Glenn’s Saturday comments: 

Good day everyone, I hope you have a great Saturday wherever you happen to be spending it.

I’m here in Bend, Oregon, and will be here until Monday, visiting my friend Bob. So, I’ll be sharing what’s going on here in the high desert of eastern Oregon. The high temperature today here in Bend (Saturday) is forecast to be 88 degrees…along with an air quality alert for smoke.

623am, Bob and I are heading out to get a cup of joe at the Commons (in downtown Bend), and then driving over for a long walk along the Aspen lined Deschutes River.

1137am HST, here in Bend it’s hot, what else is new! Bob and his cousin Pat and I just got back from eating lunch at a Mexican food restaurant, where we were able to eat out in the shade.

 

Hawaii’s Broad Brush Weather Overview:  Light to moderate trade winds will bring a few brief showers, mainly to windward areas, before gradually diminishing Sunday. Light and variable winds thereafter will result in mostly clear nights and mornings, and warm and muggy afternoons and evenings through Wednesday. Showers will be limited, and most areas will be dry. Cooling trade winds will return by Thursday, and remain breezy into next weekend.

Hawaii’s Weather Details:  After one more day of trade winds, light winds and mostly dry weather will prevail well into next week. High pressure cells centered far northeast and northwest of the islands, are supporting the current light to moderate trade wind flow, with wind speeds up slightly from yesterday.

In response to a low passing north of the islands, the local pressure gradient will become quite slack, and winds will be light and variable Sunday night through Tuesday night. As the low slowly dissipates, high pressure building far northeast of the area will promote a light southeast flow Wednesday, and a strengthening trade wind flow Thursday. Breezy trade winds are expected into next weekend.

In the short term, best chance of showers will be windward as trades persist. The light winds will result in mostly clear nights and mornings as overnight land breezes develop. This will be followed by warm and muggy afternoons, with sea breezes driving the formation of interior clouds and isolated showers. There could be a bit more cloud and shower coverage across Kauai, as a dissipating frontal boundary brings increased moisture as it nears Tuesday. A low cloud band now about 275 miles north of Kauai, will likely dissipate as it nears Kauai Sunday.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Vog map animation

Hawaii’s Marine Environment:  Moderate to fresh easterly trades will continue over the windier channels and waters around Maui County and the Big Island, while light to moderate breezes continue elsewhere. Winds will trend down Sunday through early next week, as a diminishing frontal boundary drifts southward into the area (winds potentially becoming light and variable beginning on Monday).

Surf along north-facing shores will steadily lower through Monday, as a north swell that peaked early Friday fades. Guidance continues to show a gale developing to our north this weekend along an old frontal boundary, with a decent sized area of strong- to gale-force northerly winds focused at the islands around 700 nautical miles away. This will generate a larger north swell that will arrive Monday night, then peak Tuesday night.

Surf along south-facing shores will remain small through the upcoming week, with mainly a combination of southeast and background south-southwest swells. Guidance does show a storm-force low passing south of New Zealand, with seas peaking around 30 ft east-southeast of New Zealand. Although the bulk of this energy is focused at Central America, we should see a small south-southwest swell from this source next weekend (09/14-09/15).

Surf along east-facing shores will remain small and choppy through early next week, due to the lack of fresh to strong breezes upstream of the state over the eastern Pacific.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclon

>>> Central Tropical Atlantic:

Shower and thunderstorm activity associated with an area of low pressure over the central tropical Atlantic has begun to show signs of organization. Gradual additional development is possible, and a tropical depression could form while the system meanders over the central tropical Atlantic through Monday and then moves generally westward at about 10 mph through the rest of next week.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 7 days…medium…50 percent

>>> Eastern and Central Tropical Atlantic:

Disorganized showers and thunderstorms associated with a trough of low pressure are located several hundred miles southwest of the Cabo Verde Islands. The disturbance is expected to move very little during the next few days until it potentially interacts with a tropical wave that is forecast to move off the west coast of Africa by early Monday. Environmental conditions are expected to be favorable for gradual development of this system, and a tropical depression could form by the middle or late portions of next week. The system is expected to begin moving slowly westward by the end of the week.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…40 percent

Caribbean Sea:  There are no active tropical cyclone

Gulf of Mexico:  There are no active tropical cyclone

>>> Western Gulf of Mexico:

Invest 91L

An area of low pressure located over the Bay of Campeche is producing disorganized showers and thunderstorms. This disturbance is forecast to drift slowly northward during the next several days while it interacts with a frontal boundary. Environmental conditions are forecast to become more conducive for development, and a tropical depression is likely to form while the system moves generally northward near or along the Gulf coast of Mexico and Texas through the middle of next week. Interests along the western Gulf of Mexico coast should closely monitor the progress of this system.

* Formation chance through 48 hours…medium…60 percent
* Formation chance through 7 days…high…80 percent

Northeastern Pacific:  There are no active tropical cyclones

>>> Offshore of Southwestern Mexico:

An area of low pressure is forecast to form during the early to middle part of next week, near or just to the south of the coast of southern or southwestern Mexico. Environmental conditions could support gradual development of this system thereafter while it moves generally northwestward, near the coast of southwestern Mexico.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…low…30 percent

Interesting:  Study Shows How Oceans Are Key to Addressing Global Challenges

New research shows how oceans can be used to help address major challenges such as the shortage of antimicrobial medicines, solutions for plastic pollution and novel enzymes for genome editing.

In the past 20 years, scientists have greatly increased the number of microbial genomes they have collected from the ocean. However, using this information for biotechnology and medicine has been difficult.

For this new study, led by BGI Research in China in collaboration with the Shandong University, Xiamen University, the Ocean University of China (OUC), the University of Copenhagen (Denmark) and the University of East Anglia (UEA) in the UK, researchers analysed almost 43,200 genomes of micro-organisms (bacteria, archaea) from marine samples, uncovering a wide range of diversity with 138 distinct groups.

They provide new insights into how genome sizes evolve and, for example, how ocean microbes balance having CRISPR-Cas systems – part of their immune defense – with antibiotic resistance genes. Many of these genes are activated by antibiotics to help the microbes survive.
