Tamil Nadu Weather: Low Pressure Area Brings Rain

Tamil Nadu Weather Update: Low Pressure Area Forms, Rain Expected for a Week

The India Meteorological Department (IMD) has forecasted the formation of a low pressure area over the northwest Bay of Bengal on August 25, 2025. This weather system is set to bring light to moderate rainfall across Tamil Nadu and Puducherry for the next seven days, offering respite from the ongoing heat. Alongside this, the IMD has issued critical warnings for coastal regions, advising fishermen to avoid sea ventures due to cyclonic storms in the Arabian Sea and parts of the Bay of Bengal.

Rainfall Forecast for Tamil Nadu and Puducherry

The Meteorological Department predicts light to moderate showers across Tamil Nadu and Puducherry for the coming week, driven by the low pressure area in the Bay of Bengal. While rainfall will likely be scattered, certain areas may experience more consistent showers. The IMD notes that maximum temperatures in parts of Tamil Nadu could rise 2 to 3°C above normal, potentially reaching 36°C. Residents are advised to stay hydrated and take precautions during outdoor activities to cope with the heat.

Chennai Weather Forecast

In Chennai and its surrounding suburbs, partly cloudy skies are expected, with chances of light rain in some areas. The maximum temperature in the city is projected to hover around 36°C, with minimum temperatures ranging between 27°C and 28°C. High humidity combined with above-normal temperatures may make conditions feel warmer, prompting the IMD to recommend caution during peak afternoon hours.

Cyclonic Storms Along Coastal Regions

The IMD has reported cyclonic storms in multiple coastal areas. In the West Central and Southwest Arabian Sea, as well as the East Central and Northeast Arabian Sea, wind speeds are expected to reach 45 to 55 kmph, with gusts up to 65 kmph. The Gujarat and North Konkan coasts will likely experience cyclonic storms with wind speeds of 40 to 50 kmph and gusts up to 60 kmph. These conditions pose significant risks to maritime activities, leading to warnings for fishermen and coastal communities.

Fishermen Urged to Avoid Sea Ventures

The Meteorological Department has issued a specific advisory for fishermen along the South Tamil Nadu coast, the Gulf of Mannar, and the Kumarikadal areas, urging them to refrain from venturing into the sea today. Strong winds and cyclonic activity are expected to create rough sea conditions, posing dangers to small vessels and fishing operations. Fishermen are encouraged to adhere to the IMD’s advisories and stay updated on weather developments.

Preparing for Changing Weather Conditions

As Tamil Nadu prepares for a week of rainfall, residents are urged to stay informed through regular updates from the IMD. The combination of rain, elevated temperatures, and potential cyclonic activity necessitates vigilance, particularly in coastal and low-lying areas. Local authorities are actively monitoring the situation to ensure public safety and readiness for any disruptions caused by heavy rainfall.
