Dissipation and Effects :
- During the course of propagation of the severe cyclone over the land, it will gradually weaken, shedding heavy amount of rainfall over the region.
- On November 15, the rainfall intensity will increase gradually at most places and it will be heavy to very heavy at a few places and extremely heavy (above 20 cm) at isolated places over north Tamil Nadu.
- Squally wind speed reaching 45-55 kmph, gusting to 65 kmph is likely to commence along and off north Tamil Nadu–south Andhra Pradesh coasts from November 14 morning.
