Tropical Cyclone Irene Forms West of Vanuatu

Tropical Cyclone Irene formed over the South Pacific Ocean west of Vanuatu on Wednesday morning. At 10:00 a.m. EST on Wednesday the center of Tropical Cyclone Irene was located at latitude 18.7°S and longitude 166.3°E which put it about 320 miles (520 km) west-southwest of Port Vila, Vanuatu. Irene was moving toward the east at 21 m.p.h. (33 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 990 mb.

An area of low pressure over the South Pacific Ocean strengthened rapidly on Wednesday morning and the Fiji Meteorological Service designated the system as Tropical Cyclone Irene. The inner end of a rainband wrapped around the western and southern side of Irene’s circulation. Other bands of thunderstorms were occurring in the eastern half of Tropical Cyclone Irene. Bands in the western half of the circulation consisted primarily of showers and lower clouds. Storms near the center of circulation generated upper level divergence that pumped mass away to the southeast of the tropical cyclone. Winds to tropical storm force extended out 115 miles (185 km) from the center of Irene.

Tropical Cyclone Irene will move through an environment favorable for intensification during the next 24 hours. Irene will move over over water where the Sea Surface Temperatures are near than 28˚C. An upper level trough east of Australia will produce northwesterly winds that will blow toward the top of Irene’s circulation. Those winds will cause vertical wind shear, but the wind shear will not be strong enough to prevent intensification. Tropical Cyclone Irene is likely to intensify during the next 24 hours. It could intensify rapidly during the next 12 hours. Irene could strengthen to the equivalent of a hurricane/typhoon.

The upper level trough east of Australia will steer Tropical Cyclone Irene quickly to the east-southeast during the next 24 hours. The center of Irene could pass near the southern islands of Vanuatu in 12 hours. The center of Tropical Cyclone Irene will be near Tanna and Aneityum in 12 hours. Irene could bring strong gusty winds and locally heavy rain to southern Vanuatu. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Gina Moves over Vanuatu

Tropical Cyclone Gina moved over Vanuatu on Thursday. At 5:00 p.m. EDT on Thursday the center of Tropical Cyclone Gina was located at latitude 17.4°S and longitude 168.4°E which put it about 35 miles (55 km) north-northwest of Port Vila, Vanuatu. Gina was moving toward the south-southwest at 5 m.p.h (8 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.

The center of Tropical Cyclone Gina moved over southern Vanuatu on Thursday. The distribution of thunderstorms around Gina’s circulation continued to be asymmetrical. The strongest thunderstorms were occurring in bands in the southeastern part of Tropical Cyclone Gina. Heavy rain fell on Efate. Bands in the other parts of Gina’s circulation consisted primarily of showers and lower clouds. An upper level trough over the Coral Sea continued to produce northwesterly winds that were blowing toward the top of Tropical Cyclone Gina. Those winds were still causing moderate vertical wind shear and the wind shear was contributing to the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 50 miles (80 km) from the center of Gina’s circulation.

Tropical Cyclone Gina will move through an environment that is only marginally favorable for intensification during the next 36 hours. Gina will move over water where the Sea Surface Temperatures are near 27˚C. However, the upper level trough over the Coral Sea will continue to produce northwesterly winds that will cause moderate vertical wind shear. The wind shear will strongly inhibit intensification. Tropical Cyclone Gina could maintain its intensity during the next 36 hours, if the upper level winds do not get stronger. If the wind shear increases, then Gina could weaken.

Tropical Cyclone Gina will move around the northwestern part of a high pressure system over the South Pacific Ocean during the next 26 hours. The high pressure system will steer Gina toward the southwest. On its anticipated track the center of Tropical Cyclone Gina will move southwest of Vanuatu during the next 36 hours. Gina could be northeast of New Caledonia during the weekend. Heavy rain could continue to fall over Efate during the next 12 to 18 hours. Rain should end on Friday when Tropical Cyclone Gina moves away from Vanuatu.

Tropical Cyclone Gina Forms East of Vanuatu

Tropical Cyclone Gina formed over the South Pacific Ocean east of Vanuatu on Wednesday. At 5:00 p.m. EDT on Wednesday the center of Tropical Cyclone Gina was located at latitude 15.3°S and longitude 168.9°E which put it about 190 miles (305 km) north-northeast of Port Vila, Vanuatu. Gina was moving toward the west at 4 m.p.h (6 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.

