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.

Satellite imagery shows category 1 hurricane Marie far to the east of Hawaii

Here’s a real time wind profiler showing a couple of counter-clockwise rotating
low pressure systems…along with hurricane Marie far east

Moderately strong trade winds continue…windward showers locally at times

~~~ Hawaii Weather Narrative

Ongoing trade winds continuing  this week…although gradually becoming lighter. 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. We have a moderately strong high pressure systems located to the north and northeast of the state. At the same time, there’s a weakening hurricane in the eastern Pacific. Our trade winds will remain moderately strong through Wednesday, and then back down some Thursday through Saturday…before picking up again Sunday into early next week.

Satellite imagery shows scattered clouds over and around the islands...being carried along in the trade wind flow. Looking at this larger looping satellite image, it shows partly cloudy conditions over most of the state…while there are active thunderstorms far to the west-southwest and southeast. There’s low clouds being carried our way, which will drop showers locally…mostly along our windward sides during the night and early morning hours.  Here’s the looping radar, showing some showers moving across our island chain, which will continue in an off and on manner…gradually becoming less frequent later Wednesday through Thursday into Friday morning.

The computer models are keeping tropical systems well away from Hawaii through the next week at least. The eastern Pacific now has only one tropical cyclone churning the waters, which is a weakening category 1 hurricane offshore from the Mexican coast. As we get into the second half of this week, the remnant circulation of former tropical cyclone Lowell…will move into the area well north and northeast of Hawaii. This will interrupt our trade winds to some degree, with a chance of enhanced afternoon clouds and showers over the upcountry slopes, and interior sections into the weekend. I’ll be back with more updates on all of the above and below, I hope you have a great Tuesday night wherever you happen to be spending it! Aloha for now…Glenn.

World-wide tropical cyclone activity:

Atlantic Ocean:
Hurricane 04L (Cristobal) remains active in the Atlantic Ocean, located about 435 miles west of Bermuda – wind speeds 80 mph. Here’s the NHC graphical track map…along with a satellite imagehere’s what the computer models are showing about this storm.

1.) A tropical wave located about 600 miles east of the Lesser Antilles continues to produce disorganized cloudiness and showers. This system is now expected to move generally westward across the Caribbean Sea with little development during the next few days. However, environmental conditions could become favorable for some development by early next week in the western Caribbean Sea or southern Gulf of Mexico.

* Formation chance through 48 hours...low...0 percent * Formation chance through 5 days...low...10 percent

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

1.)  Shower and thunderstorm activity associated with a weak low pressure area located over the northwestern Gulf of Mexico has increased during the past few hours. Some additional development is possible before the system moves inland over southern Texas and northern Mexico on Thursday. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate this system later today, if necessary.

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

Eastern Pacific: 
Hurricane 13E (Marie) remains active in the northeast Pacific, located about 880 miles west of the southern tip of Baja California – wind speeds 75 mph. Here’s the NHC graphical track map…along with a satellite imagehere’s what the computer models are showing about this hurricane.

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

Interesting:  Human influence on the planet’s climate is clear and having “widespread and consequential impacts on human and natural systems,” some of which may be irreversible, says a draft report out today from a United Nations science panel.

“Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia,” the report says. “The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen.”

Changes in many extreme weather and climate events have been seen in the past six decades or so, including fewer cold temperature extremes and more hot temperature extremes.

The U.N. Intergovernmental Panel on Climate Change (IPCC) document is the final part of the group’s Fifth Assessment Report, which synthesizes three earlier large reports on various aspects of climate change. There’s little in this document not covered in the others, but the language is more stark.

The IPCC is a group of researchers and scientists from around the world who monitor recent climate science and release reports every several years about the latest scientific findings.

The report states that the cause of this climate change is man-made emissions of greenhouse gases, which are “the highest in history” and probably “unprecedented in at least the last 800,000 years.”

The recent uptick in carbon dioxide levels is correlated with a rise in global temperatures of about 1.5 degrees since the early 1800s.

“Without additional mitigation, and even with adaptation, warming by the end of the 21st century will lead to high to very high risk of severe, widespread and irreversible impacts globally, ” it says.

The report says that if carbon dioxide and other greenhouse gases continue to be emitted at the current rate, it’s likely that by 2050, temperatures will rise by about 3.6 degrees Fahrenheit, when compared with the temperatures from 1986 to 2005.

By 2100, temperatures could be about 6.7 degrees warmer. Though it wouldn’t occur for hundreds of years, the huge sheet of ice over Greenland could melt entirely, leading to as much as a 23-foot rise in world ocean levels, leaving many coastal cities underwater.
