Chennai on rain alert ahead of possible ‘severe’ Cyclone Montha; low-pressure area likely to intensify
The IMD said on Saturday that a depression over the Bay of Bengal is likely to intensify into a severe cyclonic storm by morning of October 28.
A low-pressure area - that is likely to develop into cyclonic storm and eventually into a ‘severe’ cyclonic storm - is currently looming over the Bay of Bengal and is expected to bring heavy rainfall to Chennai and its adjoining regions.
If and when the weather system intensifies into a cyclonic storm, it will be called ‘Montha’.
An orange alert has been issued for Chennai, Tiruvallur, and Ranipet, with these districts expected to receive very heavy rainfall on October 27.
Will the storm be named Montha?
The India Meteorological Department has predicted that the low-pressure area may develop into a cyclone by Sunday, October 26. Once formed, the storm may be named Montha, a name given by Thailand, meaning “beautiful flowers.”
