Sea warning for Nanmadol likely early Saturday: CWB

Taipei, Aug. 26 (CNA) The Central Weather Bureau (CWB) said Friday it was likely to issue a sea warning for Typhoon Nanmadol early the following day, depending on its speed.

The threat from Nanmadol had increased over the past 24 hours as expected interaction between Nanmadol and Tropical Storm Talas, also in the region, did not happen, the bureau said.

The CWB was anticipating that a "Fujiwhara effect" -- under which two nearby storms tend to merge into a point between the two systems -- would pull Nanmadol eastward toward Talas and away from Taiwan.

But according to CWB data, as of 8 a.m., the distance between the two storms was about 1,700 km, a 100 km increase compared with 24 hours earlier.

"The chances of a Fujiwhara effect are very unlikely now, which increases Nanmadol's danger as it keeps moving toward us," said forecaster Hsieh Min-keng.

As of 8 a.m., Nanmadol was centered 690 km south-southeast of Taiwan's southernmost point of Eluanbi, moving in a north-northwesterly direction at a speed of 9 km per hour.

Meanwhile, Talas was centered 1,900 km east of Taiwan and was continuing to move northward. It is not likely to pose a threat to Taiwan, the bureau said. By Lee Hsin-Yin)
