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.
