Peninsular India recorded the highest ever rainfall in November since 1901, said the India Meteorological Department while noting that even the ‘heavy’, ‘very heavy’ and ‘extremely heavy’ rainfall events last month were the highest over the last five years.
Andhra Pradesh, Tamil Nadu, Puducherry, Kerala and south interior Karnataka received 169% excess rainfall last month while the country witnessed 645 ‘heavy’ (64.5 to 115.5 mm), 168 ‘ve heavy’ (115.6 to 204.5 mm) and 11 ‘extremely heavy’ (over 204.5 mm) rainfall events in November.
The meteorological department attributed such rainfall events to the active phase of northeast monsoon and also to five low-pressure systems over the Andaman Sea in November which was nearly double the average number of low-pressure systems in the month.
Predicting monthly rainfall forecast, the IMD said the monthly rainfall over the south peninsular India consisting of five meteorological subdivisions—Tamil Nadu, Puducherry & Karaikal, Coastal Andhra Pradesh & Yanam, Rayalaseema, Kerala & Mahe and South Interior Karnataka—is most likely to be above normal(>132% of Long Period Average) during December.
Besides, the cyclonic storm ‘Jawad’ is also likely to hit north Andhra Pradesh and Odisha coast on December 4 morning, bringing heavy rainfall to the region.
