excess rain

Weather Update, March 28: According to the India Meteorological Department (IMD), the states of Meghalaya and Assam have received excess rain while Arunachal Pradesh, Manipur, Mizoram, and Tripura have remained dry in the northeast with deficient rainfall so far this month.

This is concerning as the northeast region is highly dependent on agriculture, which relies heavily on regular rainfall.

The IMD data shows that Meghalaya has received 125 mm of rainfall this month, which is 153% above normal while Assam has recorded over 75 mm of rainfall, which is 43% above normal.

However, over 81 mm of rainfall was recorded in Arunachal Pradesh, which is 40% below normal, 27 mm in Manipur (34% below normal), 28 mm in Mizoram (39% below normal), and 33 mm in Tripura (23% below normal). Nagaland is the only northeastern state that has recorded normal rainfall.

Sanjay O’Neil Shaw, Deputy Director General of Meteorology at Regional Meteorological Centre, Guwahati, stated that scattered rainfall to fairly widespread rainfall activity with thunderstorms and lighting are likely over the northeast while isolated heavy rainfall over Assam, Meghalaya, and Arunachal Pradesh has been predicted till Tuesday.

The IMD has predicted a drop in rainfall from Wednesday as the cyclonic circulation over East Bangladesh and its neighbourhood at 0.9 km above mean sea level has become less marked. At present, it’s the pre-monsoon period in Assam. The monsoon hits the state usually in April-May and continues till October.

This year’s rainfall pattern in Assam is an interesting contrast to the previous year. According to data, Assam recorded comparatively less rainfall in 2021 while it has received excess rainfall last year. It is worth noting that the excess rainfall in the region also causes flooding and landslides, which can cause damage to property and loss of life.

The northeast region of India is prone to natural calamities like landslides, flash floods, and heavy rainfall during the monsoon season. Therefore, it is important to closely monitor the rainfall patterns in the region and take necessary precautions to minimize any damage that might occur.

The IMD’s prediction of a drop in rainfall after Wednesday should be taken seriously and preparations should be made to mitigate any potential harm that may come as a result of the changing weather patterns.
