Air Temperatures – The following maximum temperatures (F) were recorded across the state of Hawaii Tuesday:

84  Lihue, Kauai
85  Honolulu, Oahu
83  Molokai
88  Kahului, Maui
86  Kona, Hawaii
80  Hilo, Hawaii


Air Temperatures ranged between these warmest and coolest spots near sea level – and on the highest mountain tops on Maui and the Big Island…as of 743pm Tuesday evening:


Port Allen, Kauai – 81
Hana airport, Maui – 77


Haleakala Summit –   52 (near 10,000 feet on Maui)

Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions. Here’s the Haleakala Crater webcam on Maui – if it’s working.

We can use the following links to see what’s going on in our area of the north central Pacific Ocean. Here’s the latest NOAA satellite picture – the latest looping satellite image… and finally the latest looping radar image for the Hawaiian Islands.


~~~ Hawaii Weather Narrative ~~~



A typical summer trade wind weather pattern will continue this week…and on into next week. Here’s a weather chart showing high pressure systems located to the northwest and northeast of the islands. At the same time we have an out of season cold front to our north…and weak tropical systems to our south and southeast. Wind speeds will be in the moderately strong category, locally a bit stronger at times. There’s a chance that our trades will drop a notch late Sunday into early next week…as a unusual cold front moves by to our north.

We’ll see a few windward showers, with generally dry conditions elsewhere. Satellite imagery shows fairly typical low clouds upstream of the islands, which will be carried into the windward sides at times…mostly during the night and early morning hours. Meanwhile, we find scattered areas of high cirrus clouds moving through the state from the southwest…especially around the Big Island at the time of this writing. Here’s the looping radar image, showing a few showers falling along the windward coasts and slopes…with a few elsewhere.


There’s a tropical disturbance in our central Pacific, located well south-southeast of the Big Island.  This area isn’t very pronounced, and has a low 0% chance of developing into a tropical cyclone over the next couple of days. At the same time, there’s a second disturbance further to the east-southeast, with a slightly higher 20% chance of developing. Here’s a satellite picture, with these areas circled in yellow. There’s a chance that the northern fringe of this disturbance, as it moves westward, may drop some showers over the Big Island and Maui Friday into Saturday morning. Otherwise, nothing unusual is in store here in the central Pacific for the time being. I’ll be back again early Wednesday morning with your next new weather narrative from paradise, I hope you have a great Tuesday night wherever you’re spending it! Aloha for now…Glenn.



World-wide tropical cyclone activity:

Atlantic Ocean: There are no active tropical cyclones

 

SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A LOW PRESSURE SYSTEM
LOCATED A FEW HUNDRED MILES EAST-SOUTHEAST OF THE CAPE VERDE
ISLANDS HAVE BECOME A LITTLE BETTER ORGANIZED DURING THE PAST FEW
HOURS.  ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR ADDITIONAL
DEVELOPMENT DURING THE NEXT COUPLE OF DAYS...AND THIS SYSTEM HAS A
MEDIUM CHANCE...40 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING
THE NEXT 48 HOURS.  AFTER THAT TIME...THE LOW WILL BE MOVING TOWARD
COOLER WATER AND DRIER AIR...WHICH COULD LIMIT DEVELOPMENT.  THIS
SYSTEM HAS A MEDIUM CHANCE...50 PERCENT...OF BECOMING A TROPICAL
CYCLONE DURING THE NEXT 5 DAYS.  INTERESTS IN THE CAPE VERDE
ISLANDS SHOULD MONITOR THE PROGRESS OF THIS SYSTEM.


TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE NEXT 48 HOURS

Caribbean Sea: There are no active tropical cyclones

A TROPICAL WAVE OVER THE WESTERN CARIBBEAN SEA IS PRODUCING
DISORGANIZED SHOWER AND THUNDERSTORM ACTIVITY EXTENDING FROM
