Weather Based Agro Advisory

Significant Weather Features (IMD)

  • Dense to very dense fog observed at most places over East Uttar Pradesh; at a few places over West Uttar Pradesh, Bihar, Sub Himalayan West Bengal and at isolated places over Haryana, northwest Rajasthan, Assam & Meghalaya and Nagaland, Manipur, Mizoram & Tripura; Dense fog at isolated places over Saurashtra & Kutch. Moderate fog observed at isolated places over Delhi.
  • Yesterday, Severe cold day conditions observed at a few places over East Uttar Pradesh; Cold day conditions observed at a few places over Bihar and at isolated places over Gangetic West Bengal. Today, Cold wave conditions observed at isolated places over Jammu & Kashmir, East Madhya Pradesh, West Uttar Pradesh, Bihar, Odisha and Gangetic West Bengal.
  • The present western disturbance over north Pakistan is likely to move away northeastwards during next 24 hours. A fresh western disturbance interacting briefly with an easterly trough is likely to cause isolated to scattered rainfall over northern plains and rain/snow over western Himalayan region during 22nd24th. No significant change in night temperatures likely over major parts of India and thus isolated cold wave and ground frost conditions may continue over northern plain eastern India during next 3 days. Likely strengthening of wind and reduction in humidity could lead to abatement of dense fog northwest India temporarily. However dense fog and cold day may continue over East Uttar Pradesh and Bihar during next 5 days.
