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 ~~~

The trade winds will be lighter, with localized daytime sea breezes…through Friday morning. Here’s a weather chart showing a near 1030 millibar high pressure system located to the northeast of our islands. This high pressure system will weakening now, as an area of low pressure edges closer to the state. The models are pointing out that it will take until Friday into the weekend…before the trade winds will rebound. As these trades become lighter, there will be onshore sea breezes occurring in our leeward sections, making for rather hot and muggy weather during the days. In other words, we’ll see a combination of lighter trade winds, and a light wind convective weather system through Thursday.

Satellite imagery shows patches of lower level clouds around the state, especially over and around the Big Island and windward Maui County. Here’s the looping radar image, showing showery clouds being carried along in the weakening trade wind flow, arriving along our windward sides for the most part…although over the mountains in places too.  Here’s a looping satellite image – showing light to moderately heavy showers falling offshore to the southwest of the islands…and along the Kona slopes of the Big Island too. Meanwhile, the upper level trough of low pressure nearing the state, will enhance whatever showers that are falling over the next several days. There may be some locally generous showers falling at times, along the windward sides, and over the leeward slopes as well during the upcoming afternoon hours. I’ll be back with more updates on all of the above during this holiday. Aloha for now…Glenn.

Here at my place in Kula, Maui, it was partly to mostly cloudy, the air temperature was 65.5F degrees – at 815pm this evening.

World-wide tropical cyclone activity:

Atlantic Ocean/Caribbean Sea: There are no active tropical cyclones / Here’s a link to the National Hurricane Center in Miami…which covers tropical cyclone activity in the Atlantic, Caribbean Sea…and the Gulf of Mexico. The hurricane season in the Atlantic, Caribbean, and the Gulf of Mexico all begin as of June 1.

Gulf of Mexico: There are no active tropical cyclones

Eastern Pacific Ocean: There are no active tropical cyclones / SATELLITE DATA AND SHIP REPORTS INDICATE A NEARLY STATIONARY LOW PRESSURE SYSTEM LOCATED ABOUT 190 MILES SOUTH OF SALINA CRUZ MEXICO IS GRADUALLY BECOMING BETTER DEFINED. ALTHOUGH ASSOCIATED SHOWER ACTIVITY DECREASED EARLIER TODAY…SATELLITE IMAGES INDICATE THAT THUNDERSTORM ACTIVITY HAS BEEN REDEVELOPING NEAR THE CENTER DURING THE PAST FEW HOURS. IF THIS RECENT DEVELOPMENT TREND CONTINUES… THEN THE FORMATION OF A TROPICAL DEPRESSION OR A TROPICAL STORM COULD OCCUR TUESDAY MORNING. THIS SYSTEM HAS A HIGH CHANCE…90 PERCENT…OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS BEFORE IT MOVES NORTHWARD AND REACHES THE SOUTHERN COAST OF MEXICO. IF A TROPICAL CYCLONE FORMS…A TROPICAL STORM WARNING WOULD BE REQUIRED FOR A PORTION OF THE SOUTHEASTERN COAST OF MEXICO…AND INTERESTS IN THAT AREA SHOULD CONTINUE TO MONITOR THE PROGRESS OF THIS SYSTEM. REGARDLESS OF DEVELOPMENT…HEAVY RAINS ARE LIKELY OVER PARTS OF SOUTHERN MEXICO AND WESTERN CENTRAL AMERICA DURING THE NEXT FEW DAYS. THESE RAINS COULD PRODUCE LIFE-THREATENING FLASH FLOODS AND MUD SLIDES.

Here’s today’s active tropical systems…and Investigation areas

A WESTWARD-DRIFTING LOW PRESSURE SYSTEM LOCATED ABOUT 825 MILES SOUTHWEST OF MANZANILLO MEXICO CONTINUES TO PRODUCE DISORGANIZED SHOWERS AND THUNDERSTORMS. DEVELOPMENT…IF ANY…OF THIS SYSTEM SHOULD BE SLOW TO OCCUR…AND IT HAS A LOW CHANCE…10 PERCENT… OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

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 / Here’s a link to the Central Pacific Hurricane Center (CPHC)…covering our central Pacific. The hurricane season in this part of the Pacific begins as of June 1st.

Western Pacific Ocean: There are no active tropical cyclones / Here’s a link to the Joint Typhoon Warning Center (JTWC), which covers tropical cyclone activity in the western Pacific, and the North and South Indian Ocean…and adjacent Seas.

South Pacific Ocean: There are no active tropical cyclones

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