As the remnants of Cyclone Bulbul have moved away, northeasterly humid winds are setting in along the East Coast. These winds are strengthing gradually. Moreover, a Trough is extending from Sri Lanka up to Southeast Andhra Pradesh Coast in the lower levels. Also, the flow of northeasterlies could be seen along the South of Kerala Coast. Hence, rainfall activities will pick up pace along the Tamil Nadu Coast, South Andhra Pradesh Coast. A few moderate spells are also likely here. However, Kerala and Karnataka will observe a reduction in rainfall activities during the next 24 to 48 hours. Scattered rains are likely in the southern parts of Telangana and Rayalaseema.

Moderate to heavy intensity rain is expected in Tamil Nadu and Kerala for the next 24-48 hours. The southern districts of both the states will face the major action of the Northeast Monsoon in terms of rain. There are also chances of heavy to very heavy rain in Lakshwadeep during this period. South Interior Karnataka is also one region where people can observe good rainfall activity.
The rainfall activity in the region would largely be a result of the well-marked low-pressure area in the Comorin region and South Sri Lanka coast. This system will move in a northwest direction and is likely to intensify into a depression tonight or tomorrow in the southeast Arabian Sea. In fact, there is a high probability of the system intensifying further into a deep depression. So we can say that the Northeast Monsoon is going to remain active for at least the next three days in the region of Tamil Nadu and Kerala.
