The low pressure area formed in Bay of Bengal continues to move westward. This system has already given moderate to heavy rainfall over Andaman and Nicobar Islands during the initial days of its formation.
At present, this weather system is marked over west central Bay of Bengal and adjoining equatorial Indian Ocean. It is expected to continue moving in west direction toward Sri Lanka and adjoining Tamil Nadu Coast.
So, the system will start giving moderate to heavy rains over Sri Lanka by tonight. In fact, few extremely heavy spells are also likely over the region, leading to possible flash floods and landslides.
Weathermen at Skymet Weather expect South Tamil Nadu to witness moderate to heavy showers during the next 24 hours. In fact, the coastal regions including Chennai will also observe light to moderate rains. However, the interior districts of the state will only get to see scattered light rainfall activity with one or two moderate showers.
Meanwhile, southern parts of Kerala are expected to record few moderate to heavy showers around November 27. These on and off rains will continue till November 28 over many places of Tamil Nadu and Kerala.
The rain belt is also anticipated to cover parts of South Interior Karnataka including Bengaluru. The region will witness light intensity showers.
We can expect significant reduction in the rainfall activity over the entire Tamil Nadu, Kerala and Sri Lanka around November 29.
