Despite rain in some parts of the state,Mumbai remained mostly dry on Thursday and rain deficit escalated to record 55 per cent for the island city and 27 per cent for suburbs from June 1 to date.
Between 8.30 am and 5.30 pm on Thursday,the suburbs recorded only 0.9 mm of rainfall while the island city recorded 1.8 mm. Other parts of the state such as Maharashtra and Marathwada received good rainfall due to favourable position of the monsoon trough and a good cloud patch over the area.
The Met department attributed this to the absence of no significant weather system to give rain to the city. At present,activity over Konkan is moderate as the offshore trough is feeble. The upper air cyclonic circulation which lies over northwest Bay of Bengal,and which we expected to become a surface-level system,has not happened as expected as it has formed mostly over land rather than the sea, said V K Rajeev,director,weather forecast,India Meteorological Department (IMD).
However,the upper air cyclonic circulation still prevails over the Bay area and we are waiting to see if it will develop into a low pressure area,which if happens,will activate the monsoon across the entire country, he said.
Meanwhile,maximum temperatures in the city dropped on Thursday due to cloudy skies for most of the day,with Colaba recording 29.20,down from 30.80 the previous day while Santacruz recorded 30.30,marginally below the previous days 30.500 Relativehumidity levels at 5.30 pm were 92 per cent and 81 per cent for Colaba and Santacruz respectively.
Occasional spells of rain or showers would occur in parts of the city and suburbs on Friday,the IMD website read.
