Invest 98W

Live tracking map, satellite, radar, and forecasts of Invest 98W near Vietnam. High chance of development. Current wind speed 35km/h.
Maximum sustained surface winds are around 35–45 km/h (18–23 knots).
Infrared imagery shows a broad area of disorganized deep convection associated with a slowly consolidating low-level circulation center (LLCC).
The LLCC remains broad and elongated, with the western extent of the circulation likely extending over land. Current analysis of the surrounding environment shows favorable conditions for further consolidation with low (5–10 knots) wind shear, strong equatorward outflow aloft, warm (28–29°C) sea surface temperatures, and sufficient moisture throughout the air column.
Global deterministic models are in good agreement that 98W will move generally northwestward, skirting the coast of Vietnam, potentially reaching tropical depression criteria during the next 12 to 24 hours.
There remains significant uncertainty as to whether the broad system can organize before it makes landfall in Vietnam and transits inland.
