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.

Tropical Storm Julio poses no danger to the Hawaiian Islands
Here’s a real time wind profiler showing Julio slowly moving away
Sultry, Hot and Sunny during the day…especially near sea level
~~~ Hawaii Weather Narrative ~~~
Gradually returning trade winds into mid-week. 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 moderately strong high pressure systems located to the north and northeast of the state. There’s also a cold front from extending across the area north of the state as well. Tropical storm Julio is in between those weather features and our islands. Our trade winds will return through the next couple of days…lasting through the rest of this week at least.
Satellite imagery shows hardly any clouds over and around the islands, with a band of clouds just to the east of the Big Island…moving westward. Looking at this larger looping satellite image, it shows Julio up to our north…with the counterclockwise rotation of former tropical cyclone Iselle far to the west. Here’s the looping radar, showing hardly any showers, and most of those are out over the ocean…with just a few falling over the islands locally. The returning trade winds around the Big Island will bring some windward showers later tonight, and then on to the other islands thereafter. Our local leeward beaches will remain in good shape, although be careful with the active waves in some areas.
Tropical storm Julio will remain active to the north of our islands…with still higher than normal surf in our area. We may see some clouds, and a few showers, although not many, with lots of sunshine during the days . The one exception could be for locally heavy afternoon showers or thunderstorms on the Big Island slopes…along with some windward biased showers arriving there tonight. The trade winds will return through mid-week across the state…bringing back refreshing weather conditions, although still quite hot during the days. I’ll return 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.
~~~ Tropical Storm Julio: continues to move further away from Hawaii. The latest Central Pacific Hurricane Center (CPHC) forecast estimates the sustained winds are near 65 mph near the center…with stronger gusts.
The Perseids meteor shower will occur late tonight
World-wide tropical cyclone activity:
Atlantic Ocean: There are no active tropical cyclones
1.) Shower activity associated with with a westward-moving broad area of low pressure centered about 750 miles west-southwest of the Cape Verde Islands has diminished. Environmental conditions are not favorable for tropical cyclone formation.
* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 5 days...low…near 0 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
Here’s a satellite image of the Caribbean Sea…and the Gulf of Mexico.

Eastern Pacific: There are no active tropical cyclones
1.) A broad area of low pressure associated with a tropical wave is located a few hundred miles south-southwest of Manzanillo, Mexico. Shower activity has not become any better organized since yesterday, but environmental conditions remain conducive for development, and a tropical depression could form within the next day or two while the system moves west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...medium...50 percent * Formation chance through 5 days...high...90 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: Tropical Storm 10E (Julio) remains active here in the central Pacific Ocean, located about 535 miles north of Kahului, Maui. Here’s the CPHC graphical track map…along with a satellite image
1.) A broad area of disturbed weather is centered about 1500 miles east-southeast of the Big Island of Hawaii. Development of this system, if any, should be slow to occur while it moves west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours…low…10 percent

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: Icequakes triggered by earthquakes – In 2010, a powerful magnitude-8.8 earthquake struck off the coast of central Chile, rocking much of the country and producing tremor as far away as Argentina and Peru. But a new study suggests its effects were felt even farther away – in Antarctica. In the wake of the Maule temblor, the scientists found, several seismic stations on the frozen continent registered “ice quakes,” probably due to fracturing of the ice as the planet’s crust shook.
Earthquakes are already known to affect Antarctica’s ice shelves, thanks to the tsunamis they can spawn. Tsunami waves can propagate for great distances across the ocean; if the waves reach Antarctica’s ice shelves – the floating platforms of ice surrounding the continent – they can push and pull on the ice, promoting fractures and ultimately helping large chunks of ice break off, or calve.
But whether earthquake seismic waves, traveling through the ground, can chip away at Antarctica’s ice sheet – the ice piled on top of the continent – remained an unanswered question. Zhigang Peng, a geophysicist at the Georgia Institute of Technology in Atlanta, found the answer by accident while studying effects of the Chile quake in South America. His team was looking for surface waves – shallow seismic waves that travel along the planet’s crust rather than going deeper into the mantle. Surface waves come in two basic types: Love waves, which shake the ground from side to side; and Rayleigh waves, which move in a rolling motion, compressing and expanding the ground as they travel. Both types of surface waves can in turn trigger numerous micro-earthquakes, called tremor.
Peng didn’t initially intend to look at signals from Antarctic seismic stations, but data from a few somehow sneaked onto their research list. And when his team looked for the surface wave signals at those stations, “we found something very interesting,” Peng says. “We started to find tiny seismic signals that we believe are associated with ice cracking.”
