With the southwest monsoon gaining momentum over the southern peninsular region, the Regional Meteorological Centre has declared a red alert for Nilgiris district, indicating the possibility of extremely heavy rainfall in isolated places on Saturday and Sunday.
The prevailing upper air circulation over the southern peninsular region and the strong monsoon current would trigger heavy rainfall over Western Ghats districts and a few adjoining districts, said RMC officials.
The Meteorological Department has warned about the extreme weather-related impact over the Western Ghats areas such as waterlogging, road blockages and landslides or mudslides that are likely in hilly areas.
In its bulletin, the RMC has predicted scattered rainfall over Tamil Nadu and Puducherry till June 18. One or two places in Nilgiris district may receive extremely heavy rainfall above 20 cm on Saturday and Sunday. On Saturday, the ghat areas of Coimbatore and Tirunelveli district and Tenkasi and Kanniyakumari are likely to get rainfall up to very heavy intensity. Theni and Dindigul districts have been issued with yellow alert, indicating heavy rainfall.
While the similar pattern of heavy rain may continue on Sunday, some more districts like Tiruppur, Dindigul, Madurai and Virudhunagar are likely to get heavy rainfall. Heavy downpour is likely to batter Western Ghats districts, including Coimbatore, Nilgiris, Theni and Tenkasi until June 18.
