Tropical Cyclone Narelle has passed over the Cape York Peninsula and Narelle is now over the Gulf of Carpentaria.  At 11:00 a.m. EDT on Friday the center of Tropical Cyclone Narelle was located at latitude 13.4°S and longitude 140.3°E which put the center about 260 miles (420 km) east of Alyangula, Australia.  Narelle was moving toward the west 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 972 mb.

The Australian Bureau of Meteorology issued a Warning that is in effect for the portion of the coast of the Northern Territory from Nhulunbuy to Port McArthur.  A Warning also remains in effect for the west coast of the Cape York Peninsula from Mapoon to Cape Keerweer.  That Warning includes Weipa.

The Australian Bureau of Meteorology has issued a Watch for the portion of the coast of the Northern Territory from west of Nhulunbuy to Ramingining.

Tropical Cyclone Narelle weakened as it moved across the central part of the Cape York Peninsula.  However, the circulation around Narelle was still intact.  A well defined center of circulation was visible on satellite images.  Bands of showers and thunderstorms were revolving around the center of Narelle’s circulation.  A little drier air did appear to be pulled into the southwestern part of Tropical Cyclone Narelle.

The size of the circulation around Tropical Cyclone Narelle decreased as Narelle weakened.  Winds to hurricane/typhoon force extended out 20 miles (30 km) from the center of Narelle’s circulation.  Winds to tropical storm force extended out 120 miles (195 km) from the center of Tropical Cyclone Narelle.

Tropical Cyclone Narelle will move through an environment favorable for intensification during the next 24 hours.  Narelle will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge that is over the northern part of Australia.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Cyclone Narelle is likely to intensify again during the next 24 hours.

Tropical Cyclone Narelle will move around the northern side of a high pressure system that is over Australia.  The high pressure system will steer Narelle toward the west during the next 24 hours.  On its anticipated track, Tropical Cyclone Narelle will coast of the Northern Territory in 24 hours.

Tropical Cyclone Narelle will bring strong winds and heavy rain to the Northern Territory heavy rain is likely to cause flash floods in some locations.  Narelle will also cause a storm surge of up to 10 feet (3 meters) along parts of the west coast of the Gulf of Carpentaria.

Flood Watches are in effect for the Top End of Australia.

Tropical Cyclone 24P Forms over the Coral Sea

Tropical Cyclone 24P formed over the Coral Sea on Tuesday night.  At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone 24P was located at latitude 14.3°S and longitude 150.6°E which put the center about 380 miles (615 km) east-northeast of Cairns, Australia.  Tropical Cyclone 24P was moving toward the south-southeast at 3 m.p.h. (5 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 996 mb.

The Australian Bureau of Meteorology issued a Watch for the portion of the coast from Cooktown to Lucinda.  The Watch included Port Douglas, Cairns, Innisfail and Palm Island.

A low pressure system over the Coral Sea strengthened on Tuesday night and the U.S. Joint Typhoon Warning Center designated the system as Tropical Cyclone 24P.  The Australian Bureau of Meteorology was designating the system as Tropical Low 29U.

The distribution of thunderstorms in Tropical Cyclone 24P was asymmetrical.  Thunderstorms were occurring in bands in the western half of the tropical cyclone’s circulation.  Bands in the eastern side of the circulation consisted primarily of showers and lower clouds.  Storms near the center of Tropical Cyclone 24P began to generate upper level divergence that pumped mass away to the west of the tropical cyclone.

Winds to tropical storm force extended out 100 miles (160 km) from the center of Tropical Cyclone 24P.

Tropical Cyclone 24P will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  The tropical cyclone will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the northern part of an upper level ridge that extended from the Coral Sea to over Australia.  The upper level ridge will produce easterly winds that will blow toward the top of the tropical cyclone’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the shear will not be enough to prevent intensification.  Tropical Cyclone 24P will intensify during the next 24 hours.

Tropical Cyclone 24 P will move around the northwestern part of a high pressure system that is over the Coral Sea.  The high pressure system will steer the tropical cyclone during the next 24 hours.  On its anticipated track, Tropical Cyclone 24P will approach the coast of Queensland near Cairns in two days.

Tropical Cyclone 24P will bring strong winds and locally heavy rain to the coast of Queensland near Cairns.  Heavy rain could cause flooding in some locations.

Flood Watches are in effect for the parts of the Cape York Peninsula, the Central Coast, Capricornia, and Carpentaria catchments.

