Tropical Cyclone Gamane Brings Wind and Rain to Northern Madagascar

Tropical Cyclone Gamane brought strong winds and heavy rain to northern Madagacar on Wednesday. At 11:00 a.m. EDT on Wednesday the center of Tropical Cyclone Gamane was located at latitude 13.5°S and longitude 49.1°E which put it about 25 miles (40 km) south of the Ambilobe, Madagascar. Gamane was moving toward the southwest at 6 m.p.h. (10 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 991 mb.

Tropical Cyclone Gamane rapidly intensified to the equivalent of a hurricane/typhoon before it made landfall on the coast of northern Madagascar near Iharana on Tuesday night. The circulation around Gamane was small at the time of landfall. Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Tropical Cyclone Gamane at the time of landfall. Winds to tropical storm force only extended out 65 miles (105 km) from the center of Gamane’s circulation.

Tropical Cyclone Gamane weakened after the center of circulation moved over land. However, the circulation around Tropical Cyclone Gamane remained well organized. Thunderstorms were still occurring near the center of Gamane’s circulation. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center of Gamane generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 65 miles (105 km) from the center of Tropical Cyclone Gamane.

Tropical Cyclone Gamane will move around the western end of a high pressure system over the South Indian Ocean. The high pressure system will steer Gamane toward the south during the next 24 hours. On its anticipated track, Tropical Cyclone Gamane will move toward the south over northern Madagascar. Gamane will continue to weaken while the center of circulation is over land. Even though Tropical Cyclone Gamane will weaken, it will continue to drop heavy rain over parts of northern Madagascar. Heavy rain will cause floods in some locations.

An upper level trough southwest of Madagascar will start to steer Tropical Cyclone Gamane toward the southeast in a day or so. The center of Gamane is likely to move back over the Southwest Indian Ocean on Friday. Tropical Cyclone Gamane could strengthen once the center of circulation moves back over water. Gamane could affect La Reunion and Mauritius during the weekend.

Tropical Cyclone Gamane Forms Near Northern Madagascar

Tropical Cyclone Gamane formed over the South Indian Ocean near northern Madagascar on Monday night. At 8:00 a.m. EDT on Tuesday the center of Tropical Cyclone Gamane was located at latitude 12.2°S and longitude 50.7°E which put it about 90 miles (145 km) east of the Antsiranana, Madagascar. Gamane was moving toward the northwest at 4 m.p.h. (6 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 Indian Ocean near northern Madagascar strengthened during Monday night and Meteo France La Reunion designated the system as Tropical Cyclone Gamane. The circulation around Tropical Cyclone Gamane was organizing quickly. Numerous thunderstorms formed near the center of Gamane’s circulation. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 85 miles (135 km) from the center of Tropical Cyclone Gamane.

Tropical Cyclone Gamane will move through an environment favorable for intensification during the next 24 hours. Gamane will move over water where the Sea Surface Temperatures are near 29°C. It will move under the axis of an upper level ridge over the Southwest Indian Ocean. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. Part of the circulation around the western side of Gamane will move over northern Madagascar, which is the only factor that could inhibit intensification. Tropical Cyclone Gamane will intensify during the next 24 hours. Gamane could intensify rapidly at times. Tropical Cyclone Gamane is likely to strengthen to the equivalent of a hurricane/typhoon, if the center of circulation remains over water.

Tropical Cyclone Gamane will move around the western side of a high pressure system over the South Indian Ocean. The high pressure system will steer Gamane slowly toward the south-southwest during the next 24 hours. On its anticipated track, the center of Tropical Cyclone Gamane will move close to the coast of northeastern Madagascar. The center of circulation could pass very close to Iharana, Sambava, Antalaha, and Ambohitralanana.

Tropical Cyclone Gamane will bring strong winds to the coast of northeastern Madagascar. Gamane will also drop heavy rain over parts of northeastern Madagascar. Tropical Cyclone Gamane will move slowly during the next 24 hours. So, prolonged heavy rain is likely to cause floods in some locations.

Tropical Cyclone Billy Passes South of Cocos Island

Tropical Cyclone Billy passed south of Cocos Island on Tuesday. At 5:00 p.m. EDT on Tuesday the center of Tropical Cyclone Billy was located at latitude 17.8°S and longitude 94.8°E which put it about 385 miles (625 km) south-southwest of Cocos Island. Billy was moving toward the west-southwest at 12 m.p.h (19 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 986 mb.

