Mumbai, Feb. 16 -- Signalling a gradual seasonal transition, Mumbai on Sunday recorded the highest temperatures in Maharashtra, with both day and night readings above normal levels. At Santacruz, the base observatory of the India Meteorological Department (IMD) in the city, the maximum temperature touched 35.2degC, 3.6 degrees above normal and the highest in the state. Colaba recorded a maximum of 33degC, 2.8 degrees above normal. Unlike the recent spell of cool and pleasant mornings, temperatures across south Mumbai and the suburbs remained above 20degC on Sunday. The minimum temperature at Santacruz was 21degC, while Colaba recorded 22degC. IMD officials attributed the warmer conditions to prevailing synoptic features. "Dry easterly winds over the region are delaying the onset of the sea breeze and lowering humidity levels. Additionally, an anti-cyclonic circulation is present near Mumbai and adjoining areas," said a senior scientist at the Regional Meteorological Centre, Mumbai. "This marks a gradual transition period." The current weather pattern is expected to persist for the next day or two, after which temperatures may dip slightly. The IMD has forecast a minimum of 22degC and a maximum of 35degC for Monday. Meanwhile, Mumbai's overall Air Quality Index (AQI) stood at 134. PM10 remained the primary pollutant at 23 of the city's 28 monitoring stations....
