Mumbai Unlikely To Have Heavy Rainfall For One Week, Brief Spells Of Light-Moderate Showers To Continue

Typical heavy Mumbai rains have gone missing for the last one week. In fact, the base observatory at Santacruz has not recorded any three-digit 24-hour rainfall in this month so far. However, Colaba has seen such rainfall on two occasions and has received much more rain than Santacruz. Mumbai has a normal of 493.1 mm rainfall for June, and Santacruz has recorded 478.7 mm between 1st and 26th June. An additional 16 mm rainfall was recorded between 8:30 AM and 11:30 AM today. With this, both observatories—Santacruz and Colaba—have surpassed the average rainfall for this month. Scattered light to moderate showers in the remaining days will be a bonus for the opening month of the monsoon.

Mumbai receives heavy rainfall under familiar meteorological conditions. A north-south trough off the Western Ghats, over the sea, becomes a semi-permanent feature during the monsoon season and keeps triggering frequent showers. Strong systems forming over the Bay of Bengal strengthen the westerly stream along the Konkan region, accentuating monsoon bursts. Also, the remnants of these systems, in the form of cyclonic circulations, cause heavy to very heavy rainfall when positioned over West Madhya Pradesh, North Gujarat, and South Rajasthan.

At present, none of these systems are active, and similar conditions are likely to persist for the next one week or so. With this, vigorous monsoon conditions are unlikely for Mumbai and its suburbs during the remaining days of the month and into early next week. Light to moderate showers with short bursts of one to two hours will remain the highlights over the next week. A monsoon system is expected to form over the Bay of Bengal soon. The remnant of this system, as a cyclonic circulation, is likely to reach South Rajasthan and West Madhya Pradesh around 3rd–4th July. The intensity and duration of showers are expected to pick up during that time.

The upcoming month of July is the rainiest month, with a massive average of 840.7 mm rainfall. July and August together form the most active phase of the monsoon for the city. Most disruptions to communication and connectivity, hardships for the common man, and disorder in rail, road, and air operations become synonymous with this vibrant city during this period. Exercise caution and be prepared with the utmost readiness to meet any exigency.
