Tropical Cyclone Errol Makes Landfall in Western Australia

Tropical Cyclone Errol made landfall on the coast of Western Australia on Friday.  At 5:00 a.m. EDT on Friday the center of Tropical Cyclone Errol was located at latitude 16.1°S and longitude 124.3°E which put the center about 20 miles (35 km) south-southwest of Kuri Bay, Australia.  Errol was moving toward the east 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. (105 km/h).  The minimum surface pressure was 998 mb.

Tropical Cyclone Errol made landfall on the coast of Western Australia south-southwest of Kuri Bay on Friday.  Errol was weakening at the time of landfall.  Tropical Cyclone Errol was the equivalent of a tropical storm when it made landfall.  The circulation around Errol was small.  Winds to tropical storm force extended out 70 miles (110 km) from the center of Tropical Cyclone Errol.

An upper level trough near the coast of Western Australia will steer Tropical Cyclone Errol toward the east-southeast during the next 24 hours.  On its anticipated track, Tropical Cyclone Errol will move inland over Western Australia.  The center of Errol’s circulation will move southeast of Kuri Bay.

Tropical Cyclone Errol will bring gusty winds and locally heavy rain to parts of Western Australia south of Kuri Bay.  Heavy rain could cause flash floods in some locations.

Tropical Cyclone Errol Weakens Rapidly

Tropical Cyclone Errol weakened rapidly as it approached the coast of Western Australia on Thursday.  At 5:00 p.m. EDT on Thursday the center of Tropical Cyclone Errol was located at latitude 16.2°S and longitude 122.1°E which put the center about 135 miles (220 km) north-northwest of Broome, Australia.  Errol was moving toward the east-southeast at 14 m.p.h. (22 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 980 mb.

A Warning is in effect for the coast of Western Australia from Kuri Bay to Broome.  The Warning includes Derby.

Tropical Cyclone Errol weakened rapidly as it approached the coast of Western Australia on Thursday.  An upper level trough near the coast of Western Australia was producing strong northwesterly winds that were blowing the top of Errol’s circulation.  Those winds were causing strong vertical wind shear.  The strong vertical wind shear was causing Tropical Cyclone Errol to weaken rapidly.

The strong vertical wind shear was also affecting the structure of Tropical Cyclone Errol.  Thunderstorms were still occurring in bands in the eastern side of Errol’s circulation.  Bands in the western side of Tropical Cyclone Errol consisted primarily of showers and lower clouds.

The circulation around Tropical Cyclone Errol was small.  Winds to hurricane/typhoon force extended out 15 miles (25 km) in the eastern side of Errol’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Tropical Cyclone Errol.

Tropical Cyclone Errol will move through an environment unfavorable for intensification during the next 12 hours. Errol will move over water where where the Sea Surface Temperatures are near 30°C.  However, the upper level trough near the coast of western Australia will continue to produce strong northwesterly winds that will blow toward the of Errol’s circulation.  Those winds will continue to cause strong vertical wind shear.  The strong vertical wind shear will cause Tropical Cyclone Errol to continue to weaken rapidly.

The upper level trough near the coast of Western Australia will steer Tropical Cyclone Errol toward the east-southeast during the next 24 hours.  On its anticipated track, the center of Tropical Cyclone Errol will make landfall near Cape Leveque in about 12 hours.  The center of Errol’s circulation will pass north of Derby.

Tropical Cyclone Errol will bring strong winds and locally heavy rain to the part of Western Australia near Cape Leveque and northeast of Derby.  Heavy rain could cause flash floods in some locations.

Tropical Cyclone Errol Rapidly Intensifies to Equivalent of Cat. 5 Hurricane

Tropical Cyclone Errol rapidly intensified to the equivalent of a Category 5 hurricane over the South Indian Ocean northwest of Australia on Wednesday.  At 11:00 a.m. EDT on Wednesday the center of Tropical Cyclone Errol was located at latitude 14.2°S and longitude 118.9°E which put the center about 325 miles (520 km) northwest of Broome, Australia.  Errol was moving toward the southwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 160 m.p.h. (260 km/h) and there were wind gusts to 195 m.p.h. (315 km/h).   The minimum surface pressure was 919 mb.

A Watch is in effect for the coast of Western Australia from Kuri Bay to Broome.  The Watch includes Derby.

