Rain brought by a stationary front that arrived on Thursday has temporarily relieved a water shortage in central and southern Taiwan as many of the reservoirs had significant inflows of water yesterday.
Statistics from the Water Resources Agency (WRA) showed that the Feitusei Reservoir in Taipei County had accumulated 98.7mm of rain on Thursday alone. The Shimen Reservoir in Taoyuan County and the Baoer Reservoir in Hsinchu County also accumulated rainfall of 66.9mm and 29mm respectively on the same day.
The Feitsuei Reservoir was at 64.1 percent of capacity, while the two other reservoirs were at less than 30 percent capacity.
The WRA estimated the front could bring approximately 7 million tonnes of water to the Feitusi Reservoir in the days to come.
The accumulated inflow in Shimen, Baoer, Liyutan and Tsengwen could also top 1,200mm, 100mm, 200mm and 500mm respectively, it said.
WRA Deputy Director-General Wu Yueh-hsi (吳約西) said that his agency is scheduled to hold a meeting on Monday to decide if it should postpone phase-two water rationing.
As the nation will still be under the influence of the stationary front next week, Wu said the WRA would continue with rain-making efforts in areas with a serious water shortage if the weather conditions persist.
Central Weather Bureau forecaster Lin Ding-yi (林定宜) said the front had mainly affected the north of the nation when it arrived on Thursday. He added that the front had moved further into central and southern Taiwan yesterday, bringing rain to Greater Tainan, Chiayi, Nantou and Hualien counties.
The weather bureau’s observation -station near the Tsengwen Reservoir also accumulated 71.5mm of rainfall by 5pm yesterday, he said.
With the front moving south, the weather bureau issued a warning for heavy to torrential rain across the nation, adding that lightning strikes, landslides and mudflows might also be possible.
Lin said the front is forecast to linger until Wednesday.
“The weather will be unstable during this period of time, and the chances of rain will be high nationwide,” Lin said. “Heavier rain is likely to occur on Monday and Tuesday next week, when the front will contain more moisture. People in central and southern areas can still hope for more rain to come.”
