Live tracking map, satellite, radar, and forecasts of Invest 90B near Sri Lanka. High chance of development. Current wind speed 55km/h.
Maximum sustained surface winds are around 50–60 km/h (27–32 knots). Minimum sea-level pressure is estimated to be near 999 hPa.
Recent infrared imagery show a consolidating low-level circulation center (LLCC) obscured by persistent convection. Furthermore, a MetOp-C ASCAT pass shows a patch of 55 km/h winds (30 knots) along the western edge and 45 km/h winds (25 knots) along the northern edge of the system.
The environment is favorable for development moving forward, with a strong poleward outflow channel and warm (28–29°C) sea surface temperatures.
The main hindrance being the moderate to high (20–25 knots) wind shear that could limit intensification by tilting the structure of the system and disrupting deep convection.
Both deterministic and ensemble models agree on a northwest track toward Sri Lanka over the next 2 days, with the ECMWF ensemble especially, predicting quicker and more intense development of 90B.
Deterministic models remain reluctant to intensify the system beyond 65 km/h (35 knots).
