Another wet day, Mumbai rain to soon breach 1,000mm mark – Times of India

MUMBAI: As heavy spells of rain continued to lash most parts of Mumbai, Thane and Navi Mumbai till Wednesday evening, the season’s total rainfall inched closer to the 1,000mm-mark.
Since June 1, the total rainfall recorded in Mumbai was 958mm, which is 43% of the season’s total required rainfall of 2,205mm.

The IMD Santacruz observatory again recorded triple-digit rainfall-194mm-in the 24-hour period ending 8.30am Wednesday. The IMD Colaba observatory recorded 84mm of rainfall during the same period. By afternoon, the wet spell started tapering off as Santacruz and Colaba received 31.8mm and 24.8mm of rainfall in the 12-hour period ending 8.30pm.
Since June 1 till Wednesday 5.30pm, the total rainfall recorded by the IMD Colaba observatory is 867.4mm and the Santacruz centre, 958 mm
In its five-day forecast for Mumbai and Thane, the India Meteorological Department (IMD) retained its orange alert. Weathermen said heavy to very heavy rainfall is very likely at a few places with extremely heavy rain at isolated places on Thursday and Friday. From Saturday, the intensity of rain is expected to reduce with indications for heavy to very heavy rain at a few places.
IMD officials said the current weather conditions that are giving the Mumbai Metropolitan Region (MMR) such intense spells of rain include a low pressure area which lies over Kutch and neighborhood with the associated cyclonic circulation. “An off-shore trough at mean sea level runs from Gujarat coast to Karnataka coast. Also an east-west shear zone runs roughly above mean sea level tilting southwards with height across North Peninsular India. Another condition is a cyclonic circulation lies over north Odisha and adjoining Chhattisgarh and extends upto 1.5km above mean sea level,” said an IMD official.
Meanwhile, the Doppler radar at Colaba has continued to remain suspended despite the heavy rain spell. This is the second time that the Doppler has been suspended this season. Earlier, it was during mid-June when an orange alert for heavy to very heavy rainfall was issued.
The S-band Doppler weather radar, which can track weather up to 500km radius, is situated atop a building in Colaba’s Navy Nagar area. Doppler radar made an entry into the weather bureau following the July 26, 2005 deluge when Mumbai received 944mm of unannounced rainfall. Inaugurated in January, the radar at Veravali, which is C-band, is located on land provided by the BMC.
