Three days, heavy to very heavy rain forecast for TN, Rayalaseema, AP coast
The low-pressure area that formed on Wednesday in the southwest Bay of Bengal off Sri Lanka’s coast is still there on Thursday, and the India Meteorological Department (IMD) says it will likely get stronger by Friday. Until Saturday morning, the ‘low’ is expected to move toward the coasts of Tamil Nadu and Puducherry. The IMD said that after it crossed the coast, it would move west-northwest across Tamil Nadu and Puducherry and then move next to Kerala on Saturday and Sunday.
This may lead to a follow-up
IMD’s numerical model predicts that the system will just touch the northern parts of Sri Lanka before moving into Tamil Nadu and then moving to hit Kerala. From here, it would go out into the southeast Arabian Sea and get some repairs. Importantly, it would leave a trail of moisture over the Bay of Bengal and cause a stronger weather system to form by November 18.
The US agency said
The US National Centers for Environmental Prediction say that it could rain heavily or very heavily along the coasts of Tamil Nadu and Andhra Pradesh in the week ending on November 18. (Friday next). The heavier rains could spread to parts of North Coastal Tamil Nadu (around Chennai), South Coastal Andhra Pradesh, Telangana, North Interior Karnataka, and parts of West Maharashtra over the next week. This could happen right before the end of the month.
Rain that is heavy to very heavy
The IMD also said that the current ‘low’ will bring fairly widespread to widespread rain, with isolated heavy to very heavy rain over Tamil Nadu, Puducherry, Karaikal, Rayalaseema, and south coastal Andhra Pradesh for three days starting on Friday, and isolated heavy rain over Kerala and Mahe from Friday to Monday, following the path of the weather system. It might also rain very hard in places like Chennai, Puducherry, and Karaikal in North Coastal Tamil Nadu on Friday, and in North Tamil Nadu, Puducherry, and Karaikal on Saturday.
Warning message to fisherman
During the next three days, the intensified ‘low’ will bring squally weather with wind speeds of 40-45 kmph gusting to 55 kmph (depression-strength) over the south-west and adjoining West-Central Bay (off the Tamil Nadu and Andhra Pradesh coasts); along and off the south Andhra Pradesh-Tamil Nadu, Puducherry, and Sri Lanka coasts; the Gulf of Mannar and the adjoining Comorin area; At the same time, fishermen are told not to go into these areas during the depression. In an extended IMD forecast, it was said that many parts of the South Peninsula, the Islands in the Bay, and the Arabian Sea are likely to get light to moderate rain. This seems to be a reference to the formation of the second ‘low.’
