Tropical Storm Emily Discussion Number 2
NWS National Hurricane Center Miami FL AL072023
500 PM AST Sun Aug 20 2023
Emily is feeling the effects of southwesterly vertical wind shear
with the low-level center fully exposed to the southwest of the main
area of deep convection. The initial intensity is held at 45 kt
based on the earlier ASCAT data and the TAFB Dvorak satellite
estimate. The environment around Emily is expected to become
increasingly hostile the next couple of days with shear increasing
to near 40 kt while the system remains in relatively stable air.
These unfavorable atmospheric conditions should cause steady
weakening, and Emily could become a remnant low in a few of days.
The storm is moving to the northwest at 8 kt, and a general
west-northwest to northwest motion is expected during the next 2 to
3 days while the storm moves along the southwestern periphery of
the ridge. After that time, a turn to the north is forecast while
the storm moves around the west side of the ridge and toward a
weakness. The new track forecast is similar to the previous one and
near the middle of the guidance envelope.
