GUWAHATI, July 28 - A depression, or a low atmospheric pressure area of higher order, that has remained stationary over the North East Bay of Bengal and its contiguous coastal areas of Bangladesh and West Bengal, has been blocking moisture incursion to the NE region since July 26, resulting in the rainless condition mainly in Assam and Arunachal Pradesh and catapulting a jump in the maximum (day) temperature in many areas of the region.
However, according to sources in the Borjhar-based Regional Meteorology Centre (RMC) here, the redeeming feature in this gloomy situation is that there is 50 per cent likelihood of rainfall and thunderstorm activities over the West Assam areas today.
A similar condition prevails over Guwahati too for the next 24 hours since this afternoon, while rainfall activities at a few places over Assam are expected today, tomorrow and day after tomorrow, sources said.
Under the influence of the system mentioned above, the city today recorded a maximum temperature of 37 degree Celsius. It recorded the same day temperature yesterday under the influence of the same system.
However, till date, the day temperature of 37.5 degree Celsius recorded by the city on July 13, 2009, has remained the highest maximum temperature recorded by it in the month of July, since 1966, said the RMC sources.
Though rainfall activities mainly in Arunachal Pradesh and Assam are thwarted by the above low pressure system, Mizoram and Tripura are experiencing rainfall activities these days due to moisture incursion through the southeasterly wind, said the RMC sources.
