Surface synoptic observations suggest that the cyclone is now of, at most, minimal tropical storm strength. These tropical-storm-force winds may be occurring over a small inland area near the center. Continued weakening is expected, and Gordon should become a tropical depression later this morning. Gordon continues moving northwestward, with an initial motion estimate of 325/12. The cyclone should continue on a northwestward heading with a decrease in forward speed, along the southwestern periphery of a mid-level ridge, for the next couple of days. Later in the period, Gordon's remnant is forecast to turn northward and northeastward with increasing forward speed as it approaches the mid-latitude westerlies north of 40N. the official forecast track is close to the latest dynamical model consensus, TVCA. All coastal watches and warnings associated with Gordon are being discontinued at this time. Key Messages: 1. Heavy rainfall from Gordon will affect the western Florida Panhandle, southwest Alabama, southern and central Mississippi, northeastern Louisiana, Arkansas, Missouri, southern Iowa and Illinois, with isolated maximum amounts of 12 inches through early Saturday. This rainfall will cause flash flooding across portions of these areas.
