December 7: Northeast Monsoon is expected to revive in next 24 hours over South India. According to Skymet Meteorology Division in India, initially rains will be confined to coastal parts of Tamil Nadu and adjoining region of Kerala only. Thereafter it will gradually pick up strength and would give rain over entire Kerala, interior parts of Tamil Nadu and South Interior Karnataka during the next two to three days.
With the increase in rain activity, maximum temperature over the region is also expected to drop. The minimum temperature will however, remain unchanged.
The southern peninsula had been witnessing dry weather conditions for the past few days.
In last one week, Tamil Nadu received 20.9 mm of rain against the week’s normal average of 26.7 mm.
As we enter into the last phase of the Northeast Monsoon, it may be the last revival. Post this, the monsoon will start withdrawing itself and gradually move further south towards Sri Lanka, leaving the Indian coast.
Northeast monsoon usually remains active in the first fortnight of December, causing decent rains in Tamil Nadu, Kerala, South interior Karnataka, Rayalaseema and coastal Andhra Pradesh. After the first fortnight of December, rainfall reduces drastically over these regions. Extreme southern parts of Kerala and Tamil Nadu will still receive some rain. However, by third week, the peninsula hardly experiences any rain.
