GUWAHATI, July 30 - The depression, or the low atmospheric pressure of higher order, which was yesterday lying stationary over the northeast Bay of Bengal and its adjacent coastal areas of Bangladesh and West Bengal, today turned into a deep depression. Like the depression yesterday, it is also preventing incursion of moisture to the Northeast India, leading to a virtual rainless condition, mainly in Assam and Arunachal Pradesh. This has made the day (maximum) temperatures shoot up in many areas of the region.
Intensity wise, a deep depression is a precursor of a cyclone.
Sources in the Borjhar-based Regional Meteorology Centre (RMC) here said that the prevailing weather situation in NE India may undergo a change with this system crossing Bangladesh coast and making a west northwestward move in the forenoon of tomorrow.
Under the impact of this system, Guwahati today recorded the highest July day temperature of 37.6° Celsius in a period of around 50 years since 1966. During the period, the temperature of 37.5° Celsius recorded in the city on July 13, 2009 was the highest July day temperature for it till yesterday. Itanagar also recorded a day temperature of 37.6° Celsius today.
Under the impact of the above system, Dibrugarh today recorded a day temperature of 37° Celsius, Jorhat and Tezpur recorded 36° Celsius, North Lakhimpur 36.4° Celsius, Silchar 34.7° Celsius, Dhubri 34.4° Celsius, Aizwal 27.9° Celsius, Kohima 30.8° Celsius, Imphal 29° Celsius, Shillong 26.8° Celsius and Agartala 34.8° Celsius, said the RMC sources.