CENTRAL AMERICA NORTHEASTWARD TO JAMAICA AND EASTERN CUBA.
ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR SOME DEVELOPMENT OF
THIS DISTURBANCE OVER THE NEXT COUPLE OF DAYS AS IT MOVES
NORTHWESTWARD AT 10 TO 15 MPH TOWARD THE YUCATAN PENINSULA AND
SOUTHERN GULF OF MEXICO. UPPER-LEVEL WINDS COULD BE MORE MARGINAL
FOR DEVELOPMENT WHILE THE SYSTEM IS OVER THE GULF OF MEXICO AT THE
END OF THE WEEK. THIS SYSTEM HAS A MEDIUM CHANCE…30 PERCENT…OF
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS…AND A MEDIUM
CHANCE…40 PERCENT…OF BECOMING A TROPICAL CYCLONE DURING THE
NEXT 5 DAYS.

Here’s a satellite image showing the tropical disturbances noted above


TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE NEXT 48 HOURS.


Gulf of Mexico: There are no active tropical cyclones


TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE NEXT 48 HOURS.

Eastern Pacific: There are no active tropical cyclones

AN ELONGATED TROUGH OF LOW PRESSURE IS PRODUCING DISORGANIZED
SHOWERS AND A FEW THUNDERSTORMS ABOUT 1200 MILES EAST-SOUTHEAST OF
THE HAWAIIAN ISLANDS.  ENVIRONMENTAL CONDITIONS ARE EXPECTED TO
CONTINUE TO BECOME LESS CONDUCIVE FOR DEVELOPMENT DURING THE NEXT
COUPLE OF DAYS.  THIS SYSTEM HAS A LOW CHANCE...20 PERCENT...OF
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS...AND A LOW
CHANCE...20 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE
NEXT 5 DAYS WHILE IT MOVES WESTWARD AT ABOUT 15 MPH.


Here’s a satellite image showing this tropical disturbance


Elsewhere, tropical cyclone formation is not expected during the next 48 hours

Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.


Central Pacific Ocean: There are no active tropical cyclones

 

1. An elongated surface trough located about 700 miles south southeast of Hilo, Hawaii is producing disorganized showers and thunderstorms. Environmental conditions do not appear favorable for any significant development near this trough as it continues moving westward at about 15 mph. This system has a low chance, near 0 percent, of becoming a tropical cyclone during the next 48 hours.


2. An elongated surface trough is producing disorganized showers and thunderstorms about 1230 miles east southeast of Hilo, Hawaii. Environmental conditions are expected to become less favorable for development during the next couple of days as this trough moves westward at about 15 mph. This system has a low chance, 20 percent, of becoming a tropical cyclone during the next 48 hours.

Western Pacific Ocean: Typhoon 11W (Utor) remains active, located approximately 152 NM southwest of Hong Kong. Here’s a JTWC graphical track map…along with a NOAA satellite image.


South Pacific Ocean: There are no active tropical cyclones

 

North and South Indian Oceans: There are no active tropical cyclones

Interesting:  Coral Reefs in danger of disappearing – Urgent cuts in carbon emissions are needed if Caribbean coral reefs are to survive past the end of the century, scientists have warned.


A new paper, published in the journal Current Biology, says Caribbean reef growth is already much slower than it was 30 years ago. Its authors say that without serious action on climate change, the reefs may stop growing and begin to break down within the next 20-30 years.


‘The balance between reef growth and reef erosion is changing as we alter the environment,’ says Dr Emma Kennedy of the University of Exeter, who led the study.
‘This means that increasingly, some reefs are breaking down faster than they can replace themselves — essentially they’re being worn away.’


As corals grow they produce limestone skeletons which build up over time into vast reefs. They provide a natural breakwater and a complex three-dimensional habitat, making an ideal home for a vast array of marine species.


‘Healthy reefs are the rainforests of the sea,’ says Kennedy. ‘They provide habitat for over a quarter of all marine species, including many colorful fish and corals.’
