Tropical Cyclone Rae Brings Wind and Rain to Eastern Fiji

Tropical Cyclone Rae brought wind and rain to eastern Fiji on Sunday night.  At 7:00 p.m. EST on Sunday the center of Tropical Cyclone Rae was located at latitude 18.2°S and longitude 179.4°W which put the center about 55 miles (90 km) east-northeast of Moala, Fiji.  Rae was moving toward the south-southwest at 11 m.p.h. (17 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 988 mb.

Tropical Cyclone Rae brought strong winds and heavy rain to parts of eastern Fiji on Sunday night.  Rae passed over the Lau Group of islands.  The center of Tropical Cyclone Rae passed near Naitaba, Vanna Balavu, Mago, and Cicia.

Tropical Cyclone Rae intensified as it passed over eastern Fiji.  The inner end of a rainband wrapped around the center of Rae’s circulation.  An eye formed at the center of Tropical Cyclone Rae.  A ring thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Rae.  Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone.

The circulation around Tropical Cyclone Rae became more circular on Sunday.  Winds to tropical storm force extended out 140 miles (225 km) from the center of Rae’s circulation.

Tropical Cyclone Rae will move through an environment favorable for intensification during the next 24 hours.  Rae will move over water where where the Sea Surface Temperatures are near 28°C.  It will move under the middle of an upper level ridge near Fiji. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Cyclone Rae is likely to intensify to the equivalent of a hurricane/typhoon during the next 24 hours.

Tropical Cyclone Rae will move around the western end of a high pressure system over the South Pacific Ocean.  The high pressure system will steer Rae toward the south during the next 24 hours.  On its anticipated track, Tropical Cyclone Rae will move over the southern islands of in the Lau Group.

Tropical Cyclone Rae will bring continue to bring strong winds and heavy rain to the Lau Group of islands.  The center of center of Rae’s circulation will pass near Moala, Totoya, and Mataku.  Heavy rain is likely to cause flash floods in some locations.

Tropical Cyclone Rae Forms Northeast of Fiji

Tropical Cyclone Rae formed northeast of Fiji on Sunday.  At 4:00 a.m. EST on Sunday the center of Tropical Cyclone Rae was located at latitude 15.8°S and longitude 178.9°W which put the center about 200 miles (325 km) northeast of Suva, Fiji.  Rae was moving toward the south-southwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 989 mb.

A low pressure system over the South Pacific Ocean strengthened on Sunday and the Fiji Meteorological Service designated the system as Tropical Cyclone Rae.  The circulation around Tropical Cyclone Rae was organizing rapidly on Sunday.  More thunderstorms developed near the center of Tropical Cyclone Rae.  More thunderstorms also formed in the bands revolving around the center of Rae’s circulation.  Storms near the center of Rae generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Cyclone Rae became more symmetrical on Sunday.  Winds to tropical storm force extended out 180 miles (290 km) from the center of Rae’s circulation.

Tropical Cyclone Rae will move through an environment favorable for intensification during the next 24 hours.  Rae. will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge near Fiji. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Tropical Cyclone Rae will intensify during the next 24 hours.

Tropical Cyclone Rae will move around the western end of a high pressure system over the South Pacific Ocean.  The high pressure system will steer Rae toward the south during the next 24 hours.  On its anticipated track, Tropical Cyclone Rae will move over the islands of eastern Fiji.  The center of Rae’s circulation will pass east of Vanua Levu.

Tropical Cyclone Rae will bring strong winds and heavy rain to the Lau Group of islands.  The center of center of Rae’s circulation could pass near Vanna Balavu.  Heavy rain could cause flash floods in some locations.

Severe Tropical Cyclone Yasa Hits Fiji

Severe Tropical Cyclone Yasa hit Fiji early on Thursday. At 4:00 a.m. EST on Thursday the center of Tropical Cyclone Yasa was located at latitude 16.8°S and longitude 179.2°E which put it about 30 miles (50 km) south of Naduri, Fiji. Yasa was moving toward the east-southeast at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h). The minimum surface pressure was 922 mb.

The eye of Tropical Cyclone Yasa made landfall in Fiji on Vanua Levu west of Naduri early on Thursday. Yasa was a large, powerful tropical cyclone when it hit Fiji. Tropical Cyclone Yasa was the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale at the time of landfall. Winds to hurricane/typhoon force extended out 65 miles (105 km) from the center of Yasa. Winds to tropical storm force extended out 200 miles (320 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Yasa was 31.6. The Hurricane Size Index (HSI) was 23.1 and the Hurricane Wind Intensity Size Index (HWISI) was 54.7. Yasa was capable of causing severe damage.

Tropical Cyclone Yasa brought destructive winds to Vanua Levu when the core of the circulation passed over that island. Severe wind damage was likely. Yasa was capable of causing a storm surge of up to 15 feet (5 meters) on the north coast of Vanua Levu. It was also dropping heavy rain and flash floods were likely. Bands in the western half of Tropical Cyclone Yasa caused strong winds and heavy rain over the eastern part of Viti Levu. Widespread power outages were likely.

Tropical Cyclone Yasa will move toward the southeast over the islands in the Lau Group later on Thursday. Yasa will weaken as it crosses Vanua Levu, but it will still be a strong tropical cyclone. Tropical Cyclone Yasa could cause serious wind damage and cause flash floods on many of the islands in the Lau Group.

Tropical Cyclone Sarai Moves Across Southern Fiji

Tropical Cyclone Sarai moved across southern parts of Fiji on Saturday.  At 10:00 p.m. EST on Saturday the center of Tropical Cyclone Sarai was located at latitude 19.9°S and longitude 179.1°E which put it about 30 miles (50 km) southwest of Matuku, Fiji.  Sarai was moving toward the east at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (155 km/h).  The minimum surface pressure was 976 mb.

Tropical Cyclone Sarai strengthened into the equivalent of a hurricane/typhoon on Saturday as it moved across the southern part of Fiji.  The center of Sarai passed south of Kadavu, but raindbands on the northern side of the circulation brought gusty winds and heavy rain to the island.  A ragged eye appeared intermittently on satellite images.  The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Tropical Cyclone Sarai had a large circulation.  Winds to hurricane/typhoon force extended out 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out 200 miles (320 km) from the center.

Tropical Cyclone Sarai will move into an environment that will become increasingly unfavorable for intensification.  Sarai will move over water where the Sea Surface Temperature is near 28°C.  So, there will be enough energy in the upper ocean to support a strong tropical cyclone.  Tropical Cyclone Sarai will move south of an upper level ridge.  The ridge will produce westerly winds which will get stronger during the next several days.  Those winds will cause moderate vertical wind shear.  When the shear gets stronger, Tropical Cyclone Sarai will start to weaken.

Tropical Cyclone Sarai will move south of a subtropical high pressure system over the South Pacific Ocean.  The high will steer Sarai toward the east during the next 48 hours.  On its anticipated track Tropical Cyclone Sarai will move across Matuku, Fiji during the next few hours.  Sarai will reach the Lau Group of Fiji Islands during the next 24 hours.  Tropical Cyclone Sarai could reach parts of Tonga within 48 hours.  Sarai will bring gusty winds and heavy rain to all of those places during the next 48 hours.
