Erstwhile cyclone Fengal weakens as well-marked ‘low’, but continues to pour it down over interior Tamil Nadu

Erstwhile rain-spewing cyclone Fengal has weakened three times over to a well-marked low-pressure area but was spotted hovering over north interior Tamil Nadu after making a calamitous landfall near Puducherry

Weakening has not made much impact on its rain-making capacity as it poured down extremely over Tamil Nadu, Puducherry & Karaikal and very hover over Kerala & Mahe during the 24 hours ending 8.30 am this (Monday) morning.

Raining in the hills

India Meteorological Department (IMD) gave out significant rainfall amounts (in cm) recorded during this period over Tamil Nadu as Yercaud (24); Dharmapuri (16); Salem (6); and in Kerala & Mahe at Kottayam (18); Cochin (CIAL) airport-15; and Kozhikode-7. 

This followed record-breaking spells triggered by it while being a cyclone and its gradual weakening to a deep depression and depression through Sunday before being categorised as a well-marked ‘low’ today. These included an outrageous 50 cm-plus spell over Puducherry creating a 30-year record for a 24-hour-spell and a number of other 40-50 cm spells in the neighbourhood.

Propelling into interior TN

Meanwhile, satellite pictures at 10.30 am this morning indicated moderate to heavy rain is being recorded over the Tamil Nadu-Karnataka border over an area bounded by Kanakapura, Gobichettipalayam, Mettur, Pennagaram and Denkanikottai.
