Rain pours like cloudburst; meteorological experts say rain likely to abate
Kochi: The studies regarding the monsoon in Kerala had showed that the decline in rainfall is mostly experienced in Wayanad. The experts who analysed the records of past 120 years found that the tendency of rain decline is mostly seen in this district.
Up to 20-30 percent decline was observed in the rainfall in Wayanad. The heavy rain resulted from the depression formed in Odisha coast and monsoon wind from the Arabian sea wreaked havoc here this time.
CUSAT (Cochin University of Science and Technology) Radar Centre Associate Director Dr. S. Abhilash pointed out that a cloudburst-like downpour is happening presently. The cloud thickness is rather high and it brings down huge amount of rain.
There is a huge difference between 10 cm rainfall in a day and 10 cm rain within two hours. When heavy rain lashes in eco-sensitive areas, it causes landslip. The disaster in Wayanad was the result of this phenomenon.
CUSAT Radar Centre scientist Dr. M. G. Manoj said that the rain will be weakened in the coming days. The presence of thick clouds has reduced. Two large cyclones have formed in the Western Pacific Ocean. This is likely to take away the clouds from here, he said.
Rain to abate after Saturday
Dr. Abhilash said that the present incidents shouldn't be compared with the flood of previous year. Heavy downpour occurred two times last year. Huge rain poured down on August 8, 9 and 10 and later on August 14 and 15. Presently, the rain is likely to decrease after Saturday.
Downpour is likely to take place in south Kerala and coastal regions on August 14 and 15. Rain was very less in June and July this time. All the dams opened were smaller ones and as of now, water level in larger ones has not reached the storage capacity.
