# Cyclone Arnab rain in Mumbai short-lived, no showers from Saturday 2026-10-31T03:27:06+00:00 | India | Indian Opinion Desk Corroboration: 1 independent outlet Mumbai woke up to light drizzle in parts of the city on Friday, 30 October, bringing relief from heat and pollution. The unseasonal showers, driven by Cyclone Arnab, also improved the air quality index (AQI) to a satisfactory level of 77, with 19 of the city's 21 active stations recording AQI under 100. Pockets like Colaba and Worli saw AQI dip below 50 during the morning. The India Meteorological Department (IMD) has forecast 'mainly clear skies' in Mumbai and the neighbouring districts of Thane, Palghar, Raigad and Ratnagiri from Saturday, 31 October, with no showers predicted. Maximum temperatures are expected to stay at 33 degrees until Saturday. The rain activity is expected to be short-lived. Brihanmumbai Municipal Corporation (BMC) automatic weather stations recorded 9 mm of rain in Lower Parel, 4 mm in Sewri, 5 mm in Chembur and 3 mm in Govandi between 9 am and 10 am on Friday. The western suburbs saw no rainfall. Cyclone Arnab developed into a depression by 24 October and made landfall over the Andhra Pradesh coast on 28 October. ## Indian Opinion Analysis The relief from Mumbai's heat and pollution will be brief. IMD's forecast of mainly clear skies from Saturday, 31 October, means the city returns to the moderate AQI levels seen in recent days, while temperatures stay at 33 degrees. The showers were a by-product of Cyclone Arnab's cloud cover spreading over western stations, not a sustained weather system, so no further rain is expected. The short duration of the improvement leaves the city exposed to rising heat and deteriorating air quality once the cloud cover clears, and the next measurable change will be temperature and AQI readings after the weekend. ## Coverage - indianexpress.com Straight weather report with IMD forecast and BMC rainfall data, no political slant.