Tropical Cyclone Errol rapidly intensified to the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale on Wednesday.  A very small circular eye with a diameter of 10 miles (16 km) was at the center of Errol’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Errol.  Storms near the core of Errol generated upper level divergence that pumped large quantities of mass away from the tropical cyclone.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The size of the circulation around Tropical Cyclone Errol increased while Errol rapidly intensified.  Winds to hurricane/typhoon force extended out 40 miles (65 km) from the center of Errol’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Tropical Cyclone Errol.

The Hurricane Intensity Index (HII) for Tropical Cyclone Errol is 35.0.  The Hurricane Size index (HSI) is 12.8 and the Hurricane Wind Intensity Size Index (HWISI) is 47.8.  Tropical Cyclone Errol is similar in size and intensity to Hurricane Michael when Michael hit Northwest Florida in 2018.

Tropical Cyclone Errol will move through an environment favorable for a powerful tropical cyclone during the next 24 hours.  Errol will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge over Australia and the South Indian Ocean.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Tropical Cyclone Errol could continue to intensify during the next 24 hours unless an eyewall replacement cycle occurs.  If the inner end of a rainband wraps around the existing eye and eyewall, then concentric eyewalls could cause Errol to weaken.  An upper level trough over the South Indian Ocean will approach Tropical Cyclone Errol on Thursday.  The upper level trough will cause the vertical wind shear to increase.  More vertical wind shear will cause Errol to weaken.

Tropical Cyclone Errol will move around the northwestern part of a high pressure system over Australia.  The high pressure system will steer Errol toward the southwest during the next 24 hours.  On its anticipated track, Tropical Cyclone Errol will remain north of Western Australia during the next day or so.  The upper level trough over the South Indian Ocean will cause Errol to start to move back toward the southeast on Thursday.

Tropical Cyclone Errol Rapidly Intensifies to Equivalent of a Major Hurricane

Tropical Cyclone Errol rapidly intensified to the equivalent of a major hurricane over the South Indian Ocean northwest of Australia during Tuesday night.  At 5:00 a.m. EDT on Wednesday the center of Tropical Cyclone Errol was located at latitude 14.2°S and longitude 119.1°E which put the center about 325 miles (520 km) northwest of Broome, Australia. Errol was moving toward the west-southwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 140 m.p.h. (220 km/h) and there were wind gusts to 165 m.p.h. (265 km/h).  The minimum surface pressure was 940 mb.

Tropical Cyclone Errol rapidly intensified to the equivalent of a  major hurricane during Tuesday night.  A very small circular eye with a diameter of 8 miles (13 km) was at the center of Errol’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Tropical Errol.  Storms near the core of Errol 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 Errol was small.  Winds to hurricane/typhoon force extended out 20 miles (30 km) from the center of Errol’s circulation.  Winds to tropical storm force extended out 75 miles (120 km) from the center of Tropical Cyclone Errol.

The Hurricane Intensity Index (HII) for Tropical Cyclone Errol is 28.3.  The Hurricane Size index (HSI) is 7.2 and the Hurricane Wind Intensity Size Index (HWISI) is 35.5  Tropical Cyclone Errol is similar in size and intensity to Hurricane Charley when Charley hit Southwest Florida in 2004.

Tropical Cyclone Errol will move through an environment favorable for intensification during the next 24 hours.  Errol will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge over Australia and the South Indian Ocean.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Tropical Cyclone Errol could continue to intensify during the next 24 hours unless an eyewall replacement cycle occurs.  If the inner end of a rainband wraps around the existing eye and eyewall, then concentric eyewalls could cause Errol to weaken.

Tropical Cyclone Errol will move around the northwestern part of a high pressure system over Australia.  The high pressure system will steer Errol toward the southwest during the next 24 hours.  On its anticipated track, Tropical Cyclone Errol will remain north of Western Australia during the next day or so.  Errol could start to move back toward the southeast on Thursday.

Tropical Low Causes Warning for Western Australia

The risk posed by a Tropical Low caused the Australia Bureau of Meteorology to issue a Warning for a portion of the coast of Western Australia on Saturday.  At 5:00 p.m. EDT on Saturday the center of the Tropical Low was located at latitude 12.2°S and longitude 125.8°E which put the center about 260 miles (420 km) north-northeast of Kuri Bay, Australia.  The Tropical Low was moving toward the southwest 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 1003 mb.

A Warning is in effect for the portion of the coast of Western Australia from Kalumburu to Kuri Bay.

A Watch is in effect for the portion of the coast of Western Australia from Kuri Bay to Cockatoo Island.