A low pressure system over the South Pacific Ocean east of Vanuatu strengthened on Wednesday and the Fiji Meteorological Service designated the system as Tropical Cyclone Gina. The low level center of Tropical Cyclone Gina was located east of Maewo and northeast of Pentecost. The distribution of thunderstorms around Gina’s circulation was asymmetrical. The strongest thunderstorms were occurring in bands in the southeastern part of Tropical Cyclone Gina. Bands in the other parts of Gina’s circulation consisted primarily of showers and lower clouds. An upper level trough over the Coral Sea was producing northwesterly winds that were blowing toward the top of Tropical Cyclone Gina. Those winds were causing moderate vertical wind shear and the wind shear was contributing to the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 60 miles (95 km) from the center of Gina’s circulation.

Tropical Cyclone Gina will move into an environment that is only marginally favorable for intensification during the next 24 hours. Gina will move over water where the Sea Surface Temperatures are near 27˚C. However, the upper level trough over the Coral Sea will continue to produce northwesterly winds that will cause moderate vertical wind shear. The wind shear will strongly inhibit intensification. Tropical Cyclone Gina could strengthen a little during the next 24 hours, if the upper level winds weaken slightly. If the wind shear increases, then Gina could weaken.

Tropical Cyclone Gina will move around the northwestern part of a high pressure system over the South Pacific Ocean during the next 24 hours. The high pressure system will steer Gina toward the southwest. On its anticipated track the center of Tropical Cyclone Gina will move across Pentecost during the next 12 hours. The center of Gina could pass just north of Ambrym and it could move across Malekula within 24 hours. Since the strongest thunderstorms are in the southeastern part of Tropical Cyclone Gina, the gustiest winds and heaviest rain could affect Efate and Port Vila. Heavy rain could cause flash floods in some locations.

Tropical Cyclone May Develop Northeast of Vanuatu

A tropical cyclone may develop over the South Pacific Ocean northeast of Vanuatu during the next several days. At 2:00 p.m. EDT on Monday the center of a low pressure system, also designated at Invest 91P, was located at latitude 13.5°S and longitude 171.7°E which put it about 375 miles (600 km) northeast of Port Vila, Vanuatu. The low pressure system was moving toward the south-southwest at 4 m.p.h (6 km/h). The maximum sustained wind speed was 20 m.p.h. (30 km/h) and there were wind gusts to 30 m.p.h. (50 km/h). The minimum surface pressure was 1010 mb.

More thunderstorms formed just to the southwest of the center of a low pressure system over the South Pacific Ocean northeast of Vanuatu on Monday. Thunderstorms also formed in bands revolving around the center of the low pressure system. The storms just southwest of the center of circulation began to generate upper level divergence that started to pump mass away from the low pressure system. The better organization exhibited by the low pressure system increased the potential that the low may develop into a tropical cyclone during the next several days.

The low pressure system will move into an environment that is favorable for the development of a tropical cyclone. The low pressure system will move over water where the Sea Surface Temperatures are near 27˚C. It will move under the western side of an upper level ridge over the South Pacific Ocean. The ridge will produce northerly winds that will blow toward the top of the low pressure system. Those winds will cause some vertical wind shear, but the shear will not be great enough to prevent intensification. The low pressure system could strengthen to a tropical cyclone during the next several days.

The low pressure system will move around the western end of a high pressure system over the South Pacific Ocean. The high pressure system will steer the low pressure system toward the south-southwest during the next several days. On its anticipated track the low pressure system could approach southern Vanuatu later this week.

Tropical Cyclone Dovi Brings Wind and Rain to Vanuatu

Tropical Cyclone Dovi brought wind and rain to parts of Vanuatu on Wednesday morning. At 10:00 a.m. EST on Wednesday the center of Tropical Cyclone Dovi was located at latitude 20.5°S and longitude 169.4°E which put it about 260 miles (420 km) east-northeast of Noumea, New Caledonia. Dovi was moving toward the southeast at 6 m.p.h. (10 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 991 mb.

Tropical Cyclone Dovi brought gusty winds and rain to southern Vanuatu on Wednesday morning. The center of Dovi’s circulation was southwest of Aneityum. Bands on the northern side of Tropical Cyclone Dovi also brought wind and rain to Erromango and Tanna. The inner end of a rainband wrapped around the center of Dovi’s circulation, which could represent the initial stage in the formation of an eyewall. Most of the thunderstorms and the strongest winds were occurring in bands in the northern half of Tropical Cyclone Dovi. Bands in the southern half of the circulation consisted primarily of showers and lower clouds. Storms near the center generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 175 miles (280 km) in the northern half of Dovi’s circulation. Winds to tropical storm force extended out 70 miles (110 km) in the southern half of the circulation.

