Latest satellite image shows convective activity beginning to consolidate near the circulation center. Banding has also improved over the past few hours. Nepartak is moving in an area of low wind shear and high sea surface temperatures which will only help the system gain strength over the coming days.
Tropical Storm Nepartak is forecast to move northeastward over the Philippine Sea and will be named Bagyong Butchoy as it enters the PAR by Tuesday morning.. As of this time, the computer model consensus does not show Nepartak directly affecting the Philippines. However, the southwest monsoon (Habagat) may be enhanced bringing higher chances of rainfall across the country.
Tropical Storm Nepartak is also forecast to continue intensifying and may reach typhoon-intensity by the middle of this week. Long-range forecasts also show Nepartak possibly affecting Eastern Asia by the end of this week.
