The cold wave in the city will be missing for some upcoming days. The Regional Meteorological Centre (RMC) recorded minimum temperature at 18.2° Celsius on Friday, which is 3°C above from the normal temperature. The maximum temperature was recorded 31°C.
The reason of such deviation was a western disturbance, the RMC Kolkata experts predicted. "This western disturbance created a whirlwind in North Bengal, which stuck the northerly wind to reach in Bengal," said an expert.
"This whirlwind is basically a cyclonic wind. The immediate fallout of such cyclonic wind is rainfall, which Kolkata has witnessed on Friday morning. We have recorded drizzle in most parts of the city," the expert said.
The temperature will be low at end of this cyclonic wind. It could go down to 12°C in next week," he further added.
However, the weather office earlier informed that temperature may slight increase on coming days. It will be around 14-15°C.
It should be recalled that winter came late this year. The RMC Kolkata studied – in 2016, winter had hit the town more than a fortnight ahead of time — on November 22 — with the hottest first half of November in five decades, making way for one of the coldest second half of November.
However, this year, there were no such weather irregularities. But this cold spell will not continue till end of February month.
