Issued at 1100 PM HST Fri Sep 06 2019 000 WTPZ41 KNHC 070834 TCDEP1 Tropical Storm Juliette Discussion Number 25 NWS National Hurricane Center Miami FL EP112019 1100 PM HST Fri Sep 06 2019 Juliette is rapidly declining and is well on its way to becoming post-tropical. Cloud tops have warmed dramatically over the past few hours, and satellite intensity estimates have decreased sharply in turn. ASCAT data that arrived shortly before 06Z revealed that Juliette is not as strong as previously estimated, with max winds of only 35-40 kt. Based on that new info, the intensity has been adjusted down to 40 kt. The main change in the NHC forecast is that it now shows Juliette becoming post-tropical in 24 hours. Given current trends, it could certainly happen much sooner than that. Otherwise, the overall reasoning behind the forecast is the same. Juliette is located over quite cold waters and will steadily spin down over the next several days. The tropical storm has turned westward and should continue heading west through the middle of next week, steered by low-level easterly trade winds. This track will take the soon-to-be remnant low over warmer waters by day 5, and some of the dynamical guidance suggests that Juliette could try to make a comeback at that time. However, extremely high wind shear should prevent any convection that does develop from becoming organized and regeneration is not expected. The NHC track and intensity forecasts remain very close to the various consensus aids throughout the 5-day period.

Cloud tops have gradually warmed since the last advisory and several recent microwave overpasses show that convection is now limited to the eastern half of the cyclone. The intensity has been lowered to 55 kt based on the latest TAFB Dvorak fix. No substantial changes were made to the NHC track or intensity forecasts. Juliette is located over 23-24 deg C waters, and will remain over fairly cool waters for the next several days. Continued weakening appears inevitable and Juliette is forecast to become a remnant low within 48 h. Although the system will reach marginally warmer waters to the west by the end of the forecast period, it will have weakened enough that significant regeneration is unlikely at that time. The initial motion remains west-northwestward at 11 kt. Juliette should turn westward on Saturday as it weakens further and is steered entirely by low-level easterly flow. All of the models forecast that the tropical storm/remnant low will then continue westward for several days thereafter. The NHC forecast is very close to the East Pacific multi-model consensus TVCE.

The various satellite intensity estimates have continued to slowly decline, and now support an initial intensity of 60 kt. The tropical storm will be moving over cooler waters and into a more stable environment during the next 24 to 36 hours. This should result in steady weakening and Juliette is forecast to degenerate into a remnant low in 36 to 48 hours. The system will be moving back over slightly warmer waters later in the forecast period, but westerly shear should prevent any re-organization. Juliette is now moving west-northwestward or 295/11 kt. There has been no change to the track forecast reasoning. The cyclone should continue west-northwestward tonight, and then turn westward on Saturday as it weakens and is steered by the low-level easterly flow. The track guidance remains in good agreement but has trended slightly faster once again. The new official forecast was adjusted accordingly, and is once again near the TVCE multi-model consensus.
