Glenn’s Saturday comments:  I’m here at home in upper Kula, Maui

It’s partly cloudy here in Maui County early this morning, with a low temperature of 50.5 degrees at my place, with the relative humidity 77 percent.

1240pm, it’s mostly cloudy, although I don’t see any showers from my vantage point in upper Kula.

415pm, it’s definitely cloudy here in Maui County, although still dry as far as I can see from here on my weather deck in Kula.

610pm, still very cloudy as this inclement weather pattern approaches the state, and we have some vog here in Maui County.

832pm, all the ingredients appear to be in place for a prolonged period of off and on rainfall here in the islands, some of which will be heavy that could lead to flooding.

Hawaii’s Broad Brush Weather Overview: A developing kona low north of Kauai will travel west of the islands through Monday. East winds will transition to southeast to south tonight, and draw up a more moisture rich air mass across the state the next several days. The vicinity of the low will also cool and destabilize the upper atmosphere. These elements brought on by the low, equate to high probabilities of several days of rain, with locally high rainfall and possible isolated thunderstorms, that will initiate flash flooding. Winds may also strengthen to advisory levels Monday, along with Big Island summits receiving significant snow accumulation the next few days. As ridging builds back in over the islands by the middle of the new week, rain should begin to taper off by Wednesday night.

Hawaii’s Weather Details: Water vapor imagery depicts a developing low north-northwest of Kauai. This kona low settling in west-northwest of Kauai through Monday, will be the impetus for a wet pattern across the Hawaiian Islands, that may persist through Wednesday of next week. Many windward exposures have picked up another half an inch to over two inches of rain since yesterday at this time, with various upper terrain leeward spots adding a few tenths to their early year totals. It will not take much more rain over those areas, with saturated grounds and swollen streams, to create runoff and flooding in future rain.

The location of a slow-moving low west of the islands pulling up a very moist air mass (precipitable waters greater than a very unseasonably high 1.5 inches), signals a higher threat for a multiple day flood event for the state. A Flood Watch remains in effect through Monday afternoon, to account for return periods of cloud bands coming onshore, and putting down a few inches of rain in just a matter of an hour or two. The highest amount of rain is forecast to fall along the southeast to south-facing exposures of Big Island and Maui County, due to the orientation of these cloud bands training onshore over multiple days.

A Winter Storm Watch is in effect from Sunday morning through early Tuesday morning, to account for snow accumulations of greater than half a foot. Higher resolution numerical weather prediction model guidance is showing prime conditions for a potential high snow event atop Big Island summits the next couple of days. A cooling atmosphere above 10,000 feet to below freezing by early Sunday, will create prime conditions for possibly high snowfall rates as rich moisture air ascends Mauna Kea and Mauna Loa’s southern slopes. Gradient winds far downstream of the kona low Monday are forecast to strengthen to near wind advisory magnitudes Monday. Strong winds at the summits will also create low visibility conditions within blowing snow.

As the low continues its westward journey away from Hawaii, and weak ridging builds in over the region, breezy east to southeast winds will weaken Tuesday and Wednesday. A weak troughing pattern will linger over the state throughout the week, so uncertainty exists as to the extent of continued mid-week precipitation. A passing boundary later next week, may strengthen southerly winds ahead of it and increase (primarily western islands) return rainfall late Thursday and Friday.

Hawaii’s Marine Environment: Trade winds will briefly weaken and veer southeastward by tonight across the coastal waters, as a low pressure system develops north of Kauai and begins to track southwestward. As this low passes just west of the state, strong to near gale-force east to east-southeasterly winds are expected to build Sunday evening, then continue through the first half of next week. The disturbance will bring rough seas, periods heavy rain, and isolated thunderstorms.

