Hawaii’s Mountains – Here’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 Weather Narrative ~~~

 

Glenn’s Monday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s clear here in upper Kula early this morning, while the low temperature was a chilly 49 degrees.

1215pm, clouds have formed around the mountains, while the lower elevation areas, including the beaches, remain sunny to partly sunny as we push into the early afternoon.

Weather Wit of the day:  Icy Roads – New skids on the block

 

Hawaii’s Broad Brush Weather Overview:  A relatively dry and stable airmass will persist through mid-week. Light to moderate east to southeast winds will hold through Wednesday ahead of an approaching cold front.

Sea breezes developing during the day should prompt afternoon clouds and light showers over interior and leeward areas. Land breezes should help to clear out leeward and interior areas each night.

Chances of rainfall should increase late in the week, mainly over Kauai, as the tail-end of a cold front stalls near Kauai on Friday.

Hawaii’s Weather Details:  A ridge of high pressure just north of the state will continue to produce stable and mostly dry conditions, with light to moderate east to southeast winds through the middle of the week. Under this east to southeast flow, the main areas for any passing showers will likely be east Maui or southeast Big Island, although rain amounts should be light due to this stable pattern.

Winds will be light enough for sea breezes to develop each day, which will allow for afternoon clouds and maybe a light shower or two during the afternoons over interior and leeward areas. Land breezes developing at night should allow for clear and cool mornings across most of the state.

Starting Thursday, a cold front approaching the state will cause winds to become more southerly ahead of the front. Models agreement that the front stalls near Kauai on Friday. Rainfall chances will generally increase on Friday mainly over Kauai, but the amount rainfall will depend on where the front ends up stalling.

With precipitable water values increasing to around 1.7 inches based on the latest GFS model, there definitely will be potential for heavy showers on Kauai on Friday. At this time instability does look limited, so the threat for thunderstorms looks to be low.

Hawaii’s Marine Environment:  Weak surface ridging north of the islands will steer light to moderate ESE winds through Wednesday, before turning southerly Thursday and Friday as a cold front approaches from the northwest.

A series of moderate to large long period NW swells will move through the state this week. Currently, a moderate, long period NW (310) swell. Expect this swell to continue to fill in, building surf heights along north and west facing shores to just under advisory levels, before dropping a foot or so tonight.

A slightly larger, long period NW (300-310) swell will build on already elevated seas tonight into Tuesday. Surf heights are expected to reach High Surf Advisory (HSA) thresholds Tuesday for N and W facing shores. A reinforcing pulse of similar size will help keep surf at advisory levels through Wednesday before dropping below advisory thresholds Thursday. A large, long period NW swell (320 degrees) swell is expected to gradually generate High Surf Warning level surf along N and W facing shores Friday, peak Saturday, then slowly subside into early next week.

Surf along E and S facing shores remains small through the period.

Interesting:  Vanilla Farmers Search for a Crop and Conservation Sweet Spot

Vanilla is vital to the livelihoods of farmers in Madagascar, where the globally popular dessert ingredient is the country’s No. 1 export. A fun, thought-provoking game designed by a team of scientists and played by Malagasy vanilla farmers reveals the challenges of payment programs that incentivize forest conservation in the region, according to a study led by the University of California, Davis.

The study, published in the February issue of the journal Biological Conservation, found that even amid volatile markets and climate uncertainties, farmers highly value their vanilla crops, which are tied not only to their livelihoods but also their cultural identity. Yet they also recognize the importance of a balanced land-use approach.

“Vanilla farmers often cultivate far more than just vanilla,” said lead author Marie Fleming, a Ph.D. student in Ecology in the UC Davis Department of Environmental Science and Policy. “They grow within rainfed agroecosystems and deeply understand the value of maintaining a healthy mosaic landscape—one that balances food crops, cash crops, and forests. However, achieving this balance while meeting conservation goals can be challenging as farmers face the pressure to expand croplands.”
