Tropical Depression Emilia Discussion Number 12
Wiki-Hurricanes Forecast Center
2:00 PM PDT Sat Jun 30 2018
Emilia continues to shed convection this afternoon as it enters an area of stable air characterized by a large swath of stratocumulus to the system's northwest. The small deep convective pocket that was present to the system's southwest this morning has lifted as a dense region of cirrus, so there are no active areas of deep convection currently present with Emilia. SAB and TAFB have given T1.5/25kt for their satellite intensity estimates. However, given the fairly large area of 30 kt winds sampled in this morning's ASCAT pass in a convectively free environment, the intensity this advisory is held at 30 kt, though this may be a bit aggressive.
No changes to the forecast philosophy this advisory, with westward motion being driven by the large Central Pacific subtropical ridge with some latitudinal ascent from some localized height anomalies north of the center. Sea surface temperatures have fallen beneath 25°C and should keep any new convection in check. Continued weakening is expected for the remanider of the forecast period, and shear increasing in 12-18 hours should be the final nail in the coffin for Emilia.
