Pre-monsoon showers in South India usually begin in the month of March, which is the case right now. However, these showers have been confined to certain regions and are not widespread. Pre-monsoon showers depend on three factors: low level trough in peninsular India, easterly wave and wind discontinuity.
For the last two days Kerala has been observing pre-monsoon showers, while the interior parts and Tamil Nadu have been experiencing minimal weather activity. In the last 24 hours, from 8.30 am on Monday, Alappuzha has recorded 26.8 mm of rain, Kottayam 29.1 mm and Thiruvananthapuram 2.8 mm. Kerala will continue to observe patchy isolated rain for another 48 hours.
But the interior parts like Rayalaseema and Telangana have been experiencing very warm conditions due to absence of weather activity. Rayalaseema is the hottest region at the moment. Anantapur recorded 38.5°C as the day temperature on Monday. Kurnool and Tirupati recorded 38°C and 337.4°C as the maximum, respectively.
Day temperatures in Telangana are also exceeding 36°C. For instance Nizamabad recorded 36.6 degrees Celsius as the maximum temperature on Monday, while the day temperature settled at 36°C in Hyderabad.
The temperatures along the west coast are warmer than the east coast and are settling between 34°C and 36°C. In the east coast the day temperatures are hovering around 33°C, which is almost two degrees lower than that in the west coast.
The warm condition in the region is going to prevail for at least another 2-3 days as there isn’t any system in sight. Kerala will however, continue to observe some rain for the next 48 hours.
