and properties in northern California, Oregon, and Washington, according to new Virginia Tech research.

A study published this week in the Proceedings of the National Academy of Sciences found that a major earthquake could cause coastal land to sink up to 6.5 feet, expanding the federally designated 1 percent coastal floodplain, an area with a 1-in-100 chance of flooding each year, by 35 to 116 square miles.

“The expansion of the coastal floodplain following a Cascadia subduction zone earthquake has not been previously quantified, and the impacts to land use could significantly increase the timeline to recovery,” said researcher Tina Dura, lead author of the study and assistant professor of geosciences in the College of Science.
