While most of Chennai is worried about possible Low Pressure / Depression / Cyclone heading for the metropolis next week there is an immediate threat to parts of South Tamil Nadu as an intensifying low pressure area is expected to graze the coasts of the state in the Southern fringes along with parts of South Kerala as it heads towards Arabian Sea over the next 48 hours or so.
This Strong “Low Pressure” currently lies SSE of Sri Lanka and is expected to move in a Northwest Direction over the Comorin Sea and subsequently surfacing over Arabian Sea around Thursday evening / midnight. As it travels in its path there is high confidence among models it would graze parts of South Tamil Nadu along the coasts of Kanyakumari district and adjoining areas of Thiruvananthapuram district of South Kerala bringing heavy winds and heavy spells of rains at times.
The rains are likely to increase from today late evening / night and continue till tomorrow afternoon during which time parts of Kanyakumari & Tirunelveli districs and places along the Western Ghats up to possibly parts of Coimbatore district could record heavy to very heavy spells of rains in a few places. Most of Tamil Nadu is likely to receive rains as the system moves Northwest and brings with it stronger moisture filled Easterlies from the Bay of Bengal.
