Lekima Strengthens into Severe Typhoon|利奇馬增強為強颱 氣象局上午5縣市陸警

Typhoon Lekima has strengthened into a severe typhoon, and the Central Weather Bureau issued land warnings for Keelung, New Taipei City, Taipei, Yilan, and Hualien on the morning of Aug. 8. According to its forecast, Taiwan will bear the brunt of the typhoon between the evening of Aug. 8 and Aug. 9.

Typhoon Lekima has strengthened to a severe typhoon, and the Navy has dispatched assault amphibious vehicles to Suao Township in Yilan County to be on call and help out with any disaster relief work. The Central Weather Bureau's satellite images show Typhoon Lekima's eye is extremely clear, and its wind radius has expanded slightly. At present, its center is located over the open sea at a distance of 520 kilometers to the southeast by east of Taipei. It is currently moving at a speed of 15 kilometers per hour in a north-northwesterly direction. The typhoon's wind circle is gradually approaching the waters off of eastern Taiwan. The CWB has issued land warnings for Keelung, New Taipei City, Taipei, Yilan, and Hualien.

It will maintain its intensity or may strengthen slightly as it gradually approaches us. With regards to the predicted path, we are forecasting that it will pass over the waters off of northeastern Taiwan, and the odds of it heading towards the waters off of northern Taiwan are the highest. The overall environment's guiding airflow is more complicated, and of course we are not ruling out that it could approach northern Taiwan. During this process, if there are small changes to the guiding airflow, then its path may bring it slightly closer to Taiwan or slightly farther from Taiwan. Both of these situations remain possibilities.

The CWB says the northern and eastern regions will see intermittent rain starting on Aug. 8 due to the effects of the typhoon. The intensity of the rain will increase at night. Taiwan will bear the brunt of the typhoon between the evening of Aug. 8 and Aug. 9. The CWB has therefore issued wind and rain forecasts for those regions affected by the land warnings. During the next 24 hours, the rainfall could reach 250 to 300 millimeters in Taipei, New Taipei City, Keelung, Taoyuan, and Hsinchu, and other regions will see rainfall of 50 to 150 millimeters. Outlying islands, with the exception of Orchid Island and Green Island, will see rainfall of less than 50 millimeters.

The cities and counties of Taipei, New Taipei City, Hualien, and Yilan, and the region from Hsinchu in the north to Keelung will probably be covered by the wind circle. The rainfall will be the heaviest on Friday, and will probably finish falling in two days. With regards to the south, there will probably be a clear southwest circulation and it will rain from Friday afternoon until Sunday.

The CWB forecasts the typhoon will begin moving away from Taiwan on Aug. 10, although its south side will still have plenty of water vapor and there will be a chance of heavy or torrential rain falling over the central and southern regions. The public is therefore reminded to remain vigilant.

利奇馬來勢洶洶已由中颱轉為強颱,海軍的AAV7兩棲登陸突擊車進駐宜蘭蘇澳待命救災,因為從氣象局的衛星雲圖可以看見它的颱風眼相當明顯,暴風半徑也稍微擴大,目前中心位置在台北東南東方約520公里海面上,以每小時15公里速度,向北北西移動,暴風圈正逐漸接近台灣東半部海面,包括基隆、新北、台北、宜蘭、花蓮,都是都是首波的警戒範圍。

氣象局預報中心課長 羅雅尹表示:「逐漸接近我們的過程當中,強度以維持,或者是不排除還有稍稍增強的空間,預測路徑來講,是以通過台灣東北部海面,到北部海面機率是最大,台灣所處的整個大環境的導引氣流,是比較複雜的當然也不排除,它可能在接近台灣北方,這段過程當中,如果導引氣流有些微的變化,它的路徑可能稍微偏向台灣一點,或是偏離台灣一點,這個都還是有可能。」

氣象局表示,受到颱風外圍環流的影響,白天開始,北部、東北部斷斷續續有雨勢,越晚降雨會越明顯,晚間到週五是利奇馬對台灣的影響最大的時候,因此也針對陸警範圍發布風雨預報,在未來24小時北北基、桃園、新竹平地雨量最高可達250到300毫米,其他地區雨量為50到150毫米不等,離島地區除了蘭嶼、綠島外則均低於50毫米。

天氣風險公司總經理彭啟明表示:「雙北、花蓮、宜蘭,一直從新竹以北到基隆,其實這些縣市大概都會,被暴風圈所籠蓋住,雨勢來說的話,還是以禮拜五最多的,大概集中在兩天下完,南部來說的話,大概會有明顯的西南環流,從禮拜五的下半天,一直下,下到禮拜天。」

氣象局預估,颱風可望在週六逐漸遠離台灣,但颱風南側水氣豐沛,台灣中南部仍持續有大雨或豪雨發生的機率,民眾千萬不能掉以輕心。
