Live tracking map, satellite images and forecasts of Invest 97W in the Philippine Sea. High chance of development. Current wind speed 35km/h.
Satellite imagery shows a rapidly consolidating low-level circulation (LLC), with formative banding and low-level cloud lines wrapping into the center.
A 22/01:13 UTC ASCAT-C bullseye image shows a broad circulation, with patchy 35–45 km/h winds (20–25 knots) over the eastern quadrant and 10–20 km/h winds (5–10 knots) over the western semicircle.
Microwave imagery shows fragmented deep convective banding around the northern edge, with improved shallow banding wrapping into a broad center.
Analysis shows a marginally favorable environment with low to moderate (15–20 knots) wind shear offset by dual channel outflow. Sea surface temperatures are favorable at 30–31°C.
Invest 97W has formed along the eastern edge of an area of broad monsoonal flow and is expected to track poleward along the eastern edge of this complex system over the next 24 to 36 hours. After this period, the system may dissipate and merge with a developing monsoon depression south of Okinawa. This monsoon depression is forecast to produce an extensive swath of gale-fore winds along the eastern and northern edges.
