The southern parts of the country have seen the arrival of the Northeast Monsoon, but the onset has been a mild one. Moreover, last week was a very poor one for the region with almost no rains over the region.
Now rains are likely to make an appearance over the southern parts of the country. On October 26th and 27th, very light rains will be seen in parts of Tamil Nadu with moderate rains in isolated pockets of Kerala.
Both the intensity and spread will increase from October 28th over the states of Tamil Nadu and Kerala. These rains may spill over to South interior Karnataka as well.
The reason for these rains can be attributed to a cyclonic circulation which is in the southwest Bay of Bengal in the lower levels. A feeble trough is also extending along the Tamil Nadu coast. Another feeble trough is extending from Kerala to Coastal Karnataka.
While we do not expect heavy rainfall activity over any of these areas, it will definitely be a welcome change from the poor Northeast Monsoon week that the states saw last week.
