Glenn’s Friday comments:  I’m at home here in upper Kula, Maui, Hawaii

516am, it’s mostly clear here in upper Kula with calm winds, and a low temperature at my place of 53 degrees…with the relative humidity 80%

430pm, partly sunny, yet another nice summer day here in the islands.

817pm, partial clearing of the afternoon clouds, with the temperature here at my weather tower 63.8 degrees, with the relative humidity 75%

 

>>> Interesting weather web blog: Mauka Showers…Hurricane Fausto Heading Towards the Hawaiian Islands

 

We have Hurricane Fausto continuing to churn the waters of the eastern Pacific, far to the east of the Hawaiian Islands. It will continue more or less westward over the next several days. It will cross over into our central Pacific Saturday. From there it may eventually get close to Hawaii, or move by not far to the north. If this were to occur, we could see the associated cloud field bring showers and wind our way around Tuesday/Wednesday of next week. Additionally, we should see rising surf this weekend along the east facing shores…generated by Fausto. As we know, things may change going forward, so that I’ll keep abreast of these changes and make updates here as warranted.

Hawaii’s Weather Highlights…as of Friday evening: A strong high pressure system far north of the Hawaiian Islands will continue to produce moderate to breezy trade winds through Monday, with periods of showers favoring windward mountain areas, in the overnight to early morning hours.

Hurricane Fausto remains on track near the Hawaiian Islands early next week. The latest forecast for Fausto shows a weakening trend to tropical storm strength as it moves closer to the island chain. The trade wind weather pattern will return from Thursday night onward, as Fausto drifts westward away from the Hawaiian Islands.

Short Term Update: A strong high pressure ridge remains locked in place north of the Hawaiian Islands, keeping easterly trade winds in the forecast through the end of next week. One exception to this trade wind weather pattern will develop early next week, as Hurricane Fausto continues to track into the Hawaii region. Subtle shifts in the storms track or intensity will lead to forecast changes in island by island weather impacts.

Potential Fausto Impacts Include…High surf above advisory thresholds along east facing shores is likely from late Sunday through Tuesday, strong winds may occur near the center of the low, and heavy rain threats are possible as Fausto moves into our area from Tuesday through Wednesday. No time like the present to review your family hurricane preparedness plans, and ensure every household has at least a 14 day supply of food and water available if needed during this years active hurricane season.

Weather Commentary…as of Friday evening: Breezy trade winds will usher in windward clouds and showers through Monday. Incoming clouds and showers will focus over windward and mountain areas, mostly occurring during the nighttime and early morning hours. Atmospheric soundings show a stable environment across the islands, with an inversion around 7,000 feet.

The main event next week will be the approach of now Hurricane Fausto. Fausto is expected to weaken over the next several days as it tracks west across higher wind shear and cooler waters, reaching the vicinity of the Hawaiian Islands on Tuesday. Main impacts Tuesday and Wednesday include winds, rain and east shores surf, and will be dependent upon Fausto`s eventual path.

Mitigating effects will be Fausto`s quick 15 mph westward movement, limiting how long it will rain across the same areas. Winds could also be mitigated on a more northerly swing of the track, but more impactful if it slides southward. Still lots of possibilities, so best to look at preparations this weekend, and stay tuned for updates to the forecast and any issuance of watches and warnings. Trades will fill in Thursday night in the wake of Fausto, and continue into next weekend.

Marine Conditions…as of Friday evening: Robust high pressure far north of the state continues to produce fresh to strong trade winds, but winds drop down a notch tonight. The Small Craft Advisory (SCA) has been trimmed back to just the typically windy waters around Big Island and Maui County due to slight easing of the trades as the high drifts westward. Trades may decline slightly Sunday into Monday, but wind trends become less clear Tuesday due to uncertainty in the eventual track and strength of Hurricane Fausto.

Generally speaking, expect winds to veer northeast and strengthen ahead of the cyclone, while winds will actually diminish somewhat south of the storm at a distance from the center. This appears more favored for an area south of the islands. The current National Hurricane Center forecast calls for Fausto to be a tropical storm by Monday with continued weakening as it passes near the islands Tuesday and Wednesday.

The current south-southwest swell continues to produce advisory level surf this afternoon. With a slow decline expected through at least the first part of the night, the High Surf Advisory has been extended through Saturday. Surf along south facing shores may briefly dip below advisory thresholds late tonight or early Saturday, but this will be followed by another pulse of swell that will likely push surf above the advisory level for Saturday and Sunday. The south-southwest swell will then slowly decline early next week, with a smaller south- southwest swell possible during the middle of the week.

Rough east shore surf will remain a notch above seasonal average into Saturday as a result of fresh to strong trade winds. Long-period swell from Hurricane Fausto arrives tonight into Saturday and builds through early next week. The Fausto swell will likely produce advisory- level surf along east facing shores by Sunday or Monday, with the largest surf expected Tuesday or Wednesday depending on the eventual track of the tropical cyclone.

Surf along north-facing shores will remain at flat to tiny levels through the weekend. Some increase is expected as Fausto or its remnants pass over the area Tuesday and Wednesday.

>>> Well Southwest of Hawaii:

An area of low pressure located well southwest of the Hawaiian Islands is producing disorganized showers and thunderstorms. Environmental conditions appear conducive for some gradual development of this system while it moves slowly westward to west-northwestward, and a tropical depression is likely to form after it enters the western Pacific basin over the weekend or early next week.

Interesting:  Antarctica Is Giving Us a Warning of Sea Level Rise Decades in Advance – Now Is Our Time to Act

Scientists predict that the next three to five decades provide a critical window to anticipate and plan for Antarctic ice loss and its contribution to sea level rise.

Research published in Nature, led by Monash University researcher Dr Felicity McCormack from Securing Antarctica’s Environmental Future (SAEF), looks at the predictability of Antarctic ice loss and what this means for sea level rise projections.

Based on reports from the Intergovernmental Panel on Climate Change (IPCC), a global sea level rise exceeding two metres by 2100 cannot be ruled out under high-emission scenarios due to the large-scale collapse of the Antarctic Ice Sheet.

This level of sea level rise would expose one quarter of Australian residential properties to inundation, render much sovereign territory across the Pacific uninhabitable, and displace hundreds of millions of people globally, representing one of the most significant humanitarian and economic challenges in history.
