Rainfall deficit narrows in T.N. this August; subdued showers likely till September 1
Tamil Nadu has seen a reduction in its rainfall deficit this August due to frequent wet spells, though the state expects drier conditions until September 1. The Regional Meteorological Centre forecasts a rise in temperatures in interior regions before rainfall activity potentially increases again in early September.
Why it matters
Accurate weather forecasting is critical for agricultural planning and water resource management in regions sensitive to monsoon fluctuations.
Scattered rainfall across Tamil Nadu almost daily has helped narrow the rainfall deficit this month compared with the shortfall in July. The Regional Meteorological Centre has, however, forecast that the State would witness subdued rainfall till September 1, along with a rise in temperatures over interior parts of the State.
Tamil Nadu has recorded an overall rainfall of nearly 16 cm so far this Southwest monsoon from June 1. Though this is 18% below the average rainfall for the period till Wednesday, the RMC considers this to be within the normal range.
V.R.Durai, Head, Regional Weather Forecasting Centre, RMC, said July alone had recorded a rainfall deficit of nearly 67%, pulling down the seasonal rainfall figures. Frequent wet spells in August have since helped reduce the overall deficit. Some of the districts that are still experiencing a large rainfall shortage include Chengalpattu, Karur, Nagapattinam, Tirupattur and Ramanathapuram.
