An earlier GMI microwave pass revealed that the eyewall has completed closed off, and this is also visible in the infrared images as a -70C black ring. A blend of the subjective and objective satellite intensity estimates yield 80 kt, but since that time, due to the much improved inner core now depicted in imagery, the initial intensity is raised to 100 kt. Rapid strengthening should continue during the next 12 hours or so. Beyond the short term intensification trend, Juliette is forecast to continue to move within a favorable atmosphere consisting of low deep-layer shear, a diffluent upper wind pattern, and warm oceanic temperatures which should allow Juliette to strengthen a bit further. Afterward, a steady weakening trend is forecast as Juliette traverses cooler water and moves into a more stable, drier marine layer air mass. Juliette's initial motion is estimated to be northwestward, or 310/9 kt. The cyclone should continue moving generally northwestward, or west-northwestward within the mid-tropospheric steering flow produced by a subtropical ridge to the north of Juliette, and an upper-level low just to the west-southwest. There's still quite a bit of across-track model spread beyond the 48 hour period in response to continued large-scale synoptic dissimilarities in the strength of the subtropical ridge. The NHC track forecast is similar to the previous one, and is close to the TVCE consensus model.

Issued at 300 PM MDT Mon Sep 02 2019 000 WTPZ41 KNHC 022036 TCDEP1 Hurricane Juliette Discussion Number 7 NWS National Hurricane Center Miami FL EP112019 300 PM MDT Mon Sep 02 2019 Juliette is clearly on the upswing. A banding eye is present in visible and IR imagery, and satellite intensity estimates around 1800 UTC were all near 65 kt. The IR presentation of the cyclone has continued to improve since then and the initial intensity has been raised to 70 kt, making making Juliette the 5th hurricane of the eastern North Pacific season, and the first hurricane in that basin since July 31. The hurricane has quickly strengthened today and I see no reason why this won't continue for the next 12 to 24 hours. Rapid intensification still seems like a distinct possibility, though the intensity guidance certainly suggests otherwise. It is surprising that none of the guidance shows Juliette strengthening very quickly during the next day or two despite the apparent favorable environment the hurricane is embedded within and the current intensification trend. The NHC forecast remains above all of the intensity models for the first 48 hours, given the impressive structure of the hurricane. Beyond that time, the forecast is again close to the multi-model consensus and shows Juliette weakening quickly as it moves over cooler SSTs and into a dry environment. Juliette has slowed down and the initial motion is now 305/10 kt. There is no change in the forecast reasoning, and Juliette is still generally expected to be steered west-northwestward by an extensive deep-layer ridge located to the north and northeast of the cyclone. The models remain in very good agreement on the forecast of Juliette for the first 3 or 4 days of the forecast, and confidence remains high through that period. The global models then vary on the strength of the ridge and the model spread is notably higher by the end of the forecast. For now, the NHC forecast continues to split the various models and closely follows the multi-model consensus at all times.

Issued at 900 AM MDT Mon Sep 02 2019 000 WTPZ41 KNHC 021441 TCDEP1 Tropical Storm Juliette Discussion Number 6 NWS National Hurricane Center Miami FL EP112019 900 AM MDT Mon Sep 02 2019 Juliette is nearing hurricane strength. An increase in deep convection that was noted with the previous advisory has persisted, and recent microwave data shows that the cyclone has developed a well-defined inner-core. Given the observed increase in Juliette's organization, the initial intensity has been increased to 60 kt, which is supported by the latest UW-CIMSS ADT and SATCON fixes. Juliette is forecast to quickly strengthen today, and rapid intensification is a real possibility during the next 24 hours or so given the seemingly favorable environment and the presence of an low- to mid-level eye in recent microwave data. Beyond 48 h, the cyclone should begin to weaken as it moves over cooler SSTs and encounters a drier surrounding environment. The NHC intensity forecast is near the multi-model consensus from 72 h through the end of the period, but there is a fair amount of uncertainty as to how quickly Juliette will weaken since it will be moving along a sharp SST gradient. A track farther north than the NHC forecast would likely cause Juliette to weaken faster than anticipated, while a farther south track could allow it to maintain its strength for longer. Very little change was made to the track forecast. A deep-layer ridge to the northeast of Juliette should keep it on a generally west-northwestward to northwestward heading for the next 3 or 4 days days. The track guidance is particularly tightly clustered through that period and confidence in the forecast is high. The ridge could amplify by day 5 and cause Juliette to turn westward, as shown most notably by the ECMWF, though confidence is a little lower at that time. The NHC forecast is very near TVCE and HCCA at all times and lies near the middle of the guidance envelope.
