However, it does appear that some dry air and a bit of mid-level shear are impacting the growth of Elida at this time. Regardless, based on the improvement on satellite imagery, the subjective Dvorak estimate remaining at T3.0/45 kt, and objective intensity estimates ranging widely from 38 to 57 kt, the current intensity has been slightly increased to 45 kt. Based on the satellite observations, Elida is moving slightly north of the previous forecast track at 280/12 kt. A prominent subtropical ridge north of Elida should maintain this general motion through the remainder of the day. Afterwards, this ridge is expected to shift eastward as a weakness develops ahead of Elida, associated with a mid-latitude trough located off the California coast. This synoptic weather pattern should allow Elida to begin gaining more latitude by the end of this week as it gradually turns northwestward. This track should continue through early next week. The track guidance is in fairly good agreement early on, but across-track spread increases notably by the end of the forecast period. The latest NHC track forecast was shifted a bit north and east based on a blend of the the GDMI, HCCA, and TVCN track guidance. The tropical storm remains over very warm waters with plenty of environmental moisture. However, mid-level shear appears to be undercutting the convective outflow, and this could be importing drier air from the north. Thus, short-term intensification is forecast to be slow. A faster rate of intensification could occur in 36-48 h if the storm develops a inner core. After 60 h, the tropical cyclone will cross the 26 C isotherm with weakening expected to begin by this weekend. The latest NHC intensity forecast maintains the same 80-kt peak as the prior cycle, and is close to the peak intensity of HCCA, but still higher than the HAFS-A/B guidance.
