Post-Tropical Cyclone ALEX Forecast Discussion Number 9
2016-01-15 21:32:46| National Hurricane Center (Atlantic)
Issued at 500 PM AST FRI JAN 15 2016 000 WTNT41 KNHC 152032 TCDAT1 POST-TROPICAL CYCLONE ALEX DISCUSSION NUMBER 9 NWS NATIONAL HURRICANE CENTER MIAMI FL AL012016 500 PM AST FRI JAN 15 2016 Geostationary and low-level microwave satellite images show the cloud pattern becoming elongated and taking on a comma, i.e. frontal, shape. Short-term model forecasts show significant thermal advection in the circulation, and this is also suggested by surface data. An earlier scatterometer pass showed that the system was losing its inner-core wind maximum, with the strongest winds well-removed to the northeast of the center. Therefore Alex has made the transition to an extratropical cyclone, and this will be the last advisory. Maximum winds are estimated to be just below hurricane strength, and the post-tropical cyclone could re-intensify slightly in the short term due to baroclinic energy sources. Within 48 hours, the global models generally agree on the system merging with another extratropical low over the north Atlantic. The cyclone has accelerated greatly during the day and is now moving slightly west of due north, or 350/35. The dynamical guidance shows the system rotating counterclockwise around a large gyre over the north Atlantic during the next day or so. This is also shown in the official forecast, which is based mainly on input from the NOAA Ocean Prediction Center. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and available on the Web at http://www.opc.ncep.noaa.gov/shtml/NFDHSFAT1.shtml, and in high seas forecasts issued by Meteo France under WMO header FQNT50 LFPW and available on the web at http://www.meteofrance.com/previsions-meteo-marine/bulletin.

Tropical Storm ALEX Forecast Discussion Number 8
2016-01-15 15:57:13| National Hurricane Center (Atlantic)
Issued at 1100 AM AST FRI JAN 15 2016 000 WTNT41 KNHC 151457 TCDAT1 TROPICAL STORM ALEX DISCUSSION NUMBER 8 NWS NATIONAL HURRICANE CENTER MIAMI FL AL012016 1100 AM AST FRI JAN 15 2016 Surface observations, scatterometer, and geostationary satellite data indicate that Alex has weakened, and the current intensity estimate is 60 kt. Wind and pressure observations from Terceira along with the scatterometer data indicate that the center is tilted north-northeastward with height, indicative of some south-southwesterly vertical shear. The global models show significant thermal advection developing over the eastern portion of the circulation very soon, and observation from the western Azores show cold air advection. These factors indicate that Alex will likely become an extratropical cyclone later today. Some restrengthening due to baroclinic processes is possible in the short term, but the post-tropical cyclone is forecast to merge with or become absorbed by another extratropical low within 48 hours. Alex continues to accelerate and is now moving about 360/24. A gradual turn to the northwest is expected as the system rotates around a broader cyclonic gyre over the northern Atlantic. The official forecast track is roughly in the middle of the dynamical guidance. The forecast points and wind radii are based mostly on guidance from the NOAA Ocean Prediction Center.

Hurricane ALEX Forecast Discussion Number 7
2016-01-15 09:46:17| National Hurricane Center (Atlantic)
Issued at 500 AM AST FRI JAN 15 2016 000 WTNT41 KNHC 150846 TCDAT1 HURRICANE ALEX DISCUSSION NUMBER 7...CORRECTED NWS NATIONAL HURRICANE CENTER MIAMI FL AL012016 500 AM AST FRI JAN 15 2016 Corrected 48-hr forecast position The overall convective pattern of Alex has continued to erode since the previous advisory. However, conventional and microwave satellite imagery indicate that there is still enough inner-core convection and a small radius of maximum winds to warrant keeping Alex as a hurricane for this advisory. Satellite classifications continue to decrease, and the initial intensity has been lowered to 65 kt based on a blend of the TAFB current intensity estimate of T4.5/77 kt and a current T-number of T3.5/55 kt. Alex has yet to make the turn toward due north, and the initial motion estimate is 005/20 kt. Other than to nudge the forecast track slightly to the right based on the more eastward initial position, there are no significant changes to the previous forecast track or reasoning. Alex is expected to be steered northward and then northwestward over the next couple of days within deep cyclonic flow in the eastern periphery of a large extratropical low centered over the northwestern Atlantic near Newfoundland. On the forecast track, the center of Alex and the core of strongest winds should reach the central Azores by late morning or early afternoon. The global and regional model guidance remains in excellent agreement on this scenario, and the official forecast track is a blend of the consensus model TVCN and input from the Ocean Prediction Center. Most of the coldest cloud shield has now shifted into the western semicircle, a signal that extratropical transition is likely beginning. With Alex now moving over 16C sea-surface temperatures, and with colder water still ahead of the cyclone, transition to an extratropical cyclone should be complete within the next 12 hours. However, global models suggest that there will be enough baroclinic forcing to maintain hurricane-force winds after transition occurs despite the cold waters of the north Atlantic. The 34-kt wind radius was expanded in the northeastern quadrant based on quality wind reports from ship BATFR17. The wind field is expected to continue to expand as Alex undergoes extratropical transition at higher latitudes. The wind radii forecasts are based primarily on guidance from the NOAA Ocean Prediction Center.
