Hawaii’s Mountains – Here’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 Tropical Storm Marie far east of Hawaii
Here’s a real time wind profiler showing a couple of counter-clockwise
rotating low pressure systems…along with Marie far east
Light to moderately strong trade winds continue…windward showers locally
High Surf Advisory…south and east shores of all the islands
~~~ 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 northwest, north and northeast of the state. At the same time, there’s a weakening tropical storm in the eastern Pacific. Our trade winds will be light to moderately strong through the weekend…before picking up again 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 clear to partly cloudy conditions over most of the state…while there are active thunderstorms far offshore in many directions. There’s low clouds being carried our way, which will drop just a few showers locally…mostly along our windward sides during the night and early morning hours. Here’s the looping radar, showing a few showers moving across our island chain, which will continue in an off and on manner…becoming less frequent 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 quickly weakening tropical storm…well offshore from the Mexican coast. As we move through the next several days, 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. Finally, please be careful when going into the ocean over the next several days, especially along the south and east facing shores, where high surf conditions will exist. I’ll be back with more updates on all of the above and below, I hope you have a great Wednesday 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 545 miles south-southwest of Halifax, Nova Scotia – wind speeds 75 mph. Here’s the NHC graphical track map…along with a satellite image – here’s what the computer models are showing about this storm.

Caribbean Sea: There are no active tropical cyclones
1.) A tropical wave located over the eastern Caribbean Sea continues to produce disorganized cloudiness and showers. Upper-level winds are expected to remain unfavorable for development during the next couple of days while the system moves across the eastern and central Caribbean Sea. However, environmental conditions could become conducive for some development when the system moves over the northwestern Caribbean Sea on Sunday and into the southwestern Gulf of Mexico early next week.
* Formation chance through 48 hours...low...near 0 percent * Formation chance through 5 days...low...20 percent
Gulf of Mexico: There are no active tropical cyclones
1.) A weak area of low pressure near the coast of South Texas is producing disorganized showers and thunderstorms. Significant development of this system is unlikely before it moves inland over South Texas and northern Mexico today.
* Formation chance through 48 hours…low…10 percent.
* Formation chance through 5 days…low…10 percent.
Here’s a satellite image of the Caribbean Sea…and the Gulf of Mexico.

Eastern Pacific: Tropical Storm 13E (Marie) is quickly weakening in the northeast Pacific, located about 865 miles west of Punta Eugenia, Mexico – wind speeds 45 mph. Here’s the NHC graphical track map…along with a satellite image – here’s what the computer models are showing about this tropical storm.
Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.
Central Pacific: There are no active tropical cyclones

Northwest Pacific Ocean: There are no active tropical cyclones
South Pacific Ocean: There are no active tropical cyclones
North and South Indian Oceans: There are no active tropical cyclones

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.
