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!

HURRICANE SEASON 2018: THE ATLANTIC WAKES UP!

Earlier this year predictions called for a rather active 2018 Atlantic Hurricane season, but as an incipient ENSO began to show off the Pacific coast of Peru and Ecuador and other contributing factors became evasive, predictions were changed to a “somewhat below average” to “average” season, whatever “average” means.

The reality of tropical cyclone activity in 2018 in the Earth’s northern hemisphere is that while the Northwest Pacific has already seen 23 named-storms, some of them ferocious category 5 cyclones, and the East Pacific is already up to 15 named-storm, the Atlantic basin has been somewhat quiet with  barely six named-storm by early September until FLORENCE, number 7, appeared over the eastern Atlantic but soon encountered an adverse ocean-atmosphere environment and wind shear, which weakened considerably putting in doubt its future progress.

As of today all of that has changed, FLORENCE is regaining strength and may possibly become a major hurricane as it continues to move toward the Carolinas on the east coast, while two other tropical storms HELENE and ISAAC have formed over the far eastern Atlantic. At the same time, a low pressure system moves over Bermuda ahead of Florence, and a menacing looking tropical wave over equatorial Africa continues moving westward toward the Atlantic just south of the Cape Verde islands, and a large cell of disturbed weather is on the march in the Caribbean. So, as of this Saturday 8 September we have reached nine named-storm and there is plenty of fuel for additional cyclonic activity in the Atlantic basin.

Projected track of FLORENCE as of 8 September 2018

All interests in and around the north Atlantic basin must monitor these named tropical cyclones closely over the next few days, and be on the alert for other potential cyclonic activity in days to come. Be prepared! MITIGATE!

Projected Hurricane OLIVIA as of 8 September 2018 has it aiming for Hawaii

Elsewhere, hurricane OLIVIA appears to be aiming for Hawaii, which is still recovering from the brush with LANE just a couple of weeks ago. Farther to the west, Typhoon MANGKHUT is moving over the northwest Pacific in the general direction of the northern Philippines, Taiwan, and Japan. This is a region that has already seen several landfalling tropical cyclones causing plenty of damage and human suffering.