Tropical Cyclone Dovi will move through an environment favorable for intensification during the next 24 hours. Dovi will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the western part of an upper level ridge centered east of New Caledonia. The ridge will produce southerly winds that will blow toward the top of the tropical cyclone. Those winds will some moderate vertical wind shear. The wind shear will inhibit intensification, but it will not be strong enough to prevent intensification. Tropical Cyclone Dovi will intensify during the next 24 hours and it could strengthen rapidly if an inner core with an eye and an eyewall devlops.

Tropical Cyclone Dovi will move around the western side of a high pressure system over the South Pacific Ocean. The high pressure system will steer Dovi toward the southwest during the next 24 hours. On its anticipated track Tropical Cyclone Dovi will move slowly away from Vanuatu. Weather conditions will gradually improve as Dovi moves away. Tropical Cyclone Dovi will be near the Loyalty Islands in 12 hours. The center could pass near Mare. Dovi will bring gusty winds and locally heavy rain to Ouvea, Lifou and Mare. The center of Tropical Cyclone Dovi could be near Ile des Pins in 24 hours. Dovi will begin to affect southern New Caledonia during the next 24 hours.

Tropical Cyclone Forms near Vanuatu

Tropical Cyclone 11P formed near Vanuatu on Tuesday night. At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone 11P was located at latitude 19.8°S and longitude 168.9°E which put it about 235 miles (380 km) northeast of Noumea, New Caledonia. Tropical Cyclone 11P was moving toward the south-southeast at 4 m.p.h. (6 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 994 mb.

A low pressure system near the island of Tanna strengthened to a tropical cyclone on Tuesday night. More thunderstorms developed in bands in the western half of Tropical Cyclone 11P. Bands in the eastern half of the circulation consisted primarily of showers and low clouds. Storms near the center of circulation began to generate upper level divergence that pumped mass away to the west of the tropical cyclone. Winds to tropical storm force extended out 75 miles (120 km) from the center of circulation.

Tropical Cyclone 11P will move through an environment favorable for intensification during the next 24 hours. Tropical Cyclone 11P will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the northern part of an upper level ridge centered east of New Caledonia. The ridge will produce southeasterly winds that will blow toward the top of the tropical cyclone. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but it will not be strong enough to prevent intensification. Tropical Cyclone 11P is likely to intensify during the next 24 hours.

Tropical Cyclone 11P will move around the western side of a high pressure system over the South Pacific Ocean. The high pressure system will steer the tropical cyclone toward the south-southwest during the next 24 hours. On its anticipated track Tropical Cyclone 11P will move slowly away from Vanuatu. The tropical cyclone will be near the Loyalty Islands in 24 hours. The center could pass near Mare. Tropical Cyclone 11P will bring gusty winds and locally heavy rain to Ouvea, Lifou and Mare. The center of Tropical Cyclone could reach southern New Caledonia within 36 hours.

Tropical Cyclone Tiffany Strengthens East of Cape York Peninsula

Tropical Cyclone Tiffany strengthened east of the Cape York Peninsula on Sunday morning. At 7:00 a.m. EST on Sunday the center of Tropical Cyclone Tiffany was located at latitude 13.9°S and longitude 145.9°E which put it about 120 miles (190 km) north-northeast of Cooktown, Australia. Tropical Cyclone was moving toward the west at 9 m.p.h. (14 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 990 mb.

A Warning was in effect for the portion of the east coast of the Cape York Peninsula from Cape Grenville to Cape Tribulation. A Watch was in effect for the west coast of the Cape York Peninsula from Gilbert River Mouth to Mapoon.

A former Tropical Low east of the Cape York Peninsula strengthened quickly on Sunday morning and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Tiffany. More Thunderstorms developed near the center of Tiffany’s circulation. More thunderstorms also formed in bands revolving around the center of Tropical Cyclone Tiffany. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 70 miles (110 km) from the center of Tiffany.