The U.S. Joint Typhoon Warning Center designated the Tropical Low as Tropical Cyclone 29S.

The Tropical Low was strengthening gradually as it moved near the northern coast of Western Australia.  Vertical wind shear was still causing the distribution of thunderstorms to be asymmetrical.  The Tropical Low was under the northern part of an upper level ridge that extended from Australia to the South Indian Ocean.  The upper level ridge was producing northeasterly winds that were causing the vertical wind shear.  Most of the thunderstorms were occurring in bands in the southern half of the Tropical Low.  Bands in the northern side of the Tropical Low consisted primarily of showers and lower clouds.  Storms near the center of circulation generated upper level divergence that pumped mass away to the south and west of the Tropical Low.  The removal of mass in the upper levels was nearly equal to the inflow of mass in the lower levels of the atmosphere.  The balance of inflow and outflow was causing the surface pressure to remain constant.

The asymmetric distribution of thunderstorms was also causing the pattern of wind speeds to be asymmetrical.  Winds to tropical storm force extended out 115 miles (185 km) in the southern side of the Tropical Low.  The winds in the northern part of the Tropical Low were blowing at less than tropical storm force.

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 where the Sea Surface Temperatures are near 30°C.  The northern part of an upper level ridge over Australia and the South Indian Ocean will continue to produce northeasterly winds that will blow toward the top of the Tropical Low.  Those winds will cause some vertical wind shear.  The wind shear will inhibit intensification, but the Tropical Low is likely to intensify gradually during the next 24 hours.

The Tropical Low will move around the northwestern part of a high pressure system over Australia.  The high pressure system will steer the Tropical Low toward the southwest during the next 24 hours.  On its anticipated track, the Tropical Low will move parallel to the coast of Western Australia.

The Tropical Low could bring gusty winds and locally heavy rain to the coast of Western Australia between Kalumburu and Kuri Bay.  Heavy rain could cause flash floods in some locations.

Tropical Low Prompts Watch for Western Australia

The risk posed by a Tropical Low over the Timor Sea caused the Australian Bureau of Meteorology to issue a Watch for a portion of the coast of Western Australia on Friday.  At 11:00 a.m. EDT on Friday the center of the Tropical Low was located at latitude 9.8°S and longitude 129.1°E which put the center about 215 miles (350 km) northwest of Darwin, Australia.  The Tropical Low was moving toward the south-southwest 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 45 m.p.h. (75 km/h).  The minimum surface pressure was 1000 mb.

A Watch was in effect for the portion of the coast of Western Australia from Cockatoo Island to the Berkeley River Mouth.  The Watch included Kalumburu and Kuri Bay.

The U.S. Joint Typhoon Warning Center was designating the Tropical Low as Invest 96P.

Vertical wind shear was causing the distribution of thunderstorms to be asymmetrical.  The Tropical Low as under the northern part of an upper level ridge that extended from Australia to the South Indian Ocean.  The upper level ridge was producing northeasterly winds that were causing the vertical wind shear.  Most of the thunderstorms were occurring in bands in the western half of the Tropical Low.  Bands in the eastern side of the Tropical Low consisted primarily of showers and lower clouds.  Storms near the center of circulation generated upper level divergence that pumped mass away to the west of the Tropical Low.  The removal of mass in the upper levels was nearly equal to the inflow of mass in the lower levels of the atmosphere.  The balance of inflow and outflow was causing the surface pressure to remain constant.

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 where the Sea Surface Temperatures are near 30°C.  The northern part of an upper level ridge over Australia and the South Indian Ocean will continue to produce northeasterly winds that will blow toward the top of the Tropical Low.  Those winds will cause some vertical wind shear.  The wind shear will inhibit intensification, but the Tropical Low is likely to intensify gradually during the next 24 hours.

The Tropical Low will move around the northwestern part of a high pressure system over Australia.  The high pressure system will steer the Tropical Low toward the southwest during the next 24 hours.  On its anticipated track, the low pressure system will move away from Darwin.  The low pressure system could pass near Cape Londonderry and Cape Bougainville on Saturday.

 

Tropical Cyclone Dianne Brings Wind and Rain to Western Australia

Tropical Cyclone Dianne brought wind and rain to Western Australia on Friday.  At 5:00 p.m. EDT on Friday the center of Tropical Cyclone Dianne was located at latitude 16.6°S and longitude 123.8°E which put the center about 75 miles (120 km) north-northeast of the Derby, Australia.  Dianne was moving toward the south at 8 m.p.h. (13 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 991 mb.

