Heavy rains will lash parts of northeast and southern peninsular India over the next five days, the India Meteorological Department (IMD) has said.
Even though monsoon currents are presently weak associated with the ongoing monsoon-break-like situation, the rains will continue over Andhra Pradesh, Telangana, Rayalaseema, north interior Karnataka, Tamil Nadu and Kerala till Friday. In monsoon-break phase, the rains largely remain restricted to northeast and southern peninsular India regions.
On Monday, some areas of Kerala, Karnataka, Tamil Nadu, Uttarakhand and Bihar reported very heavy to extremely heavy (115 mm to over 200 mm in 24 hours) rains. Some of the wettest areas were Bhagamandala, Karnataka – 210mm, Rasipuram, Tamil Nadu – 200mm, Koraput, Odisha – 170mm, Mussoorie, Uttarakhand – 160mm, Jalpaiguri, West Bengal – 151mm, Konni and Ranni, Kerala – 110mm.
For the past two weeks, these two regions had remained largely dry with weekly rain remaining deficient by minus 33 per cent and minus 29 per cent over southern peninsula and east/northeast India, respectively. Manipur and Tripura have not recorded normal rain so far in this season whereas Kerala’s rainfall came under ‘normal’ category only last week for the first time in this season.