Tropical Cyclone Billy maintained its intensity over the South Indian Ocean on Tuesday as it passed south of Cocos Island. The inner end of a rainband wrapped around the center of circulation and an elliptical eye was evident on microwave satellite images. A band of strong thunderstorms surrounded the eye and the strongest winds were occurring in the southern part of the ring. A band of strong thunderstorms was south of the center of Billy. Bands in the other parts of the tropical cyclone consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 115 miles (185 km) in the southern half of Tropical Cyclone Billy. Winds to tropical storm force extended out 40 miles (65 km) in the northern half of the circulation.

Tropical Cyclone Billy will move through an environment unfavorable for intensification during the next several days. Billy will move over water where the Sea Surface Temperatures are near 26˚C. It will move north of an upper level trough over the South Indian Ocean. The trough will produce westerly winds that will blow toward the top of Billy’s circulation. Those winds will cause moderate vertical wind shear. There will be drier air north and west of Tropical Cyclone Billy. The drier air will also inhibit intensification. A combination of moderate vertical wind shear and drier air will cause Tropical Cyclone Billy to weaken gradually during the next several days.

Tropical Cyclone Billy will move around the northern part of a high pressure system centered west of Australia. The high pressure system will steer Billy toward the west-southwest during the next several days. On its anticipated track Tropical Cyclone Billy will move farther away from Cocos Island.

Tropical Storm Billy Strengthens South-southeast of Cocos Island

Tropical Cyclone Billy strengthened south-southeast of Cocos Island on Monday. At 5:00 p.m. EDT on Monday the center of Tropical Cyclone Billy was located at latitude 16.8°S and longitude 98.4°E which put it about 330 miles (530 km) south-southeast of Cocos Island. Billy was moving toward the southwest 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.

A low pressure system over the South Indian Ocean south-southeast of Cocos Island strengthened on Monday and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Billy. An eye was apparent on microwave satellite imagery at the center of Tropical Cyclone Billy earlier on Monday, but the eye was gone by later in the afternoon. A partial ring of thunderstorms surrounded the center of Billy’s circulation and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Billy. Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 110 miles (175 km) from the center of Billy.

Tropical Cyclone Billy will move through an environment marginally favorable for intensification during the next 24 hours. Billy will move over water where the Sea Surface Temperatures are near 27˚C. It will move through a region where the upper level winds are weak and there will not be a lot of vertical wind shear. However, there appears to be drier air north and west of Tropical Cyclone Billy. The drier air seems to have been pulled into the core of Billy’s circulation and it may have contributed to the disappearance of the eye on Monday. The drier air will inhibit intensification. Tropical Cyclone Billy could strengthen if more thunderstorms develop around the center of circulation, but the drier air may prevent that from happening.

Tropical Cyclone Billy will move around the northern part of a high pressure system centered west of Australia. The high pressure system will steer Billy toward the west-southwest during the next several days. On its anticipated track Tropical Cyclone Billy will pass south of Cocos Island in 24 hours.

Former Tropical Cyclone Esther Drops Heavy Rain Over Northwestern Australia

Former Tropical Cyclone Esther dropped heavy rain over parts of northwestern Australia on Wednesday.  At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Esther was located at latitude 15.3°S and longitude 130.8°E which put it about 240 miles (390 km) south of Darwin, Australia.  Esther was moving toward the west at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 996 mb.

The circulation around former Tropical Cyclone Esther remained very well organized on Wednesday even though it had been moving across northern Australia for several days.  There was a distinct low level center of circulation.  The circulation was surrounded by bands of showers and thunderstorms.  Strong thunderstorms developed south of Darwin in a band in the northern part of the circulation.  The Darwin harbor reported a wind gust of 44 m.p.h. (72 km/h).  The Wyndham airport reported a wind gust of 39 m.p.h. (63 km/h).

Former Tropical Cyclone Esther could strengthen back into a tropical cyclone if the center of circulation moves over the South Indian Ocean west of Australia.  Esther will move through an environment favorable for intensification during the next day or two.  The Sea Surface Temperature near the west coast of Australia is near 30°C.  Esther will move under an upper level ridge where the winds are weak and there is little vertical wind shear.  Former Tropical Cyclone Esther could intensify rapidly if the center of circulation moves completely over water.

