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

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

509am, it’s clear early this morning here in Kula, with a low temperature of 53 degrees at my place.

1227pm, it’s become partly cloudy in many areas, although sunny skies prevail in many areas as well as we push through this last day of the work week…here in Maui County.

255pm, it’s so sunny and very warm here in upper Kula! I think I’ve forgotten how very warm it feels here in upcountry Maui…in the heart of summer! I remember more afternoon clouds, which tempered the heat, although lately those clouds are nowhere to be seen, at least over my area.

 

Hawaii’s Broad Brush Weather Overview:  Light trades will allow local breezes to dominant the wind regime through Saturday. Trades will strengthen to more gentle to locally breezy magnitudes early next week.

Higher moisture moving in from the east early next week will increase rain chances for more shower coverage. Precipitation will generally favor windward and higher terrain through the overnight into early morning hours.

Hawaii’s Weather Details:  Central Pacific upper level ridging remains weakened by the influence of troughing located northwest of the islands. The surface reflection of this upper trough has caused the pressure gradient back to the surface high centered northeast of Oahu to relax a touch these past few days.

The result has been a lighter regional trade flow. As these winds have backed-off, localized gentle land and sea breezes have ruled many communities’ diurnal wind patterns. These breezes will create more efficient cloud growth and shower development over better wind-protected leeward and interior areas.

As surface high pressure gradually strengthens northeast of the state early next week, the tighter pressure gradient back toward the islands will result in a return of more statewide breezy trades.

There are slightly higher probabilities that next week will be a touch more wet, compared to this past dry week. Weak upper level troughing begins to develop northeast of the area into mid-week. Lowering heights will lead to slightly higher vertical temperature inversions and less stable atmospheric profiles.

Higher mid-level moisture within stronger trades signals a subtly more wet pattern within a less stable environment, from Tuesday through the middle of the week. While thicker clouds and higher shower frequency will still favor windward areas, occasional showers may make it over the leeward communities.

Hawaii’s Marine Environment:  A weak ridge of high pressure north of the state will maintain gentle to moderate trades through around Saturday. As the ridge strengthens late this weekend into early next week, locally strong trade winds may return as early as Sunday afternoon. Moderate to fresh trades are expected during the first half of next week, with borderline Small Craft Advisory conditions expected over the typical wind waters around Maui County and the Big Island.

A new small south-southwest swell is expected to build, with tiny forerunners observed . The swell looks to peak Saturday slightly above the summer average, then slowly decline Sunday into early next week. Otherwise, several small pulses from the south are expected next week, which should keep surf from going flat along south facing shores.

A few tiny pulses from the north-northwest are expected during the next few days, and will likely keep the surf from going completely flat along north facing shores through the weekend. Wind waves generated by the trade winds will gradually decline through Friday as the trades ease. Small east swells from increased east Pacific tropical cyclone activity may arrive over the weekend, leading to a subtle increase in surf heights.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean: 

Post-Tropical Cyclone 04L (Debby)…is located about 140 miles east-northeast of Montreal, Quebec…according to the NHC Advisory number 31

AREAS OF HEAVY RAINFALL CONTINUE ACROSS PORTIONS OF NEW ENGLAND AND SOUTHERN QUEBEC…IMPROVING CONDITIONS EXPECTED SATURDAY MORNING AS DEBBY MOVES RAPIDLY TO THE NORTHEAST

The post-tropical cyclone is moving toward the northeast near 39 mph and this motion is expected to continue. Maximum sustained winds are near 35 mph with higher gusts. Little change in strength is forecast during the next 48 hours.

>>> Near the Lesser and Greater Antilles:

Shower and thunderstorm activity has increased some in association with a tropical wave located roughly halfway between the Cabo Verde Islands and the Lesser Antilles. Gradual development of this system is possible during the next couple of days while it moves westward to west-northwestward across the central tropical Atlantic. Afterwards, conditions are expected to become more conducive for development and a tropical depression is likely to form by the early to mid part of next week while the system approaches and then moves near or over the Lesser Antilles. The system is forecast to continue moving generally west-northwestward and could approach portions of the Greater Antilles by the middle to latter part of next week.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 7 days…high…80 percent

Caribbean Sea:  There are no active tropical cyclones

Gulf of Mexico:  There are no active tropical cyclone

Northeastern Pacific:  There are no active tropical cyclone

 >>> South of  Southern Mexico:

Showers and thunderstorms remain disorganized in association with a broad area of low pressure located a couple hundred miles south of the coast of southern Mexico. Some development of this system is possible during the next several days while it moves west-northwestward at around 15 mph, parallel to the coast of southern and southwestern Mexico. By early next week, the system is forecast to move into a more stable environment, limiting additional development.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 7 days…low…30 percent

Interesting:  Estuaries in South Florida Are Warming Faster Than the Gulf of Mexico and Global Ocean

Sea surface temperatures are on the rise around the world, but the problem is pronounced in the estuaries and shallow coastal waters of South Florida.

In South Florida, estuaries have experienced rapid warming over the past two decades. These temperature changes have outpaced trends elsewhere in the ocean, according to a series of studies published by researchers at the University of South Florida College of Marine Science (CMS) and National Park Service.

Using satellite data, the researchers found that sea surface temperatures in four estuaries in South Florida have risen faster than sea surface temperatures in global oceans and the Gulf of Mexico. The findings, published in Environmental Research Letters and Estuaries and Coasts, paint a troubling picture for the marine life that calls Florida home.

“The temperatures in South Florida estuaries are not only rising faster than the global average, but also faster than temperatures in the open Gulf of Mexico,” said Chuanmin Hu, professor of physical oceanography at CMS and co-author of the recent papers. “We even saw more of a response within the estuaries to last year’s marine heat wave.”
