Impacts and Suggested Actions for Cold Wave
Cold wave to severe cold wave conditions are very likely over West Madhya Pradesh on 12th to 13th November. An increased likelihood of various illnesses like flu, running or stuffy nose or nosebleed, which usually set in or get aggravated due to prolonged exposure to cold. Do not ignore shivering. It is the first sign that the body is losing heat. Get indoors. Frostbite can occur due to prolonged exposure to cold. The skin turns pale, hard and numb and eventually black blisters appear on exposed body parts such as fingers, toes, nose and or earlobes. Severe frostbite needs immediate medical attention and treatment. Impact on agriculture, crop, livestock, water supply, transport and power sector at some places.
Wear several layers of loose fitting, light weight; warm woollen clothing. Cover your head, neck, hands and toes adequately as majority of heat loss occurs through these body parts. Wear several layers of loose fitting, light weight; warm woolen clothing rather than one layer of heavy cloth. Eat vitamin-C rich fruits and vegetable and drink sufficient fluids preferably warm fluids to maintain adequate immunity. Avoid or limit outdoor activities. Keep dry, if wet, change cloths immediately to prevent loss of body heat. Wear insulated or waterproof shoes. Warm the affected area of the body slowly with lukewarm water; do not rub the skin vigorously. If the affected skin area turns black, immediately consult a doctor. Maintain ventilation while using heaters to avoid inhaling toxic fumes. Take safety measures while using electrical and gas heating devices. Extreme care needed for vulnerable people. Seek medical attention as soon as possible for someone suffering from frostbite or hypothermia. Protect livestock from cold weather.
Agromet Advisories for Heavy Rainfall
In Tamil Nadu, harvest matured rice and groundnut crops only during clear weather and store the harvested produce in safer places. Make arrangements to drain out excess water from fields of rice, sugarcane, cotton, black gram, maize and vegetables and plantations of coconut, banana and black pepper to avoid water stagnation. Provide support to banana plants with wooden poles to prevent them from falling.
In East Rajasthan, Madhya Pradesh and Chhattisgarh, apply light and frequent irrigation to the standing crops in the evening to protect the crops from low temperature stress or cold injuries. Use mulching and cover vegetable nurseries and young fruit plants with straw or polythene sheets to maintain optimum soil temperature.
Advisories for Livestock and Fishery
Keep the animals inside the shed during heavy rainfall and provide them balanced feed. Store feed and fodder in a safe place to prevent spoilage. Construct an outlet with proper netting around the ponds to drain out excess water, thereby preventing fish from escaping in case of overflow. Keep cattle inside the sheds during night and provide dry bedding to protect them from cold.
Advisories for Thunderstorm and Gusty Winds
Provide mechanical support to horticultural crops and staking or support to vegetables and young fruit plants or fruit-bearing plants to avoid lodging due to strong winds.
