Hawaii’s Mountains – Here’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: Light winds will continue today due to a low north-northeast of the state. Clouds and showers will develop again this afternoon as local sea breezes form. Light trade winds are expected to gradually return later tonight and Monday, with brief trade showers mainly over windward slopes. A weak upper-level trough is forecast to develop near the islands Tuesday, which may cause a slight increase in trade showers. Deep tropical moisture will eventually spread up from the southeast over the islands by mid-week, which will result in humid conditions and a wet weather pattern starting Thursday.

Details: The light flow will again allow the development of local sea breeze circulations today. This will cause clouds and showers to form across most upcountry land areas. Light southeasterly winds over the eastern islands will transport volcanic haze (vog) over most of the Hilo and Hamakua Districts on the Big Island today. This haze will also likely spread as far north as parts of Maui County later in the day.

The surface low is expected to weaken as it starts shifting northward away from the area later today and tonight. This will cause the pressure gradient to tighten slightly Monday, allowing gentle trade winds to return across many areas. However, there will still be local sea breezes, and the possibility of partly sunny skies and spotty showers in some leeward sections Monday afternoon. Otherwise, expect brief trade showers mainly over some windward areas as the trades return.

By Tuesday, the trades are expected to increase to locally moderate speeds. At the same time, the models indicate a weak upper level trough will be in the vicinity of the islands. This feature will likely cause a slight destabilization of the atmosphere, and may lead to a modest increase in trade showers. Eventually the trough aloft may result in a weak surface trough developing in the vicinity of the state around mid-week. This feature may cause a brief slow down of the trades over parts of the state Wednesday into Thursday.

Looking Ahead: During the second half of the week, the models continue to show a significant surge of deep tropical moisture approaching the Big Island from the east-southeast late Wednesday. This enhanced moisture will eventually spread up over the rest of the smaller islands Thursday. The forecast is leaning toward a continuation of gentle to locally moderate trades through Thursday night, with strengthening trade winds from Friday into the weekend.

This would suggest that wet trade wind weather conditions with locally heavy windward showers occasionally spreading leeward. However, if a surface trough develops in the vicinity of the state, a more active diurnal convective pattern with local afternoon and evening downpours may develop over some areas. There may also be a hybrid of these two patterns, although its still too early to know which way the pendulum will swing.

Marine environment details: With a slow-moving surface low north of the islands disrupting the overall flow, winds will remain light across the island chain into the new week. Small craft advisories are not anticipated in the near term.

A north-northeast swell was generated by this low, and will keep surf along east facing shores near advisory levels today, when it is expected to peak through early Monday morning. Surf along the north facing shores exposed to this swell is expected to remain below advisory levels. This swell, and its resulting surf…will slowly decline through early this week.

Small reinforcing south-southeast and southwest swells will keep surf from going flat along south-facing shores through most of the week.

>>> Atlantic Ocean: No active tropical cyclones

Shower activity associated with a nearly stationary low pressure system located about 750 miles southwest of the Azores has changed little since yesterday. However, this low still has the potential to become a subtropical or tropical cyclone later today before environmental conditions become unfavorable for development by tomorrow.

* Formation chance through 48 hours…high…70 percent

Interesting: Study finds any activity—from workouts to housework…is good for the heart – An international team of scientists, led by SFU health sciences professor Scott Lear, has found that physical activity of any kind—from gym workouts to housecleaning —can help prevent heart disease and even death.

Lear, who holds the Pfizer/Heart & Stroke Foundation Chair in Cardiovascular Prevention Research at St. Paul’s Hospital, is the principal investigator of the Prospective Urban Rural Epidemiology (PURE) study, which involved more than 130,000 people from 17 countries. The study, published in The Lancet, was carried out by the Population Health Research Institute at McMaster University and Hamilton Health Sciences.

Lear’s team demonstrated that any activity is good for people in raising their heart rates to meet the activity guideline of 30 minutes a day or 150 minutes a week. Researchers found that by meeting these guidelines the risk of death from any cause was reduced by 28 per cent, while heart disease was reduced by 20 per cent, regardless of the type of physical activity.

Lear notes that one in four people worldwide do not meet the current guideline and that number is nearly triple in Canada. According to the researchers, one in 12 deaths could be prevented if everyone was active for at least 150 minutes per week over five years.

The PURE study showed that similar to high income countries, low and middle-income countries also demonstrated the benefits of leisure time activities. “By including low and middle-income countries, we were able to determine the benefits of activities such as active commuting, having an active job or even doing housework,” says Lear.

In order to realize the full benefits of physical activity, Lear says it needs to be incorporated into daily life. “Going to the gym is great, but we only have so much time we can spend there. If we can walk to work, or at lunch time, that will help too.”
