077 WTPZ43 KNHC 110833 TCDEP3 Tropical Storm Cosme Discussion Number 12 NWS National Hurricane Center Miami FL EP032025 200 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 several hours and is expected to become a remnant low later this morning. Dvorak intensity estimates continue to decrease accordingly. A 11/0442 UTC ASCAT pass showed winds in the 35-40 kt range in the southern semicircle. Assuming additional weakening after that time, the initial intensity is set at 35 kt. After transitioning to a remnant low later this morning, Cosme is expected to dissipate by late Thursday or Friday. The storm is now moving slowly toward the northeast. A gradual turn to the north-northeast with some acceleration is expected later today, followed by a turn to the north on Thursday. Only a slight eastward adjustment was made to the previous NHC track forecast, with no significant changes to the intensity forecast.
