[caption id=“attachment_11752131” align=“alignnone” width=“671”] North east monsoon - seasonal rains in meteorological subdivisions of the country till 3rd December[/caption] Current synoptic features influencing weather in India as on 4 December: • The western disturbance as a trough in middle and upper tropospheric westerlies with its axis at 5.8 km above mean sea level roughly along longitude 67°E to the North of latitude 25°N persists. • A cyclonic circulation lies over South Andaman Sea & adjoining equatorial Indian ocean-Strait of Malacca and extends up to 5.8 Km above mean sea level. Under its influence, a low pressure area is likely to form over South East Bay of Bengal & adjoining South Andaman Sea by 5 December. It is likely to move West- North Westwards and concentrate into a depression over South East Bay of Bengal by 7 December morning. Thereafter, it is likely to continue to move West- North Westwards and reach South West Bay of Bengal near north Tamil Nadu-Puducherry & adjoining South Andhra Pradesh coasts by 8 December morning. All-India weather forecast till 10 December: The dull week in terms of weather activities in India is about to end as we head next week, upcoming days are all set be interesting with fog and typical winter feel setting in the northern parts of the country while there is high probability of a cyclone developing in bay of Bengal and impact states in South India with heavy rains and strong winds will be a sudden turn of the events within a week. South India: The weather conditions will be mainly dry in Andhra Pradesh, Telangana, Karnataka, Goa for the next 3-4 days, till Wednesday parts of Tamil Nadu and Kerala will observe subdued rainfall activities. Weather models are in fairly tight agreement in formation of the low pressure area over South East bay of Bengal by Monday evening while moving North Westwards it is very likely to concentrate into Depression over South East bay of Bengal by the morning of 7 December. Additionally the presence of Kelvin wave and the potential arrival of MJO in a couple of days time over Indian Ocean is another factor that could not be ignored while trying to summarize the life cycle of the upcoming disturbance. The passage of MJO over Indian Ocean increases the probability of the upcoming disturbance intensifying into a marginal cyclone though question marks will remain on the intensity at the time of landfall. Whether the system makes landfall as cyclone or a deep depression, most parts of Tamil Nadu, South Andhra Pradesh to experience very heavy to extremely heavy rains in the period of 8 to 10 December, specifically coastal areas to experience strong winds, storm surge and high risk of flooding. As the system moves inland moderate to heavy rains are expected over Bangalore, parts of Karnataka and Kerala during 9 to 11 December.

North India: The slow transition towards winter is picking up pace with dense fog seen in parts of Punjab, Haryana and Uttar Pradesh on 4 December, despite the absence of western disturbance there is abundant moisture present in the plains of North India, also slow wind speed during the nights can favor the expansion of dense fog across Punjab, Haryana, Delhi NCR, Uttar Pradesh and North Rajasthan during the upcoming week, even if the fog stays till morning hours it will result in saturated atmospheric conditions, eventually the day temperatures will start decreasing to the normal levels in the next week, most stations to start recording maximum temperature in the range of 20 to 25°c in the period of 5 to 10 December.
