Chennai: It almost felt like the December deluge of 2015 yesterday when ghost rains struck the city without notice. The sky which was almost clear till the afternoon began to become darker and it poured heavily since evening. In some localities of Chennai, rains lasted for 12 hours without halt. This is not the end is what the Met department says, as it has warned that such heavy rains are likely to continue till Monday due to two depressions prevailing.
An official said, “Under the influence of the upper air cyclonic circulation over Sri Lanka and adjoining southwest Bay of Bengal, a low pressure area is persisting there. In addition, another low pressure area is persisting over Gulf of Siam and adjoining Malay Peninsula coast which likely to emerge into Andaman sea in 48 hours.”
“In the next 24 hours, heavy to very heavy rainfall is likely to occur at isolated places over south and north coastal Tamilnadu. Following this, moderate to light rains will continue till Monday if there is not any significant weather activity.
Strong winds will be blowing from northerly to northeasterly at 15-20 knots gusting to 25-30 knots occasionally. So, fishermen are advised to stay safe,” he added. DGP office recorded a maximum rainfall of 30 cm.
Speaking to reporters today, Regional Meteorological Department – Chennai ACWC Director S Balachandran said, “The low pressure was persisting over the same area which is the reason why we couldn’t predict yesterday’s rains on time. But after yesterday evening it witnessed a slight movement but not likely to gain strength.”
Since the low pressure area is persisting between Sri Lanka and the south coastal Tamilnadu, strong moist winds are blowing towards the south Tamilnadu and the north coastal Tamilnadu. So, many places will receive moderate rainfall while very heavy rainfall is likely to occur at isolated places in the next 24 hours.
