Finally, there’s some rain on the horizon for Tamil Nadu

Changing weather system may lead to showers in southern, western parts of TN

Some relief: According to weather bloggers, a few places in the State may experience heavy showers.

After a prolonged dry spell, rainfall activity may revive in some parts of Tamil Nadu from Wednesday.

According to the India Meteorological Department, the trough of low pressure over south Bay of Bengal and adjoining equatorial Indian Ocean may bring some rainfall, particularly over the southern districts of the State.

While a few places in the south may begin to get rainfall from Tuesday, north Tamil Nadu and Puducherry may receive some rain from Thursday.

However, Chennai, currently reeling under a near water-starvation situation, may not actually benefit much from this rain spell.

On Monday, weather observatories in Nungambakkam and Meenambakkam recorded a maximum temperature of 31 degrees Celsius and 31.2 degrees Celsius, which was close to normal temperature.

Weather bloggers and meteorology enthusiasts note that this spell would bring considerable rains. Pradeep John, who runs the popular Facebook page ‘Tamil Nadu Weatherman’, said the southern and western parts of the State may get moderate to heavy showers.

This weather system may provide significant rainfall, exceeding the normal rainfall of 20 mm in March. He pointed out that Tamil Nadu got 170 mm of rainfall in March 2008 and 55 mm in March 2006.

Citing IMD data since 1951, K. Srikanth, who blogs at Chennaiyil Oru Mazhaikalam, said the State had received excess rainfall for 21 years in March.

“This means Tamil Nadu has been getting more than 20 mm of rain in March once in three years,” he said.
