Mandous is expected to emerge over the Arabian Sea early next week and travel for a few days, but it won’t intensify again into another tropical cyclone
Cyclone Mandous is heading for landfall between Puducherry and Chennai between 12 midnight and 6 am IST December 10, 2022. It has already attained its peak intensity and is weakening now as it moves over cooler sea and faces friction from the land.
After crossing the coast, it will rapidly weaken and move towards the southern parts of Andhra Pradesh and Karnataka, following which it is expected to emerge over the Arabian Sea early next week and travel for a few days, but it won’t intensify again into another tropical cyclone.
The coastal parts of Tamil Nadu, Puducherry and Andhra Pradesh will witness windy weather (peak wind speeds could be up to 70 kilometres per hour) December 9, with winds relaxing from December 10 after the landfall.
The coastal parts of Tamil Nadu, Puducherry and Andhra Pradesh will receive heavy rainfall December 9 and 10. The impacts would be felt in southern Andhra Pradesh and Karnataka, which would also get heavy rainfall December 10 after the landfall.
Overcast conditions and rains would reduce the temperature in these areas. The landfall region will get the heaviest rainfall, with some places getting more than 200 mm rainfall in the entire period.
In comparison, places in southern Andhra Pradesh and Karnataka will get mostly up to 100 mm rainfall. Moderate rainfall is expected over the rest of Tamil Nadu, Andhra Pradesh and Kerala. Goa and the southern parts of Maharashtra will get light rainfall for a few days from December 11.
The low-pressure will impact Maharashtra’s weather, leading to a lot of cloud cover and light rains which will continue until mid-December. Cloudy conditions with a bit of light rain can’t be ruled out in Mumbai early next week.
