NEW DELHI: Incessant rains in most parts of northwest India and parts of east India due to two existing ‘well marked’ low pressure areas has put many districts of Uttarakhand, Himachal Pradesh and Gangetic Bengal under flash flood risk within the next 12-24 hours. IMD Friday issued relevant warnings (Red and Orange alerts for ‘taking action’ and ‘be prepared’, respectively) to local authorities due to heavy rainfall in many parts of these states.
Though the low pressure area over northwest India, that triggered rains in western UP, Delhi, Haryana, Uttarakhand and Himachal Pradesh on Friday, is likely to be weaken on Saturday, the risk of “moderate to high flash flood” risk in certain districts and localised urban floodings in others is likely to be there throughout the day.
Met dept said the surface runoff or inundation may occur at some fully saturated soils and low-lying areas due to expected rainfall occurrence in the next 24 hours.
The situation will persist in east India, mainly Gangetic Bengal, Odisha & Jharkhand, a bit longer as IMD predicted that the well marked low pressure area over northeast Bay of Bengal is “likely to continue to move west-northwestwards and intensify into a ‘depression’ over coastal Bengal and adjoining northwest Bay of Bengal by September 14”.
As a result, while Odisha, Jharkhand and Bihar may experience very heavy to extremely heavy rainfall till Sept 15, certain districts of Bengal – South and North 24 Parganas, Purba Medinipur, Paschim Medinipur, Haora, Hugli, Nadia and Bankura – are expected to face “low to moderate flash flood” risk. IMDissued ‘Orange’ (be prepared) alert for Jharkhand & ‘Red’ (take action) alert for Odisha and Bengal for Saturday.
Localised flooding of roads, water logging in low lying areas and closure of underpasses mainly in urban areas, localised landslides/mudslides, and damage to horticulture and standing crops are some of the expected impacts, listed by IMD for Uttarakhand, Himachal, UP, Haryana, Gangetic Bengal, Odisha, Jharkhand, Bihar, and Chhattisgarh due to heavy rainfall.
