Vanakkam! The satellite pictures this Saturday morning were a sight to behold! The 8.30 am pictures showed rain clouds from late-in-the-season North-East Monsoon activity hovering over and around Chennai city. They were distributed right from the North, from Gudur, Srikalahasthi, and Ponneri, to Mamallapuram in the South, with backup thunderstorms looking in from over the Bay of Bengal waters to the South-East.

Clouds were also seen approaching Tharangambadi, Karaikal, Nagapattinam and Vedaranyam and into the Palk Strait around Rameshwaram, with a lone streak of rain showers maintaining a track from Puttalam in North-West Sri Lanka past the Gulf of Mannar towards the North of Tuticorin. Kalugumalai, to the North-West of Kovilpatti also saw rain clouds descending.

In fact, the Gulf of Mannar, which separates India from Sri Lanka, was buzzing with cloudy and rainy weather with a thunderstorm lording it over the Wilpattu National Park in Sri Lanka with a tail extending into Rameshwaram and further heading back to the North-West of Sri Lanka.

The India Meteorological Department (IMD), New Delhi, said this morning that a low-pressure area has formed in the immediate neighbourhood to the West and North-West as a trough in the easterlies had settled into position over the South-East Arabian Sea and adjoining equatorial Indian Ocean.
