Post-Tropical Cyclone DOUGLAS Forecast Discussion Number 28
2014-07-05 17:11:05| National Hurricane Center (East Pacific)
Issued at 800 AM PDT SAT JUL 05 2014 000 WTPZ44 KNHC 051510 TCDEP4 POST-TROPICAL CYCLONE DOUGLAS DISCUSSION NUMBER 28...CORRECTED NWS NATIONAL HURRICANE CENTER MIAMI FL EP042014 800 AM PDT SAT JUL 05 2014 Corrected capitalization in last paragraph. Douglas remains devoid of deep convection, and since the sea surface temperatures are below 22 deg C, there is little likelihood of the system making a comeback. Therefore the system is being declared a remnant low, and this is the last advisory. The large circulation has been slow to spin down, but gradual weakening is anticipated with the cyclone expected to dissipate in about 72 hours. The initial motion continues northwestward at about 8 kt. Post-tropical cyclone Douglas should continue to be steered by the flow on the south side of a low- to mid-level subtropical ridge. The track guidance generally shows a turn toward the west-northwest with a slight decrease in forward speed over the next couple of days, and so does the official forecast. For additional information on the remnant low of Douglas, please see High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFEPI and WMO header FZPN01 KWBC.

Post-Tropical Cyclone ARTHUR Forecast Discussion Number 19
2014-07-05 17:01:06| National Hurricane Center (Atlantic)
Issued at 1100 AM EDT SAT JUL 05 2014 000 WTNT41 KNHC 051500 TCDAT1 POST-TROPICAL CYCLONE ARTHUR DISCUSSION NUMBER 19 NWS NATIONAL HURRICANE CENTER MIAMI FL AL012014 1100 AM EDT SAT JUL 05 2014 Surface, satellite, and earlier NOAA reconnaissance aircraft data indicate that Arthur became an extratropical cyclone by 1200 UTC this morning. The earlier aircraft reports and recent wind observations show that the cyclone continues to weaken, and the initial intensity is lowered to 50 kt. The post-tropical cyclone should continue to weaken during the next day or so and winds are expected to be below gale force in 48 to 72 hours. The cyclone is now forecast to dissipate by the end of the forecast period. The cyclone is moving north-northeastward at about 21 kt. A north-northeastward to northeastward motion at a slower forward speed is expected during the next day or so. A turn toward the north and a further reduction in forward speed is forecast in a few days. The lastest track forecast is similar to the previous forecast through 48 hours, but has been adjusted westward thereafter to be in better agreement with the latest track guidance. This will be the last NHC advisory on Arthur. For additional information, including warnings, consult products issued by the Canadian Hurricane Centre at: weather.gc.ca/hurricane/index_e.html Statements on the post-tropical cyclone are also being issued by the Canadian Hurricane Centre under WMO header WOCN31 CWHX and in French at WOCN41 CWHX. For marine interests, additional information can be found in High Seas Forecasts issued by the National Weather Service under AWIPS header NFDHSFAT1 and WMO header FZNT01 KWBC.
