DISCUSSION
-----------------------------------------------
Earlier this morning, an eye began to appear in satellite imagery.
However, since that time the convection has eroded slightly over the
southwestern portion of the circulation, making that feature
somewhat obscured. This could be a sign that an eyewall replacement
cycle (ERC) is underway. Although the eye is not readily apparent
in satellite, Felicia has a well-defined inner core structure with
persistent and very cold cloud tops surrounding much of the center.
The Dvorak T-numbers continue to rise, and the latest blend of the
available values from TAFB, SAB, and the UW-CIMSS ADT support
increasing the initial intensity to 80 kt for this advisory.
Felicia continues to make a gradual turn to the left, and the
initial motion is now 270/10 kt. The ridge currently to the north of
the hurricane is foreast to shift to its northwest over the next day
or so, which will force the cyclone west-southwestward for a couple
of days. By early next week, Felicia should once again become
positioned to the south of the ridge, which would result in a
westward motion through the end of the forecast period. The latest
NHC track forecast is little changed from the previous one, and is
near the tightly clustered track guidance.
Rapid intensification (RI) has continued, and Felicia's winds have
increased by 50 kt since early yesterday morning. Aside from a
possible pause in the cyclone's intensification in the near-term
due to the ERC, the environment of low shear and warm sea surface
temperatures (SSTs) that have been supporting the strengthening
should continue around the cyclone over the next 24 h. By late
Friday, Felicia is forecast to move into a drier airmass which may
begin to disrupt the convection, while the cyclone also begins to
move over slowly decreasing SSTs. This should cause the system to
gradually weaken through the remainder of the forecast period. The
latest NHC intensity forecast is slightly above the bulk of the
guidance through 24 h due to the RI factors currently in place.
Thereafter, the forecast is close to the HFIP Corrected Consensus
Approach model HCCA.
