South Peninsular India is likely to observe dry weather conditions during the next 10days, across the region. Sub divisions of Rayalaseema & South Interior Karnataka and states of Tamil Nadu and Kerala will run through a dry spell over the next about 2 weeks.
Earlier, during last week of January, a freak depression over Sri Lanka, Gulf of Mannar and Comorin Sea resulted scattered rainfall over South Peninsula. Now, existing cyclonic circulation located south of Sri Lanka, in the equatorial region is rather far to influence weather conditions over extreme southern parts. This circulation also will clear the area in the next 48hr and there is no fresh perturbation likely for the subsequent one week.
January and February, as such, are the least rainiest months for South Peninsula. Rains start catching up from March onward, more so for Tamil Nadu and Kerala. Northward shift of ITCZ favours increased thunderstorm activity around March Equinox.
Dry weather conditions are likely over South Peninsula for the next 2 weeks or even longer. Day temperatures will rise to mid 30's and crossing 36 deg over interiors of Rayalaseema and Tamil Nadu. Kurnool, Anantapur, Tirupati, Chittoor, Nandyal, Salem, Coimbatore, Erode and Tirupur will often exceed 36 degree in the coming days.
Since the winds over South Peninsula are predominantly northeasterlies, streaming from the Bay of Bengal, parts of Kerala also will witness temperatures in excess of 35 degree at some places. Kozhikode, Cochin, Kottayam, Pattambi and Vellanikkara will also exceed the threshold of 35 degrees frequently. Hot and humid conditions over deep inland and oppressive sultry conditions are expected along the coast, more so, on the western side of South Peninsula.
