Tropical Cyclone Madi developed over the Bay of Bengal, northeast of Sri Lanka and east of India, last week.
After producing locally heavy rainfall across Sri Lanka and the southeast coastline of India for several days, the cyclone drifted northward last weekend over the open Bay of Bengal.
Parts of eastern Sri Lanka received 150-300 mm (6-12 inches) of rainfall last week; however, this round of heavy rainfall will impact southeast India.
