The Southwest monsoon will arrive over the South Andaman Sea, Nicobar islands, and Southeast Bay of Bengal Sunday, the India Meteorological Department has said. Once realised, the monsoon will arrive over the islands nearly a week ahead of its normal schedule.
As the monsoon winds are likely to strengthen over these regions in the coming days, the islands are set to experience enhanced rainfall with warning of heavy spells (64.5mm to 115.4mm in 24 hours) during the next five days accompanied by thunderstorms and lightning.
In fact, the Met department has placed Kerala and Tamil Nadu along Mahe and Lakshadweep on a high alert ahead of the heavy to very heavy rainfall (64.4mm to 204.4mm in 24 hours) forecast till Monday.
