Powerful Tropical Cyclone Ilsa Nears Western Australia

Powerful Tropical Cyclone Ilsa neared the coast of Western Australia on Thursday morning. At 5:00 a.m. EDT on Thursday the center of Tropical Cyclone Ilsa was located at latitude 19.1°S and longitude 119.1°E which put it about 75 miles (120 km) northwest of Pardoo Roadhouse, Australia. Ilsa was moving toward the south-southeast at 11 m.p.h. (17 km/h). The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h). The minimum surface pressure was 926 mb.

A Tropical Cyclone Warning was in effect for the coast of Western Australia from Bidyadanga to Whim Creek. The Warning included Port Hedland. The Tropical Cyclone Warning extended inland to include De Grey, Marble Bar, Nullagine, Telfer and Parnngurr.

Tropical Cyclone Ilsa continued to intensify during Wednesday night, as it moved closer to the coast of Western Australia. A very small circular eye was present at the center of Ilsa’s circulation. The 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 Tropical Cyclone Ilsa. Storms near the core generated strong upper level divergence that pumped large quantities of mass away from the tropical cyclone. The removal of large quantities of mass was causing the surface pressure to continue to decrease.

A weather station at Bedout Island measured a sustained wind speed of 120 m.p.h. (104 kt or 193 km/h) as the core of Tropical Cyclone Ilsa was approaching it. The weather station also measured a wind gust of 144 m.p.h. (125 kt or 232 km/h).

The size of the circulation around Tropical Cyclone Ilsa increased as it intensified. Winds to hurricane/typhoon force extended out 50 miles (80 km) from the center of Tropical Cyclone Ilsa. Winds to tropical storm force extended out 140 miles (225 km) from the center. The Hurricane Intensity Index (HII) for Tropical Cyclone Ilsa was 31.6. The Hurricane Size Index (HSI) was 18.4 and the Hurricane Wind Intensity Size Index (HWISI) was 50.0. Tropical Cyclone Ilsa was similar in size and intensity to Hurricane Laura when Laura hit southwest Louisiana in 2020.

Tropical Cyclone Ilsa will move through an environment favorable for a powerful tropical cyclone during the next few hours. Ilsa will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the axis of an upper level ridge that extends from northern Australia to 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 Ilsa is likely to maintain its intensity until it reaches the coast of Western Australia.

Tropical Cyclone Ilsa will move around the western end of a high pressure system over western Australia. The high pressure system will steer Ilsa toward the southeast during the next 24 hours. On its anticipated track, the center of Tropical Cyclone Ilsa is likely to make landfall on the coast of Western Australia near Pardoo Roadhouse in 6 hours. Ilsa will be the equivalent of a major hurricane when it makes landfall.

Tropical Cyclone Ilsa will bring very strong winds and locally heavy rain to Western Australia between De Grey and Wallal Downs. The strong winds will be capable of causing regional severe damage. Ilsa could also produce strong winds in De Grey and Telfer when it moves inland. Heavy rain could cause flash floods in some locations. Flood Warnings are in effect for the De Grey River and the Sandy Sesert. Flood Watches are in effect for the West Kimberley, Western Desert, Warburton and Salt Lake Districts. Tropical Cyclone Ilsa could also cause a storm surge of up to 10 to 15 feet (3 to 4.5 meters) along the portion of the coast near where the center makes landfall.

(11 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 979 mb.

A Warning was in effect for the portion of the coast of Western Australia from Wallal Downs to Mardie including Port Hedland, Karratha and Dampier.  A Watch was in effect for the coast from Mardia to Onslow.

Tropical Cyclone Damien organized quickly on Thursday.  Microwave satellite imagery suggested that a small eye could be forming at the center of Damien.  A small ring of thunderstorms surrounded the forming eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Damien.  Storms near the core were generating upper level divergence which was pumping mass away from the tropical cyclone.  Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation.

Tropical Cyclone Damien will move through an environment favorable for intensification during the next 24 hours.  Damien will move over water where the Sea Surface Temperature is near 30°C.  It will move under the western end of an upper level ridge over Australia.  The ridge will produce northeasterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification.  Tropical Cyclone Damien will strengthen during the next 24 hours and it could rapidly intensify into the equivalent of a major hurricane.

