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.

430 Thick wild fire smoke is making for an uncomfortable afternoon here in upper Kula! I have all my doors and windows closed tight, trying to keep the smoke out…the smoke does seem to be clearing slightly now at 510pm.

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:  Typical June weather will persist through the week, with locally breezy trade winds focusing showers over windward and mountain areas. Broad surface high pressure far north of the state will maintain trades near current strength through at least Wednesday, followed by a slight decrease in winds on Thursday. as the high shifts to the northeast.

A mid-level ridge overhead will maintain stable conditions, and little organized moisture is forecast to be moving along the trade wind flow. As a result, expect showers to be focused along windward areas, especially at night, with rainfall accumulations of less than a half of an inch per day at most sites.

Leeward areas will continue to be rather dry, except for scattered afternoon showers along the Kona slopes of the Big Island. Thin high cirrus clouds will pass over the islands into Monday, then dissipate as an upper-level low west of the state drifts away.

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 14

The post-tropical cyclone is moving toward the west-northwest near 9 mph. A gradual turn towards the west is expected tonight, followed by continued westward motion for another day or two. Maximum sustained winds have decreased to near 35 mph with higher gusts. Continued slow weakening is expected during the next couple of days. Dalila is forecast to dissipate late Tuesday or early Wednesday.

 

Offshore of Central America and Southern Mexico
Invest 94E

>>> A broad area of low pressure continues to produce disorganized showers and thunderstorms over and offshore of Central America. Environmental conditions appear conducive for gradual development of this system, and a tropical depression is likely to form in a couple of days while it moves west-northwestward near the coasts of El Salvador, Guatemala, and southeastern Mexico. Interests in these locations should monitor the progress of this system. Regardless of development, areas of heavy rain are likely across portions of Central America and southeastern Mexico during the next few days.

* Formation chance through 48 hours…high…70 percent
* Formation chance through 7 days…high…80 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.”
