Invest 90B

Last Modified:

Satellite images, weather maps and tracks of 90B, January 24 - February 2. Max wind speed 55km/h.

Invest 90B has a low chance of formation in the next 24 hours.

Infrared and microwave images show flaring deep convection being sheared to the northwest and disorganized low level cloud lines.

Analysis shows marginally favorable conditions for intensification as indicated by moderate (15-20 knots) wind shear and increasing land interaction with Sri Lanka partially offset by good poleward and westward outflow and warm (28-29°C) sea surface temperatures.

Forecast models are in agreement that 90B will continue west-southwestward and make landfall over Sri Lanka in around 24 hours after which the Invest is forecast to dissipate.

Surface winds are around 45-55 km/h (25-30 knots). Minimum sea-level pressure is near 1002 hPa.
