Hawaii’s MountainsHere’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.

Aloha Paragraphs

Our trade winds will continue blowing…
moderately strong

Fine summer weather…with still some
windward showers at times

We’ll find a modest increase in showers to
our windward sides this weekend…then a
more significant area of showers will arrive
around the middle of next week

~~~ Hawaii Weather Narrative ~~~

Our trade winds will remain active…blowing in the moderately strong range through Saturday. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profile of the central Pacific…focused on the Hawaiian Islands. We have a moderately strong high pressure system located to the north-northeast of the state. The forecast calls for the trade winds to remain active, and perhaps increasing a notch Sunday into early next week.

Satellite imagery shows generally low level clouds over the area. Looking at this larger looping satellite image, it shows lots of thunderstorm activity over the ocean to the south and southeast of the state. Here’s the looping radar, showing some showers falling along the windward sides, with a few more arriving at times over the next several days. The leeward sides will see generally dry weather for the time being.

Typical summer weather expected into first part of the weekend…followed by windward showers Sunday into next Monday. We’re into a normal trade wind weather pattern now…which will last through the first half of the weekend. There will be a few windward biased showers, although the leeward areas should have fine weather prevailing through most of Saturday. The models continue showing the chance of more tropical showers arriving later this weekend into early next week, and then a larger area of showers arriving towards the middle of next week. I’ll be back with more updates on all of the above and below. Aloha for now…Glenn.

World-wide tropical cyclone activity:

Atlantic Ocean: There are no active tropical cyclones

Here’s a satellite image of the Atlantic Ocean

Caribbean Sea:
There are no active tropical cyclones

Gulf of Mexico:
There are no active tropical cyclones

Here’s a satellite image of the Caribbean Sea…and the Gulf of Mexico.

North Eastern Pacific:
There are no active tropical cyclones

1.Satellite images indicate that shower activity has formed closer to the circulation center of a low pressure area located about 1500 miles east-southeast of the Big Island of Hawaii. The low is already producing winds near tropical storm force north of the center, and any additional increase in organization would lead to the formation of a tropical depression. The low is forecast to move westward or west-northwestward at about 10 mph, and upper-level winds are expected to become less conducive for development during the weekend.

* Formation chance through 48 hours…high…80 percent.
* Formation chance through 5 days…high…80 percent.

Here’s a satellite image of this area being referred to as Invest 91E
– along with the hurricane models

An area of low pressure located about 1100 miles southwest of the southern tip of the Baja California peninsula is producing disorganized shower activity. Some development is possible while the system moves westward or west-northwestward at about 10 mph, but upper-level winds are forecast to become unfavorable by early next week.

* Formation chance through 48 hours…low…near 20 percent.
* Formation chance through 5 days…medium…40 percent.

Here’s what the hurricane models are showing

A large area of disorganized showers and thunderstorms, associated with a tropical wave, continues well south of the coast of southern Mexico. Upper-level winds are expected to become somewhat more favorable for development of this system over the next few days while it moves west-northwestward at 10 to 15 mph.

* Formation chance through 48 hours…low…near  20 percent.
* Formation chance through 5 days…medium…50 percent.

Another area of low pressure could form well south of southeastern Mexico by early next week. Some gradual development of this system is possible after that time.
* Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...near 20 percent.

Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.

Central Pacific Ocean:
There are no active tropical cyclones

1.)  A disorganized area of low pressure located about 900 miles southeast of the Big Island of Hawaii continued to produce widely scattered thunderstorms across a broad area. This system may develop during the next few days as it moves westward across the central Pacific.

* Formation chance through 48 hours, medium…30 percent.

Here’s what the hurricane models are showing for this disturbance being referred to as Invest 92E.

There are no active tropical cyclones

South Pacific Ocean:
There are no active tropical cyclones

Interesting: New research compares environmental costs of livestock-based foods Lots of folks love a nice, big, juicy steak, and have no plans of becoming a vegetarian, although there continues to be concern about the resources and costs it takes to produce the proteins of one of the favorite meals around. From the land that is used by livestock to the supplies and energy it takes to raise these animals for our consumption, it is evident that environmental resources take a toll. But what is the real cost?

New research at the Weizmann Institute of Science, conducted in collaboration with scientists in the US, calculates these environmental costs and compares various animal proteins to give a multi-perspective picture of what resources are really being used.

The team looked at the five main sources of protein in the American diet: dairy, beef, poultry, pork and eggs. Their idea was to calculate the environmental inputs — the costs — per nutritional unit: a calorie or gram of protein.

The inputs the researchers employed came from the US Department of Agriculture databases, among other resources. The environmental inputs the team considered included land use, irrigation water, greenhouse gas emissions, and nitrogen fertilizer use.

When the numbers were in, including those for the environmental costs of different kinds of feed, the team developed equations that yielded values for the environmental cost for each food.

The winner? Or should we say, the protein with the biggest footprint? Beef. Which does not come as a surprise. Researchers calculated that in total, eating beef is more costly to the environment about ten times on average — than other animal-derived foods.

Why? For one, cattle require on average 28 times more land and 11 times more irrigation water. They are responsible for releasing 5 times more greenhouse gases, and consume 6 times as much nitrogen, as eggs or poultry. Interestingly, poultry, pork, eggs and dairy all came out fairly similar. Dairy production is often thought to have low environmental impacts, however, that the price of irrigating and fertilizing the crops fed to milk cows — as well as the relative inefficiency of cows in comparison to other livestock — jacks up the cost significantly.

Besides changing the way we think about our diets, researchers hope this study will help inform agricultural policy. Models based on this study can help policy makers decide how to better ensure food security through sustainable practices.
