GUWAHATI, May 4 � The overall surplus in the State�s pre-monsoon rainfall has now come down to 57 per cent from the 88 per cent a few days back. Since March 1 last to May 3, the State has received a total rainfall of 467.3mm, against the normal of 296.9mm, said sources in the Regional Meteorology Centre (RMC) here today.
Meanwhile, sources said, a trough of low pressure is found running from East Uttar Pradesh (UP) and North West Bay of Bengal. This is accompanied by a trough in the lower level spreading itself between East UP and NE Assam across the sub-Himalayan West Bengal. It is extending up to .9 km above the sea level. These two troughs are embedded with cyclonic circulations one over East UP and the other over NE Assam.
Under the influence of these two troughs, rain or thundershower may occur at a few places over the NE region during the next 24 hours. There is also the possibility of a partly cloudy sky over the city and its neighbourhood during the period. Rain or thundershower may also occur in the city and its adjacent areas during the same period. Maximum temperature in the city is expected to be around 33 degree Celsius on Wednesday, said the sources.
