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.

Tropical Cyclone Sarai Forms Northwest of Fiji

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.

Tropical Cyclone Mona Turns Back Toward Fiji

Tropical Cyclone Mona turned back toward Fiji on Saturday.  At 10:00 p.m. EST on Saturday the center of Tropical Cyclone Mona was located at latitude 14.9°S and longitude 179.2°E which put it about 250 miles (400 km) north of Suva, Fiji.  Mona was moving toward the east-southeast at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1002 mb.

After being strongly sheared and making a slow clockwise loop on Friday, Tropical Cyclone Mona resumed a course toward Fiji on Saturday.  An upper level trough west of Fiji was producing northwesterly winds which were blowing toward the top of Tropical Cyclone Mona.  Those winds were causing moderate vertical wind shear and they were also causing the distribution of thunderstorms around Mona to be asymmetrical.  The strongest thunderstorms and winds were occurring in bands southeast of the center of circulation.  Bands in the other parts of the circulation consisted primarily of showers and lower clouds.

Tropical Cyclone Mona will move through an environment marginally favorable for intensification during the next 24 hours.  Mona will move over water where the Sea Surface Temperature is near 28°C.  The upper level trough west of Fiji will continue to cause moderate vertical wind shear which will inhibit development.  Tropical Cyclone Mona could strengthen a little bit on Sunday, but it is likely to remain close to its current intensity.

The upper trough will steer Tropical Cyclone Mona toward the south-southeast during the next 12 hours.  The trough is forecast to cutoff and make a transition to an upper low.  The low will steer Mona more toward the south between 12 and 36 hours into the future.  Tropical Cyclone Mona will turn more toward the southwest on Monday.  On its anticipated track the center of Mona will pass near the northeastern end of Vanua Levu in about 12 hours.

Tropical Cyclone Mona will bring wind and rain to Vanua Levu and the eastern islands of Fiji.  Locally heavy rain could cause flash floods in some locations.

Elsewhere, Tropical Cyclone Penny was moving over the Coral Sea back toward Queensland.  At 10:00 p.m. EST on Saturday the center of Tropical Cyclone Penny was located at latitude 17.2°S and longitude 154.8°E which put it about 605 miles (980 km) east of Cairns.  Penny was moving toward the southwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 996 mb.

Tropical Cyclone Mona Forms North of Fiji

Tropical Cyclone Mona formed north of Fiji on Wednesday.  At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Mona was located at latitude 11.6°S and longitude 178.1°E which put it about 460 miles (745 km) north of Suva, Fiji.  Mona was moving toward the south-southeast at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1003 mb.

A distinct low level center of circulation formed within an area of thunderstorms north of Fiji and the Fiji Meteorological Service designated the system as Tropical Cyclone Mona.  The circulation around Tropical Cyclone Mona was still organizing.  There was a small cluster of thunderstorms around the center of circulation.  Bands of showers and thunderstorms were forming and those bands were revolving around the center of circulation.

Tropical Cyclone Mona will move through an environment somewhat favorable for intensification during the next two days.  Mona will move over water where the Sea Surface Temperature is near 29°C.  It will move around the western end of an upper level ridge.  The ridge will produce northerly winds which will cause some vertical wind shear.  The shear will inhibit strengthening, but it will not be strong enough to prevent intensification.  Tropical Cyclone Mona will intensify during the next 36 to 48 hours and it could strengthen into the equivalent of a hurricane/typhoon.

The upper level ridge will steer Tropical Cyclone Mona toward the south-southeast during the next several days.  On its anticipated track Mona could approach Fiji in 36 to 48 hours.  Tropical Cyclone Mona could be the equivalent of a hurricane/typhoon when it nears Fiji.

Elsewhere over the South Pacific Ocean, Tropical Cyclone Penny was reorganizing over the Coral Sea east of Queensland.  At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Penny was located at latitude 14.2°S and longitude 152.2°E which put it about 470 miles (760 km) east-northeast of Cairns, Australia.  Penny was moving toward the east-southeast at 24 m.p.h. (39 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 987 mb.

Tropical Cyclone Keni Brings Winds and Rain to Fiji

Tropical Cyclone Keni brought wind and rain to Fiji on Monday.  At 11:00 p.m. EDT on Monday the center of Tropical Cyclone Keni was located at latitude 19.4°S and longitude 178.0°E which put it about 100 miles (160 km) west-southwest of Suva, Fiji.  Keni was moving toward the east-southeast at 21 m.p.h. (34 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 976 mb.

Tropical Cyclone Keni intensified rapidly on Monday into the equivalent of a hurricane/typhoon.  A primary rainband wrapped tightly around the center of circulation and a small eye formed at the center.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Other bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Keni.  The strongest bands were east and south of the center of circulation.  Storms in the core of Keni were generating upper level divergence which was pumping away mass to the east of the tropical cyclone.  Winds to hurricane/typhoon force extended out about 45 miles (75 km) from the center of circulation.  Winds to tropical storm force extended out about 155 miles (250 km) from the center.

