Another cyclone? IMD warns Southern states of another storm on Dec 2

Just days after being in the firing line of Cyclone Nivar, which landed over Tamil Nadu as a Very Severe Cyclonic Storm during the early hours of November 26, Southern Peninsular India must now brace for another potential cyclone this coming week.
According to the India Meteorological Department (IMD), a low pressure area currently lies over South Andaman Sea and the adjoining areas of Southeast Bay of Bengal and Equatorial Indian Ocean. From here on, the system is likely to concentrate into a depression during the next 48 hours, and continue intensifying further, thereafter.
As it does so, it is expected to move westwards, and reach the south Tamil Nadu coast around Wednesday, December 2. The Weather Channel’s met team predicts the system will move across these aforementioned states as a deep depression or a cyclonic storm on Thursday.
Under this system’s influence, scattered to widespread rainfall activity is expected over Tamil Nadu, Puducherry, Karaikal, Kerala, Mahe, Lakshadweep, south coastal Andhra Pradesh, and south Rayalaseema on Tuesday and Wednesday, December 1-2.
Furthermore, isolated heavy to very heavy showers, along with moderate thunderstorms and lightning, have been forecast over Tamil Nadu, Puducherry and Karaikal on December 1-2. Isolated heavy falls with moderate thunderstorms and lightning are also on the cards for south Coastal Andhra Pradesh on Tuesday and Wednesday, and over Rayalaseema and Lakshadweep area on just Wednesday.
In view of these predictions, the IMD has issued an orange alert over Tamil Nadu, Puducherry, and Kerala; and a yellow watch across Coastal Andhra Pradesh, Rayalaseema, and South Interior Karnataka on December 1 and 2. The orange alert instructs residents to ‘be prepared’ for rough weather, while the yellow watch urges people to ‘be aware’ of the local weather situation.
Between the months of October and December, the formation of cyclones in the northern Indian Ocean tends to be a fairly common occurrence. But with the La Niña years currently ongoing, coupled with the rising land and sea temperatures around the globe, the frequency of intense cyclones over the Bay of Bengal is expected to be much higher than normal this winter.
Meanwhile, as the northeast monsoon and the cyclone seasons continue, all states across southern India are likely to experience abundant rainfall during this year-end period. So far, since the beginning of October, Tamil Nadu (294.4 mm), Puducherry (589.3 mm), and Karnataka (195.3 mm) have all recorded ‘normal’ rainfall as compared to their respective long-term average figures for the period between October 1 and November 28.
In the same time frame, the likes of Andhra Pradesh (335.3 mm) and Telangana (174.5 mm) have registered ‘excess’ precipitation, whereas Kerala, at 314.3 mm, has recorded a ‘deficit’ in its rainfall activity.
