Tropical Cyclone Tiffany strengthened east of the Cape York Peninsula on Sunday morning. At 7:00 a.m. EST on Sunday the center of Tropical Cyclone Tiffany was located at latitude 13.9°S and longitude 145.9°E which put it about 120 miles (190 km) north-northeast of Cooktown, Australia. Tropical Cyclone was moving toward the west at 9 m.p.h. (14 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 990 mb.
A Warning was in effect for the portion of the east coast of the Cape York Peninsula from Cape Grenville to Cape Tribulation. A Watch was in effect for the west coast of the Cape York Peninsula from Gilbert River Mouth to Mapoon.
A former Tropical Low east of the Cape York Peninsula strengthened quickly on Sunday morning and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Tiffany. More Thunderstorms developed near the center of Tiffany’s circulation. More thunderstorms also formed in bands revolving around the center of Tropical Cyclone Tiffany. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 70 miles (110 km) from the center of Tiffany.
Tropical Cyclone Tiffany will move through an environment favorable for intensification during the next 12 hours. Tiffany 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 centered east of Australia. The ridge will produce easterly winds that will blow toward the top of the Tropical Low’s circulation. Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification. The center of Tropical Cyclone Tiffany will pass near Cape Melville in 12 hours. If some of the circulation on the southern side of Tiffany passes over land, that could inhibit intensification.
Tropical Cyclone Tiffany will move north of a high pressure system over Australia. The high pressure system will steer Tiffany toward the west during the next 36 hours. On its anticipated track the center of Tropical Cyclone Tiffany will pass just north of Cape Melville in 12 hours. Tiffany will make landfall on the east coast of the Cape York Peninsula east of Coen within 24 hours. Tropical Cyclone Tiffany will bring gusty winds and locally heavy rain to northern Queensland. Heavy rain is likely to cause flash floods in some locations.
Elsewhere over the South Pacific Ocean, Tropical Cyclone 05P was spinning between Fiji and Vanuatu. At 4:00 a.m. EST on Sunday the center of Tropical Cyclone 05P was located at latitude 18.9°S and longitude 176.3°E which put it about 150 miles (240 km) west of Tavuki, Fiji. Tropical Cyclone 05P was moving toward the east-southeast at 13 m.p.h. (20 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.
