Issued at 500 PM AST Fri Sep 18 2020 000 WTNT43 KNHC 182045 TCDAT3 Tropical Storm Wilfred Discussion Number 2 NWS National Hurricane Center Miami FL AL232020 500 PM AST Fri Sep 18 2020 There haven't been a lot of changes with Wilfred today, with the northern side of the circulation looking rather dry while the center remains close to a burst of convection. The initial wind speed is kept 35 kt, closest to the TAFB classification. Wilfred could strengthen some during the next day or so before increasing upper-level westerlies winds likely begin by Sunday. A gradual weakening is expected into early next week, though the model guidance is in worse agreement than the last advisory due to the positioning of an upper-level low. The forecast continues to show the storm ending up on the convergent side of the low and dissipating, close to the previous one. Wilfred is moving west-northwestward at about 16 kt, after accounting for a re-positioning westward. Most of the guidance agrees on a scenario that maintains this track for the next few days, with a turn toward the west as the cyclones dissipates. The new forecast is closest to the GFS-based guidance. Similar to the intensity forecast, however, there are some models that suggest Wilfred could slow down and turn to the right in a couple of days if it is stronger than anticipated.
