Southwest Monsoon ended August yesterday with a deficit of 23% and an overall deficit of 11% for the season. In recent years both July & August, the traditionally rainiest months, having overall deficits has been a not so regular phenomenon.
Southwest Monsoon Update: The Monsoon trough continues to be parked along the Himalayan foot hills with the rains confined to Northeast India and parts of East India thanks to the North South Trough between Bihar & Odisha. Crucially in what could have ramifications on the withdrawal of Southwest Monsoon the Upper level westerly Jetstreams have started to show a southerly dip,an indication of potential withdrawal process underway, over Northwest India. Places like Jaisalmer are pretty much showing no rain forecast for the next couple of weeks indicating a change on ground as well.
