India Meteorological Department (IMD) has forecast heavy rain in Tamil Nadu and Karnataka and light rain with a cloudy sky for the most part on Wednesday in Delhi and in what is turning out to be the wettest October so far in national capital since the last 66 years.

Massive spells of rainfall are likely to continue over Tamil Nadu for the next five days and over interior Karnataka during the next two days under the influence of these developing systems. Life has been disrupted in both states due to heavy rainfall.

According to the forecast, another cyclonic circulation is developing over Kerala in lower tropospheric levels and over the north Andaman Sea in lower tropospheric levels, which is highly likely to move nearly westwards during the next 3-4 days triggering heavy rainfall.

IMD has predicted a generally cloudy sky with light rain in Delhi on Wednesday as the national capital has recorded its wettest October so far in 66 years.  The maximum temperature during the day is likely to touch 30 degrees Celsius while the minimum temperature might fall to 21 degrees.

Widespread light to moderate rainfall is likely on Wednesday over Sub-Himalayan West Bengal, Sikkim and Bihar.

IMD’s weather bulletin also said that a cyclonic circulation lies over Punjab and adjoining Haryana in lower tropospheric levels which might trigger light to moderate rainfall in the region.