Tropical Cyclone Tiffany will move through an environment favorable for intensification during the next 12 hours. Tiffany will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the northwestern part of an upper level ridge centered east of Australia. The ridge will produce easterly winds that will blow toward the top of the Tropical Low’s circulation. Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification. The center of Tropical Cyclone Tiffany will pass near Cape Melville in 12 hours. If some of the circulation on the southern side of Tiffany passes over land, that could inhibit intensification.

Tropical Cyclone Tiffany will move north of a high pressure system over Australia. The high pressure system will steer Tiffany toward the west during the next 36 hours. On its anticipated track the center of Tropical Cyclone Tiffany will pass just north of Cape Melville in 12 hours. Tiffany will make landfall on the east coast of the Cape York Peninsula east of Coen within 24 hours. Tropical Cyclone Tiffany will bring gusty winds and locally heavy rain to northern Queensland. Heavy rain is likely to cause flash floods in some locations.

Elsewhere over the South Pacific Ocean, Tropical Cyclone 05P was spinning between Fiji and Vanuatu. At 4:00 a.m. EST on Sunday the center of Tropical Cyclone 05P was located at latitude 18.9°S and longitude 176.3°E which put it about 150 miles (240 km) west of Tavuki, Fiji. Tropical Cyclone 05P was moving toward the east-southeast at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1000 mb.

Two Tropical Lows Form over South Pacific

Two tropical lows formed over the South Pacific Ocean on Saturday morning. The first Tropical Low formed over the Coral Sea east of the Cape York Peninsula. At 7:00 a.m. EST on Saturday the center of that Tropical Low was located at latitude 13.0°S and longitude 147.8°E which put it about 240 miles (350 km) northeast of Cooktown, Australia. The Tropical Low was nearly stationary. The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1004 mb.

A well defined low level center of circulation formed in a small low pressure system over the Coral Sea on Saturday morning and the Australian Bureau of Meteorology designated the system as a Tropical Low. A Watch was issued for the portion of the east coast of the Cape York Peninsula from Cape Grenville to Cape Tribulation. The distribution of thunderstorms around the Tropical Low was asymmetrical. The distribution of thunderstorms around the Tropical Low was asymmetrical. The strongest thunderstorms were occurring in bands in the northwestern quadrant of the circulation. Bands in other parts of the circulation consisted primarily of showers and lower clouds. Storms near the center began to generate upper level divergence that pumped mass away from the Tropical Low.

The Tropical Low will move through an environment somewhat favorable for intensification during the next 24 hours. The Tropical Low will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the northwestern part of an upper level ridge centered east of Australia. The ridge will produce easterly winds that will blow toward the top of the Tropical Low’s circulation. Those winds will cause some vertical wind shear and the shear will inhibit intensification. The Tropical Low could intensify gradually during the next 24 hours.

The Tropical Low will move north of a high pressure system centered east of Australia. The high pressure system will steer the Tropical Low toward the west during the next 24 hours. On its anticipate track the Tropical Low could approach the eastern Cape York Peninsula between Lockhart River and Cooktown in 36 hours. It could be a named tropical cyclone when it approaches the coast.

The second Tropical Low developed over the South Pacific Ocean west of Fiji. At 10:00 a.m. EST on Saturday the center of the second Tropical Low was located at latitude 18.6°S and longitude 173.3°E which put it about 320 miles (515 km) west-southwest of Nadi, Fiji. That Tropical Low was moving toward the southeast at 4 m.p.h. (6 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 1000 mb.

A distinct low level center of circulation developed in a large low pressure system over the South Pacific Ocean west of Fiji and the Fiji Meteorological Service designated the system as a tropical low. The circulation around the second Tropical Low was much larger than the one over the Coral Sea, but the distribution of thunderstorms was also asymmetrical. The strongest thunderstorms were occurring in bands north and east of the center of circulation. Bands south and west of the center consisted primarily of showers and lower clouds. Storms near the center generated upper level divergence that pumped mass away from Tropical Low.

The second Tropical Low will move through an environment favorable for intensification during the next 24 hours. The Tropical Low will move over water where the Sea Surface Temperatures are near 30˚C. It will move through an area where the upper level winds are weak and there will be little vertical wind shear. The Tropical Low is likely to intensify into a named tropical cyclone during the next 24 hours.

The second Tropical Low will be in an area where the steering currents are weak during the next 24 hours. It is likely to meander slowly over the South Pacific Ocean between Fiji and Vanuatu during the next day or so.

