| #888212 (Received by flhurricane at: 10:44 PM 19.Apr.2017) TCDAT1 Subtropical Depression One Discussion Number 3 NWS National Hurricane Center Miami FL AL012017 1100 PM AST Wed Apr 19 2017 The subtropical depression has changed little in strength since formation occurred earlier today. Deep convection is confined to a small area over the northwestern quadrant. A pair of recent ASCAT passes indicated that the maximum winds are still near 30 kt. These data also showed that the wind field of the system has contracted since the earlier ASCAT passes this morning. The cyclone has been moving northeastward at 10 kt during the past 6 to 12 hours. A large extratropical cyclone is approaching the system from the west-northwest, and it should cause the depression to turn northward and then northwestward overnight and on Thursday. Little change in strength is likely before the system dissipates due to cold water and continued moderate shear. The models are in excellent agreement, and show the extratropical low absorbing the subtropical depression, or its remnants, in a day or so.