Tropical Cyclone Keni will remain in an environment favorable for intensification for about another 12 to 18 hours.  It will move over water where the Sea Surface Temperature is near 28°C.  Keni is moving under the southwestern portion of an upper level ridge which is producing northwesterly winds which blowing toward the top of the circulation.  Those winds were causing some vertical wind shear, but the shear will not be strong enough to prevent intensification during the next few hours.  Tropical Cyclone Keni will move under strong upper level winds in about 12 to 18 hours and then the wind shear will increase.  Increased wind shear will cause Keni to start to weaken.

The ridge is steering Tropical Cyclone Keni toward the east-southeast and that general motion is expected to continue for another 12 to 18 hours.  An upper level trough approaching from the west will steer Keni more toward the southeast after that time.  On its anticipated track the core and strongest part of Tropical Cyclone Keni will pass southwest of Fiji.  However, clockwise flow around Keni will continue to cause gusty winds and drop heavy rain on Fiji.  The heavy rain could cause flash floods.  Keni could bring wind and rain to Tonga in 18 to 24 hours.

Tropical Cyclone Iris Redevelops East of Queensland.

Tropical Cyclone Iris redeveloped east of Queensland on Sunday night.  At 11:00 p.m. EDT on Sunday the center of Tropical Cyclone Iris was located at latitude 16.9°S and longitude 148.7°E which put it about 190 miles (310 km) east of Cairns, Australia.  Iris was moving toward the southwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 995 mb.

Tropical Cyclone Iris formed over the Coral Sea last week but wind strong vertical shear quickly weakened Iris into an area of low pressure.  The low pressure system meandered over the Coral Sea east of Australia during the past few days.  More thunderstorms developed near the center of circulation on Sunday and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Iris again.

The circulation around Tropical Cyclone Iris was still reorganizing on Sunday night.  A distinct low level center of circulation was evident on visible satellite images.  More thunderstorms were developing near the center.  A primary rainband wrapped around the northern, eastern and southern sides of the center of circulation.  Bands northwest of the center consisted mainly of showers and low clouds.  Storms near the core of the circulation generated upper level divergence which was pumping mass away to the east of the tropical cyclone.

Tropical Cyclone Iris will move through an environment somewhat favorable for intensification on Monday.  Iris will move over water where the Sea Surface Temperature is 29°C.  It is moving around the western end of an upper level ridge.  The ridge is producing northwesterly winds which were blowing toward the top of the circulation.  Those winds were causing moderate vertical wind shear and they may have been the reason for the lack of strong rainbands northwest of the center of circulation.  The wind shear is likely to inhibit intensification, but it probably won’t prevent Tropical Cyclone Iris from intensifying on Monday.

Tropical Cyclone Iris was moving around the western end of a subtropical ridge which was steering Iris toward the southwest.  Iris will likely move more toward the south and then southeast as it rounds the western end of the ridge.  On its anticipated track Tropical Cyclone Iris is expected to remain east of Queensland.

Elsewhere over the South Pacific Ocean Tropical Cyclone Josie was swirling south of Fiji.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Josie was located at latitude 21.1°S and longitude 178.1°E which put it about 185 miles (300 km) south of Suva, Fiji.  Josie was moving toward the south-southeast at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 999 mb.

Tropical Cyclone Josie Brings Wind and Rain to Fiji

Tropical Cyclone Josie brought wind and rain to Fiji on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Cyclone Josie was located at latitude 19.2°S and longitude 177.4°E which put it about 105 miles (170 km) southwest of Suva, Fiji.  Josie was moving toward the east-southeast at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 998 mb.

Tropical Cyclone Josie formed within an area of thunderstorms that had persisted west of Fiji for several days.  A center of circulation developed within the area of thunderstorms and the Fiji Meteorological Service designated the system as Tropical Cyclone Josie.  The circulation of Tropical Cyclone Josie was somewhat asymmetrical.  Most of the stronger thunderstorms were occurring in the eastern half of the circulation.  The strongest winds were occurring in a primary rainband east of the center of circulation,  The bands in the western half of the circulation consisted primarily of showers and lower clouds.  Winds to tropical storm force extended out about 160 miles (260 km) east of the center of circulation.

Tropical Cyclone Josie will move through an area somewhat favorable for intensification during the next day or two.  Josie will move over water where the Sea Surface Temperature is near 28°C.  It will move near an area where westerly winds are blowing in the upper levels and those winds may already be responsible for the asymmetrical distribution of stronger storms.  The upper level winds will cause moderate vertical wind shear, but the shear may not be strong enough to prevent some intensification.  Tropical Cyclone Josie could intensify slowly during the next 24 to 48 hours.

Tropical Cyclone Josie is moving near the eastern end of a ridge which is steering Josie toward the east-southeast.  The westerly winds in the middle troposphere will continue to steer Tropical Cyclone Josie toward the southeast during the next several days.  On its anticipated track the center of Josie will pass south of Viti Levu.  The center of Tropical Cyclone Josie will move near Kadavu and Ono in about 12 hours.  Even though the center of circulation will pass south of Viti Levu, Tropical Cyclone Josie will drop heavy rain there and the potential for flash floods will exist.  Josie will also bring gusty winds and heavy rain to Kadavu and Ono.
