Udhagamandalam:
The temperature in and around this hill station, a major tourist spot, touched zero degree, with frost covering nearly a 10 kilometre area, officials said.
Tourists and citizens ventured out only after 8.30 am, as the biting cold made them sit indoors, they said.
A 'white carpet of frost' was seen over the plains, tea estates, including in and around the town, the famous botanical gardens and also Wenlock downs, they said.
