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.

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

855am, still mostly sunny, although the cumulus clouds are showing signs of gathering.

Late afternoon, and it’s a hot and very sunny day here on Maui…although there is a nice tropical breeze blowing, which is helping to moderate the heat a little.

Early evening has turned partly cloudy here in Maui County, and it’s become voggy as well. We have at least two layers of clouds as it gradually begins to get dark, the lower level cumulus clouds, and the higher level cirrus clouds. The cirrus lit up somewhat a subtle pink not long after sunset.

910pm, the temperature has dropped quickly to 59.3 degrees, although with the thick higher level clouds moving over the state, I doubt whether the temperature will drop too much tonight into early Wednesday morning.

Weather Wit of the day:  Draftsman – A person who hates to shut doors and windows

 

Hawaii’s Broad Brush Weather Overview:  Breezy and mostly dry trade wind weather will persist through Wednesday. Trade winds will gradually decrease Thursday into Friday, with a slight increase of shower coverage expected by Thursday. Light to moderate trade winds are expected over the weekend, with mostly dry conditions on Saturday and scattered showers Sunday.

Hawaii’s Weather Details:  Strong high pressure far northeast of the state will maintain breezy trade winds through Wednesday. Scattered showers will continue to ride in with the trade winds, and will mainly be focused over windward and mountain areas, with a few showers making their way to leeward areas as well, due to the breezy trades.

As the high weakens far northeast of the state, trade winds will gradually weaken Thursday into Friday, with moderate trade winds expected by Friday. A slight increase of shower coverage is possible Wednesday night into Thursday, but generally shower intensities will continue to remain light due to stable conditions in the lower levels.

In the mid to upper levels of the atmosphere, imagery is showing a weak upper level low located just west of the state. Very few impacts are expected from this upper level low, but some mid to high level clouds will stream over the state into Wednesday night and Thursday. The cloud cover forecast has been nudged up a touch, to show an increase of cloudiness on these days.

Over the weekend, mostly fair weather is expected with moderate trade winds. Saturday looks to be a mostly dry day with ample sunshine and a few isolated showers. Sunday should see an increase of shower coverage with some scattered showers expected. With the lighter trade wind pattern, we could see some localized sea breezes with afternoon clouds and showers over select leeward areas especially on Sunday.

Hawaii’s Marine Environment:  High pressure to the far northeast will remain nearly stationary and weaken over the second half of the week, resulting in moderate to locally strong trade winds slowly decreasing to gentle to locally fresh trades by Saturday. A Small Craft Advisory (SCA) has been scaled back to the windier waters and channels around Maui County and the Big Island through Wednesday.

Surf along south facing shores will remain small before a tiny to small long period southwest swell is expected to start filling in Wednesday. A larger event from a fetch near New Zealand is trending to bring a moderate long period south-southwest swell to start filling in on Friday, and peak Saturday potentially near High Surf Advisory (HSA) criteria.

Surf along north facing shores will remain small as the north-northwest swell lingers before declining tonight into Wednesday. East shore surf will remain choppy due to the moderate trade winds. A combination of a strong high pressure to the far northeast, and a low near California earlier this week, has produced the potential for a moderate medium period east swell to fill in Thursday, peak Friday, and decline through the weekend.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Offshore of the Southeastern U.S. Coast

>>>  Showers and thunderstorms located over the Florida peninsula, southeastern Georgia, the northwestern Bahamas, and the adjacent Atlantic and Gulf waters are associated with a broad trough of low pressure. A non-tropical low pressure area is forecast to form from this system near the southeastern U.S. coast during the next couple of days. If the low spends time offshore, it could gradually develop some subtropical or tropical characteristics late this week while moving northeastward at 10 to 15 mph. Regardless of development, periods of heavy rainfall are possible for coastal portions of the Carolina’s through Friday.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…low…10 percent

Caribbean Sea:  There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7-days.

Gulf of Mexico:  There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7-days.

Northeastern Pacific:   There are no active tropical cyclones

South of Southern Mexico

>>> An area of low pressure is forecast to form offshore of the coast of southern Mexico late this week. Environmental conditions are expected to be conducive for gradual development of this system, and a tropical depression will likely form over the weekend as it moves generally westward to west-northwestward around 10 mph.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…high…70 percent

North Central Pacific:  There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7-days.

Interesting:  2021’s Hurricane Ida Could Have Been Even Worse for NYC

During the final week of summer in 2021, Hurricane Ida emerged from the Gulf of Mexico, turned almost directly northeast and swept through the South en route to Pennsylvania, New York, New Jersey and Connecticut.

Fueled by unusually heavy rains, falling on ground still saturated by two other recent large storms, Ida would eventually carve a path of destruction through the region. Some New Jersey cities and towns received as many as nine inches of rain within a 24-hour period, overwhelming drainage capabilities; the metro region’s subways, train stations and tracks flooded for days, paralyzing mass transit.

All told, Ida would wreak an estimated $75 billion in total damages and be responsible for 112 fatalities — including 32 in New Jersey and 16 in New York state.

Yet the hurricane could have been even worse in the Big Apple.
