Total rainfall accumulation.
(TWC Met Team)
Monday, October 4: After experiencing record-breaking rains in September, the wet weather conditions are set to march over to October for many parts of India. Even as the parts of South India await the arrival of the northeast monsoon season, the active southwest monsoon rain-bearing systems are likely to fill the gap.
Tamil Nadu, Kerala and Karnataka are in for inclement weather conditions in the coming days as heavy rains have been forecast due to a cyclonic circulation over the southwest Bay of Bengal adjoining Tamil Nadu. A meteorological mix with a trough running through this cyclonic circulation to the east-central Arabian Sea off Karnataka and Kerala coast also produces widespread rains.
Together, the conditions will effectively bring wet weather over the region for the next 2-3 days, as per the India Meteorological Department (IMD).
Among the major cities, Thiruvananthapuram and Bengaluru are expected to witness generally cloudy skies with a few spells of rain or thundershowers for the next two to three days. Chennai is also likely to witness of few spells of thunderstorms with rains this week.
Bengaluru already witnessed a spell of heavy rains on Sunday night, with the city registering 64 mm rainfall till Monday morning. Parts of the city also recorded over 90 mm of rainfall, leading to waterlogging, traffic snarls and falling of trees.
Tamil Nadu, Kerala and coastal and south interior Karnataka are expected to witness heavy rainfall conditions from this Monday to Wednesday. The Weather Channel met team adds that heavy rains would lash parts of South India on the following days: Tamil Nadu on Monday and Tuesday, Kerala between Monday to Wednesday and over south interior Karnataka on Tuesday and Wednesday.
Besides, various other parts of South India are in for fairly widespread to widespread rains and thunderstorms.
Owing to these rough weather conditions, the IMD has issued an orange alert over Tamil Nadu, Puducherry and Kerala for Monday, October 4. The advisory urges residents to ‘be prepared’ for inclement weather.
After that, the wet conditions will likely intensify over Kerala as the IMD has upgraded the alert level to red on Tuesday, which indicates that residents should ‘take action’. Meanwhile, Tamil Nadu, Puducherry and adjoining south interior Karnataka have retained the orange alert for this day.
Come Wednesday, and the extremely rough weather conditions will subside, resulting in a mere yellow watch over the abovementioned places. This level of advisory instructs residents to ‘be updated’ on the weather situation.
The wet conditions may again gain pace over southern states as there are some chances for developing a low-pressure off Karnataka around Thursday.
Since the start of this month, rains have been fairly on and off over the regions of South India. Kerala (56.6 mm), Tamil Nadu (42 mm), Puducherry (30.7 mm) have registered above normal rains, while Karnataka(24.9 mm) have notched ‘normal’ rains when compared to their respective long term average of between October 1 to October 4.
