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 Aloha Friday comments: I’m here at a vacation rental in Sea Ranch, CA

Good day everyone, I hope you have a great Friday wherever you happen to be spending it.

502am, I’m in northern California, and it’s clear to partly cloudy…with a low temperature of 38 degrees.

725am, Kauai is getting beat up, in other words, it’s getting inundated.

415pm, the upper low to the northwest of Kauai is losing its influence over Kauai, although not before dumping some very heavy rains over the Garden Island! Here along the north coast of CA, we have a cold front progressing down the coast, which will bring some spring rains here as well. The temperature is a cool 51.9 degrees, with cloudy skies.

715pm, cloudy with light sprinkles, and the temperature has dipped to 50 degrees.

 

Hawaii’s Broad Brush Weather Overview:  A strong low pressure system northwest of the state brought intense rain and flooding over Kauai last night. Weather conditions have improved and should generally improve, although there’s an outside chance of a downpour.

Another trough will move into the area Saturday night and will linger across the state through early next week. This trough will bring another round of heavy rain starting over Kauai Saturday night into Sunday, Oahu and Maui County Sunday night into Monday, and over the Big Island Monday night into Tuesday.

Flooding will be the main concern as this low pressure trough moves through the state. Conditions should improve later in the week with trades returning during the second half of next week.

Hawaii’s Weather Details:  A strong low pressure system northwest of the state brought heavy rain and numerous thunderstorms over the western end of the state during the past 12 hours. Rainfall totals over Kauai range anywhere from 4 to 12 inches, with the heavier totals focused over south and east Kauai.

Earlier this morning, we had a large band of moderate to heavy rain with embedded thunderstorms over the Kauai Channel and extending into Oahu. As the kona low gradually weakens and lifts further north throughout the day, the instability will also lift further north. Latest satellite and radar imagery is already showing signs of a weakening trend with cloud tops warming this morning.

For rest of the day today, we should see weather conditions generally improving with mainly off and on showers. The threat for flash flooding has decreased over Kauai, but due to the ongoing issues and an outside chance for a heavy shower this afternoon, a Flood Watch still remains in place. The Flood Watch should be cancelled sometime later today.

For Saturday, scattered showers and muggy conditions will continue to linger over the western half of the state. Sea breezes developing during the day should lead to increasing clouds during the afternoon with scattered showers. Over the eastern half of the state, mid to upper level clouds will continue to linger especially over the Big Island. Scattered showers will continue to ride in with the breezy east to southeast winds, with afternoon showers across the leeward slopes.

Starting Saturday night, a trough will dig towards the state and will bring periods of widespread heavy rain across the state. Flash flooding will once again be a concern over Kauai, and with the abundant rain that they received last night, it will not take much to create more flooding concerns. So for Kauai, the threat of heavy rain will begin to increase Saturday night with the heaviest rain likely during the day Sunday.

At this time, the instability looks to be less than what we saw last night, so the threat for severe thunderstorms will remain low. But with precipitable water values increasing, flash flooding will be the main concern. A Flood Watch should be reissued by Saturday morning over Kauai. As the upper level trough continues to dig towards the state, the threat for heavy rain will expand towards Oahu and Maui County Sunday night into Monday and over the Big Island Monday night into Tuesday.

Our typical trade wind weather should return during the second half of next week, as a ridge of high pressure builds north of the state.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map

Marine Environmental Details:  Thunderstorms capable of producing damaging winds, intense rainfall and waterspouts has developed over the coastal and offshore waters around Kauai. The threat for large areas of heavy rainfall and embedded strong thunderstorms around Kauai is likely to persist.

Fresh to locally strong east to southeast winds will ease as the deep low pressure system northwest of the state weakens. A Small Craft Advisory (SCA) has been extended for all waters around Maui County and the Big Island and Oahu Windward waters. As this system passes the state far to the north Sunday into early next week, the winds will steadily veer south to southwest, and potentially return to the fresh category over the western end of the state Sunday. Moderate to fresh northerly winds are possible Monday, with a return of a more typical trade wind pattern by mid-week as high pressure builds to the north.

Small surf will persist across north facing shores over the next several days, with background energy from the northwest and north expected. An upward trend is possible late Sunday as a small north-northwest swell arrives from a system across the far northwest Pacific. This upward trend will continue through the first half of next week as the aforementioned low nearby to the northwest lifts northeastward over the weekend. Heights could reach High Surf advisory levels Monday night through Tuesday night as this swell peaks. Thereafter, expect a gradual downward trend with the swell direction shifting out of the north-northwest by Thursday.

Surf along east facing shores will trend down slightly as locally strong winds trend down over the weekend and veer out of the south. Small surf will persist next week.

Surf along south facing shores remain small with mainly background south-southwest swell expected. The next pulse should hold through the weekend before moving out. If the moderate to fresh south-southwest winds materialize as advertised later in the weekend, conditions may become rough and choppy along southerly exposures.

Interesting:  Ants in Colorado Are on the Move Due to Climate Change

On a hot summer day in 2022, Anna Paraskevopoulos found herself trekking through forests and shrubs in Gregory Canyon near Boulder, flipping over rocks and logs to look for any signs of ants. 

About six decades before that, a team of entomologists had walked on the same trails to record the local ant species, but what Paraskevopoulos saw was very different. Over the past 60 years, climate change has forced certain ant species, unable to tolerate higher temperatures, out of their original habitats in Gregory Canyon.

The resulting biodiversity change could potentially alter local ecosystems, according to Paraskevopoulos, a doctoral student in the Department of Ecology and Evolutionary Biology at CU Boulder. Her research findings appear April 9 in the journal Ecology.

Like all insects, ants are ectothermic, meaning their body temperature, metabolism and other bodily functions depend on the environment’s temperature. As a result, ants are sensitive to temperature fluctuations, making them a good marker to study the impact climate change has on ecosystems.
