Tropical cyclone activity continues worldwide!

Tropical cyclone activity continues unabated in the northern hemisphere. More than sixty named-storms have been generated worldwide so far in 2018 in the northern  hemisphere, from the Atlantic, the Pacific (east, central, and northwest basins), to the Indian ocean.

Large and powerful super-typhoon TRAMI continues its approach toward Taiwan over the northwest Pacific

Currently super-typhoon TRAMI continues to move toward Taiwan, while other large tropical waves and disturbed weather cells are active over the Northwest Pacific.

In the East Pacific basin hurricane ROSA, the 18th named storm of the 2018 season is active off the coast of Mexico. Other potentially cyclonic systems are on the move off the coast of Central America and Panama.

Satellite image (NOAA) of 26 September 2018 showing various storms systems over the Atlantic basin, including a regenerated KIRK, now a tropical storm, a degrading LESLIE, and other potentially cyclonic systems near the Carolinas’ coast and in ‘Hurricane Alley” and Equatorial Africa.

In the Atlantic, KIRK has regenerated into a tropical storm to the east of Barbados, while LESLIE now a tropical depression is approaching the region of the Azores Islands. Another disturbed weather system is off the coast of the Carolinas to the south of Cape Hatteras, which warrants monitoring. Other tropical waves extend from ‘Hurricane Alley’ to Equatorial Africa.

Following the Autumn equinox the Sun above is now to the south of the equator increasing the heat content of the world’s oceans. As a result, we are beginning to detect some potential for cyclonic development in the southern hemisphere. One such system is now being monitored near Australia’s northeast coast.

There is plenty of fuel for continued tropical cyclone generation worldwide this Wednesday 26 September 2018. Vulnerable communities everywhere will do well to remain alert. Be prepared! MITIGATE!

26 July 2018: What’s happening in the Atlantic hurricane-wise?

The initial round of predictions for the 2018 Atlantic Hurricane Season called for “above average” activity in the basin.  That forecast was downgraded  during subsequent rounds of ‘revised’ predictions,  mainly because of an incipient ENSO signal off the pacific coast of Peru, which may generate a somewhat adverse environment for cyclogenesis over the Atlantic. Of course Mother Nature will do as she pleases, so we’ll have to wait and see what actually happens during the remaining 127 days of the ‘official’ Atlantic season.

Although the season got an early start with Alberto in May, and two other named-storms, Beryl and Chris have activated and lived in the Atlantic since, but things have been somewhat quiet lately. On this Thursday 26 July 2018 satellite imagery shows a largely calm ocean-atmospheric environment over most of the Atlantic basin, except for a train of minor tropical waves and disturbed weather cells riding along Hurricane Alley between the Atlantic coast of Africa and the Windward Islands, the gate to the Caribbean.

Looking farther east through Equatorial Africa there are a few tropical waves moving westward along the assembly lane, but nothing that causes concerns for possible tropical cyclone activity over the next few day, at least. So all we can do is watch and wait as we start to approach what historically has been the most active part of the Atlantic season from around mid-August through early October.

Elsewhere tropical cyclone activity has been quite active at both extremes of the northern hemisphere Pacific Ocean, with numerous storms and tropical waves hitting over the East Pacific off the coast of Central America and Mexico and near Hawaii, as well as over the Northwest Pacific and sub-basins of the Philippines Sea, and South China Sea. The Philippines, Taiwan, Viet Nam, China, South Korea, and Japan have all suffered hits, some of them more than once, from tropical storms and typhoons in 2018.

On this 26 July satellite imagery shows two tropical storms,  Jongdari and Wukong, moving toward potential landfalls in south-central as well as northern Japan, while some 11000 kilometers to  the east over the East Pacific we are tracking two strong tropical waves between Mexico and Hawaii, which are showing some tendency toward possible cyclonic activity.