Tropical Cyclone Bina Develops Northwest of Fiji

Tropical Cyclone Bina developed northwest of Fiji on Sunday. At 10:00 a.m. EST on Sunday the center of Tropical Cyclone Bina was located at latitude 14.0°S and longitude 175.7°E which put it about 315 miles (510 km) northwest of Labasa, Fiji. Bina was moving toward the southeast at 16 m.p.h. (26 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 994 mb.

As Tropical Cyclone Ana was moving away from Fiji, Tropical Cyclone Bina developed northwest of that nation. A low pressure system northwest of Fiji strengthened on Sunday and the Fiji Meteorological Service designated the system as Tropical Cyclone Bina. More thunderstorms formed near the center of Bina. Those storms generated upper level divergence which pumped mass away from the tropical cyclone. The circulation around Tropical Cyclone Bina was small. Winds to tropical storm force only extended out 80 miles (130 km) from the center of Bina.

Tropical Cyclone Bina will move through an environment marginally favorable for intensification during the next 24 hours. Bina will move over water where the Sea Surface Temperature is near 28°C. An upper level trough east of Australia will produce northwesterly winds which blow toward the top of the tropical cyclone. Those winds will cause moderate vertical wind shear and they will inhibit intensification. Tropical Cyclone Bina will likely maintain its intensity during the next 24 hours.

The upper level trough will steer Tropical Cyclone Bina toward the southeast during the next 36 hours. On its anticipated track Bina could reach Vanua Levu within 18 hours. Tropical Cyclone Bina will bring gusty winds and locally heavy rain to Fiji during the next 36 hours. The stormy conditions will make efforts on Viti Levu and Vanua Levu to recover from Tropical Cyclone Ana more difficult. Heavy rain could make floods caused by Ana to become worse.

Elsewhere over the Southwest Pacific Ocean, Tropical Cyclone Ana was moving away from Fiji and Tropical Cyclone Lucas was strengthening over the Coral Sea. At 10:00 p.m. EST on Sunday the center of Tropical Cyclone Ana was located at latitude 19.9°S and longitude 179.7°E which put it about 105 miles (17 km) south of Suva, Fiji. Ana was moving toward the south-southeast at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 978 mb.

At 10:00 p.m. EST on Sunday the center of Tropical Cyclone Lucas was located at latitude 13.2°S and longitude 156.0°E which put it about 870 miles (1405 km) west-northwest of New Caledonia. Lucas was moving toward the east at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 979 mb. Tropical Cyclone Lucas is forecast to strengthen into the equivalent of a hurricane/typhoon. It could affect New Caledonia and Vanuatu in a few days.

Tropical Cyclone Yasa Strengthens between Fiji and Vanuatu

Tropical Cyclone Yasa strengthened between Fiji and Vanuatu on Sunday. At 4:00 p.m. EST on Sunday the center of Tropical Cyclone Yasa was located at latitude 15.7°S and longitude 172.1°E which put it about 380 miles (610 km) west-northwest of Nadi, Fiji. Yasa was moving toward the west-southwest at 4 m.p.h. (6 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 982 mb.

Tropical Cyclone Yasa strengthened on Sunday after the circulation of former Tropical Cyclone 04P was absorbed by the larger circulation around Yasa. The inner end of a rainband wrapped around the eastern side of the center of circulation. Other bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Yasa. Storms near the center generated upper level divergence which pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 120 miles (195 km) from the center of circulation.

Tropical Cyclone Yasa will be in an environment favorable for intensification during the next several days. Yasa will be over water where the Sea Surface Temperature is near 29°C. It will be in a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Cyclone Yasa will likely intensify into the equivalent of a hurricane/typhoon during the next 18 hours. It could strengthen to the equivalent of a major hurricane in about three days.

Tropical Cyclone Yasa will be in an area where the steering winds are weak during the next 24 hours. Yasa is forecast to make a slow clockwise loop during the next 24 to 36 hours. Eventually, a high pressure system over the South Pacific Ocean will start to steer Tropical Cyclone Yasa toward the southeast. On its anticipated track Tropical Cyclone Yasa could approach Fiji in about four days.

Elsewhere over the South Pacific Ocean, Tropical Cyclone 06P developed north of Tonga. At 4:00 p.m. EST on Sunday the center of Tropical Cyclone 06P was located at latitude 17.8°S and longitude 173.9°W which put it about 60 miles (95 km) north of Neiafu, Tonga. It was moving toward the south-southwest at 9 m.p.h. (15 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 997 mb.
