Climate & Weather Industry & Economy - Climate & Weather Outer cloud bands of depression touch base Vinson Kurian
Thiruvananthapuram , Nov. 21 THE outer cloud bands of the tropical depression over southwest Bay of Bengal on Monday toyed with the peninsular coast along an arc extending from south Tamil Nadu to south coastal Andhra Pradesh, bringing moderate to heavy rainfall in the two States. The centre of the depression was located about 400 km southeast of Pamban at 8.30 a.m. on Monday, after the system swerved from its projected westward progression to curl overnight a little to the north, said Dr K.J. Ramesh of the National Centre for Medium Range Weather Forecasting (NCMRWF). In its update on Monday, the NCMRWF said the depression continued to move slowly to the west-northwest over the past 24 hours. It is likely to move further west-northwest in the coming days. The prevailing shear zone has thrown up a feeble cyclonic circulation over the southeast Arabian Sea, which continued to persist on Monday. The soggy ground conditions and the intermittent rain/thundershowers expected to punctuate the morning in Chennai on Tuesday could probably wash out the third one-day international between India and the touring South Africans, Dr Ramesh said, replying to a specific question. Sri Lanka also witnessed some heavy precipitation as the outer cloud bands of the massive system caressed its coast, but the bands had proceeded later to concentrate over the coastline along south Tamil Nadu and south coastal Andhra Pradesh. The centre of the system was still out into the sea, some 400 km southeast of Nagapattinam but nestled largely along the Sri Lankan latitudes on Monday morning. The prevailing conditions are conducive for the depression to gain in strength with the convective cloud bands and squally weather already covering the coastal districts of Tamil Nadu and south coastal Andhra Pradesh. In line with forecasts made already, a fresh spell of rainfall activity has been triggered along the coastal belt of Tamil Nadu and Pondicherry on Monday. During the coming days, widespread rains with heavy to very heavy falls are expected to extend into south interior parts of Tamil Nadu from the coast, while it will be scattered to fairly widespread over south coastal districts of Andhra Pradesh, Rayalaseema, Kerala and south interior Karnataka. Meanwhile, in a special weather bulletin, the Met Office, Chennai, said that the depression is likely to intensify further and move in a west northwesterly direction. Vedaranyam recorded a heavy rainfall of nine cm during the 24 hours ending 8.30 a.m. on Monday. The other chief amounts of rainfall recorded in cm are: Karaikal, Nagapattinam, Tiruthuraipoondi and Muthupet - five each; Chennai, Chennai Airport, Tambaram and Pattukottai - four each; Manamelkudi - three and Tiruvadanai, Tondi and Cholavaram - two each. In its forecast for the next five days, the NCMRWF said scattered to fairly widespread rains are likely in the Andaman and Nicobar Islands. The belt of widespread rain with isolated heavy falls is to extend over coastal and interior parts of Tamil Nadu initially and to Kerala and Lakshadweep subsequently. Scattered to fairly widespread rainfall activity is likely over south coastal districts of Andhra Pradesh, Rayalaseema and south interior Karnataka.
