Tropical Cyclone Kirrily Brings Wind and Rain to Queensland

Tropical Cyclone Kirrily brought wind and rain to northern Queensland on Thursday. At 10:00 a.m. EST on Thursday the center of Tropical Cyclone Kirrily was located at latitude 19.6°S and longitude 145.6°E which put it about 70 miles (110 km) west of Townsville, Australia. Kirrily was moving toward the west-southwest at 22 m.p.h. (35 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 993 mb.

A Warning was in effect for the portion of the coast from Innisfail to Ayr. The Warning included Townsville.

The center of Tropical Cyclone Kirrily made landfall on the coast of Queensland just to the north of Townsville on Thursday. Kirrily strengthened up until it made landfall. Tropical Cyclone Kirrily was almost the equivalent of a hurricane/typhoon at the time of landfall. The inner end of a rainband wrapped around the center of Kirrily’s circulation and an eye was starting to form just before landfall occurred. Winds to tropical storm force extended out 200 miles (320 km) from the center of Tropical Cyclone Kirrily at the time of landfall.

A weather station at Townsville reported a sustained wind speed of 38 m.p.h. (61 km/h) and a wind gust of 58 m.p.h. (93 km/h). The weather station reported 0.97 inches (24.6 mm) of rain. A weather station at Lucinda reported a sustained wind speed of 51 m.p.h. (82 km/h) and a wind gust of 62 m.p.h. (100 km/h). A weather station at Alva Beach reported a sustained wind speed of 49 m.p.h. (80 km/h) and a wind gust of 67 m.p.h. (108 km/h). That weather station also reported 1.13 inches (28.8 mm) of rain.

Tropical Cyclone Kirrily will move around the northwestern part of a high pressure system over the Coral Sea. The high pressure system will steer Kirrily toward the west-southwest during the next 24 hours. On its anticipated track, Tropical Cyclone Kirrily will continue to move inland over northern Queensland. Kirrily will weaken gradually as it moves farther inland. Kirrily will bring gusty winds and locally heavy rain to northern Queensland. Heavy rain could cause floods in some locations. A Flood Watch was in effect for the region between Tully and Airlie Beach.

A former tropical depression strengthened to Tropical Cyclone Ana over the Mozambique Channel on Sunday. The inner end of a rainband wrapped around the northern side of the center of Ana’s circulation on Sunday evening. Other bands of showers and thunderstorms were revolving around the center of circulation. The strongest thunderstorms were occurring in bands in the northern and western parts of Ana. Bands in the southeastern part of the circulation consisted primarily of showers and lower clouds. The air in that part of Tropical Cyclone Ana had passed over Madagascar and may have been sinking. Storms near the center of Ana generated upper level divergence that pumped mass away to the west of the tropical cyclone. Winds to tropical storm force extended out 160 miles (260 km) from the center of circulation.

Tropical Cyclone Ana will move through an environment favorable for intensification for the next few hours. Ana will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the northwestern part of an upper level ridge over the Southwest Indian Ocean. The ridge will produce easterly winds that will blow toward the top of the circulation. Those winds will cause some vertical wind shear, but the wind shear will not be strong enough to prevent intensification. Ana could get stronger before it reaches the coast of Mozambique on Monday.

Tropical Cyclone Ana will move around the northern side of a high pressure system over the Southwest Indian Ocean. The high pressure system will steer Ana toward the west during the next 36 hours. On its anticipated track the center of Tropical Cyclone Ana could make landfall on the coast of Mozambique near Angoche in a few hours. Ana will bring gusty winds and locally heavy rain to northern Mozambique, southern Malawi and northern Zimbabwe. Heavy rain could cause flash floods in some locations. Tropical Cyclone Ana could cause a storms surge of up to six feet (2 meters) along the northern coast of Mozambique.

The center of Tropical Cyclone Chalane made landfall on the coast of northeast Madagascar between Fenoarivo and Toamasina on Saturday. The maximum sustained wind speed was 45 m.p.h. (75 km/h) at the time of landfall. Winds to tropical storm force extended out 90 miles from the center of the tropical cyclone. The heaviest rain was falling in bands in the western and southern parts of Chalane.

Tropical Cyclone Chalane will move west-southwest across central Madagascar during the next 24 hours. The center will pass a little north of Antananarivo. The mountains will disrupt the lower levels of the circulation and Chalane will weaken while it is over land. However, Tropical Cyclone Chalane will drop heavy rain over parts of central and northern Madagascar. The rain will be heaviest where winds push air up the slopes and flash floods could occur in regions of steep terrain.

Tropical Cyclone Chalane will move over the Mozambique Channel in a day or so. If the middle and upper parts of the circulation remain relatively intact, then Chalane could strengthen back into the equivalent of a tropical storm. Tropical Cyclone Chalane or the remnants of its circulation could approach Mozambique in 72 hours

Tropical Cyclone Chalane Swirls Toward Madagascar

Tropical Cyclone Chalane swirled toward Madagascar on Friday. At 4:00 p.m. EST on Friday the center of Tropical Cyclone Chalane was located at latitude 16.2°S and longitude 53.3°E which put it about 240 miles (390 km) east of Mananara, Madagascar.

