GUWAHATI, April 20 - People of the NE region may not get a respite from the rainy weather condition at least for the next four days. It is expected that the present weather condition of the region may undergo a change only after April 24, said sources in the Borjhar-based Regional Meteorology Centre (RMC) here this afternoon.
According to the RMC sources, Assam has recorded 125 per cent of its normal rainfall, 25 per cent above its normal rainfall, during the current pre-Monsoon period.
Explaining the factors responsible for the present weather condition, sources said that a huge moisture incursion from the Bay of Bengal towards the NE region has taken place during the past several days due to the presence of an anti-cyclone system over the Bay. This system, together with a trough of low pressure area, which is presently extending from Bihar to Manipur covering Gangetic West Bengal and Assam and Meghalaya, is creating the condition for the present state of weather in the region.
During the next 24 hours, rainfall or thundershower activities are expected at most places over Assam and Meghalaya. Such a state of weather is expected at many places over Arunachal Pradesh and the Nagaland-Manipur-Mizoram-Tripura region during the same period, the sources said.
The RMC has warned that thundersquall, with wind speed exceeding 60 km per hour and accompanied by hail, is very likely to lash isolated places in Assam and Meghalaya and the Nagaland-Manipur-Mizoram-Tripura Meteorological Subdivisions on April 20 and 21.
It has also warned that heavy to very heavy rainfall activities are very likely to occur at isolated places over Arunachal Pradesh on April 21 and 22. Heavy to very heavy rainfall is very likely to occur also at a few places over Assam and Meghalaya on April 21 and at isolated places over this met subdivision on April 22 and 23.
