Tropical Cyclone Ilsa Strengthens to Equivalent of Cat. 4 Hurricane

Tropical Cyclone Ilsa strengthened to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Tropical Cyclone Ilsa was located at latitude 18.1°S and longitude 119.2°E which put it about 175 miles (285 km) northwest of Wallal Downs, Australia. Ilsa was moving toward the south-southwest at 7 m.p.h. (11 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 942 mb.

A Tropical Cyclone Warning was in effect for the coast of Western Australia from south of Broome 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 strengthened to the equivalent of a Category 4 hurricane on Wednesday night. A 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 Rowley Shoals measured a sustained wind speed of 95 m.p.h. (83 kt or 154 km/h). The weather station measured a wind gust of 132 m.p.h. (115 kt or 213 km/h). It also measured a sea level pressure of 942.3 mb.

Winds to hurricane/typhoon force extended out 35 miles (55 km) from the center of Tropical Cyclone Ilsa. Winds to tropical storm force extended out 120 miles (195 km) from the center. The Hurricane Intensity Index (HII) for Tropical Cyclone Ilsa was 25.1. The Hurricane Size Index (HSI) was 13.4 and the Hurricane Wind Intensity Size Index (HWISI) was 38.5. Tropical Cyclone Ilsa was similar in size and intensity to Hurricane Harvey hit Texas in 2017.

Tropical Cyclone Ilsa will move through an environment favorable for intensification during the next 12 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 could continue to intensify during the next 12 hours.

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 between Pardoo Roadhouse and Wallal Downs in 12 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 Pardoo Roadhouse 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 Watches are in effect for the West Kimberley, De Grey River, Sandy Desert, 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.

The circulation around former Tropical Cyclone Ellie was still very well organized. The strongest winds were occurring in bands of thunderstorms over water and near the coast of Western Australia. Thunderstorms were occurring in bands in the southern and western sides of Ellie’s circulation. Bands in the northern and eastern sides of the circulation consisted primarily of showers and lower clouds. Storms near the center of Ellie generated upper level divergence that pumped mass away from the former tropical cyclone. The removal of mass allowed the surface pressure to remain near 990 mb even though the center of circulation was over land.

Former Tropical Cyclone Ellie is likely to remain nearly stationary near Broome during the next 24 hours. The bands of thunderstorms are likely to continue to drop locally heavy rain over parts of Western Australia. A Major Flood Warning remains in effect for the Fitzroy River. A Flood Warning is in effect for the West Kimberley District. A Flood Watch is in effect for the Sandy Desert.

It will move through are region where the upper level winds are weak and there will be little vertical wind shear. Tropical Cyclone Anika will strengthen during the next 24 hours. However a portion of Anika’s circulation will still be over land, which will inhibit intensification.

Tropical Cyclone Anika will continue to bring gusty winds and locally heavy rain to parts of the coast of Western Australia. A Warning is in effect for the portion of the coast from Beagle Bay to Bidyadanga. The Warning includes Broome. A Watch is in effect for the portion of the coast from Bidyadanga to De Grey.

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.
