At 400 PM CDT (2100 UTC), the remnants of Grace were located near latitude 19.6 North, longitude 100.1 West. The remnants are moving toward the west near 13 mph (20 km/h) and this general motion is expected to continue tonight. Maximum sustained winds are near 25 mph (35 km/h) with higher gusts. Although Grace has dissipated, its remnants will likely move into the eastern North Pacific by Sunday afternoon, where it is likely to develop into a new tropical cyclone next week. The estimated minimum central pressure is 1002 mb (29.59 inches).

The mountainous terrain of Mexico has taken its toll on Grace. Surface observations and high-resolution visible satellite images indicate that the system no longer has a definite surface circulation, and Grace has degenerated into a trough to the west of Mexico City. Therefore, this is the last advisory on this system.

Although the surface center has dissipated, the mid-tropospheric remnants of Grace are expected to continue westward, and to emerge into the eastern Pacific Ocean by late Sunday. There is high likelihood that this will lead to the formation of a new tropical cyclone over that basin by early next week.
