Issued at 800 AM MST Wed Jun 11 2025 000 WTPZ43 KNHC 111435 TCDEP3 Post-Tropical Cyclone Cosme Discussion Number 13 NWS National Hurricane Center Miami FL EP032025 800 AM MST Wed Jun 11 2025 Drier mid-level air and stable atmospheric conditions have taken their toll on Cosme. The system has been devoid of deep convection for more than 12 hours, with only a swirl of low- to mid-level clouds evident on satellite imagery. The initial intensity has been lowered to 30 kt. Given the hostile environment and ongoing lack of convection, Cosme is not expected to redevelop, and this will be the final advisory. The low is now moving toward the east-northeast at about 070/6 kt. Global model guidance indicates a gradual turn toward the north-northeast later today, followed by a turn to the north on Thursday, as the system steadily spins down and dissipates over the next day or so.
