Kolkata rains

Kolkata has been receiving moderate to heavy rains for the last week. The heaviest downpour in excess of 100mm (144mm) was observed on 16th June and followed by moderate showers (60mm) on 17th June. Total for the month of June for Kolkata stands at 365mm against the monthly normal of 300.6mm.

Two weather systems are affecting weather for the last few days and this is likely to continue for the next 3 days. There is a low-pressure area over Southeast Uttar Pradesh and Bihar and also a cyclonic circulation over Bangladesh. Together this duo is causing rainfall over Kolkata and suburbs leading to surplus monthly rainfall.

Kolkata has a record of measuring 419.7mm monthly rainfall in June 2018. This 10 years record for Kolkata looks to be on the threshold of creating a new milestone. The year 2013 and 2020 for Kolkata also reached very close to the figure of 400mm but just fell short. The year 2021 is likely to be the 2nd one in the last 10 years to cross the 400mm mark for Kolkata and has a chance to create a new record.

A fresh weather system is expected to form over Gangetic West Bengal on 23rd June. This cyclonic circulation will get organized over West Bengal and adjoining Bangladesh in the subsequent 48 hours. The system will meander over the same area with a slight shift and cause moderate rain and thundershowers between 23rd and 29th June. Most of the weather activity will happen during the evening and night. With this wet spell, Kolkata is expected to cross the mark of 400mm and possibly set a new milepost.
