Monsoon Tightens Grip Across India: Mumbai Waterlogged, Delhi Storm Brings Relief, Kolkata and Kerala Face Severe Weather Disruptions
India’s monsoon intensifies across major cities with Mumbai facing waterlogging and transport disruptions under an orange alert, Delhi witnessing a dust storm and sharp temperature drop, Kolkata reporting storm damage, Bengaluru receiving steady rain, and Kerala preparing for heavier rainfall with expanding alerts across districts.
Mumbai continues to bear the brunt of intense monsoon showers as the India Meteorological Department has downgraded its warning from a brief red alert to an orange alert for Mumbai, Thane, and Raigad. The city is forecast to experience moderate to heavy rainfall accompanied by lightning and thunderstorms. The IMD’s 0800 hours bulletin confirms generally cloudy skies with continued rainfall activity across Mumbai and its suburbs. Severe waterlogging has disrupted civic life, with several Brihanmumbai Electric Supply and Transport bus routes diverted and commuters advised to check routes before travel. The Trans Harbour Rail Link remains suspended, while at least one underpass has been shut due to flooding conditions.
Delhi witnessed a dramatic shift in weather conditions as a powerful dust storm ended the prolonged heatwave. Wind speeds exceeding 50 kilometers per hour swept across the capital, followed by rainfall that brought immediate relief. Temperatures at Safdarjung dropped sharply from approximately 40 degrees Celsius to 33 degrees Celsius, while Ayanagar recorded a steep fall from 40.6 degrees Celsius to 25.7 degrees Celsius. Although a red alert was briefly issued during peak storm activity, forecasts indicate intermittent thunderstorms and light rain throughout the week as monsoon influence strengthens. Maximum temperatures are expected to stabilize between 38 and 40 degrees Celsius.
Kolkata and several parts of South Bengal have been placed under an orange alert as heavy rain accompanied by wind speeds reaching up to 60 kilometers per hour caused widespread disruption. The storm uprooted trees and led to significant traffic congestion, particularly at Dharmatala where a fallen tree blocked Central Avenue. Affected districts include North 24 Parganas, South 24 Parganas, Howrah, Hooghly, East Midnapore, and West Midnapore. Authorities have warned that lightning poses a risk of damage to kutcha houses and standing crops, urging residents to remain indoors unless absolutely necessary.
Bengaluru experienced relatively stable monsoon conditions with steady moderate rainfall and no major disruptions reported. Temperatures hovered between 22 and 23 degrees Celsius with humidity at 81 percent. Forecasts for Wednesday indicate patchy rain in surrounding regions, with humidity easing to around 71 percent and temperatures remaining stable near 23 degrees Celsius. Heavier rainfall is expected to return from July 1 as monsoon activity strengthens across Karnataka.
Kerala’s monsoon continues to intensify progressively from northern districts southward. The India Meteorological Department has issued a yellow alert for Kozhikode, Wayanad, Kannur, and Kasaragod, forecasting heavy rainfall ranging between 64.5 millimeters and 115.5 millimeters within a 24-hour period. By Saturday, the alert is expected to expand to eight districts, including Malappuram, Ernakulam, Thrissur, and Palakkad. Thodupuzha in Idukki recorded 13 centimeters of rainfall within the 24-hour period ending Tuesday morning, underscoring the strengthening monsoon system across the state.
Across India, the intensifying monsoon has created a complex weather landscape marked by urban disruption, temperature volatility, and escalating rainfall alerts, reflecting the full onset of seasonal monsoon activity.
