Guwahati: From Moreh in Manipur to Kokrajhar in Assam, heavy rain lashed the northeast in the last 24 hours. The IMD issued a red alert for several NE districts again for Friday, especially in the lower Assam region, as southwest monsoon has further advanced into remaining parts of the northeastern states."Heavy (7-11 cm in 24 hours) to very heavy rain (12-20 cm in 24 hours) is very likely to occur at a few places with isolated extremely heavy rainfall (21 cm and more in 24 hours) over the districts of Dhubri, South Salmara, Goalpara, Baksa, Bajali, Bongaigaon, West Karbi Anglong, Dima Hasao, Cachar, Hailakandi and Sribhumi districts, accompanied by squally wind at a speed of 40-50 kmph gusting up to 60 kmph," the Regional Meteorological Centre (RMC) of the IMD stated in its special weather bulletin for Friday.Though rain submerged various parts of Guwahati, the rainfall amount was only moderate, exposing the lack of a proper drainage system, officials said.
