Invest 98 heeft nu al bijna stormkracht, maar nog niet de structuur van een tropische storm.
Maximum sustained surface winds are around 45–55 km/h (25–30 knots). Minimum sea-level pressure is estimated to be near 998 hPa.
Infrared imagery shows an area of disorganized but persistent convection.
Microwave imagery shows fragmented convective banding throughout the northern semicircle of the broad low-level circulation. A 28/15:25 UTC ASCAT-C bullseye image shows an elongated circulation center with 45–55 km/h winds (25–30 knots) displaced to the northeast and southwest of the defined circulation.
Analysis shows a marginally favorable environment for further development with good upper-level poleward outflow and warm sea surface temperatures of 28–29°C offset by high (30–40 knots) wind shear.
Global deterministic models are in fair agreement that Invest 99B will continue to slowly consolidate as it tracks poleward toward the east coast of India over the next 1 to 2 days.
