Weak Pre-Monsoon Activity Over South Peninsula, Moderate Showers For Kerala

Pre-monsoon activity over the South Peninsula has gotten poorer for the last few days. The complete homogenous region of South India, as such, is surplus so far. Between 01st March and 21st April, South Peninsula has an excess of 76% rainfall.

All the subdivisions, including Kerala, Tamil Nadu and Karnataka, have recorded huge surpluses till halfway through the pre-monsoon season. Tamil Nadu and Karnataka have a large excess of over 100 % during this period.

However, the weather activity is likely to slow down during this week and remain mostly confined to Kerala.

Despite the reduction of rainfall over the last few days, the temperatures have remained under check. Telangana was the hottest pocket of South India, with temperatures in excess of 43°C at Nizamabad, Adilabad and Medak.

Mercury breached 40°C in Andhra Pradesh at Karnool, Nandyal, Tirupathi, and Cuddapah. However, the extreme heat went missing from the region.

The state of Tamil Nadu shied away from 40°C, and stations like Madurai, Thanjavur, and Salem recorded a day maximum of 39°C. 

The capital city of Chennai and its suburbs were restricted to 35-36°C.  The north-south stretch of Kerala was further down, and mercury could just reach around 34°–35°C.

Kochi, Kozhikode, Cannur, Wayanad, Punalur, Alappuzha and Thiruvananthapuram remained at 35°C or less.

Thrissur, Cochin, Punalur and the capital city Thiruvananthapuram were the few cities that received light showers in the previous 24 hours.

The pre-monsoon Peninsular India trough is marked from Telangana to the border areas of South Tamil Nadu and Kerala. The trough is more inclined towards Kerala than Tamil Nadu. The northern half of the trough across Karnataka and Telangana is not very active.

However, the entire north-south-oriented state of Kerala will have scattered pre-monsoon showers over the next 4-5 days. Rain and thunderstorm activity will extend from Kasaragod-Kudlu in the north to Thiruvananthapuram-Varkala in the south.

Light to moderate showers will run through Kannur, Wayanad, Kozhikode, Thrissur, Ernakulam, Alappuzha and Kollam.

The trough is likely to oscillate east-west over the interiors of Peninsular India during the week. Isolated weather activity can not be ruled out over some parts of Rayalaseema, South Interior Karnataka, and interior Tamil Nadu. 

Light to moderate showers are likely over Hyderabad, Kurnool, Anantapur, Bengaluru, Mysuru, Coimbatore, Erode, Salem, Kodaikanal and Ooty during 26th and 30th April. Most of the weather activity is expected during evening and early night hours.
