| #888247 (Received by flhurricane at: 10:56 AM 20.Apr.2017) TCDAT1 Tropical Depression One Discussion Number 5 NWS National Hurricane Center Miami FL AL012017 1100 AM AST Thu Apr 20 2017 Conventional satellite imagery indicate that the convection, although not very deep, has become more symmetric around the center, suggesting that the subtropical cyclone has transitioned into a tropical depression. This is supported by AMSU data this morning that shows that the system has developed a weak, but warm core. This transition is a common process, and does not change the previous intensity or track forecasts that call for the depression to become a remnant low later today, and become absorbed by a larger low tonight or early Friday. It is estimated that the depression is producing winds of 30 kt within some convective bands. Since the circulation is already becoming elongated, a weakening trend is likely to begin soon. The depression is moving toward the northwest at 12 kt, and this general motion with a gradual increase in forward speed is expected to continue until dissipation.
