THIRUVANANTHAPURAM: In an indication of the southwest monsoon shedding its initial sluggish phase, the number of districts with rainfall deficit has come down from four to two, thanks to the heavy rains which lashed the state over the last one week.

 Except Thiruvananthapuram and Kollam districts, which recorded a deficit of -36 and - 20 per cent respectively, seasonal rainfall in all other districts is now in the ‘normal’ category.

Last week, Alappuzha and Kasaragod were also in the ‘deficit’ category but the heavy rainfall helped these districts move to ‘normal’.
