Deep Depression Over the Bay of Bengal Triggers Heavy Rain Across Eastern India

The India Meteorological Department (IMD) classifies a system over the Bay of Bengal as a deep depression with sustained winds of 55–65 km/h and gusts to 75 km/h. It is moving west-northwest at 3–12 km/h and is expected to cross the north-Andhra Pradesh–south-Odisha coastline near Kalingapatnam on September 23, moving inland through September 24. The IMD forecasts the depression will retain its intensity for 12 hours before weakening over the next 24 hours.

A deep depression (winds 52–61 km/h) falls short of the cyclonic storm threshold (62–88 km/h). Although some outlets have called the system “Cyclone Arnab,” the IMD confirms no cyclone name has been assigned; “Arnab” remains on the regional list for future cyclonic storms.
