As of 5am this morning, PAGASA has issued Public Storm Warning Signal #3 for Batanes Group of Islands. Signal #2 for Calayan and Babuyan Group of Islands. Signal #1 is up for Cagayan, Ilocos Norte, and Apayao. These provinces should continue to expect strong winds and heavy rains particularly in the Batanes Islands. Weather should begin to improve later tonight and into tomorrow.

Latest satellite image shows the eye of Jelawat has become smaller and more rugged. The inner core of the typhoon is starting to decay as it interacts with stronger wind shear and cooler waters. The outer rain bands continue to impact Batanes Islands bringing rains of up to 30-50mm last night. Much of the rainbands have stayed east of Taiwan but scattered light rains are still being reported along the coast. Aside from the rains, tropical storm gusts continue to be reported across the area along with very rough waves.
Radar from JMA
Outer rain bands from Jelawat are also beginning to impact the Yaeyema Islands which could bring 10 to even 20mm of rain in an hour. As much as 100 to 200mm could fall in these islands in the next 2 days. Aside from the rains, strong winds are beginning to be reported across Yaeyema as well with some stations now receiving sustained Tropical Storm-force winds of 60 to 80kph along with occasional gusts of above 100kph. These rains and winds will continue to increase in intensity throughout the day today with the worst expected around Ishigaki and Yaeyema later tonight where sustained typhoon-force winds of up to 140kph are possible.

Super Typhoon Jelawat will continue to move north and then turn to the northeast later today. It should also weaken below super typhoon strength but still a Category 4 as the inner structure continues to erode. Typhoon winds are possible across Yaeyema Islands tonight and into tomorrow along with heavy rains. By early Saturday morning, we expect Jelawat to weaken to a Category 3 and by Saturday afternoon, it could move near Okinawa, or even make landfall in that island as a Category 2 Typhoon capable of bringing strong winds of up to 160kph along with heavy rains.
Jelawat should accelerate to the northeast by Sunday and eventually make landfall in Honshu by Monday morning as a weakening Tropical Storm.
We'll have another update later this afternoon. For more info on our forecasts, you can watch our Video (issued Yesterday) below.
