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 Wednesday comments:  My good friend Bob Earle and I are here at Sea Ranch, CA.

It’s cloudy this morning here at the coast. The low temperature was 53 degrees.

Cloudy with light showers and increasing winds. We have a potent storm system taking aim on the coast of California, from Eureka all the way down to San Diego! Bob and I are hunkered in just enjoying the squalls as they roll into the coast on gusty winds. This doesn’t keep the sea gulls, pelicans, and the rest of the shore birds from flying by, as we watch the show through the picture windows and sliding glass doors.

Wow, 73mph gust a Puuloa down on the Big Island, and a 65mph gust at Na Kula on Maui during the afternoon Wednesday!!

Hawaii’s Broad Brush Weather Overview: A broad high dominating much of the Central Pacific will maintain breezy to windy trades across the Hawaiian Islands through Thursday morning. Enhanced shower activity and cloud coverage will persist predominately over windward and mountain areas. Trades will begin to weaken to a more moderate level by Friday, in response to the high weakening and propagating northeastward away from the Hawaiian Islands.

Hawaii’s Weather Details:  The latest surface analysis shows a broad 1035 millibar area of high pressure far north of the Hawaiian Islands. This is keeping breezy to windy trades blowing across the islands, so the current Wind Advisory for portions of Maui County and the Big Island remains in effect through 600am Thursday morning. Surface observations show widespread wind speeds greater than 30 mph, with the strongest winds blowing across the Kohala District of the Big Island.

Guidance continues to show the strongest winds continuing tonight, with some of the models suggesting advisory winds may continue across portions of the Big Island through the day Thursday. Look for the winds to slowly weaken on Thursday and become moderate to breezy by Friday, as the area of high pressure meanders northeastward away from the state.

Meanwhile, radar and satellite continue to show enhanced showers moving into windward and mountains areas, with some of the more robust showers producing over 0.50 inches of rain over the last 6 to 12 hours. Expect additional areas of moisture embedded in the trades upstream of the islands. This will keep windward and mountain showers going through the week, with a few showers likely spilling over into leeward areas during the overnight and early morning hours. Showers look to gradually taper off over the weekend, as a drier and more stable air mass briefly moves into the area.

Confidence in the forecast lowers as we head into next week. Some model guidance continues to show a surface trough producing southerly flow over the islands, escorting an abundance of moisture from the tropics with it around Monday or Tuesday of next week. If the GFS solution pans out, we could see ample tropical moisture being pulled northward into the islands, which could lead to a period of moderate to heavy rain next week.

However, if the ECMWF model solution wins, most of the tropical moisture will remain south of the islands and the heavy rain threat would be lower. The one thing both models now have in common is the depiction of a cold front advancing south towards the islands early next week. We’ll need to monitor trends over the next several days, to see how the synoptic pattern evolves before we can determine what, if any, threats there are for the Hawaiian Islands early next week.

Fire weather:  Critical fire weather conditions are not expected. Breezy to windy trades will continue through Thursday morning, becoming moderate to breezy before the weekend. However, low-level moisture embedded in the trades should help to keep relative humidity from reaching critical thresholds.

Hawaii’s Marine Environment:  A strong 1034 millibar surface high, centered well north of the islands, will help drive fresh to locally gale force trade winds across Hawaiian waters. The high will slowly drift slowly southeast through tonight and maintain robust east northeasterly flow. The strong trade winds, combined with building northeast and northwest swells, will also result in high seas across the area. A Gale Warning remains in effect through Thursday morning for the Alenuihaha Channel, where flow funneling around the terrain of Maui and the Big Island will accelerate trades even more. Elsewhere, a Small Craft Advisory (SCA) remains in effect for a combination of winds and seas. The aforementioned high to our north will gradually drift eastward and weaken Friday into this weekend, allowing winds to weaken to moderate to locally strong through the weekend.

The current short period northeasterly swell will produce large breaking waves along east facing shores through Thursday afternoon. A combination of higher than predicted water levels, large breaking waves, and strong onshore winds could lead to significant wave runup, beach erosion, and localized coastal flooding for east facing shores during daily peak high tide cycle. Thus, a High Surf Advisory remains in effect for east facing shores through 6am Thursday. Northeast swell energy and associated surf should decline late Thursday through this weekend, as local trade winds weaken.

A small to moderate, long period, northwest swell will peak and keep surf along north and some west facing shores elevated, but below advisory levels. This swell energy should fade through Friday. Another small, long period, northwest swell is forecast to enter the local waters this weekend, which will again bring a sub-advisory level rise in surf along north facing beaches.

A small, long period, south swell will peak and generate surf near or slightly above the November average, then fade through the remainder of the week.

Interesting:  Climate Change Expands Wildfire Danger Worldwide: New Study Warns of Unprecedented Risks in the Coming Decades

A new study, led by CMCC and Coventry University, reveals that climate change will dramatically expand wildfire danger across the globe, with up to 91% of fire-prone regions experiencing heightened risk by the end of this century.

However, these changes are not just limited to areas that are traditionally fire-prone but could also affect ones that have rarely experienced wildfire risk in the past.

“Wildfire danger is expanding and intensifying due to climate change,” says CMCC researcher and co-author of the study Maria Vincenza Chiriacò. “The key takeaway from this study is that climate-driven fire danger is not a distant or localized issue, but a growing global challenge that demands proactive action.”

Some of the most pronounced increases in fire danger are expected in regions such as southern Africa, the Mediterranean region, northern Asia, northeastern South America, and parts of North America.
