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 Sunday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s clear to partly cloudy here in Maui County this morning. The low temperature here at my place was 51 degrees.

1107am, there’s a bunch of beautiful Cirrus cloud streaks across the skies of Maui County.

120pm, there’s a large brush fire up the mountain from here in upper Kula, which is making our area smokey.

Happy Father’s Day to all you Dad’s out there, and especially to my own, Mr. Edward Eugene James!

Hawaii’s Broad Brush Weather Overview:  Breezy trades will generally focus clouds and showers over windward and mountain areas through the week, especially at night and during the early morning hours.

Hawaii’s Weather Details:  A fairly typical breezy trade wind pattern can be expected through the upcoming week, with only minor fluctuations in wind speeds and rain chances expected.

Surface high pressure to the north and northeast of the state will maintain breezy trades through at least Tuesday. Model guidance indicates that the local pressure gradient may fluctuate some mid-week as the two areas of high pressure merge into one and build to the far northeast of the state, leading to some variation in trade wind speeds…but generally speaking, breezy conditions can be expected through the week.

Aloft, a weak upper level low will remain just west of Kauai, possibly leading to a slight increase in windward and mountain showers for that end of the state. However, these showers are expected to be light, as the strong temperature inversion prevents any substantial vertical development. Mid level ridging will build over the state as the aforementioned upper low retreats northwestward Monday, maintaining stable conditions through the rest of the week.

In this stable, breezy trade wind pattern, showers will favor windward and mountain areas overnight, along with the Kona slopes of the Big Island each afternoon, as pockets of low level moisture filter in on the trade winds.

Hawaii’s Marine Environment:  High pressure north will continue to produce fresh to locally strong trade winds throughout the next week. A Small Craft Advisory (SCA) for the windier waters and channels near Maui and the Big Island was extended in time through Monday night, and this advisory will likely continue for these windier waters through much of the week.

A series of small, long-period, south swells will help boost surf heights along south facing shores though the week. The first of these swells will fill in now through Monday, followed by another round from Wednesday into Thursday.

Rough and choppy surf along east facing shores will continue. Surf will remain nearly flat along north facing shores throughout the forecast period.

According to the NHC Advisory number 13

Dalila is moving toward the west-northwest near 8 mph. A gradual turn towards the west will occur later today, with a continued westward motion the next couple of days. Maximum sustained winds have decreased to near 45 mph with higher gusts. Steady weakening is forecast the during the next couple of days, and the system is expected to become a remnant low later tonight. Tropical-storm-force winds extend outward up to 90 miles from the center.

 

Offshore of Central America and Southern Mexico
Invest 94E

>>> A broad area of low pressure continues to produce disorganized showers and thunderstorms offshore Central America. Environmental conditions are expected to be conducive for gradual development of this system, and a tropical depression is likely to form by the middle of this week while moving westward to west-northwestward just offshore of the coasts of El Salvador, Guatemala, and southeastern Mexico.

* Formation chance through 48 hours…medium…40 percent
* Formation chance through 7 days…high…70 percent

Interesting:  Wet Soils Increase Flooding During Atmospheric River Storms

A new study examined decades of atmospheric river storms across the West Coast to pinpoint the conditions that lead to catastrophic flooding.

Atmospheric rivers are responsible for most flooding on the West Coast of the U.S., but also bring much needed moisture to the region. The size of these storms doesn’t always translate to flood risk, however, as other factors on the ground play important roles. Now, a new study helps untangle the other drivers of flooding to help communities and water managers better prepare.

The research, published June 4 in the Journal of Hydrometeorology, analyzed more than 43,000 atmospheric river storms across 122 watersheds on the West Coast between 1980 and 2023. The researchers found that one of the primary driving forces of flooding is wet soils that can’t absorb more water when a storm hits. They showed that flood peaks were 2-4.5 times higher, on average, when soils were already wet. These findings can help explain why some atmospheric river storms cause catastrophic flooding while others of comparable intensity do not. Even weaker storms can generate major floods if their precipitation meets a saturated Earth, while stronger storms may bring needed moisture to a parched landscape without causing flooding.

“The main finding comes down to the fact that flooding from any event, but specifically from atmospheric river storms, is a function not only of the storm size and magnitude, but also what’s happening on the land surface,” said Mariana Webb, lead author of the study who is completing her Ph.D. at DRI and the University of Nevada, Reno. “This work demonstrates the key role that pre-event soil moisture can have in moderating flood events. Interestingly, flood magnitudes don’t increase linearly as soil moisture increases, there’s this critical threshold of soil moisture wetness above which you start to see much larger flows.”
