TS Nanmadol and TY Talas Update

Tropical Storm Nanmadol continues to move very slowly across the Taiwan Strait. It was last located approximately 115km east southeast of Xiamen or about 180km southwest of Taipei. Maximum sustained winds remain at 100kph with gusts of up to 140kph. Nanmadol is moving northwestward at 10kph.

All Signal Warnings for the Philippines have now been dropped by PAGASA.

TS Nanmadol is on its way to making landfall in the Fujian Province later tonight, less than 50km away from Xiamen. It will then continue moving inland across China and should dissipate as early as Thursday. Expect rainfall amounts of up to 200mm across SE China with storm surges of up 4 to 6 feet along coastal areas.

Rainfall continues to fall across Southern Taiwan. Latest rainfall reports from that country range from 100-200mm. Areas across Western Taiwan also continue to experience tropical storm force winds although conditions there should improve today.

Talas, on the other hand, has strengthened is now upgraded to a typhoon by the JMA. It is still well south of Japan at the moment although the storm has begun to turn to the northwest. Maximum sustained winds are now 120kph gusting to 150kph. Typhoon Talas is moving northwestward at 10kph.

Forecasts continue to point at a Honshu Landfall by Friday perhaps as a Category 1 Typhoon. There are still large disparities among models, however, including exact landfall point and the timing. We will discuss more on the forecast later in our 3pm update.
