Agricultural Guidance for Farmers

In Konkan region, farmers should store harvested rice and finger millet in secure locations. Arrange proper drainage for fields growing rice, finger millet, groundnut, and turmeric to remove excess water.

For livestock, shelter animals during any heavy rain and ensure balanced feeding. Keep feed and fodder in dry, safe storage to avoid damage. Around fish ponds, build outlets with netting to control water levels and stop fish from escaping during overflow.

To protect against thunderstorms and strong winds, provide supports to horticultural crops. Stake vegetable plants and young fruit-bearing trees to prevent them from falling over in gusts.

These updates highlight the varied weather patterns affecting different parts of India. Residents in hilly and urban areas should remain alert for any intense activity, especially where colour-coded warnings indicate higher risk.
