Several parts of the State oare likely to experience dry weather for two more days.
The low pressure that formed over the Andaman sea was over the islands on Wednesday. An associated cyclonic circulation also persists. According to the IMD, the system is likely to become more marked over southwest Bay of Bengal and the neighbourhood around November 26.
Officials of the meteorological department note that the system is still far away and it is being monitored for revival of monsoon. With the dry spell prolonging for more than a week now, the State’s seasonal rainfall has fallen short by 18% against its average. Tamil Nadu has received 26.4 cm against its quota of 32.1 cm so far this season, causing concern of rainfall deficit. However, officials note that the winter monsoon may bridge the shortfall even with one intense rain spell.
S. Balachandran, Director, Area Cyclone Warning Centre, said “We will wait till Friday for better clarity of the weather system and monitor its movement. As of now, we can expect moderate showers in southern Tamil Nadu and heavy rainfall in one or two places.”
The northeast monsoon may get more active towards the weekend. The department forecast that the coastal parts of the State and Puducherry may begin to get fairly widespread rainfall from Sunday. A few places may even experience heavy rain spells on Sunday.
Another low pressure
The department expects another low pressure area likely to form over southeast Bay of Bengal around November 27. Chennai needs another 10 cm to touch its annual average rainfall.
The meteorological department forecast that Chennai may have light rain in some areas till Friday and the maximum temperature may be around 32 degree celsius.
