Increasing westerly shear and a drying airmass along the forecast
track should result in weakening within 36 to 48 hours, and global
models show the cyclone dissipating by 60 h. However, given the
small size of the system, it wouldn't be surprising if the cyclone
weakened or dissipated sooner than shown here.
