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.

Aloha Paragraphs

Hurricane Oho to our southeast…with a low pressure system far
to the north-northeast of the state – along with its loosely associated
cold front passing down through the state

Here’s a wind profile…of the well offshore from the islands –
with a closer view of the Hawaiian Islands

Hurricane Oho will remain offshore to the southeast,
east and northeast of the Big Island

Close-up view of Hurricane Oho

Hurricane Oho to our southeast 

Partly to mostly cloudy…with a southwest to northeast
showery cloud band sliding down over Maui County…
reaching the Big Island tonight – with Hurricane Oho in
view south-southeast of the Big Island

There are showers, mostly over windward Oahu, Maui County
and the Big Island – looping radar image

 
Hurricane Warning…offshore waters beyond 40 miles
southeast of the islands

Flood Advisory…Waipio Valley near Kapaau, Honokaa,
Kamuela, Laupahoehoe, Kukuihaele, Paauilo, Halaula,
Hawi and Makukona…on the Big Island

~~~ Hawaii Weather Narrative ~~~

Trade winds will remain active over the islands…moderately strong and gusty at times. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a wind profiler of the central Pacific. We find high pressure systems well to the northwest and northeast of the state. At the same time, we find tropical systems to our southwest, south and southeast. Finally, there’s a gale low pressure system to our north…with an associated cold front in our area. Our winds are arriving from the trade wind direction, and will continue to do so, although as Hurricane Oho moves by to our east and northeast, our local winds may be influenced to some degree...although this isn’t a sure thing by any means.

We’ll find showers shifting over the eastern islands…into Tuesday morning. An old cold front has brought showers to Oahu, and is now bringing its rain, some locally heavy, southeast over Maui County…and then the Big Island by Wednesday morning. As Hurricane Oho gets into the area east and northeast of the islands, the trade winds will carry showers into the windward sides, although perhaps most notably on Maui and the Big Island with time. There’s already some showers over the ocean to the southeast of the Big Island Monday evening. Looking into the second half of this week…generally fine trade wind weather pattern is expected to return. However, it should be pointed out that we won’t likely be done with tropical moisture completely, as the GFS model shows tropical moisture coming up over the Big Island and perhaps Maui, later this coming weekend into early next week.

Here on Maui…It’s 530am Monday morning with clear to partly cloudy skies. There seems to be a little haze in the air this morning. / Skies are becoming more cloudy now that we’re taking aim on the noon hour, although I don’t see any showers yet. The satellite image above shows a distinct cold front over Oahu, which will be heading down toward Molokai, and the rest of Maui County later today into the evening…bringing showers along with it.

– Afternoon is upon us, and the clouds are increasing too, with showers falling in some areas. As we can see by looking at the satellite images above, and especially the radar image, Oahu and Maui County are on the receiving end of most of our showers. / 415pm and it’s working up to rain, and is already raining in many parts of Maui already. This is the showery frontal cloud band that dumped on Oahu last night into today, and will bring its precipitation to bear over us now. You folks on the Big Island may get showers coming up from the southeast and down from the northwest with this cold front tonight as well…very interesting!

– It’s getting on towards sunset now, and I can see lots of showers down in the central valley, and friends in Kihei told me it has been showering down there during the afternoon. Here in Kula, it hasn’t quite arrived, although it is not far away…that’s for sure. At 630pm the light rain finally arrived here in Kula, as it slowly, ever so slowly moves southeast deeper in the state. / At near 830pm, it’s been lightly raining here in Kula, although there was a flash flood warning in effect for the windward coasts and slopes of east Maui…it’s coming down way heavier over that way. A flood advisory was also active over Molokai and about half of Maui…the northeast portions for the most part. Both of these have ended.

– It’s 2am Tuesday morning, and its still cloudy, foggy, and with a constant light rain…it has rained since around 6pm Monday evening! It’s just a good old fashioned soaking rain, and has kept me awake much of the night.

I’ll be back with many more updates on all of the above and below, I hope you have a great Monday night wherever you’re spending it! Aloha for now…Glenn.

World-wide tropical cyclone activity:

>>> Atlantic Ocean:

Hurricane 11L (Joaquin) remains active, located 665 miles south-southwest of Cape Race, Newfoundland, with sustained winds of 80 mph (category 1 hurricane). Here’s the NHC graphical track map, along with a satellite image of this system…and what the computer models are showing

1.)   A tropical wave located about 850 miles east of the Lesser Antilles is producing disorganized shower and thunderstorm activity. Upper-level winds are expected to remain unfavorable for tropical cyclone formation for the next few days, but they could become a little more conducive by the weekend. However, any development of this disturbance should be slow to occur while it moves west-northwestward at about 15 to 20 mph over the next several days.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 5 days…low…20 percent

Here’s a satellite image of the Atlantic Ocean

>>> Caribbean Sea: There are no active tropical cyclones

>>> Gulf of Mexico: There are no active tropical cyclones

Here’s a satellite image of the Caribbean Sea…and the Gulf of Mexico

Here’s the link to the National Hurricane Center (NHC)

>>> Eastern Pacific: There are no active tropical cyclones

1.)  An area of low pressure is expected to form about 1000 miles southwest of the southern tip of the Baja California peninsula within a few days. Some gradual development of this system is possible late this week while this system moves west-northwestward.

* Formation chance through 48 hours…low…near 0 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.

>>> Central Pacific:

Hurricane 07C (Oho) remains active, located 395 miles southeast of Hilo, Hawaii, with sustained winds of 75 mph. Here’s the CPHC graphical track map, along with a satellite image of this system…and what the computer models are showing

1.)  Shower and thunderstorms associated with former tropical depression Eight-C located around 1500 miles southwest of Honolulu, Hawaii have increased in coverage. However, upper-level winds will likely inhibit redevelopment of this system before it crosses the international date line later today or tonight.

* Formation chance through 48 hours, low…near 0 percent
