Fairly widespread showers have formerly occurred over the southern districts of Tamil Nadu along with scattered rains of light intensity over the remaining pockets including the capital city Chennai. The good news is that these showers would now pick up pace again.
In a span of 24 hours from 08:30 am on Monday, Pamban recorded a good amount of 52 mm, followed by Karaikal 42 mm, Tondi 9 mm, Tiruchirappalli 6 mm, Kanyakumari 5 mm, Madurai 5 mm, Palayamkottai 4 mm, Nagapattinam 4 mm, Salem 3 mm and Coonoor 2 mm.
At present, the well-marked low-pressure area is over Southwest Bay of Bengal and is most expected to move in the westerly direction towards the Tamil Nadu Coast.
As a result, we can expect rains to increase significantly over the state; in particular, Chennai shall record a few intense spells of rain. This spell would be after an elongated gap over the Detroit of India.
There is a strong likelihood that intermittent showers would persist over many parts of Tamil Nadu during the next 24 hours. As the system would continue to move in westerly direction, the intensity of rains would gradually increase over the interior parts of the state thereafter. In contrast to this, the coastal stations may follow the subsiding tendency.
By November 23, weathermen foresee a significant decrease in rainfall over the entire state of Tamil Nadu which could be attributed to the westerly movement of the well-marked low-pressure area. However, this system would give few spells over South Interior Karnataka and Kerala.
