Vegetable prices rise
Consistent rains have also increased woes of consumers in the city as vegetable prices continue to escalate. One kg of tomatoes were priced as high as ₹130 in Koyambedu wholesale market on Monday.
Officials noted such thunderstorms are possible during northeast monsoon. They occur during early morning hours like on Monday, when warm air from the sea interacts with cool land breeze. Sea surface temperatures are generally higher now.
Such rainfall may gradually decrease during the day. While rains may largely ease out over northern parts of the State till Wednesday, rain bands may shift to south Tamil Nadu and delta districts and may be heavy in one or two places.
