Tropical Cyclone Trevor developed over the Coral Sea on Sunday. At 5:00 p.m. EDT on Sunday the center of Tropical Cyclone Trevor was located at latitude 13.2°S and longitude 146.1°E which put it about 190 miles (305 km) east of Lockhart River, Australia. Trevor was moving toward the south-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 956 mb.
The circulation around a low pressure system over the Coral Sea organized quickly on Sunday and the Australian Bureau of Meteorology designated the system as Tropical Cyclone Trevor. An inner rainband wrapped around the center of circulation and there were indications that an eye could be starting to form. Bands of showers and thunderstorms were developing in all parts of the Tropical Cyclone Trevor and the circulation was symmetrical. Storms near the center of Trevor were generating upper level divergence which was pumping mass away from the tropical cyclone in all directions.
Tropical Cyclone Trevor will move through an environment favorable for intensification during the next 24 to 36 hours. Trevor will move over water where the Sea Surface Temperature is near 29°C. It will move through an area where the upper level winds are weak and there will be little vertical wind shear. Trevor will intensify during the next day or so and it could intensify rapidly. It is likely to strengthen into the equivalent of a hurricane/typhoon.
Tropical Cyclone Trevor will move around the northwestern portion of a subtropical ridge. The ridge will steer Trevor toward the west-southwest. On its anticipated track Tropical Cyclone Trevor could reach the east coast of the Cape York peninsula in about 36 hours. Trevor could be the equivalent of a hurricane/typhoon by that time.
The Australian Bureau of Meteorology has issued a Tropical Cyclone Warning for the portion of the coast from Cape Grenville to Cape Flattery. Tropical Cyclone Watches are in effect for the portions of the coast from Cape York to Cape Grenville and from Cape Flattery to Cape Tribulation.
