Tropical Storm Malou (10W), located approximately 110 nm south of Cheju Island, has tracked northward at 11 knots over the past six hours. Maximum significant wave height is 21 feet.

Animated infrared satellite (IR) imagery continues to show multiple low level vortices cyclonically rotating into the main area of deep convection.

IR satellite imagery, as well as two microwave passes, reveal a majority of the deep convection is being sheared to the northeast of the main low level circulation center (LLCC).

The current intensity is based on Dvorak estimates ranging from 35 to 45 knots. Upper level analysis shows enhanced poleward outflow associated with a mid-latitude trough to the north of the system.

TS 10W is currently tracking poleward along the western extent of a low-to mid level subtropical steering ridge. It is forecast to track across Cheju Island and intensify slightly due to favorable outflow conditions.

Near TAU 24, Malou will make landfall in southwestern South Korea and weaken as it begins to be absorbed into the baroclinic boundary. By TAU 48, TS 10W is forecast to complete extra-tropical transition.
