A surface circulation organized quickly inside a low pressure system over the Mozambique Channel on Sunday and the system was designated as Tropical Cyclone 05S.  At 7:00 p.m. EST on Sunday the center or Tropical Cyclone 05S was located at latitude 21.6°N and longitude 39.9°E which put it about 540 miles (870 km) northeast of Maputo, Mozambique.  Tropical Cyclone 05S was moving toward the south-southwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1000 mb.

Tropical Cyclone 05S has a tight center of circulation, but the distribution of thunderstorms is asymmetrical.  Multiple bands of thunderstorms developed in the eastern half of the circulation.  The strongest winds are occurring in the bands of thunderstorms.  However, there are mainly showers and a few isolated thunderstorms in the bands in the western half of the circulation.  The thunderstorms in the bands east of the center of circulation are beginning to generate upper level divergence.

Tropical Cyclone 05S will be moving through a favorable environment during the next several days.  It will be moving over water where the Sea Surface Temperature is near 30°C.  Tropical Cyclone 05S is underneath an upper level ridge.  The upper level winds are weak and there is not much vertical wind shear.  There may be some drier air in the western half of the circulation and that is the only inhibiting factor in the environment around Tropical Cyclone 05S.  Given the mostly favorable environment Tropical Cyclone 05S is likely to intensify during the next day or two.  If an inner core becomes fully developed, then a period of rapid intensification may be possible.

Tropical Cyclone 05S is currently in an area of weak steering currents because of its position underneath the upper level ridge.  Some global models are indicating that a track toward the southwest could be possible if the tropical cyclone moves closer to the western portion of the ridge.  On its anticipated track Tropical Cyclone 05S could move in the general direction of Mozambique.
