IMD’s prediction
IMD predicts that isolated exceptionally heavy rain may fall throughout Meghalaya on Tuesday (May 17).
The India Meteorological Department warned on Monday, “This is owing to strong southwesterly winds at lower tropospheric levels from the Bay of Bengal to Northeast and neighboring east India.”
A cyclonic circulation can be found over the Lakshadweep Islands in the middle troposphere, and another can be found over the north Tamil Nadu coast in the lower troposphere.
Moreover, there are cyclonic circulations and a strong lower-level westerly flow from the Arabian Sea under their influence.
Meanwhile, the India Meteorological Department bulletin also predicted widespread light/moderate rainfall with isolated thunderstorms/lightning/gusty winds, as well as isolated heavy to very heavy rainfall over Kerala, coastal and south interior Karnataka over the next four days, isolated heavy rainfall over Tamil Nadu until May 18, and isolated heavy rainfall over the Lakshadweep area on Tuesday.
On May 18, isolated exceptionally heavy rainfall is expected throughout coastal and south interior Karnataka.
