Located in a favorable environment consisting of low wind shear and warm sea surface temperatures Benita continued to strengthen, gaining hurricane strength the next day on January 26 as an eye developed inside a central dense overcast. Danette quickly fizzled out over land and became a remnant low on March 5 and dissipating completely six hours later. As the system began to turn to the north and east it regained tropical storm intensity as convection re-established over the center of the storm. Only three tropical cyclones are known to have formed in the Southern Atlantic Ocean, the most recent of which was Tropical Storm Anita in 2010.

There are hurricanes in the south Atlantic, only that we may call it something different. Early on December 23 the system became organized enough to become Tropical Depression Two-Q. During the next couple of days convection began to develop over the low pressure center of the cyclone while detaching from its frontal systems. During the afternoon of December 22 an area of low pressure exited the eastern coast of South America. In meteorology, a hurricane is the name given to any wind force in excess of force 12 in the Beaufort scale or, superior to 64 knots.

There are no tropical cyclones in the Atlantic at this time. Over the next four days it moved towards southern Africa with it making landfall on December 31 at minimal tropical storm intensity. Later that day the depression began to move into an area of higher wind shear and decreasing sea surface temperatures which caused it to begin weakening. Forecasters at NOAA’s National Hurricane … The storm fell to tropical depression status by the next advisory as land interaction took its toll on the system, despite weakening to a tropical depression quickly it persisted at that strength for a day before degenerating to a remnant low pressure and dissipated completely twelve hours later.

The South Atlantic off the east coast of Brazil isn’t favorable for hurricanes for a variety of reasons, including prevalent wind shear (variation of wind speed or direction at different altitudes.) Eben began to undergo an extratropical transition on March 19 with the convection diminishing and what was left titling back with height.

On February 16 an extratropical cyclone located off of Namibia began to exhibit signs of transitioning into a subtropical cyclone as convection started to increase near the center of circulation and lose its frontal systems. The subtropical cyclone began to have convection flare up closer to the center of circulation and became fully tropical twelve hours later while approaching the coast of Angola. Eben continued to strengthen reaching category two strength while moving to the west. Shortly before the hurricane would make landfall the system weakened to a tropical storm.
