Tropical Storm Malou (10W) is located approximately 320 nm south of Cheju Island, and has tracked north-northwestward at 15 knots over the past six hours. Maximum significant wave height is 16 feet.

Animated infrared satellite imagery shows increased deep convection developing over the low level circulation center (LLCC) with low level banding wrapping into the system from the northwest and southeast.

The imagery and the convective asymmetry of the system indicate stronger winds along the eastern flank of the system associated with the tight pressure gradient. Current intensity is about 35 knots, with 25 to 30 knot winds at the system center.

Upper level analysis reveals TS10W is in a region of enhanced diffluence aloft associated with its proximity to the diffluent region of the upper level low over Taiwan. The system is currently tracking along the southwestern periphery of a western extension of a low to mid-level steering ridge.

Malou is forecast to continue tracking north-northwestward through TAU 36, then begin to turn poleward as an approaching mid-latitude trough erodes the ridge. The system is forecast to gradually intensify through TAU36, then weaken as it interacts with the mid-latitude westerly flow near TAU 48. The system is expected to make landfall south of Seoul, South Korea, and rapidly weaken as it becomes absorbed into the baroclinic boundary.
