Francisco’s circulation is quickly becoming poorly defined, and it is possible that the tropical storm could be dissipating. Satellite and scatterometer data indicates that the circulation is becoming stretched out and elongated from southwest to northeast, and the wind field resembles a sharp trough rather than a closed low. Visible satellite imagery indicates the presence of multiple low cloud swirls, with flaring clusters of convection located mainly to the east of the center. There is still discrete banding present, with a very large feeder band extending into the monsoon trough to the south. Although Dvorak and automated estimates are decreasing, the Oceansat-3 pass indicated that 35 to 40 kt winds were occurring north and northeast of the center, so the intensity remains 40 kts.

The forecast remains unchanged. Francisco remains embedded in the monsoon gyre and is expected to continue moving generally northwestward, and it should pass between Miyakojima and Okinawa during the next 12 to 24 hours. Given Francisco’s current state and the fact that the environment will soon get even less favorable with stronger deep-layer shear ahead, Francisco could dissipate at any time during the next couple of days, but the system should definitely dissipate by Saturday as it merges with a broad monsoonal system that will also absorb Typhoon Co-May.
