Tropical Cyclone Sarai formed northwest of Fiji on Thursday.  At 10:00 a.m. EST on Thursday the center of Tropical Cyclone Sarai was located at latitude 14.9°S and longitude 175.8°E which put it about 220 miles (355 km) north-northwest of Nadi, Fiji.  Sarai was moving toward the south at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 995 mb.

The circulation around a low pressure system northwest of Fiji exhibited greater organization on Thursday and the Fiji Meteorological Service designated the system as Tropical Cyclone Sarai.  The circulation around Tropical Cyclone Sarai was still organizing.  A band of showers and thunderstorms wrapped around the southern and western sides of the center of circulation.  Other bands of showers and thunderstorms were developing and the bands were starting to revolve around the center.  Storms near the center were generating upper level divergence which was pumping mass away from the tropical cyclone.  The circulation around Tropical Cyclone Sarai was large.  Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation.

Tropical Cyclone Sarai will move through an environment favorable for intensification during the next 48 hours.  Sarai will move over water where the Sea Surface Temperature is near 28°C.  It will move under the western end of an upper level ridge.  The ridge will produce northerly winds which will blow toward the top of the circulation.  However, there will be northerly winds at most levels of the troposphere, which means that there will not be a lot of vertical wind shear.  Tropical Cyclone Sarai will intensify during the next 36 to 48 hours and it could strengthen into the equivalent of a hurricane/typhoon.

Tropical Cyclone Sarai will move around the western end of a subtropical high pressure system over the South Pacific Ocean.  The high will steer Sarai toward the south during the next 24 hours.  Tropical Cyclone Sarai will turn more toward the east in a day or so when it rounds the end of the ridge.  On its anticipated track the center of Sarai could approach western Fiji in 24 to 36 hours.
