Tropical Cyclone Cilida formed north of Mauritius on Wednesday.  At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Cilida was located at latitude 12.2°S and longitude 59.8°E which put it about 585 miles (945 km) north-northeast of Port Louis, Mauritius.  Cilida was moving toward the southwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 55 m.p.h. (90 km/h) and there were wind gusts to 70 m.p.h. (110 km/h).  The minimum surface pressure was 989 mb.

The circulation around Tropical Cyclone Cilida organized quickly on Wednesday. A small circular eye formed at the center of circulation.  A ring of strong thunderstorms formed around the eye and the strongest winds were occurring in that ring of storms.  A strong band of storms wrapped around the western and northern sides of Cilida.  Other bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Cilida.  Winds to tropical storm force extended out about 100 miles (160 km) from the center of circulation.

Tropical Storm Cilida will move through an environment favorable for intensification during the next 48 to 72 hours.  Cilida will move over water where the Sea Surface Temperature is near 27°C.  It will move through an area where the upper level winds are weak and there will be little vertical wind shear.  Cilida is likely to strengthen into the equivalent of a hurricane/typhoon on Thursday and it could intensify rapidly.  Tropical Cyclone Cilida could intensify into the equivalent of a major hurricane in two or three days.

Tropical Cyclone Cilida will move around the western end of a subtropical ridge.  The ridge will steer Cilida toward the south during the next several days.  On its anticipated track Tropical Cyclone Cilida could approach Mauritius from the north in about 48 hours.

Elsewhere over the South Indian Ocean Tropical Cyclone Kenanga drifted southeast of Diego Garcia.  At 10:00 p.m. EST on Wednesday the center Tropical Cyclone Kenanga was located at latitude 16.5°S and longitude 81.9°E which put it about 910 miles (1470 km) southeast of Diego Garcia.  Kenanga was stationary.  The maximum sustained wind speed was 125 m.p.h. (205 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 947 mb.