Tropical Cyclone Damien will move around the western end of a high pressure system centered over Australia.  The high will steer Damien toward the south during the next 24 hours.  On its anticipated track the center of Tropical Cyclone Damien could make landfall on the coast of Western Australia in the vicinity of Dampier, Karratha and Wickham in about 24 hours.  Damien could be the equivalent of a major hurricane when it reaches the coast.  It will produce strong gusty winds.  Tropical Cyclone Damien will also drop locally heavy rain and flash floods could occur in some locations.

Elsewhere over the South Indian Ocean, Tropical Cyclone Francisco weakened east of Rodrigues.  At 4:00 a.m. EST on Thursday the center of Tropical Cyclone Francisco was located at latitude 19.3°S and longitude 71.7°E which put it about 565 miles (910 km) east of Port Mathurin, Mauritius.  Francisco was moving toward the southeast at 13 m.p.h. (20 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 1001 mb

Tropical Cyclone Develops Near Western Australia, Watch Issued

A tropical cyclone currently designated as 14S (SH14) developed near the coast of Western Australia on Wednesday and a Watch was issued for a portion of the coast.  At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone 14S was located at latitude 17.1°S and longitude 120.2°E which put it about 250 miles (400 km) north-northeast of Port Hedland, Australia.  The tropical cyclone was moving toward the west-southwest at 10 m.p.h. (16 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 998 mb.  A Watch was issued for a portion of the coast of Western Australia from Wallal Downs to Onslow including Port Hedland, Karratha and Dampier.

A Tropical Low previously located over Western Australia moved westward over the South Indian Ocean on Wednesday and it strengthened into Tropical Cyclone 14S.  The circulation around the tropical cyclone was still organizing on Wednesday night.  More thunderstorms were forming near the center of circulation.  Bands of showers and thunderstorms were developing and the bands were revolving around the center of the tropical cyclone.  Storms near the center began to generate upper level divergence which was pumping mass away from the tropical cyclone.

Tropical Cyclone 14S will move through an environment favorable for intensification during the next 48 hours.  The tropical cyclone will move over water where the Sea Surface Temperature is near 30°C.  It will move under the northwestern part of an upper level ridge centered over northern Australia.  The ridge will produce easterly winds which will blow toward the top of the circulation.  Those winds will cause moderate vertical wind shear, but the shear will not be strong enough to prevent intensification.  Tropical Cyclone 14S will continue to intensify and it could strengthen into the equivalent of a hurricane/typhoon in 24 to 36 hours.

Tropical Cyclone 14S will move around the northwestern end of a high pressure system over Australia.  The high will steer the tropical cyclone toward the west-southwest during the next 12 to 24 hours.  Tropical Cyclone 14S will turn more toward the south on Friday when it reaches the western end of the high pressure system.  On its anticipated track Tropical Cyclone 14S could approach the coast of Western Australia between Port Hedland and Karratha in about 48 hours.  It will likely be the equivalent of a hurricane/typhoon when it approaches the coast.

Elsewhere over the South Indian Ocean, Tropical Cyclone Francisco formed northeast of Rodrigues.  At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Francisco was located at latitude 17.8°S and longitude 70.4°E which put it about 485 miles (785 km) east-northeast of Port Mathurin, Mauritius.  Francisco was moving toward the east-southeast at 13 m.p.h. (20 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.

(10 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 55 m.p.h. (90 km/h).  The minimum surface pressure was 990 mb.

The center of Tropical Cyclone Blake moved across the coast of Western Australia just to the west of Wallal Downs on Tuesday.  Blake was beginning to weaken, but winds to tropical storm force were still occurring in the northwestern part of the circulation that was still over water.  A weather station at Bedout Island which is just off the coast of Western Australia was reporting a sustained wind speed of 43 m.p.h. (69 km/h) and wind gusts to 50 m.p.h. (82 km/h).  A weather station in Mandora, Australia had already received 2.69 inches (64.4 mm) of rain from the rainbands in eastern side of the tropical cyclone.

Tropical Cyclone Blake will move around the western end of a high pressure system over Australia.  Blake will move more toward the south when it reaches the western end of the high.  On its anticipated track the center of Tropical Cyclone Blake could be near Marble Bar in about 12 hours.  Blake could approach Newman in about 24 hours.  Tropical Cyclone Blake will weaken as it moves farther inland.  Blake could drop locally heavy rain over parts of Western Australia and the potential for flash floods exists.
