IMD issues heavy rainfall alert for Andhra Pradesh until October 21

The India Meteorological Department has issued rainfall alerts across southern and coastal districts of Andhra Pradesh, predicting an extended wet spell through October 21. Disaster response teams and local administrations across the affected regions have initiated monitoring measures to handle localized waterlogging and ensure public safety.

An orange alert, signifying a call for heightened administrative readiness, remains active for Chittoor, Tirupati, and SPSR Nellore districts, where heavy to very heavy rainfall is expected. Yellow alerts cover extensive parts of Rayalaseema and central Andhra Pradesh, including YSR Kadapa, Anantapur, Kurnool, Nandyal, Sri Sathya Sai, Annamayya, NTR, Krishna, West Godavari, Guntur, Palnadu, Prakasam, Bapatla, and Dr. B.R. Ambedkar Konaseema.

What caused the wet spell in Andhra Pradesh

According to meteorologists at the agency, the downpours are driven by an upper air cyclonic circulation hovering over North Tamil Nadu and adjoining South Coastal Andhra Pradesh. A weather trough also extends from the upper air cyclonic system over northern Lakshadweep across Kerala and Tamil Nadu to the Southwest Bay of Bengal.

State emergency services and district authorities are maintaining continuous surveillance over vulnerable low-lying areas. The proactive issuance of early warnings has enabled regional public works and civic bodies to clear drainage paths and safeguard essential infrastructure.
