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 is moving by offshore to the south and west of
Hawaii…affecting our weather through Sunday – then turning
drier with better weather later Monday onwards  


Hurricane Warning…for Kauai leeward waters  

Flash Flood Warning…south slopes of the Haleakala Crater –
until 6am /Flash Food Watch…Oahu and Kauai

Tropical Storm Warning…Kauai and Niihau – Kauai channel,
and Oahu leeward waters

Tropical Storm Watch…for Oahu, Kauai northwest waters
including adjacent coastal waters

High Surf Advisory…south and west the Big Island, south
shores of Maui and Lanai 


Small Craft Advisory…for coastal and channel waters



~~~ Hawaii Weather Narrative ~~~




Our local winds will be locally gusty…as Ana moves by to the south and west of the state. 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 a high pressure system to the north-northwest. Meanwhile, hurricane Ana is located over the ocean to the south of Kauai. Winds will be strong in some areas as this unusual tropical cyclone moves by close to the islands, then calming down from the southeast in the wake of this storm…into the new week.
Satellite imagery shows partly to mostly cloudy skies…with lots of rainfall in some areas. Looking at this larger looping satellite image, it shows prominent hurricane 02C (Ana) just to our south…having a counter-clockwise spin. Meanwhile, this looping radar image shows showers falling over the ocean…with locally heavy showers moving over the islands in places. Hurricane 02C (Ana) will bring localized heavy rains with flooding, along with thunderstorms and locally blustery winds to Hawaii into Sunday. Weather will improve, first on the Big Island side of the chain, working westward towards Kauai on Monday. I’ll be back with more updates on all of the above and below, I hope you have a great Saturday night wherever you happen to be spending it! Aloha for now…Glenn.

~~~ Hurricane Ana remains a category 1 tropical cyclone, and is maintaining strength…at least temporarily. The Central Pacific Hurricane Center (CPHC) official forecast track has Ana spinning by just to the south of Hawaii, bringing copious rainfall to some parts of the state. Most of the strongest winds remain offshore, which is a very good thing…as they are sustained to near 80 mph near the center. This hurricane is close enough to Kauai tonight, that the island is under a tropical storm warning. The current track will bring locally gusty winds, very rough surf on our south and west shores, and locally heavy rainfall locally. Please be very careful when out and about…especially while on wet roads driving!

World-wide tropical cyclone activity:


>>> Atlantic Ocean: Hurricane 08L (Gonzalo) remains active, located approximately 265 miles east-northeast of St. Johns, Newfoundland …with sustained winds of near 85 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: Remnant tropical cyclone 20E (Trudy) is dissipating, located approximately 115 miles east-northeast of Acapulco, Mexico…with sustained winds of near 30 mph…with higher gusts. Here’s a graphical track map…along with a satellite image – Final Advisory


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 95 miles south of Lihue, Kauai…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

>>> 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: 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.
