After five days of heavy rain, the city recorded negligible rainfall on Friday morning. Weathermen said some of the factors responsible for heavy rain along the Konkan coast, including Mumbai, had died down, but the possibility of heavy rain over the weekend cannot be ruled out.

“There is a well-marked low pressure area over coastal Andhra Pradesh and surrounding areas that is drawing moisture along the Konkan areas and interior Maharashtra. Mumbai could expect heavy to very heavy rain over the next 48 hours from Friday,” said Shubhangi Bhute, director, Regional Meteorological Centre, India Meteorological Department (IMD).

Bhute said an upper air cyclonic circulation over Saurashtra and Gujarat, which was one of the main factors for heavy rain over Mumbai, has died down. “Currently, there is change in the direction of wind, but the westerlies will be strengthened over the next 24 hours, which will help deposit moisture along the coast,” she said.

Between 8.30am on Thursday and 8.30am on Friday, the weather station at Santacruz recorded 39.7mm, while Colaba recorded 45.2mm of rain. Under the IMD’s new classification, 15.6mm to 64.4mm of rain is considered ‘moderate’, 64.5mm to 115.5mm is ‘heavy’, 115.6mm to 204.4mm is ‘very heavy’ and more than 204.5mm is ‘extreme’.

Between Tuesday and Wednesday, Santacruz recorded 142.6mm rain, while Colaba recorded only 37.4mm. The highest 24-hour rainfall figure for September in the past 10 years was recorded on September 4, 2012 (185.2mm). The all-time high record was on September 23, 1981 (318.2mm).

Meanwhile, the state disaster management authority’s weather bulletin predicted intermittent showers with a few heavy spells. “Spells of heavy to very heavy rain are likely in Raigad , Ratnagiri districts and south-central Maharashtra districts. Fairly wide spread rainfall is expected across the whole state with a few heavy spells at isolated places during the next 72 hours from Friday morning,” said RV Sharma, consultant (natural disaster), state disaster management unit.

Meanwhile, overnight temperatures were below normal levels on Friday combined with high moisture levels. Colaba and Santacruz recorded 98% and 95% humidity.