Former Tropical Cyclone Esther will move around the western end of a high pressure system over Australia during the next several days.  The high will steer Esther toward the west during the next 24 to 48 hours.  It will turn more toward the south when it reaches the western end of the high pressure system.  On its anticipated track the center of former Tropical Cyclone Esther will pass near the southern end of the Joseph Bonaparte Gulf.

Elsewhere over the South Indian Ocean, Tropical Cyclone Ferdinand churned northwest of Australia.  At 10:00 p.m. EST the center of Tropical Cyclone Ferdinand was located at latitude 16.6°S and longitude 114.3°E which put it about 400 miles (645 km) north of Learmonth, Australia.  Ferdinand was moving toward the west at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h).  The minimum surface pressure was 966 mb.

Tropical Cyclone Ferdinand Strengthens to Equivalent of Hurricane/Typhoon

Tropical Cyclone Ferdinand strengthened to the equivalent of a hurricane/typhoon over the South Indian Ocean northwest of Australia on Monday night.  At 10:00 p.m. EST on Monday the center of Tropical Cyclone Ferdinand was located at latitude 15.4°S and longitude 117.0°E which put it about 520 miles (840 km) north-northeast of Learmonth, Australia.  Ferdinand was moving toward the southwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 975 mb.

The circulation around Tropical Cyclone Ferdinand exhibited much greater organization on Monday.  A very small circular eye formed at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Storms around the eye generated upper level divergence which was pumping mass away form the tropical cyclone.  Bands of showers and thunderstorms were revolving around the core of Ferdinand.  Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of circulation.  Winds to tropical storm force extended out 70 miles (100 km) from the center.

Tropical Cyclone Ferdinand will move through an environment favorable for intensification during the next 24 to 36 hours.  Ferdinand will move over water where the Sea Surface Temperature is near 29°C.  It will move under an upper level ridge over the South Indian Ocean northwest of Australia.  The upper level winds will be weak and there will be little vertical wind shear.  Tropical Cyclone Ferdinand will continue intensify and it could strengthen to the equivalent of a major hurricane during the next 24 to 36 hours.

Tropical Cyclone Ferdinand will move north of a high pressure system over the South Indian Ocean.  The high will steer Ferdinand slowly toward the west-southwest during the next several days.  On its anticipated track Tropical Cyclone Ferdinand will remain well to the northwest of Western Australia.

Elsewhere, Tropical Cyclone Esther was moving westward over the Northern Territory of Australia.  At 10:00 p.m. EST on Monday the center of Tropical Cyclone Esther was located at latitude 17.3°S and longitude 135.4°E which put it about 125 miles (200 km) east of Newcastle Waters, Australia.  Esther was moving toward the west at 7 m.p.h. (11km/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 997 mb.  Tropical Cyclone Esther was dropping locally heavy rain over parts of the Northern Territory.  A Flood Watch was in effect for the Coastal Carpentaria Rivers, Barkly and the Western Top End.

Tropical Cyclone Esther Makes Landfall in Northern Australia

Tropical Cyclone Esther made landfall in northern Australia just to the east of the border between Queensland and the Northern Territory on Sunday night.  At 10:00 p.m. EST on Sunday the center of Tropical Cyclone Esther was located at latitude 16.7°S and longitude 137.9°E which put it about 65 miles (105 km) west of Mornington Island.  Esther was moving toward the west-southwest at 10 m.p.h. (16 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 988 mb.

A Warning remained in effect for the portion of the coast from Port McArthur to Karumba, Australia including Borroloola and Mornington Island.

Tropical Cyclone Esther was intensifying slowly when it made landfall just east of the border between Queensland and the Northern Territory of Australia.  Winds to tropical storm force extended out 75 miles (120 km) from the center of circulation.  A weather station at Mornington Island reported a sustained wind speed of 35 m.p.h. (57 km/h) and a wind gust of 54 m.p.h. (87 km/h).  The station measured 6.77 inches (172 mm) of rain.

Tropical Cyclone Esther will weaken as it moves inland.  Esther will move north of a high pressure system over Australia.  The high will steer Tropical Cyclone Esther toward the west during the next few days.  On its anticipated track Esther will move across the Northern Territory.  Tropical Cyclone Esther will drop locally heavy rain and it could cause flash floods in some locations.  There is a potential for Esther to strengthen again in a few days when it moves over the South Indian Ocean northwest of Australia.

