IMD warns of heavy rains in State

By Ajit Patowary

GUWAHATI, May 18 - Rain or thundershower may occur at most of the places over Assam and Meghalaya during the next 48 hours, since 8.30 am today, under the impact of a cyclonic circulation, which is lying over East Uttar Pradesh and adjoining Bihar and its neighbourhood, extending up to 0.9 km above the mean sea level.

Disclosing this, sources in the Borjhar-based Regional Meteorological Centre (RMC) of the India Meteorology Department (IMD) here said this afternoon that heavy to very heavy rain is very likely to occur at isolated places over Assam-Meghalaya Meteorological Subdivision on May 18 and 19 and over the Nagaland-Manipur-Mizoram-Tripura Meteorological Subdivision on May 21 and 22.

Heavy rain is very likely to occur at isolated places over the Assam-Meghalaya Meteorological Subdivision on May 20 and at isolated places over Arunachal Pradesh on May 18 and 19.

However, intensity and frequency of the rainfall activities over the Assam-Meghalaya Meteorological Subdivision and the Arunachal Pradesh Meteorological Subdivision are expected to decrease after 48 hours, sources said.

Warning: Meanwhile, the Assam State Disaster Management Authority (ASDMA) said, quoting today�s RMC weather warning, that heavy to very heavy rain is likely to occur at isolated places over Tawang, East Kameng, West Kameng, Kurung Kumey, Papum Pare, Lower Subansiri, Anjaw, Lower and Upper Dibang districts of Arunachal Pradesh on May 18 and 19.

This may affect Udalguri, Sonitpur, Biswanath, Lakhimpur, Dhemaji and Tinsukia districts of Assam, said the ASDMA in a press communique.

Significantly, during the past 24 hours ending at 8.30 am today, Cherrapunji in Meghalaya received 245 mm of rainfall.

Guwahati received a total amount of 15.8 mm of rainfall during the above period. Haflong received a total amount of 80.4 mm of rainfall, Rangiya received a total amount of 85 mm of rainfall, Kokrajhar received a total amount of 78 mm of rainfall and Gossaigaon received a total amount of 93.2 mm of rainfall during the same period, said the RMC sources.

The amounts of rainfall received by the above places in a pre-Monsoon day, barring Guwahati, seemed to be much above their respective normal amounts of rainfall for the pre-Monsoon period. However, considering the factor of the rainfall activities being associated with deep convection, such high amounts of rainfall in a single day during the pre-Monsoon period cannot be ruled out, said Sunit Das, Scientist-D of the RMC.
