An area of showers and thunderstorms currently moving across the Bay of Bengal is becoming better organized and may become a named tropical cyclone in the next 24 hours.
These showers and thunderstorms are associated with former Tropical Depression 30W that brought heavy rainfall to the Philippines then Indochina over the past 10 days.
Now over the warm waters of the Bay of Bengal, these showers and thunderstorms are becoming more organized around an area of low pressure.
As this area of unsettled weather continues to track westward, it is expected to organize further with the potential to reach tropical storm strength before reaching the eastern coastline of India.
Areas from Vedaranyam northward through Cuddalore and Chennai to near Chirala could receive rainfall from this potential tropical cyclone. The heaviest rainfall will depend on the exact track of the system but is expected from later Friday through the weekend.
The heaviest rainfall will likely average 75-150 mm (3-6 inches) with localized amounts of 250 mm (10 inches). This amount of rainfall will lead to the threat of widespread flooding and mudslides. Any damaging winds appear to be limited to coastal areas near where this potential storm would make landfall.
Areas that were hit by deadly cyclone Phailin earlier this year will be spared from any significant impacts this time around.
