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

Low pressure systems far northeast and north of Hawaii…
tropical disturbance far east-southeast of Hawaii, with
their trailing cold fronts

High cirrus clouds well offshore in several directions

 

A few clear areas…although lots of low clouds

 

Numerous showers locally…a few are quite generous
Looping radar image

Small Craft Advisory…Kauai northwest and leeward waters,
and Maalaea Bay, Maui, Pailolo and Alenuihaha Channels

~~~ Hawaii Weather Narrative ~~~

Moderate trade winds…to become established across the state into Tuesday. Here’s the latest weather map, showing high pressure systems far north and northeast of Hawaii. There’s an area of low pressure well offshore to the northeast of the state, with the tail-end of its associated cold front to our northeast. There’s also a trough of low pressure offshore to the east of the Big Island. The most recent forecast shows the trade winds bringing moderately strong breezes our way into Tuesday…then continuing through the week.

Here’s a wind profile…of the offshore waters around the islands – with a closer view

The trades will carry an area of showery clouds southward through the area this evening into the night…especially over windward and mountain areas. Once this area of enhanced moisture moves through the state by Tuesday morning or so…a more normal amount of clouds and showers will focus primarily across windward and mountain areas. However, given the strength of the trades, an occasional shower may drift into leeward areas of the smaller islands, particularly during the night and early morning hours. The leeward sides will be just fine this week, having high temperatures similar to what we can expect during the upcoming early summer period. As we get into Friday and the weekend, we’ll find an increase in showers, mostly over the windward sides…although not exclusively.

Marine environment details: Above average surf appears likely along southern shores late this week, remaining through the weekend, and carrying into early next week. The latest model guidance reflects this pattern and depicts a very large fetch of gale to storm force southerly winds, associated with this evolving system over the next few days. Advisory level surf appears likely over the upcoming weekend along our leeward beaches.

Out across the Hawaiian waters, moderate to locally strong trade winds will return this week as high pressure builds north of the state. As a result, small craft advisory conditions are expected for the leeward Kauai waters today, then across the Pailolo and Alenuihaha Channels and Maalaea Bay beginning tonight. In addition to the increasing winds, this will translate to choppy surf rising along east facing shores through the week.

 

 
The Napili coast…Kauai

Here on Maui – Early Monday morning is dawning partly to mostly cloudy. Here at my place in upcountry Kula, the air temperature was 59.5F degrees at 540am. Meanwhile, at about the same time, the Kahului AP was reporting light rain, with an air temperature of 72 degrees, while out in Hana it was 75, with 72 at Maalaea Bay…and finally the summit of the Haleakala Crater reporting 46 degrees. / Now at 1015am, the clouds are rather thick and built up over the mountains. I got word that it had been raining already in Kihei! In contrast, it looks nice and sunny down near Paia. Here at my place in upcountry Kula, it’s cloudy, with a couple of light sprinkles once in a while.

– Early afternoon, with a mix of sunshine and clouds. The trade winds are picking up now…gusting to near 30 mph in those locally windiest spots.

– Early evening, with still lots of low clouds around, although not too many showers…with the windward sides being the exception. I anticipate that the windward coasts and slopes will remain rather showery into the early morning hours on Tuesday. We might see a few showers sneaking over into the leeward sides at times here and there as well. / Now at 6pm, I can see showery looking clouds over towards Makawao and Haiku, which seem like they are heading towards Pukalani and even over here towards my place in Kula. / At about 730pm the showers finally arrived, which were light to moderately heavy for about 30 minutes. Now at 830pm, they are gone for the most part, although the eaves are still dripping.

 

World-wide tropical cyclone activity:

>>> Atlantic Ocean: Post-Tropical Cyclone 03L (Colin)

Post-tropical cyclone 03L (Colin) is now dissipating over the Outer Banks, located about 120 miles southwest of Cape Hatteras, North Carolina. Here’s the NHC graphical track map…along with a satellite image…and what the computer models are showing

HAZARDS AFFECTING LAND

RAINFALL: Colin is expected to produce additional rainfall amounts of 1 to 2 inches across far eastern North Carolina and 1 to 3 inches, with isolated maximum amounts of 5 inches, across central Florida through this evening.

STORM SURGE: Water levels remain elevated along the west coast of the Florida peninsula, but are expected to subside by this evening.

Localized coastal flooding and dangerous surf are possible along the Outer Banks of North Carolina within the tropical storm warning area.

WIND: Tropical storm conditions could occur over portions of the warning area through early afternoon.

Here’s a satellite image of the Atlantic Ocean

>>> Caribbean Sea: No active tropical cyclones

>>> Gulf of Mexico: No active tropical cyclones

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

>>> Eastern Pacific: Tropical Depression 01E

Tropical Depression 01E remains active, located about 65 miles south-southeast of Salina Cruz, Mexico. Here’s the NHC graphical track map…along with a satellite image…and what the computer models are showing.

HAZARDS AFFECTING LAND

RAINFALL: The depression is expected to produce total rain accumulations of 4 to 6 inches with isolated amounts of around 10 inches possible through Wednesday over the southern Mexican states of Oaxaca, Chiapas, Tabasco, and eastern Veracruz, and over western Guatemala. These rains could produce life-threatening flash floods and mud slides, especially in areas of mountainous terrain.

WIND: Tropical-storm-force winds, primarily in gusts, are possible in the watch area today.

1.)  A low pressure system located about 1400 miles southwest of the southern tip of the Baja California peninsula continues to produce some showers and thunderstorms, though these are not substantially more organized than observed yesterday. Some development of this system is possible during the next day or two before environmental conditions become less conducive.

Here’s a satellite image of this disturbance, being referred to as Invest 91E…along with what the computer models are showing

* Formation chance through 48 hours…low…30 percent
* Formation chance through 5 days…low…30 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: No active tropical cyclones

No tropical cyclones expected through the next two days…