A Warning is in effect for the portion of the coast between Kuri Bay and Derby.

The center of Tropical Cyclone Dianne made landfall on the coast of Western Australia north-northeast of Derby.  Dianne was the equivalent of a tropical storm at the time of landfall.  The circulation around Tropical Cyclone Dianne was small.  Winds to tropical storm force only extended out 65 miles (105 km) from the center of Dianne’s circulation.

Tropical Cyclone Dianne will move around the western end of a high pressure system over northern Australia.  The high pressure system will steer Dianne toward the south during the next 24 hours.  On its anticipated track, Tropical Cyclone Dianne will move inland over Western Australia during the next 24 hours.

Tropical Cyclone Dianne will bring strong winds and locally heavy rain to parts of Western Australia.  Heavy rain could cause flash floods in some locations.

Flood Watches are in effect for the Tanami Desert, the Western Desert and the Sandy Desert.

Elsewhere over the South Indian Ocean, Tropical Cyclone Courtney intensified to the equivalent of a major hurricane southwest of the Cocos Islands.  At 5:00 p.m. EDT on Friday the center of Tropical Cyclone Courtney was located at latitude 17.6°S and longitude 92.5°E which put the center about 445 miles (715 km) southwest of the Cocos Islands.  Courtney was moving toward the west-southwest at 18 m.p.h. (30 km/h).  The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 160 m.p.h. (260 km/h).  The minimum surface pressure was 948 mb.

Tropical Cyclone Dianne Nears Western Australia

Tropical Cyclone Dianne neared the coast of Western Australia on Friday morning.  At 5:00 a.m. EDT on Friday the center of Tropical Cyclone Dianne was located at latitude 15.3°S and longitude 123.6°E which put the center about 140 miles (225 km) north of the Derby, Australia.  Dianne was moving toward the south-southeast 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 991 mb.

A Warning is in effect for the area between Kuri Bay and Derby.

A Tropical Low strengthened to Tropical Cyclone Dianne near the coast of Western Australia during Thursday night.  More thunderstorms formed near the center of Tropical Cyclone Dianne.  More thunderstorms also formed in bands revolving around the center of Dianne’s circulation.  Storms near the center of Dianne generated more upper level divergence that pumped mass away from the tropical cyclone.  The removal of more mass caused the surface pressure to decrease.

The circulation around Tropical Cyclone Dianne was small.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Dianne’s circulation.

Tropical Cyclone Dianne will move through an environment somewhat favorable for intensification during the next few hours.  Dianne will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the northern part of an upper level ridge that extends from over Australia to the South Indian Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of the Tropical Low.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification.  Dianne could intensify during the next few hours.

Tropical Cyclone Dianne will move around the western end of a high pressure system over northern Australia.  The high pressure system will steer Dianne toward the southeast during the next 24 hours.  On its anticipated track, Tropical Cyclone Dianne will make landfall on the coast of Western Australia northeast of Derby in a few hours.

Tropical Cyclone Dianne will bring strong winds and locally heavy rain to parts of Western Australia.  Heavy rain could cause flash floods in some locations.

Flood Watches are in effect for the Tanami Desert, the Western Desert and the Sandy Desert.

Elsewhere over the South Indian Ocean, Tropical Cyclone Courtney passed south of the Cocos Islands.  At 5:00 a.m. EDT on Friday the center of Tropical Cyclone Courtney was located at latitude 16.9°S and longitude 94.9°E which put the center about 330 miles (530 km) south-southwest of the Cocos Islands.  Courtney was moving toward the west at 18 m.p.h. (30 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 972 mb.

Tropical Low Prompts Watch for Western Australia

A risk posed by a Tropical Low prompted the Australian Bureau of Meteorology to issue a Watch for a portion of the coast of Western Australia on Thursday.  At 5:00 a.m. EDT on Thursday the center of the Tropical Low was located at latitude 13.8°S and longitude 121.8°E which put the center about 215 miles (350 km) west-northwest of the Kuri Bay, Australia.  The Tropical Low was moving toward the east-northeast at 5 m.p.h. (7 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 997 mb.

A Watch is in effect for the portion of the coast of Western Australia from Mitchell Plateau to Beagle Bay.  The Watch includes Derby and Beagle Bay.

