Tropical Depression 05W has intensified and has been upgraded to Tropical Storm Peipah by the Japan Meteorological Agency. This system was last located approximately 740km east southeast of Palau. Maximum sustained winds are now at 65kph with gusts of up to 85kph. TS Peipah has also slightly accelerated and is now moving west northwestward at a speed of 20kph.

Latest satellite image shows a more robust looking cyclone with strong convective activity in and around the storm center. Easterly wind shear is still dispersing the higher cloud tops to the western periphery. However, good equatorward outflow is helping to somewhat offset the effects of the said moderate wind shear.
Tropical Storm Peipah will soon affect Palau and Yap later today. Seas in the region will be rough and winds should start increasing in the said areas. Rain will also be a factor especially for Palau which could get as much as 200mm this weekend.
TS Peipah should also be entering the Philippine Area of Responsibility by tomorrow (Saturday) and will, then, be given the local name 'Bagyong Domeng' by PAGASA. This system could, then, start impacting the Philippine Islands by Sunday and into Monday.
We'll have another update later this afternoon.
