Air Temperatures The following maximum temperatures were recorded across the state of Hawaii Monday:

83  Lihue, Kauai
84  Honolulu, Oahu
83  Molokai
88  Kahului, Maui
85  Kona, Hawaii
83  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 630pm Monday evening:

Kailua Kona – 82
Hana airport, Maui – 75

Haleakala Summit – 
55 (near 10,000 feet on Maui)
Mauna Kea Summit – 50 (13,000+ feet on the Big Island)

Hawaii’s MountainsHere’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.

~~~ Hawaii Weather Narrative ~~~

Steady trade winds…remaining active through the next week. Here’s a weather chart showing a near 1028 millibar high pressure system located to the northeast of our islands. This high pressure cell, and its associated ridge to our north, are responsible for providing trade winds across our area. The models show a weak cold front well to the north of the state, moving by from west to east by mid-week. This weather feature may slow down our trade winds a notch through Friday, although they won’t go away altogether by any means. As we get into the weekend, we’ll likely see them take back that notch…into next week.

A trade wind weather pattern will prevail, with off and on windward showers. Satellite imagery shows high cirrus clouds over and to the south and southeast of the Big Island, and near Kauai and Oahu too. At lower levels, there’s cumulus and stratocumulus to the north through east of the islands…being carried in our direction on the trades. These clouds will drop showers at times as they arrive. Here’s the looping radar image, showing some of these showers passing by along our windward coasts and slopes, and over the offshore waters as well. As the trade winds remaingusty, some of these showers will spread over into the leeward sides at times. I’ll be back a few more times during the evening with more weather updates, I hope you have a great Monday wherever you’re spending it! Aloha for now…Glenn. 

World-wide tropical cyclone activity:

Atlantic Ocean/Caribbean Sea: Tropical Depression 02L remains active over Belize. This depression was located about 40 miles northwest of Monkey River Town, Belize. Maximum sustained winds were 30 mph. The present movement was west-northwest at 09 mph. Here’s the National Hurricane Center’s (NHC) graphical track map, along with a satellite image. Here’s what the computer models are showing. This tropical depression will bring lots of rainfall, flooding at times locally, as it moves across the Yucatan Peninsula of Mexico.



Gulf of Mexico: There are no active tropical cyclones


Eastern Pacific:
There are no active tropical cyclones


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

Here’s a link to the Central Pacific Hurricane Center (CPHC)…covering our central Pacific.

No Tropical cyclones are expected through Wednesday afternoon


Western Pacific Ocean: Tropical Depression 04W remains active in the Philippine Sea, located about 349 NM east-northeast of Manila, Philippines. Here’s the JTWC graphical track map…along with the satellite image showing 04W. Here’s a link to the Joint Typhoon Warning Center (JTWC).

South Pacific Ocean:
There are no active tropical cyclones


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

  Countries surrounding the Arabian Sea may be at a much higher risk of a major earthquake and tsunami than previously thought, say researchers. A tsunami in this area of the Western Indian Ocean could threaten the coastlines of India, Iran, Oman, Pakistan and further afield. The scientists say further investigation should feed into hazard assessments and planning for such events in the region.

The Makran subduction zone, which lies along the southwestern coast of Pakistan, has low levels of seismic activity, so people assumed it was incapable of generating major earthquakes. But a new analysis published recently in Geophysical Research Letters (30 April) used thermal modelling to show that the rupture zone may be longer and wider than previously thought. This, in combination with thick sediments on the plate being pushed under, makes an earthquake more likely.

The models indicate that earthquakes similar in magnitude to the earthquake in Sumatra, Indonesia, in 2004 that triggered a tsunami, killing more than 230,000 people, could occur in the region.

“Past assumptions may have significantly underestimated the earthquake and tsunami hazard in this region,” says the study’s lead author, Gemma Smith, who is based at the University of Southampton in the United Kingdom.

The Makran subduction zone has previously recorded an earthquake in 1945 of 8.1 magnitude and another in 1947, of 7.3 magnitude.

“The Makran may be capable of significantly higher magnitude earthquakes — of up to 8.5-9.2 magnitude, due to the unusually wide potential rupture zone and thick sediment on the subducting plate,” says Smith.