A moderate, medium-period north to north-northeast swell (360-030 deg) will continue to produce elevated surf, that is just below advisory thresholds along north facing shores. This swell will then slowly decrease through the rest of the weekend. In addition, this swell will likely produce moderate surges for north facing harbors, especially for Kahului and Hilo. A Marine Weather Statement will remains in effect for maritime interests to watch for these impending harbor surges. Meanwhile, a small, medium-period northwest (310-320 deg) swell will gradually decline through Monday. Another small, long period northwest (310-320 deg) swell is expected to arrive on Tuesday.

Aside from areas exposed to wrapping north-northeast swell, surf along east facing shores is expected to lower this weekend as trade winds weaken. However, a fetch of strong to near gale-force winds will significantly increase easterly wind swell Sunday night through the first half of the week, which should exceed advisory thresholds for east facing shores.

Surf along south facing shores will remain tiny through the forecast period.

Peak astronomical monthly tides with water levels running roughly 0.5 ft above normal could produce minor coastal flooding through the weekend, and may be enhanced along north facing shores due to the incoming north swell. A Coastal Flood Statement will remain in effect to highlight this flooding potential, especially during the daily peak high tide cycle.

Interesting:  Global temperature records shattered

Analyzing data from the Copernicus Climate Change Service of the European Union, AFP reports that Central Asia, the Sahel region, and Northern Europe experienced their warmest year on record in 2025.

Although, on a global average, 2025 ranks as the third warmest year after 2024 and 2023, these averages conceal the severe heat extremes faced by many countries.

As many developing nations do not regularly release detailed climate data, AFP conducted an independent analysis using Copernicus’ climate models, measurements from nearly 20 satellites, and data from weather stations worldwide.

Analyzing hourly data since 1970, the study found that in 2025 alone, 120 monthly temperature records were broken across more than 70 countries. These figures highlight the unprecedented speed and scale of global warming.

Central Asia experienced an exceptional year in 2025, with every country in the region breaking its annual temperature record. Tajikistan was among the hardest hit. In this mountainous, landlocked country, temperatures rose more than three degrees Celsius above the 1981–2010 seasonal average, ranking among the world’s largest recorded anomalies.

Only 41 percent of Tajikistan’s population has access to safe drinking water, exacerbating the humanitarian impact of the heatwaves. New monthly temperature records were set throughout most of the year, excluding May to November.

Alongside Tajikistan, Kazakhstan, Iran, and Uzbekistan saw temperatures two to three degrees Celsius above seasonal averages.

The Sahel region of Africa also recorded extreme heat in 2025. In Mali, Niger, Nigeria, Burkina Faso, and Chad, temperatures exceeded seasonal averages by 0.7 to 1.5 degrees Celsius. In Nigeria, the past 12 months were the warmest on record, while in other countries the period ranked among the top four hottest.

The World Weather Attribution Network reported in its 2025 assessment that human-induced climate change has increased the likelihood of extreme heatwaves nearly tenfold since 2015.

In the Sahel, already plagued by poverty, food insecurity, and conflict, rising temperatures have added further pressure on livelihoods and human well-being.

Europe faced an exceptional and dangerous summer in 2025. Switzerland and several Balkan countries experienced summer temperatures two to three degrees Celsius above seasonal averages.

Spain, Portugal, and the United Kingdom endured one of the hottest summers in history, triggering widespread wildfires. Thousands of hectares of forest burned across southern and western Europe, many residents were evacuated, and air pollution reached hazardous levels.

The situation in the UK was further complicated by the driest spring in a century, causing severe water shortages that affected agriculture and urban life.

Northern Europe was relatively spared from the extreme heatwaves that struck southern Europe in late summer but recorded an unusually warm autumn. Norway, Sweden, Finland, and Iceland experienced one of their two warmest years on record, accelerating glacial melt and raising new concerns for the region’s environmental balance.

The year 2025 has made it clear that climate change is not a future threat—it is a present reality.

No matter how global average temperatures are interpreted statistically, this heat directly impacts human health, food security, water supply, and ecosystems.

Scientists warn that unless effective and coordinated global efforts are taken now to reduce greenhouse gas emissions, years like 2025 will no longer be exceptions—they will become the new normal.
