Front to bring showers to western Taiwan next week

2024-05-23

Plum rain fronts are bringing instability to the weather all over Taiwan, with intermittent rains around the island. That’s set to ease on Saturday as the front moves away, providing a brief spell of good weather. But another front will sweep in next week, bringing showers to the western half of the island.

A passing front is bringing unstable weather to Northern Taiwan, with on and off showers through the day.

From tomorrow on, the front will gradually move away and weaken. So the random downpours will become less frequent, and we’ll return to just afternoon thundershowers.

Another plum rain front is expected to arrive next week. Its impact will be most significant on Tuesday, with heavy rains expected in the western half of the island. Over to the south in the Philippine Sea, the first tropical storm of the season could be about to form.

We expect it to take form and strengthen into the first tropical storm of the year. In the short term, it will draw closer to Luzon Island, before moving north next Monday and Tuesday and then veering northeast toward the Ryukyu Islands. That’s the most likely course based on our assessments, and we don’t expect any direct impact on Taiwan in the short term.

This latest plum rain front brought 41.49 million tons of water to Taiwan’s reservoirs from Monday to Thursday morning. The biggest gains were in the northern Feitsui Reservoir, where water levels rose by 19.1 million tons. Officials say the reservoir now has enough water to supply for three months without shortages. Shihmen Reservoir in Taoyuan gained 3.4 million tons of water, and the Sun Moon Lake and Wushe Reservoir gained a total of 4 million tons. The rains did not replenish reservoirs in the south as much, but hopes are high that the next wave of plum rains will top them up.

今年首颱"艾維尼"恐生成下週鋒面報到西部防大雨

2024-05-23

受梅雨鋒面影響，各地天氣不穩定，雨勢斷斷續續，氣象署預估要等到週六，鋒面才會正式遠離，然而，好天氣持續不久，緊接著下週又將迎新一波鋒面，估計將為西半部地區帶來雨勢，至於目前在菲律賓東方海面，有機會生成今年第1號颱風"艾維尼"。

北部地區受到鋒面影響，天氣依舊不穩定，各地斷斷續續下雨。

“明天之後，鋒面會逐漸地遠離，強度也會減弱，所以各地這種不定時陣雨的情況會慢慢減少一些，逐漸恢復成午後雷陣雨的天氣型態。”

到了下週又有梅雨鋒面接近，下週二影響最大，西半部要嚴防大雨。另外，目前在菲律賓海面上，有機會生成今年的第一號颱風"艾維尼"。

“我們預估它會慢慢地發展增強，也有可能形成今年的第一個颱風。短時間內它是逐漸往菲律賓的呂宋島接近。下週一週二它會逐漸地往北，再往東北、往琉球南方海面前進，以目前的資訊評估，這樣的機率是最大的，所以短時間之內，對台灣並沒有直接的影響”

至於這波梅雨鋒面從20號到23號早上，共為全台帶來4149萬噸水量，其中，受益最大是北部的翡翠水庫，一口氣進帳1910萬，翡管局評估，不只未來3個月內供水沒問題，今年也不會缺水。另外，桃園石門水庫也有340萬噸，中部日月潭及霧社水庫合計也進帳400萬噸，不過，南部地區因降雨相對較少，水庫進帳沒有這麼多，只盼下波鋒面，能再帶來更多水情。
