~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Thursday comments: I’m home here in upper Kula, Maui, Hawaii

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

435aam, it’s mostly cloudy this morning here in Kula, with a low temperature of 57 degrees at my place.

 

Hawaii’s Broad Brush Weather Overview:  Southerly kona winds will continue pulling up unstable tropical moisture from the deep tropics over the next few days. A kona low remains in place roughly 600 miles north to northwest of the Hawaiian Islands, as a weakening low level trough begins to move into Kauai.

Bands of showers producing moderate to heavy rain and thunderstorms will develop in this tropical air mass and affect most islands through Friday. The kona low will begin to drift away from the state this weekend with improving conditions over the western islands into the upcoming weekend.

As we push into the early part of next week, all islands will see a dramatic improvement in weather conditions as easterly trade winds return.

Hawaii’s Weather Details:  Satellite imagery shows a kona low system roughly 600 miles north to northwest of the Hawaiian Islands, with a weakening trough moving into the islands of Kauai and Niihau from the northwest. Southerly winds ahead of this system continues to pull up deep unstable tropical moisture over the islands.

A combination of local radar and satellite imagery show convective shower bands moving into most of the islands from the south. These shower bands will produce periods of moderate to heavy rain across much of the state through Friday.

Soil moisture levels remains saturated for most areas, which means any additional heavy rainfall could swiftly turn into runoff and a threat for flash flooding. For these reasons a Flood Watch remains in effect for most of the state. The flood threat for the Big Island remains at a lower threat level, therefore the Big Island is not in the watch at this time.

Kauai County and Oahu weather impacts…The low level trough moving into Kauai County this morning will combine forces with the unstable tropical air mass over the next few days. Increasing low level surface convergence, with a trough passing over the islands will help to lift the unstable moisture over the mountain slopes of Kauai and Oahu, increasing the threat for flooding due to moderate to heavy showers and thunderstorms potentially training over the island.

The medium range forecast guidance show drier and more stable east to southeasterly winds as the ridge builds in from the east, and the kona low drifts northward Friday night into Saturday morning. Any delay in the ridge building back in will slow down these improving weather trends this weekend.

Maui County weather impacts…Deep tropical moisture in southerly kona winds, will bring periods of moderate to heavy showers over the islands of Maui County over the next few days. The main threats for Maui County will be if several storms line up over any one location, potentially producing 1 to 2 inches per hour rainfall for several hours.

These small scale convective shower bands are notoriously hard to predict well in advance. These areas affected by this flood threat may often see fair conditions, that then rapidly deteriorate into heavy rain with rapid runoff and flooding in a very short time period.

Big Island weather impacts…Tropical moisture will affect the Big Island into Friday. The southeastern slopes of the Big Island would be in the highest threat level for moderate to heavy rain during this event. Most of the deep convective showers should remain west of the Big Island this week, with just a slight risk of flooding over Hawaii County.

Saturday through Monday…We gradually transition back to a drier weather pattern as high pressure builds in from the east, producing a drier and more stable southeasterly wind flow pattern across the Hawaii region, as the kona low drifts farther northward away from the state. Easterly trade winds should return by Monday.

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

Hawaii’s Marine Environment:  Fresh to locally strong south to southeast winds associated with a kona low north-northwest of the state, will persist through Friday for most waters. A shift out of the east to southeast direction is expected over the weekend through early next week, as it lifts northward and away from the area.

A Small Craft Advisory has been issued for the windward and leeward Big Island waters (Hamakua Coast and waters near South Point). In addition to the winds, expect locally rough seas in heavy showers or thunderstorms that develop over the next few days, with the best chances being over the waters west of Maui County. Seas should remain just below the advisory level over the exposed Kauai waters as a northwest swell moves through.

Surf along south facing shores will remain up through early next week, due to overlapping, south-southwest swells expected. The first will rise, then peaking tonight through Friday, likely reaching the advisory level. As a result, a High Surf Advisory has been issued through Friday.

Expect rough conditions for most southerly exposures due to a combination of the onshore winds, swell, and periodic heavy showers. As this swell slowly eases over the weekend, a fresh south-southwest swell will begin to fill in through the day Sunday. This will peak early next week before easing through mid-week.

Surf along north and west facing shores has trended up on Kauai, with observations coming in larger than expected. Given the energy, heights should remain below the advisory thresholds for north and west facing shores. Expect a similar trend over exposed waters down the island chain, as it continues to build. This will linger into Friday, then ease through the weekend.

Surf along east facing shores will remain well below average through the weekend. An upward trend is possible next week, as the trades return locally and far upstream over the eastern Pacific.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean: There are no active tropical cyclones

Caribbean Sea: There are no active tropical cyclones

Gulf of Mexico:  There are no active tropical cyclones

>>> Tropical cyclone formation is not expected during the next 7 days…for the areas above

Northeastern Pacific: There are no active tropical cyclones

South of the coast of Mexico

>>> An area of low pressure is forecast to form several hundred miles to the south of the Gulf of Tehuantepec within the next couple of days. Gradual development is possible thereafter, and a tropical depression could form over the weekend or early next week, while the system moves slowly to the west or west-northwest, remaining south of the coast of Mexico.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…40 percent

Interesting:  Scientists Want to Know How the Smells of Nature Benefit Our Health


Spending time in nature is good for us. Studies have shown that contact with nature can lift our well-being by affecting  emotions, influencing  thoughts, reducing stress and improving physical health. Even brief exposure to nature can help. One well-known study found that hospital patients recovered faster if their room included a window view of a natural setting.

Knowing more about nature’s effects on our bodies could not only help our well-being, but could also improve how we care for land, preserve ecosystems and design cities, homes and parks. Yet studies on the benefits of contact with nature have typically focused primarily on how seeing nature affects us. There has been less focus on what the nose knows. That is something a group of researchers wants to change.

“We are immersed in a world of odorants, and we have a sophisticated olfactory system that processes them, with resulting impacts on our emotions and behavior,” said Gregory Bratman, a University of Washington assistant professor of environmental and forest sciences. “But compared to research on the benefits of seeing nature, we don’t know nearly as much about how the impacts of nature’s scents and olfactory cues affect us.”
