Tropical Storm Pewa Update #2

Issued (02 UTC) 10am PhT 081913

The tropical cyclone that crossed the International Date Line earlier, Tropical Storm Pewa, continues to intensify as it moves across the Western Pacific Basin. It was last located approximately 1,420km southeast of Wake Island. Maximum sustained winds are now up to 110kph with gusts of up to 140kph. TS Pewa is moving northwestward at 15kph.

Tropical Storm Pewa is now nearing Typhoon intensity with a pinhole eye starting to appear on satellite imagery. Pewa itself is a very small cyclone with a diameter of about 250km. The small nature of Pewa could lead to fluctuations in intensity as it progresses to the northwest. Nevertheless, we expect further intensification as conditions in the region become more favorable.

Tropical Storm Pewa is forecast to move northwestward towards Wake Island and could approach the area by Wednesday. As mentioned above, Pewa could intensify into a Typhoon later today and could even become a Category 3 as it moves near Wake Island by Wednesday.

We'll have another update later tonight.
