As of 2:00AM UTC tropical storm 03S, located approximately 90kilometers northeast of Karratha, Australia, the system has tracked southeastward at 45 km/h over the past 6 hours.Environmental analysis reveals the system lies in a marginal environment with warm (30°C) sea surface temperatures, low (10-15 knots) wind shear and robust poleward outflow into the base of a mid-latitude trough just to the west.Additional intensification to 50 mph (85 km/h) is still possible prior to landfall, as the upper-level outflow continues to provide robust exhaust, and prior to wind shear decapitating the system over land.However, once over land, the system will rapidly weaken due to terrain interaction and increasing wind shear, leading to dissipation of the system by 24 hours.The maximum significant wave height currently is 16 feet (4.9 meters).
