Current rainfall activities to continue

By Ajit Patowary

GUWAHATI, April 20 - By and large, pre-monsoon rainfall over the NE region so far this year is deficient, although the current rainfall activities over the region are likely to continue for the next 48 hours.

Sources at the Borjhar-based Regional Meteorology Centre (RMC) here said that a cyclonic circulation over the Sub-Himalayan West Bengal and adjoining West Assam, which is extending up to 1.5 km above the mean sea level (ASL) and an East-West trough at point 9 km above the mean sea level, which extends from east Uttar Pradesh to Manipur, across Bihar, are at the root of the present weather condition over the NE region.

These two developments have been observed since yesterday and rainfall activities over the NE region are expected to continue for the next 48 hours and decrease thereafter, RMC sources said.

Meanwhile, Assam recorded a total pre-monsoon rainfall of 138.7 mm since March 1 to April 18, against the normal of 169.7 mm. Likewise, Meghalaya recorded a total rainfall of 113.8mm during the period, against the normal of 171.4 mm.

During the period, Nagaland recorded a total rainfall of 79.5 mm, against the normal of 137.3 mm; Manipur recorded a total rainfall of 34.2 mm against the normal of 131.7 mm; Mizoram recorded a total rainfall of 27.8 mm against the normal of 159.9 mm; Tripura recorded a total rainfall of 79.3mm against the normal of 215.3mm and Arunachal Pradesh recorded a total rainfall of 224.7 mm against the normal of 341.1 mm, RMC sources said.
