Post-Tropical Cyclone EIGHT-E Forecast Discussion Number 12
2015-07-30 16:38:10| National Hurricane Center (East Pacific)
Issued at 800 AM PDT THU JUL 30 2015 000 WTPZ43 KNHC 301438 TCDEP3 POST-TROPICAL CYCLONE EIGHT-E DISCUSSION NUMBER 12 NWS NATIONAL HURRICANE CENTER MIAMI FL EP082015 800 AM PDT THU JUL 30 2015 Tropical Depression Eight-E has been devoid of organized deep convection near the center for more than 18 hours, except for an isolated thunderstorm that has recently developed just south of the well-defined circulation center. However, the main band of convection is located in the northeastern quadrant, but it is more than 200 n mi from the center. Therefore, this system no longer meets the criteria of a tropical cyclone; it is being designated as a remnant low, and advisories are being discontinued at this time. The initial intensity remains at 25 kt based on an earlier RapidSCAT overpass. Since the remnant low is heading toward a more hostile environment, the new NHC official forecast is similar to the previous advisory, calling for dissipation in about 24 hours. The remnant low is moving at 270/11 kt. This general motion should continue today, followed by a turn toward the west-southwest by Friday morning. The remnant low is forecast to cross into the Central Pacific Hurricane Center's area of responsibility within the next couple of hours. For additional information on this remnant low please see High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFEPI and WMO header FZPN02 KWBC.