Elsewhere, Tropical Cyclone Ferdinand developed over the South Indian Ocean northwest of Australia.  At 4:00 p.m. EST on Sunday the center of Tropical Storm Ferdinand was located at latitude 13.8°S and longitude 117.8°E which put it about 450 miles (750 km) north of Port Hedland, Australia.  Ferdinand was moving toward the southwest at 7 m.p.h. (11 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 993 mb.  Tropical Cyclone Ferdinand is forecast to move toward the west-southwest and to strengthen into the equivalent of a hurricane/typhoon.

Tropical Cyclone Trevor Makes Landfall in the Northern Territory

Tropical Cyclone Trevor made landfall on the coast of the Northern Territory of Australia southeast of Port McArthur early on Saturday.  At 11:00 p.m. EDT on Friday the center of Tropical Cyclone Trevor was located at latitude 16.5°S and longitude 137.0°E which put it about 50 miles (80 km) east-southeast of Port McArthur, Northern Territory.  Trevor was moving toward the southwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (230 km/h).  The minimum surface pressure was 949 mb.  A Tropical Cyclone Warning was in effect from Port Roper, Northern Territory to Burketown, Queensland.

Tropical Cyclone Trevor intensified into the equivalent of a major hurricane before it made landfall.  The Hurricane Intensity Index (HII) for Trevor was 17.8.  The Hurricane Size Index (HSI) was 16.8 and the Hurricane Wind Intensity Size Index (HWISI) was 34.6.  Tropical Cyclone Trevor was capable of causing major damage when it made landfall.  It could have generated a storm surge of up to 12 feet (4 meters at the coast).

Tropical Cyclone Trevor will continue to move southwestward and it will gradually weaken as it moves farther inland.  Trevor will also drop heavy rainfall while it moves inland.  Flood Watches have been issued for parts of the eastern Northern Territory and western Queensland.

Elsewhere, Tropical Cyclone Veronica was advancing slowly toward the coast of Western Australia.  At 11:00 p.m. EDT on Friday the center of Tropical Cyclone Veronica was located at latitude 18.9°S and longitude 117.1°E.  Veronica was moving toward the south at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h).  The minimum surface pressure was 962 mb.  A Tropical Cyclone Warning was in effect for the portion of the coast from Wallal to Mardie including Port Hedland and Karratha.

The structure of Tropical Cyclone Veronica changed significantly on Friday.  A large eye with a diameter of about 40 miles (65 km) developed at the center of circulation.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Veronica.  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 150 miles (240 km) from the center.

Tropical Cyclone Veronica is moving around the western end of a subtropical high pressure system.  The high will steer Veronica toward the southeast during the next 24 hours.  On its anticipated track Tropical Cyclone Veronica will make landfall on the coast of Western Australia west of Port Hedland in about 24 hours.  Veronica will be the equivalent of a hurricane/typhoon when it makes landfall and it will be capable of causing serious damage.

Tropical Cyclones Trevor and Veronica Bracket Australia

Tropical Cyclones Trevor and Veronica bracketed Australia on Thursday night.  Tropical Cyclone Veronica was stronger but Tropical Cyclone Trevor was the more immediate threat.  At 11:00 p.m. EDT on Thursday the center of Tropical Cyclone Trevor was located at latitude 14.6°S and longitude 139.4°E which put it about 200 miles (320 km) east-northeast of Port McArthur, Australia.  Trevor was moving toward the southwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (170 km/h).  The minimum surface pressure was 967 mb.  A Tropical Cyclone Warning was in effect for the portion of the coast from Cape Shield, Northern Territory to Karumba, Queensland.

Tropical Cyclone Trevor strengthened more quickly as more of the circulation moved over the Gulf of Carpentaria.  A circular eye formed at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Storms near the core of Trevor generated upper level divergence which pumped mass away from the tropical cyclone.  Bands of showers and thunderstorms were revolving around the core.  Winds to hurricane/typhoon force extended out about 30 miles (50 km) from the center of circulation.  Winds to tropical storm force extended out about 130 miles (210 km) from the center.

Tropical Cyclone Trevor will move through an environment favorable for intensification for about another 24 hours.  Trevor will move over water where the Sea Surface Temperature is near 31°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Trevor will continue to intensify on Friday and it could strengthen into the equivalent of a major hurricane.

