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 1029 millibar high pressure system located to the northeast of our islands. This high pressure system will keep only light east to southeast breezes over the islands for the time being. For the moment, these trades will allow onshore sea breezes to develop during the days, making for rather hot and muggy weather near the beaches. The models are pointing out that it will take until Friday into the weekend…before the trade winds will rebound. These trades should prevail well into June, at least according to what climatology tells us…although the climate records haven’t held up so well lately!

Satellite imagery shows rain bearing clouds over the islands, with even a few thunderstorms locally around the Big Island…along with a band of high cirrus clouds offshore to our east and northeast. Here’s the looping radar image, showing lots of showery clouds over parts of the state. Case in point, the 16.84″ rainfall total in the Koolau Mountains on Oahu…just during the last 12-18 hours! An upper level trough of low pressure near the state, has been responsible for enhancing showers that have fallen lately. This trough made our overlying atmosphere unstable, and in turn very shower prone…with all of the islands having flood advisories active during the day. There will continue to be locally heavy rains falling locally, although they should likely back off after sundown this evening…although not completely. The upper level low pressure system will move away beginning Wednesday, making way for more stable conditions into Thursday, with less of a threat of heavy showers. I’ll be back with your next new weather narrative early Wednesday morning. Aloha for now…Glenn.

Here at my place in Kula, Maui, it was clear to partly cloudy…the air temperature was 66F degrees – at 825pm 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:  Tropical storm Barbara remains active in the eastern Pacific. It is located about 55 miles southeast of Salina Cruz, Mexico. Maximum sustained winds are near 65 mph, with Barbara presently moving more quickly towards the northeast at 13 mph. Here’s the NHC graphical track map, along with a satellite image. Here’s what the weather models are showing for TS Barbara

SHOWER AND THUNDERSTORM ACTIVITY ASSOCIATED WITH THE LOW PRESSURE AREA LOCATED ABOUT 800 MILES SOUTH-SOUTHWEST OF THE SOUTHERN TIP OF THE BAJA CALIFORNIA PENNISULA CONTINUES TO SHOW LITTLE CHANGE IN ORGANIZATION. SOME SLOW DEVELOPMENT OF THIS SYSTEM IS POSSIBLE AS IT MOVES TOWARD THE NORTH OR NORTH-NORTHEAST AT 5 TO 10 MPH DURING THE NEXT COUPLE OF DAYS. THIS DISTURBANCE HAS A MEDIUM CHANCE…30 PERCENT…OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS. (Invest 91E) Here’s what the weather models are showing for invest 91E

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
