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. I hope you have a good Tuesday wherever you happen to be spending it.

It’s clear, with a low temperature of 50.5 degrees degrees according to my outside temperature sensor.

The afternoon clouds here in upper Kula have set in, and  it looks like they are extending down towards the coasts locally. The winds remain light, and the temperature is hovering right around 70 degrees or so at 109pm.

 

Hawaii’s Broad Brush Weather Overview:  Dry and stable conditions will persist state-wide through Wednesday, with a deep-layer ridge remaining in place over much of the region. This will result in a land and sea breeze regime, with afternoon clouds and a potentially a few brief showers over interior and leeward areas.

An approaching cold front could result in a slightly better chance of showers over Kauai and Oahu on Thursday, with dry weather continuing elsewhere. Another cold front will approach and potentially reach the islands by early next week.

Hawaii’s Weather Details:  Dry and stable conditions, with a deep-layer ridge in place over much of the area, are expected through mid-week. The surface ridge has shifted southward over the islands in response to a progressive pattern over the northern Pacific, featuring a series of fronts passing nearby to the north.

Light southerly low-level flow around the ridge axis will shift out of the southwest over the western end of the state beginning later today. This will support the land and sea breeze pattern continuing, with the best chance for cloud coverage developing over interior and leeward locations during the afternoon hours. While a few brief afternoon showers can’t be ruled out in these areas, accumulations will be minimal due to the dry environment.

For the second half of the week, there’s an increasing likelihood of increasing low-level moisture and rain chances. This is due to the tail-end of one of the aforementioned cold fronts settling south into the islands, from Wednesday night through Thursday. Guidance supports this, showing the best chances for some light accumulations along northern and windward slopes, with northerly winds filling in. The progressive pattern will persist into the weekend, with another front approaching and potentially reaching the islands late Sunday into early next week.

Fire weather:  Critical fire weather conditions are not anticipated through the week, due to a combination of light winds and increasing moisture later in the week as a cold front settles southward into the area.

Hawaii’s Marine Environment:  The high pressure ridge north of the state will remain over the islands through the weekend. This pattern shift will keep a fairly light and variable wind pattern for most days this week. A weakening cold front will drift over the area on Thursday, bringing gentle to locally moderate cool northerly winds. As the front and high dissipate Friday, the surface ridge will move over the islands, with light and variable winds returning into the weekend.

The strong lows passing north of the area will have significant wind fetches aimed toward the islands. Although their fast-moving nature limits the ability of these powerful (up to hurricane force at times) lows to generate fully developed seas, there will still be several bouts of large to extra-large surf along north and west facing shores through the weekend. Given recent wave model guidance under predicting the peak heights of northwest swells, especially with hurricane-force lows, the latest official forecast incorporates a swell height bias of 1-3 feet larger than model guidance.

Small surf remains in the short term forecast as we wait for the offshore buoys to respond to the next large NNW swell. Observations from buoy 51001 shows very small forerunners arriving, that are running a little bit below wave model swell heights. However, forecasts show increasing swell energy from the NNW to move into the islands, bringing a modest increase in surf heights for north and west facing shores.

Surf heights will then rise more significantly starting later tonight through Friday, necessitating a High Surf Warning for exposed shores during its peak on Thursday and Friday. Another extra large NNW swell is anticipated to arrive in Hawaiian waters by this weekend. Combined seas will require a Small Craft Advisory for many waters into the weekend.

Small surf remains in the forecast for south and east facing shores. East shore surf will stay small through the week, as trade winds are disrupted, aside from some swell energy wrap from larger northwest swells Wednesday through the weekend. Surf along south facing shores will remain seasonally small, mainly due to background swells.

Interesting:  Exposure to Remote Wildfire Smoke Drifting Across the U.S. Linked to Increased Medical Visits for Heart and Lung Problems

Wildfire smoke has long been known to exacerbate health problems like heart disease, lung conditions, and asthma, but now a new study finds that smoke from these fires can lead to poor health thousands of miles away. Researchers from the University of Maryland Institute for Health Computing (UM-IHC) found that medical visits for heart and lung problems rose by nearly 20 percent during six days in June, 2023, when smoke from Western Canadian wildfires drifted across the country, leading to very poor air quality days in Baltimore and the surrounding region.

The new findings were published in the journal JAMA Network Open.

During the summer of 2023, severe Canadian wildfires created a vast plume that drifted more than 2,000 miles across the country, leading to poor air quality on the East Coast of the United States, and many individuals experiencing breathing issues that led them to the doctor’s office.