The circulation around Tropical Cyclone Chalane exhibited more organization on Friday, but the it was still asymmetrical. The strongest thunderstorms were still occurring in bands in the southern half of the circulation. Bands in the northern half of Chalane consisted primarily of showers and lower clouds. The strongest winds were occurring in the bands south of the center of circulation. Winds to tropical storm force extended out 100 miles (160 km) on the south side of Tropical Cyclone Chalane. Winds to tropical storm force only extended out 25 miles (40 km) on the northern side of Chalane.

Tropical Cyclone Chalane will move through an environment favorable for intensification during the next 24 hours. Chalane will move over water where the Sea Surface Temperature is near 28°C. It will move under the northern side of an upper level ridge over the Southwest Indian Ocean. The ridge will produce easterly winds which will blow toward the top of the tropical cyclone. Those winds will cause moderate vertical wind shear and they will inhibit intensification. However, the winds will not be strong enough to prevent Tropical Cyclone Chalane from intensifying during the next 24 hours.

Tropical Cyclone Chalane will move north of a high pressure system over the Southwest Indian Ocean. The high will steer Chalane toward the west during the next several days. On its anticipated track Tropical Cyclone Chalane will approach northern Madagascar in about 24 hours. Tropical Cyclone Chalane will bring gusty winds and locally heavy rain to parts of northern Madagascar. Heavy rain could cause flash floods in some locations.

The minimum surface pressure was 996 mb.

The circulation around a low pressure system northeast of La Reunion strengthened on Thursday and the system was designated at Tropical Cyclone Chalane. The circulation around Chalane was still organizing. The distribution of thunderstorms around Tropical Cyclone Chalane was asymmetrical. The strongest thunderstorms were occurring in bands southeast of the center of circulation. The strongest winds were occurring in those rainbands. Bands in other parts of Chalane consisted primarily of showers and lower clouds. Storms southeast of the center of circulation generated upper level divergence which pumped mass away to the south of the tropical cyclone.

Tropical Cyclone Chalane will move through an environment favorable for intensification during the next 36 hours. Chalane will move over water where the Sea Surface Temperature is near 28°C. It will move under the western end of an upper level ridge over the South Indian Ocean. The ridge will produce northerly winds which will blow toward the top of the tropical cyclone. Those winds will cause moderate vertical wind shear and they will inhibit intensification during the next 12 hours. Chalane will move into an area where the upper level winds will be weaker on Friday and it could strengthen more.

Tropical Cyclone Chalane will move south of a high pressure system over the South Indian Ocean. The high will steer Chalane toward the west during the next several days. On its anticipated track Tropical Cyclone Chalane will pass north of Mauritius and La Reunion. Chalane could approach northern Madagascar in about 48 hours. Tropical Cyclone Chalane will bring gusty winds and locally heavy rain to parts of northern Madagascar. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Claudia Strengthens to Equivalent of Hurricane/Typhoon

Tropical Cyclone Claudia strengthened into the equivalent of a hurricane/typhoon over the South Indian Ocean northwest of Australia on Sunday.  At 4:00 p.m. EST on Sunday the center of Tropical Cyclone Claudia was located at latitude 16.0°S and longitude 117.9°E which put it about 290 miles (465 km) north of Port Hedland, Australia.  Claudia was moving toward the west-southwest at 25 m.p.h. (40 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 971 mb.

Tropical Cyclone Claudia strengthened over the warm water northwest of Australia on Sunday.  A small 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.  Bands of showers and thunderstorms were revolving around the core of Claudia.  The stronger rainbands were in the western half of the circulation.  Bands in the eastern half of the circulation consisted primarily of showers and lower clouds.  Storms near the core of the circulation were generating upper level divergence which was pumping mass away to the west of the tropical cyclone.  Winds to hurricane/typhoon force extended out 20 miles (30 km) from the center of circulation.  Winds to tropical storm force extended out 100 miles (160 km) from the center.

Tropical Cyclone Claudia will move through an environment favorable for intensification during the next 24 hours.  Claudia will move over water where the Sea Surface Temperature is near 30°C.  It will move around the northwestern part of an upper level ridge centered over Australia.  The ridge will produce easterly winds which will blow toward the top of the tropical cyclone.  Those winds will produce moderate vertical wind shear.  The wind shear will slow the rate of intensification, but the shear will not be strong enough to prevent Claudia from getting strong during the next 24 hours.

Tropical Cyclone Claudia will move around the northwestern side of a high pressure system over Australia.  The high will steer Claudia toward the west-southwest.  On its anticipated track the core of Tropical Cyclone Claudia will remain well off the coast of Western Australia.
