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: A stable and rather dry trade wind weather pattern will prevail through early Friday, with low clouds and brief showers falling primarily along the windward sides of some of the islands. A slight increase in trade wind speeds and windward rainfall…is expected later Friday through the weekend.

Details: A near 1027 millibar high pressure system is centered northeast of the Big Island…with a second high pressure cell north-northwest. Satellite imagery shows mostly clear skies along the leeward shores, with a few low clouds being carried over the windward areas on the gusty trade wind flow. Generally pleasant early spring weather conditions will continue, especially over the leeward beaches.

The high pressure system, which has been maintaining the trade winds across our area, will continue shifting eastward through Thursday. At the same time, a cold front to our northwest will move to a position north of Hawaii. As the front stalls and weakens, the trade winds will diminish, shifting to the southeast…with possible volcanic haze (vog) moving over parts of the smaller islands into Friday. We may see an increase in showers, mainly over Maui and the Big Island as well.

Looking ahead: High pressure will gradually rebuild north of the area, after the stalled front dissipates. This will result in an increase in trade wind speeds later Friday, continuing through the weekend. Meanwhile, the models show an upper level trough of low pressure edging into the area northeast of the Big Island. If this occurs as expected, it would likely produce slightly elevated inversion heights, and potentially lead to an increase in trade wind showers…particularly along windward sides of the eastern islands.

By next Tuesday and Wednesday, a couple of cold fronts may be passing by to the north of our area, which could bring a few clouds and showers across the island chain. However, from this vantage point at least, most of the precipitation looks like it would stay well north of Hawaii.

Marine environment details: The latest models suggest that the trade winds will weaken a bit starting this evening, as surface high pressure shifts further to the northeast of the state. Trade winds are forecast to increase once again Friday into the weekend.

Surf along exposed north and west facing shores of the smaller islands will likely hold at moderate levels through Friday, due to a reinforcing west-northwest swell. Surf along east facing shores will remain small and choppy through the rest of the week…due to moderate trade winds persisting.

For the upcoming weekend, the main focus will be a west-northwest swell generated by a large storm force low east of Japan. This low is forecast to move east-northeast through Thursday night, while maintaining a large area of storm force winds. A large west-northwest swell generated by this low, is forecast to reach the state Saturday, then peak Saturday night into Sunday. Surf will very likely reach advisory levels, and could reach warning levels…along exposed north and west facing shores Saturday night through Sunday night.
Generally pleasant weather today

Southern California Weather Summary: A storm system will move across the area today, bringing showers and the possibility of thunderstorms through the night. Thursday and Friday will be dry with gusty northwest winds. By Friday night and Saturday…another storm system will bring additional precipitation to the area.

There is weather on the day you are born
and weather on the day you die. There is
the year of drought, and the year of floods,
when everything rises and swells,
the year when winter will not stop falling,
and the year when summer lightning
burns the prairie, makes it disappear.
There are the weathervanes, dizzy
on top of farmhouses, hurricanes
curled like cats on a map of sky:
there are cows under the trees outlined
in flies. There is the weather that blows
a stranger into town and the weather
that changes suddenly: an argument,
a sickness, a baby born
too soon. Crops fail and a field becomes
a study in hunger; storm clouds
billow over the sea;
tornadoes appear like the drunk
trunks of elephants. People talking about
weather are people who don’t know what to say
and yet the weather is what happens to all of us:
the blizzard that makes our neighborhoods
strange, the flood that carries away
our plans. We are getting ready for the weather,
or cleaning up after the weather, or enduring
the weather. We are drenched in rain
or sweat: we are looking for an umbrella,
a second mitten; we are gathering
wood to build a fire.
