Hawaii’s MountainsHere’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are 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’s Broad Brush Weather Overview: A cold front passing far north of the Hawaiian Islands will weaken the high pressure ridge just north of the state, keeping light to moderate trade winds in the forecast lasting into Wednesday. A stronger cold frontal low pressure system moves into the Central Pacific basin on Wednesday, driving the ridge axis directly over the island chain, and producing light east to southeasterly winds.

The forward motion of the front will likely stall and diminish near Kauai by next weekend. Brief passing showers are possible in this weather pattern favoring the late afternoon to early morning hours.

Hawaii’s Weather Details: Satellite imagery shows a high pressure ridge just north of the islands, with cold frontal systems passing by farther to the north. These low pressure systems will keep the ridge to the north in a weakened state this coming week, keeping trade winds in the light to moderate range lasting into Wednesday. Water vapor satellite imagery shows a narrow upper level trough over the islands, with a weak subtropical jet stream producing bands of cirrus clouds across the eastern half of the state.

A long band of unstable cumulus clouds continues to ride into the islands with the trade winds. This band of clouds is likely from the remnants of an old East Pacific cold front. Brief passing showers will continue in this light to moderate trade wind weather pattern through Wednesday, favoring the late afternoon to early morning hours each day. Shower activity will decrease with drier trends in the forecast on Monday and Tuesday.

By Wednesday, this subtle weather pattern changes once again, as a stronger cold frontal low moves through the Central Pacific basin. Colder air surrounding this system will drive the weakened ridge farther south, with the ridge axis hovering directly over the Hawaiian Islands from Thursday to Friday. Expect light east to southeasterly winds as a cold front approaches the islands from the northwest. Not much in the way of showers during this time period as the ridge over the islands keeps conditions fairly stable, with subsidence temperature inversion heights around 6,000 to 7,000 feet, likely yielding a typical overnight passing shower pattern.

A change to more southerly winds may develop by next weekend, mainly over the western islands from Kauai to Molokai. Southerly winds are shown in the latest American (GFS) and European (ECMWF) models that will bring up additional unstable moisture from the deep tropics, producing humid weather and increasing showers trends. The forward movement of the approaching cold front appears to stall as the boundary dissipates near Kauai.

If these southerly winds do not develop as long range models predict, then a drier southeasterly wind pattern will develop instead. These southerly winds will typically turn the drier leeward southern and western slopes of these previously mentioned islands, into a more cloudy and showery weather pattern.

Fire weather:  Winds and humidity levels will remain below critical fire weather thresholds this new week. Passing showers will trend higher during the typical late afternoon to early morning hours.

Hawaii’s Marine Environment: An area of surface high pressure far northeast of the state will allow for gentle to locally fresh easterly trades to prevail through Thursday. Expect a brief increase of southeasterly winds on Friday, followed by weak flow next weekend, as a frontal system passes by north of the islands. Winds should remain below Small Craft Advisory (SCA) criteria through the period. However, combined high seas are forecast for exposed waters Wednesday into Thursday as a large Northwest swell arrives.

The currently moderate, long period, northwest swell (310-320) has peaked. This swell is still running a foot or two above guidance. Surf will continue to slowly decline. Monday into Tuesday, north shore surf will drop below the seasonal average. Another northwest swell, potentially larger, is expected to arrive Wednesday and peak into Thanksgiving day. If current guidance holds, another High Surf Advisory will be warranted. Surf could possibly reach warning levels if the swell comes in above guidance, as the last several have. This swell will decline Friday into next weekend.

As trade winds weaken over the next couple of days, surf along east facing shores will decline and will be well below seasonal average through much the week. South shore surf will be tiny through much of the week.

Interesting: Monsoon Storms Will Bring Heavier Rains but Become Weaker

Climate change will make monsoon storms in South Asia wetter and weaker, with more storms pushing further inland across India.

Scientists from the University of Reading used 13 climate models to understand how warming temperatures will affect monsoon low-pressure systems. These storms deliver more than half of all monsoon rainfall and nearly all extreme rainfall events across South Asia.

The research, published in the Journal of Climate, found that storms will become about 10% weaker by the time global temperatures rise 3°C above pre-industrial levels. Despite becoming weaker, each storm will produce more rain – up to 28% more for the strongest storms. By the time temperatures reach 2°C of warming, average rainfall from each storm will increase by roughly 10%.

Dr Kieran Hunt from the University of Reading and lead author, said: “How can weaker storms produce more rain? It sounds wrong, but the answer partly lies in changes to moisture patterns. Warming temperatures increase the difference in moisture levels between northern and southern India. Winds ahead of storms push this extra moisture into the rainfall zone, making storms wetter even though their winds are slower.”
