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.

Hurricane Ana will move by offshore to the south and west of Hawaii…affecting our weather through the weekend 


Hurricane Warning…offshore waters beyond 40 miles out to
240 miles from shore

Tropical Storm Warning…for Big Island leeward waters, and
adjacent coastal waters 

Flash Flood Watch…for the Big Island – through 12pm today /
Flood Advisory…all of the Big Island…parts of Oahu – until
730am this morning

Tropical Storm Watch…for the Big Island, Maui County, Oahu
and Kauai County, including adjacent coastal waters

High Surf Warning…west shores of the Big Island – High Surf
Advisory…south shores of the Big Island until 6pm this evening



~~~ Hawaii Weather Narrative ~~~




Our local winds will become stronger from the east and northeast…as Ana moves by to the south and west of the state through the weekend. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profiler of the central Pacific. We find high pressure cells far to the east. Meanwhile, hurricane Ana is located over the ocean to the south…which is forecast to move by offshore to the west of our islands through the weekend. Winds will become stronger as this unusual tropical cyclone moves by relatively close to the islands…then becoming southeast in the wake of this storm into the new week ahead.
Satellite imagery shows partly to mostly cloudy skies. Looking at this larger looping satellite image, it shows prominent hurricane 02C (Ana) to our south…which has a counter-clockwise spin to it. Meanwhile, this looping radar image shows showers falling over the ocean in our area…with locally heavy showers moving over the Big Island…and elsewhere in places. Hurricane 02C (Ana) will bring localized heavy rains with possible flooding, along with thunderstorms and locally blustery winds to Hawaii through the weekend. I’ll be back with more updates on all of the above and below, I hope you have a great Friday night wherever you happen to be spending it! Aloha for now…Glenn.

~~~ Hurricane Ana remains a category 1 tropical cyclone. The Central Pacific Hurricane Center (CPHC) official forecast track has Ana moving by to the south and west of the islands. The track has been gradually edging slightly further offshore to the west of our leeward sides, and will likely change a little bit more over the next few days. However, if the current track, or even one similar to it occurs, some parts of the islands will experience strong winds, very rough surf on our south shores, and locally heavy rainfall…with thunder and lightning possible. This will depend upon just where the center of this tropical cyclone ends up going. It would be wise to keep a close eye on the path of this system!

World-wide tropical cyclone activity:


>>> Atlantic Ocean: Hurricane 08L (Gonzalo) remains active, located approximately 270 miles north-northeast of Bermuda…with sustained winds of near 100 mph…with higher gusts. Here’s a graphical track map…along with a satellite image – and what the computer models are showing.


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: Tropical Storm 20E (Trudy) remains active, located approximately 75 miles east-southeast of Acapulco, Mexico…with sustained winds of near 60 mph…with higher gusts. Here’s a graphical track map…along with a satellite image 


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

>>> Central Pacific: Hurricane 02C (Ana) remains active, located approximately 195 miles south of Honolulu, Hawaii…with sustained winds of near 80 mph…with higher gusts. Here’s a graphical track map…along with a satellite image – and what the computer models are showing

Interesting: How did Icebergs reach Florida in the last Ice Age? – Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21,000 year ago, oceanographer Alan Condron of the University of Massachusetts Amherst has shown that icebergs and meltwater from the North American ice sheet would have regularly reached South Carolina and even southern Florida. The models are supported by the discovery of iceberg scour marks on the sea floor along the entire continental shelf.


Such a view of past meltwater and iceberg movement implies that the mechanisms of abrupt climate change are more complex than previously thought, Condron says. “Our study is the first to show that when the large ice sheet over North America known as the Laurentide ice sheet began to melt, icebergs calved into the sea around Hudson Bay and would have periodically drifted along the east coast of the United States as far south as Miami and the Bahamas in the Caribbean, a distance of more than 3,100 miles, about 5,000 kilometers.”


His work, conducted with Jenna Hill of Coastal Carolina University, is described in the current advance online issue of Nature Geosciences. “Determining how far south of the subpolar gyre icebergs and meltwater penetrated is vital for understanding the sensitivity of North Atlantic Deep Water formation and climate to past changes in high-latitude freshwater runoff,” the authors say.


Hill analyzed high-resolution images of the sea floor from Cape Hatteras to Florida and identified about 400 scour marks on the seabed that were formed by enormous icebergs plowing through mud on the sea floor. These characteristic grooves and pits were formed as icebergs moved into shallower water and their keels bumped and scraped along the ocean floor.


“The depth of the scours tells us that icebergs drifting to southern Florida were at least 1,000 feet, or 300 meters thick,” says Condron. “This is enormous. Such icebergs are only found off the coast of Greenland today.”


To investigate how icebergs might have drifted as far south as Florida, Condron simulated the release of a series of glacial meltwater floods in his high-resolution ocean circulation model at four different levels for two locations, Hudson Bay and the Gulf of St. Lawrence.
