Pre-Monsoon season is coming to an end, with just two days left. This year, the season has given a dismissal performance over most parts of South India. South Interior Karnataka is the only pocket to record good rains.
Although pre-Monsoon rains are going over Peninsular India for the last few days but intensity have remained light over most parts, particularly over Kerala. The north-south trough running through the region is primarily responsible of the rains over southern parts of the country during the season.
The trough has been active for last few days but has been giving heavy rains only over South Interior Karnataka. It would continue to give rains for the coming three to four days as well. As per the experts, mostly light rains with moderate at few places will be a sight in Alappuzha and Kochi. Coimbatore, Salem, Coonoor and Tirupur which is adjacent to Kerala might witness light rains with moderate at few places. However, Mysore, Chitradurga, Chamarajnagar and Hasan are expected to witness moderate to heavy rains.
Dismissal performance of pre-Monsoon season
Kerala is the rainiest place during the pre-Monsoon season, with May recording maximum rains in the coastal state. Unfortunately, this time the season have not performed up to the mark, with rains being well below the normal average.
Usually, as the Monsoon currents come around, rainfall activity supposedly picks up pace in South India. For now, South Interior Karnataka has performed the best wherein the pockets are witnessing heavy to moderate rains including capital city of Bengaluru. Looks like South Interior Karnataka is out from the deficit category and has come down to 19% from 30% as on May 27.
For the past one-week, moderate rains have been witnessed over Bengaluru, Hassan, Mandya and Chitradurga. On May 26, hailstorm activity was also observed in parts of Bengaluru. However, Kerala stands at rains deficiency of 54%. Similarly, Tamil Nadu is also large deficit by 66%.
The Southwest Monsoon 2019 had reached the Andaman and Nicobar Islands on May 18. However, it has yet not advanced much thereafter. Thus, in the absence of any active Monsoon surge, Kerala has not seen any pouring rains. Despite some rains over the state, the real taste of the Monsoon that Kerala witnesses is still missing. From last three to four days, no heavy rains have been seen.
As far as Tamil Nadu is concerned, Interior Tamil Nadu is witnessing more rains in comparison to Coastal Tamil Nadu. South Interior Karnataka is performing well as compared to coastal and north interior areas in Kerala, it is South of Kerala which is doing well in comparison to North Kerala.
Looks like these ongoing rains still would not help in bringing down the deficiency levels.
