Tropical Cyclone Sarai Brings Wind and Rain to Fiji

Tropical Cyclone Sarai brought wind and rain to Fiji in Friday.  At 4:00 p.m. EST on Friday the center of Tropical Cyclone Sarai was located at latitude 19.3°S and longitude 177.0°E which put it about 100 miles (160 km) west-southwest of Kadavu, Fiji.  Sarai was moving toward the southeast at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 983 mb.

The center of Tropical Cyclone Sarai passed west of Nadi, Fiji on Friday, but rainbands in the eastern side of the circulation produced gusty winds and heavy rain.  A surface weather station in Nadi measured a sustained wind speed of 44 m.p.h. (70 km/h) and wind gusts of 67 m.p.h. (107 km/h).

Tropical Cyclone Sarai continued to intensify on Friday.  The inner end of a rainband wrapped much of the way around the center of circulation.  The rainband had not wrapped entirely around the northwestern part of the center,  A clear area at the center began to appear on satellite images, which could be evidence of formation of an eye.  Storms around the center were generating upper level divergence which was pumping mass away to the east of the tropical cyclone.  The circulation around Tropical Cyclone Sarai was large.  Winds to tropical storm force extended out 200 miles (320 km) from the center of Sarai.

Tropical Cyclone Sarai will move through an environment favorable for intensification for another 24 to 36 hours.  Sarai will move over water where the Sea Surface Temperature is near 28°C.  It will move south of an upper level ridge.  The ridge will produce westerly winds which will blow toward the top of the circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification, but it will not be strong enough to keep Tropical Cyclone Sarai from strengthening into the equivalent of a hurricane/typhoon.

Tropical Cyclone Sarai will move south of a subtropical high pressure system over the South Pacific Ocean.  The ridge will steer Sarai toward the east.  On its anticipated track the center of Tropical Cyclone Sarai will pass south of Suva, Fiji.  The core of Sarai will pass near Kadavu, Fiji in about 12 to 18 hours.  Tropical Cyclone Sarai will bring gusty winds and locally heavy rain to Kadavu.  Heavy rain could cause flash floods in some locations.
