"This year´s total August rainfall is heaviest ever since 2002," meteorologist Sudip Kayastha said. In 2002, the Valley had received all-time-heaviest rainfall of 499.9 mm. According to Kayastha, this year´s total August rainfall is second highest since 1968.
"We have been recording rainfall for the last four decades; and this August´s total rainfall is second highest so far," Kayastha said. According to Kayastha, almost all regions of the country received more-than-average rainfalls this August.
According to the MFD, only one of its five regional weather stations, Surkhet, recorded less rainfall than its average. MFD recorded only 303.9 mm rainfall in Surkhet, 108 mm less than its August average. In the rest four MFD stations, August rainfalls surpassed averages.
As always, Pokhara recorded heaviest rainfall of 1187.8 mm this August, more than its average of 849.7 mm. Similarly, Dipayal and Dhankuta weather stations also surpassed their respective average rainfalls of 241.6 mm and 167 mm. MFD recorded 267.6 mm rainfall in Dipayal and 225 mm rainfall in Dhankuta this August.
As August bids adieu, weathermen at MFD say now this year´s monsoon, which arrived one week later than expected, is gradually receding. "Although we have experienced significant amounts of rainfalls in the beginning of September, this year´s monsoon will soon start getting passive," Kayastha said. "Instead, we will witness scattered rainfalls for some days."
With this year´s monsoon slightly receding, the September sky will see more cases of lightings and thunderbolts. Generally, monsoon lightnings and thunderbolts do not take place during heavy rainfalls. The monsoon, caused by temperature differences between sea and land levels, generally stays till the third week of September.
