ZCZC MIATCDEP4 ALL TTAA00 KNHC DDHHMM TROPICAL STORM DOUGLAS DISCUSSION NUMBER 17 NWS NATIONAL HURRICANE CENTER MIAMI FL EP042014 200 PM PDT WED JUL 02 2014 Convection associated with Douglas is quickly losing its organization. In addition, a 1758 UTC ASCAT-B pass indicated that the maximum winds have decreased slightly, and the initial intensity is set at 35 kt for this advisory. Visible satellite images show that dry and stable air continues to infiltrate into Douglas's circulation, and along with decreasing sea surface temperatures, will contribute to additional weakening during the next couple of days. Douglas is now forecast to become a tropical depression in 12 hours and degenerate into a remnant low by 36 hours. Douglas is creeping north-northwestward with an initial motion of 330/2 kt. However, the cyclone is expected to turn back to the northwest later tonight and eventually accelerate to the west-northwest by 48 hours when mid-level ridging builds over the western United States. Low-level ridging is forecast to steer the remnant low west-northwestward to westward between days 3 and 5. The track guidance is tightly clustered on this advisory cycle, and no significant changes were required to the NHC track forecast.