A low pressure system over the South Indian Ocean west of Australia exhibited more organization on Thursday morning and the Australian Bureau of Meteorology classified the system as a Tropical Low.  The U.S. Joint Typhoon Warning Center designated the low pressure system as Invest 93S.

The distribution of thunderstorms in the Tropical Low was asymmetrical.  Thunderstorms were occurring in bands in the western side of the Tropical Low.  Bands in the eastern side of the Tropical Low consisted primarily of showers and lower clouds.  Storms near the center of circulation generated upper level divergence that pumped mass away to the west of the Tropical Low.  The removal of mass caused the surface pressure to decrease slowly.

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 where the Sea Surface Temperatures are near 29°C.  It will move under the northern part of an upper level ridge that extends from over Australia to the South Indian Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of the Tropical Low.  Those winds will cause moderate vertical wind shear.  The moderate vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification.  The Tropical Low could intensify during the next 24 hours.

The Tropical Low will move around the western end of a high pressure system over northern Australia.  The high pressure system will steer the Tropical Low toward the southeast during the next 24 hours.  On its anticipated track, the Tropical Low will make landfall on the coast of Western Australia between Kuri Bay and Derby in 36 hours.

The Tropical Low will bring strong winds and locally heavy rain to parts of Western Australia.  Heavy rain could cause flash floods in some locations.

Elsewhere over the South Indian Ocean, Tropical Cyclone Courtney continued to strengthen south-southeast of the Cocos Islands.  At 5:00 a.m. EDT on Thursday the center of Tropical Cyclone Courtney was located at latitude 16.8°S and longitude 99.5°E which put the center about 380 miles (610 km) south-southeast of the Cocos Islands.  Courtney was moving toward the west at 12 m.p.h. (19 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 973 mb.

Tropical Cyclone Anika Moves along Western Australia Coast

Tropical Cyclone Anika moved along the coast of Western Australia on Sunday afternoon. At 1:00 p.m. EST on Sunday the center of Tropical Cyclone Anika was located at latitude 15.2°S and longitude 125.7°E which put it about 90 miles (145 km) southwest of Kalumburu, Australia. Anika was moving toward the southwest at 8 m.p.h (13 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.

Tropical Cyclone Anika moved along the coast of Western Australia on Sunday afternoon. The center of Anika’s circulation was still over land. The strongest winds were occurring in the northwestern quadrant of Tropical Cyclone Anika, which was still over water. Winds to tropical storm force extended out 70 miles (110 km) in the northwestern quadrant of Anika. The winds over land were blowing at less than tropical storm force.

A Warning was in effect for the portion of the coast from Troughton Island to Beagle Bay. The Warning included Cape Leveque and Derby. A Watch was in effect for the portion of the coast from Beagle Bay to Bidyadanga. The Watch included Broome.

The circulation around Tropical Cyclone Anika remained well organized even though the center was over land. The inner end of a rainband wrapped around the northern side of the center of Anika. The strongest thunderstorms were occurring in a bands in the western side of the circulation. There was also a strong band in the eastern periphery of Tropical Cyclone Anika. Bands in other parts of the circulation consisted primarily of showers and lower clouds. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone.

Tropical Cyclone Anika will move around the northwestern part of a high pressure system over Australia. The high pressure system will steer Anika toward the southwest during the next 24 hours. On its anticipated track Tropical Cyclone Anika will continue to move along the coast of Western Australia. Anika will bring gusty winds and locally heavy rain to places near the coast. Locally heavy rain could cause flash floods in some locations. Flood Warnings are in effect for the North Kimberly District and the West Kimberly District. Flood Watches are in effect for the Sandy Desert and for the Fitzroy River. The center of Anika could move back over water southwest of Kuri Bay on Monday.

Tropical Cyclone Anika is not likely to strengthen while the center is over land. However, since a portion of Anika’s circulation will be over water where the Sea Surface Temperatures are near 30˚C, it could maintain its current intensity. Tropical Cyclone Anika will move through an area where the upper level winds are weak and there will be little vertical wind shear. Anika could strengthen again, if the center of circulation moves back over water.

Elsewhere over the South Indian Ocean, Tropical Cyclone Vernon weakened east-southeast of Diego Garcia. At 1:00 p.m. EST on Sunday the center of Tropical Cyclone Vernon was located at latitude 12.4°S and longitude 88.3°E which put it about 1140 miles (1835 km) east-southeast of Diego Garcia. Vernon was moving toward the east at 13 m.p.h (09 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 978 mb.
