THE WATER

The Odisha chapter closes as a new low forms over the North Bay of Bengal and tracks west-north-west over about five days, steering the next active window, Sep 18–20. The prior inland low sits over south-east Rajasthan and north Gujarat: Saurashtra and Kutch step from isolated extremely-heavy on Sep 14 to isolated heavy today, with a low-to-moderate flash-flood risk in eight districts and fishermen advised off the Gujarat coast through Sep 16. A fresh Haryana, Punjab, Delhi and Uttarakhand spell is indicated, and withdrawal may begin around Sep 19.