Tropical Cyclone Trevor will move around the northwestern side of a subtropical ridge.  The ridge will steer Trevor toward the southwest.  On its anticipated track Tropical Cyclone Trevor will make landfall near Port McArthur in about 24 hours.  Trevor could be a major hurricane at that time.  It will bring strong winds, which could cause a significant storm surge at the coast.  Tropical Cyclone Trevor will drop heavy rain when it moves inland and it could cause flooding in some locations.

At 11:00 p.m. EDT on Thursday the center of Tropical Cyclone Veronica was located at latitude 17.8°S and longitude 116.7°E which put it about 200 miles (355 km) north-northwest of Port Hedland, Australia.  Veronica was moving toward the southwest at 4 m.p.h. (6 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 941 mb.  A Tropical Cyclone Warning was in effect for the portion of the coast from Pardoo to Mardie including Port Hedland and Karratha.

Tropical Cyclone Veronica remains the equivalent of a major hurricane.  A circular eye was surrounded by a ring of strong storms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Veronica.  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 Storm Veronica will remain in an area favorable for intensification for another 24 to 36 hours.  Veronica will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there is little vertical wind shear.  Tropical Cyclone Veronica could strengthen on Friday.

Tropical Cyclone will move around the western end of a ridge of high pressure.  Veronica will move toward the south-southeast after it rounds the end of the ridge.  On its anticipated track Tropical Cyclone Veronica could make landfall on the coast of Western Australia between Karratha and Port Hedland in about 48 hours.  Veronica is likely to be the equivalent of a major hurricane at that time.

Tropical Cyclones Veronica and Trevor Threaten Australia

Tropical Cyclones Veronica and Trevor posed threats to Australia on Wednesday night.  Tropical Cyclone Veronica intensified very rapidly into the equivalent of a major hurricane on Wednesday off the coast of Western Australia.  At 11:00 p.m. EDT on Wednesday the center of Tropical Cyclone Veronica was located at latitude 16.5°S and longitude 117.6°E which put it about 275 miles (445 km) north-northwest of Port Hedland, Australia.  Veronica was moving toward the south-southwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 145 m.p.h. (230 km/h) and there were wind gusts to 175 m.p.h. (280 km/h).  The minimum surface pressure was 929 mb.  A Tropical Cyclone Watch was in effect for the portion of the coast from Pardoo to Mardie including Port Hedland and Karratha.

Tropical Cyclone Veronica intensified very rapidly during the past 24 hours.  Veronica strengthened from the equivalent of a tropical storm to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale.  A small pinhole eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of the circulation.  Storms near the core were generating strong upper level divergence which was pumping mass away from the tropical cyclone.

Tropical Cyclone Veronica had a large circulation.  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 200 miles (320 km) from the center.  The Hurricane Intensity Index (HII) for Tropical Cyclone Veronica was 29.8.  The Hurricane Size Index (HSI) was 18.6 and the Hurricane Wind Intensity Size Index (HWISI) was 48.4.

Tropical Cyclone Veronica will remain in an environment favorable for strong tropical cyclones for several more days.  Veronica will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Veronica could strengthen into the equivalent of a Category 5 hurricane during the next 24 hours.  If a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could cause fluctuations in the intensity of Veronica.

Tropical Cyclone Veronica will move around the western end of a subtropical ridge.  The ridge will steer Veronica toward the south-southwest.  Tropical Cyclone Veronica could move toward the south-southeast after it rounds the western end of the ridge.  On its anticipated track Tropical Cyclone Veronica could approach the coast of Western Australia in about three days.  Veronica could be the equivalent of a major hurricane at that time.

Tropical Cyclone Trevor moved over the eastern Gulf of Carpentaria on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Tropical Cyclone Trevor was located at latitude 13.1°S and longitude 141.1°E which put it about 55 miles (90 km) southwest of Weipa, Australia.  Trevor was moving toward the southwest at 2 m.p.h. (3 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 minium surface pressure was 988 mb.  A Tropical Cyclone Watch was in effect for the coast from Nhulunbuy to Karumba.

The circulation of Tropical Cyclone Trevor was gradually reorganizing as the center moved farther into the Gulf of Carpentaria.  Trevor will move over water where the Sea Surface Temperature is near 31°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Trevor will intensify during the next 48 hours and it could strengthen into the equivalent of a major hurricane.  On its anticipated track Trevor is forecast to approach the southwest of the Gulf of Carpentaria near Port McArthur in about 48 hours.