Tropical Cyclone Mitchell Moves Over Western Australia

Tropical Cyclone Mitchell moved over the coast of Western Australia south of Carnarvon on Monday.  At 10:00 a.m. EST on Monday the center of Tropical Cyclone Mitchell was located at latitude 25.8°S and longitude 114.2°E which put the center about 70 miles (110 km) south-southeast of Carnarvon, Australia.  Mitchell was moving toward the south-southeast at 11 m.p.h. (17 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.

The Australian Bureau of Meteorology issued a Warning that was in effect for the portion of the coast from Carnarvon to Overlander Roadhouse.  The Warning included Denham.

Tropical Cyclone Mitchell was the equivalent of a tropical storm at the time it moved over the coast of Western Australia.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Mitchell’s circulation.

A weather station in Carnarvon, Australia measured a sustained wind speed of 43 m.p.h. (69 km/h) and a wind gust of 63 m.p.h. (102 km/h).

Tropical Cyclone Mitchell will move around the southwestern part of a high pressure system that is over Australia.  The high pressure system will steer Mitchell toward the south-southeast during the next 24 hours.  On its anticipated track, Tropical Cyclone Mitchell will move inland over Western Australia.  The center of Mitchell’s circulation will pass east of Denham.

Tropical Cyclone Mitchell will bring gusty winds and locally heavy rain to the area between Denham and Overlander Roadhouse during the next few hours.  Heavy rain could cause floods in some locations.

Flood Watches are in effect for the Gascoyne River, the Avon River, the Moore River, the Hill River, the Greenough River, the Murchison River, the Wooramel River, the Linden-Minilya Rivers, and the Yarra Yarra Lakes District.

Tropical Cyclone Mitchell Passes Near Exmouth

Tropical Cyclone Mitchell was passing near Exmouth in Western Australia on Sunday morning.  At 10:00 a.m. EST on Sunday the center of Tropical Cyclone Mitchell was located at latitude 22.0°S and longitude 113.8°E which put the center about 25 miles (40 km) north-northwest of Exmouth, Australia.  Mitchell was moving toward the west-southwest at 9 m.p.h. (15 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.

The Australian Bureau of Meteorology issued a Warning that was in effect for the portion of the coast from Onslow to Overlander Roadhouse.  The Warning included Exmouth, Carnarvon, and Denham.  The Warning extended inland to include Gascoyne Junction.

Even though the center of Tropical Cyclone Mitchell remained offshore, Mitchell was producing strong winds along the coast of Western Australia.  A weather station at the Onslow airport measured a sustained wind speed of 59 m.p.h. (95 km/h) and a wind gust of 75 m.p.h. (120 km/h).

Tropical Cyclone Mitchell weakened on Saturday night even though the center of Mitchell remained over water.  Southeasterly winds blowing into the southwestern part of Mitchell’s circulation appeared to pull drier air from the interior of Western Australia into the western side of the circulation.  The drier air caused many of the thunderstorms in the southwestern part of Tropical Cyclone Mitchell to weaken.  Thunderstorms were still occurring in bands in the other parts of Mitchell’s circulation.  Since there were fewer thunderstorms near the center of Mitchell, those thunderstorms generated less upper level divergence.  Less upper level divergence meant that the thunderstorms pumped less mass away from the tropical cyclone.  The removal of less mass caused the surface pressure to increase.

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

Tropical Cyclone Mitchell will move through an environment that will be unfavorable for intensification during the next 24 hours.  Mitchell will move over water where the Sea Surface Temperatures are near 29°C.  However, it will move under the western end of an upper level ridge that is over Australia.  The upper level ridge will produce northwesterly winds that will blow toward the top of Mitchell’s circulation.  Those winds will cause the vertical wind shear to increase.  In addition, Tropical Cyclone Mitchell is likely to continue to pull drier air into its circulation.  The combination of more vertical wind shear and drier air will cause Tropical Cyclone Mitchell to weaken slowly during the next 24 hours.

Tropical Cyclone Mitchell will move around the western end of a high pressure system that is over Australia.  The high pressure system will steer Mitchell toward the south during the next 24 hours.  On its anticipated track, the center of Tropical Cyclone Mitchell will make landfall on the coast of Western Australia near Cape Cuvier and Carnarvon in 12 hours.

Tropical Cyclone Mitchell will bring strong winds and heavy rain parts of Western Australia near Cape Cuvier and Carnarvon.  Heavy rain is likely to cause floods in some locations.

Flood Watches are in effect for the Gascoyne River, the Ashburton River, the Fortescue River, the Greenough River, the Murchison River, the Wooramel River, the Pilbara Coastal Rivers, and the Yarra Yarra Lakes District.
