Latest satellite image shows strong convective activity forming in and around the circulation center. Banding is also improving and we could see the system being upgraded into a Tropical Storm overnight. TD 13W is located in a favorable environment in the Pacific and should continue to intensify over the next few days.
Tropical Depression 13W is forecast to continue moving generally westward and may approach the Northern Marianas Islands later this weekend. There is a high possibility for this system to become a Typhoon in the next 2 to 3 days as well. Longer range forecasts show a track that may take 13W towards the Southern Japanese Islands by the early part of next week.
We'll have another update tomorrow morning.
