GUWAHATI: The flood situation in Assam worsened on Thursday following incessant rains in the state and upper reaches of Brahmaputra river in neighbouring Arunachal Pradesh. The Central Water Commission (CWC) has issued an alert after the water level of Brahmaputra river crossed the warning level mark in Guwahati.

According to the CWC, the Brahmaputra river was flowing at least 0.20 metres above the warning level mark of 48.68 meter in Guwahati. The danger level mark here is 49.68 meter. The highest ever flood water level of Brahmaputra was 51.46 meter, which was recorded in 2004.

The monsoon hit the region on Saturday and already more than 60,000 population in 13 districts in the state have been hit by flood. This is the first wave of the annual flood this year. The state usually gets as many as four waves in a year.

According to the state government's assessment, altogether 64,934 people have been affected in Barpeta, Sonitpur, Dhemaji, Bongaigaon, Lakhimpur, Tinsukia, Darrang, Nalbari and Goalpara districts. Lakhimpur in northern Assam is the worst-hit district with over 25,000 people being affected.

After a delay of one day, the monsoon hit the northeast on Saturday. The meteorology department said the south-west monsoon was active over Arunachal Pradesh, Assam and Meghalaya on Monday. Weather officials said the conditions are favourable for more monsoon rain in the next few days.

According to weather forecast, heavy to very heavy rain is likely to occur at isolated places over Arunachal Pradesh on Tuesday and Wednesday and over Nagaland, Manipur, Mizoram and Tripura on Friday.
