Hawaii’s MountainsHere’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (nearly 13,800 feet high) on the Big Island of Hawaii. This webcam is available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars — and the sunrise and sunset too — depending upon weather conditions.

~~~ Hawaii Weather Narrative ~~~

 

Broad Brush Overview: Remnants of very early season cold fronts will bring some clouds and showers to Kauai and Oahu Wednesday into the night, with dry conditions expected to continue elsewhere. Trades will begin to return Wednesday, and become locally stronger Thursday. With the trades returning, we can expect trade wind showers to favor the windward and mountain areas, especially during the nights and morning hours. The trade winds will then trend lighter Saturday, and continue through the rest of the weekend…into early next week.

Looking Ahead: The trades will return, as the remnants of the fronts to the northwest approach…and move over Kauai and Oahu. Light trades Wednesday will give way to stronger trades Thursday, as a ridge builds north of the islands. This ridge will be disrupted by another front moving from west to east, north of the islands as we head into the weekend. The moisture from this front is currently expected to remain north of the islands, with trade wind showers continuing through the weekend. Tropical Cyclone activity won’t be a threat through at least the next 5-days.

Marine environment details: Winds and seas will remain below Small Craft Advisory criteria through Thursday, although may be required by Friday for the typically windy waters around Maui County and The Big Island…as high pressure builds in to our north.

A series of small southerly swells can be expected through the remainder of the week into the weekend.

An early season north-northwest swell is expected to arrive tonight.  A small west swell is possible Thursday and Friday. A small northwest swell is possible Friday through the weekend…surf heights will remain below advisory levels.

A FASCINATING SHORT SEA STORY
The passenger steamer SS Warrimoo was quietly knifing its way through the waters of the mid-Pacific on its way from Vancouver to Australia. The navigator had just finished working out a star fix and brought the master, Captain John Phillips, the result. The Warrimoo’s position was LAT 0º 31′ N and LON 179 30′ W. The date was 31 December 1899.

“Know what this means?” First Mate Payton broke in, “We’re only a few miles from the intersection of the Equator and the International Date Line”. Captain Phillips was prankish enough to take full advantage of the opportunity for achieving the navigational freak of a lifetime. He called his navigators to the bridge to check & double check the ships position. He changed course slightly so as to bear directly on his mark. Then he adjusted the engine speed. The calm weather & clear night worked in his favor.

The SS Warrimoo lay on the Equator at exactly the point where it crossed the International Date Line! The consequences of this bizarre position were many:

The forward part (bow) of the ship was in the Southern Hemisphere & in the middle of summer.

The rear (stern) was in the Northern Hemisphere & in the middle of winter.

The date in the aft part of the ship was 31 December 1899. In the bow it was 1 January 1900.

This ship was therefore not only in

Two different days,

Two different months,

Two different years,

Two different seasons

But in two different centuries – all at the same time.
