Relief measures are in full swing as rain has subsided in most parts of Tamil Nadu. However, the Met office has forecast isolated heavy rain in south coastal Tamil Nadu including Kannya Kumari, Thoothukudi and Tirunelveli during the next 24 hours because of upper air circulation over Kumari Sea. A special Passport mela will be held today exclusively for rain-flood affected persons at the three Passport Seva Kendras of Chennai Regional Passport office. Passport fee of 3,000 rupees will be waived for those who lost their passport in the rain according to Chennai Regional Passport Officer K Balamurugan.
