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 depression Karina far to the east-southeast…as
well as category 2 hurricane Marie closer to Mexico – neither of which threaten
Here’s a real time wind profiler showing several counter-clockwise rotating
low pressure systems…along with hurricane Marie far east – here’s a
looping satellite image of Marie
Moderately strong trade winds continue…windward showers locally at times
~~~ Hawaii Weather Narrative ~~~
Ongoing trade winds continuing into the new 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, near 1028 millibar high pressure system located far to the northeast of the state. At the same time, there’s a hurricane, and a weakening tropical depression in the eastern Pacific. Our trade winds will remain light to moderately strong through mid-week…and then back down some Thursday into the weekend.
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 to the 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 through the foreseeable future.
Meanwhile, the tropical ocean far to our east remains active…in relation to tropical cyclones. However, the computer models are keeping tropical systems well away from Hawaii through this week. In contrast to our rather quiet reality here in the central Pacific, the eastern Pacific has two tropical cyclones churning the waters now, one of which is a category 2 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 likely tamp down our trade winds, 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 Monday 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 southwest of Bermuda – 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.
1.) A tropical wave located about 900 miles east of the Lesser Antilles continues to produce disorganized showers and a few thunderstorms. Environmental conditions are not expected to be favorable for significant development during the next couple of days, but could become more conducive by the end of the week or this weekend while the system moves westward to west-northwestward at about 15 mph.
* Formation chance through 48 hours...low...near 0 percent * Formation chance through 5 days...low...20 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.) Disorganized showers and thunderstorms over the northern Gulf of
Mexico are associated with a trough of low pressure. Upper-level
winds are not expected to be conducive for significant development
while the system moves to the west-southwest at 5 to 10 mph.
* 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 depression 11E (Karina) remains active in the northeast Pacific, located about 1210 miles west-southwest of the southern tip of Baja California – wind speeds 30 mph. Here’s the NHC graphical track map…along with a satellite image – here’s what the computer models are showing about this depression.
Hurricane 13E (Marie) remains active in the northeast Pacific, located about 605 miles west-southwest of the southern tip of Baja California – wind speeds 100 mph. Here’s the NHC graphical track map…along with a satellite image – here’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.
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: Levels of Air Toxics decreasing across US Cities – More and more people are living in our cities. They are great places to live, exciting, good jobs, great night life, but also sometimes congestion and unhealthy air quality. The latter problems are improving, however. Efforts to make cities livable without driving are paying off. Bike lanes, bike sharing, and efforts to reduce auto traffic and congestion are helping to improve the air quality in our cities.
The U.S. Environmental Protection Agency (EPA) this week released its Second Integrated Urban Air Toxics Report to Congress – the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics.
“This report gives everyone fighting for clean air a lot to be proud of because for more than 40 years we have been protecting Americans — preventing illness and improving our quality of life by cutting air pollution – all while the economy has more than tripled,” said EPA Administrator Gina McCarthy. “But we know our work is not done yet. At the core of EPA’s mission is the pursuit of environmental justice – striving for clean air, water and healthy land for every American; and we are committed to reducing remaining pollution, especially in low-income neighborhoods.”
Using national emissions and air quality data, the Urban Air Toxics Report shows the substantial progress that has been made to reduce air toxics across the country since the Clean Air Act Amendments of 1990.
– A 66 percent reduction in benzene;
– A nearly 60 percent reduction in mercury from man-made sources like coal-fired power plants;
– An 84 percent decrease of lead in outdoor air, which slows brain development in children;
– The removal of an estimated 1.5 million tons per year of air toxics like arsenic, benzene, lead and nickel from stationary sources and another 1.5 million tons per year (about 50 percent) of air toxics from mobile sources. This is significant because air toxics (also referred to as hazardous air pollutants or HAPs) are known or suspected of causing cancer and can damage the immune, respiratory, neurological, reproductive and developmental systems;
– And, approximately 3 million tons per year of criteria pollutants, like particulate matter and sulfur dioxide, have been reduced as co-benefits of air toxics reductions.
“Reducing toxics is a top priority for EPA, and even with this progress, we continue to improve our understanding of them, so we can effectively reduce remaining risks, particularly in overburdened communities. EPA’s Plan EJ 2014, is making sure environmental justice is addressed in programs and policies across the agency. EPA is working closely with state, local and tribal agencies to promote area-wide and regional strategies to address air toxics and support a number of community-based programs that help communities understand, prioritize and reduce exposures to toxic pollutants in their local environment. For example, in Indianapolis, we are working with partners on the ground through an EPA grant for the “Building Lead Safe Communities” Project in the Martindale-Brightwood and Nearwest neighborhoods. We’re addressing the risk of toxic lead exposure in children through outreach efforts and compiling block level soil lead data, identifying hotspots utilizing air sampling and developing synergistic local solutions.”
