Mumbai rained heavily over the last 5 days between 08th and 12th June. A total of 715.3mm rainfall has already been registered for Mumbai, an excess of 589.1mm against the normal of 126.1mm. Rainfall has exceeded the monthly normal of 493.1mm for Mumbai and is heading for a huge surplus in the remaining days of the month.
Rains over Mumbai have taken a breather and were generally light since yesterday evening. These are likely to be sparing even till tomorrow morning and pick up thereafter. Moderate rains with a few heavy spells are expected over Mumbai in the next 48 hours.
Low pressure over the Bay of Bengal has moved partly overland covering parts of Odisha and West Bengal. It is likely to move further over Jharkhand and Chhattisgarh. Consequentially the western arm of the monsoon over the Arabian Sea will pick up strength and throng the Konkan coast including Mumbai, once again. It has rained heavily over most parts of Konkan in the past 24 hours. Ratnagiri has received 150mm rainfall in 24 hours ending 8.30 am today.
Cyclonic circulation earlier persisting over the Arabian Sea off the Konkan coast has weakened. However, an east-west trough still is marked across Konkan, Vidarbha, Chhattisgarh, Odisha, and the center of low pressure. Low pressure is expected to become more marked and westerly streams along the west coast will pick up strength. Monsoon rains will accentuate again in general over Konkan and Mumbai in particular. South Konkan and Goa is heading for extremely heavy rains over the next 3-4 days. Mumbai, Thane, Alibag, and Palghar also will have intense rains over the next 2-3 days.
