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.

Close-up satellite image of category 1 hurricane Julio
Our trade winds will continue blowing…moderately strong
through Wednesday – with changes in speed and direction
expected as two tropical cyclones move over, or close to
the Hawaiian Islands later Thursday into Friday and then
again later this coming weekend
A relatively dry atmosphere will prevail through Wednesday,
with some windward biased showers…falling mostly during
the night and early morning hours
Looking ahead, we’ll find tropical cyclone Iselle arriving
here in the island area later Thursday into Friday
Here’s a real time wind profiler showing category 1 hurricane
Iselle to the east-southeast of Hawaii – here’s an animated
satellite image of Iselle
Hurricane Julio is following closely in the wake of Iselle…
both of which could bring windy and rainy weather our way,
along with high surf to our eastern shores
Tropical Storm Warning…Thursday through Friday
over Hawaii’s offshore waters
(A tropical storm warning means that sustained winds of 39 to 73
mph are expected within the specified area within 36 hours)
Tropical Storm Watch…in effect for the Big Island – and
now including the islands of Maui County
(A tropical storm watch means that tropical storm conditions are
possible within the next 48 hours )
[A tropical storm is an organized system of strong
thunderstorms with a defined surface circulation and
maximum sustained winds between 39 and 74 mph]
Flash Flood Watch…for the State of Hawaii – Tropical
cyclone Iselle will bring heavy rains to the islands –
from 4am Thursday through 6am Saturday
~~~ Hawaii Weather Narrative ~~~
Our trade winds will remain active, blowing in the moderately strong range for the most part…locally stronger at times today. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profile of the central Pacific…focused on the Hawaiian Islands. We have a moderately strong high pressure system located to the northeast of the state, with a ridge of high pressure extending west-southwest…to the north of Hawaii. Our winds will begin going through some definite changes as two tropical cyclones move through, or close to the Hawaiian Islands beginning Thursday…through the weekend into next Monday.
Satellite imagery shows scattered low level clouds over or around the islands at the time of this writing…with the outer edge of an area of thunderstorms to our southwest. Looking at this larger looping satellite image, it shows considerable thunderstorm activity over the ocean to the southwest through south of the state…the largest of these areas is tropical storm Geneieve far to Hawaii’s west-southwest. The spinning clouds associated with category 2 hurricane Iselle are evident on the right side of that animated image…which continues to take aim on our fragile islands. Here’s the looping radar, showing just a few scattered showers falling locally along the windward sides and around the mountains, with most of the leeward sides dry now. The cooler hours of the night will help to coax a few showers out of the very clouds that are around…but there won’t be many through most of Wednesday.
We’ll find favorably inclined, trade wind weather conditions…prevailing through Wednesday. Meanwhile, category 1 hurricane Iselle has entered our central Pacific…and will become a big part of our weather situation Thursday and Friday. The forecast has hurricane Iselle being downgraded to a tropical storm as it approaches the Hawaiian Islands, which is a good thing. As this Central Pacific Hurricane Center’s official track map shows, the islands will have this tropical storm moving over, or close to portions of the state later Thursday through part of Friday. The models are showing yet another tropical cyclone moving westward into the central Pacific, a couple of days behind Iselle. This next system is a hurricane called Julio. Julio could bring another round of heavy weather to the islands later this coming weekend into early next Monday. In sum, we’ll very likely see wet and blustery weather, with high surf conditions (east shores) during the Thursday-Friday time frame, and then again later this weekend as Julio moves close…please find more information just below. I’ll be back with more updates on all of the above and below early Wednesday morning, I hope you have a great Tuesday night wherever you happen to be spending it! Aloha for now…Glenn.

~~~ Category 1 hurricane Iselle: Is moving west-northwestward through our central Pacific. The latest Central Pacific Hurricane Center (CPHC) estimate of sustained winds is 85 mph near the center. It will likely remain a hurricane through Wednesday evening, and by Thursday morning, it will have weakened back into a tropical storm. It will remain a tropical storm thereafter, as it migrates over portions of the Hawaiian Islands through Friday. A tropical storm is an organized system of strong thunderstorms with a defined surface circulation and maximum sustained winds between 39 and 74 mph. We will also see high surf arriving ahead of this tropical storm, breaking largest along the easterly shores for a few days.

Eastern Pacific: Hurricane 10E (Julio) remains active as a category 1 hurricane in the NE Pacific Ocean, here’s the NHC graphical track map…along with a satellite image
1.) A surface trough located several hundred miles south-southwest of Acapulco, Mexico is producing disorganized shower and thunderstorm activity. Development of this disturbance, if any, is expected to be slow while the system moves westward to west-northwestward at 10 to 15 mph during the next few days.
* Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent.
Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.

Interesting: A lake appears in Tunisia desert! – Tunisia offers other-worldly landscapes, fantastical and mysterious. Did you know that four of the Star Wars movies were partially filmed in the southern part of the country? (Tunisia had a starring role as the planet Tatooine). Now, adding to the Atlas mountains and Sahara desert, the tiny republic has another tourist attraction — a newborn lake.
Discovered by shepherds just last month in the middle of Tunisian desert, there has been no official explanation for its sudden appearance. Some geologists have proposed that seismic activity may have disrupted the natural water table, pushing water from underground aquifers to the surface. Others disagree.
Authorities have calculated that the lake area exceeds one hectare, with depths ranging from 10 to 18 meters; that indicates a total water volume of one million cubic meters — liquid gold for the drought-ridden country.
Locally dubbed “Lac de Gafsa”, so far more than 600 people have traveled to the pool and a makeshift beach has grown along its shoreline. Authorities have warned that the water, which began as a transparent turquoise until rapidly blooming algae turned it murky green, could be radioactive. That hasn’t deterred visitors who buck the 40°C heat by swimming, diving, and floating atop inflatable rafts.
