Tropical Depression Felicia Forecast Discussion Number 27

Issued at 1100 AM HST Tue Jul 20 2021 750 WTPZ41 KNHC 202047 TCDEP1 Tropical Depression Felicia Discussion Number 27 NWS National Hurricane Center Miami FL EP062021 1100 AM HST Tue Jul 20 2021 Convection once again has mostly dissipated near the low-level circulation of Felicia. Without any organized deep convection, the clock is now ticking on its remaining lifespan as a tropical cyclone. An ASCAT-A scatterometer pass that was recently received at 1709 UTC had a peak wind retrieval of 32-kt just north of the center. Given the lack of convection since that time, as well as the latest Dvorak estimates decreasing further, Felicia is being downgraded to a tropical depression at this time with maximum sustained winds of 30 kt. Further weakening is anticipated as Felicia remains in a very dry, stable environment. The depression is forecast to degenerate into a remnant low in the next 12 hours and open up into a trough by the end of the week, well south of Hawaii. The latest estimated motion is now to the west-southwest at 255/14 kt. The track philosophy has changed little this advisory as a large subtropical ridge will continue to steer Felicia to the west-southwest over the last few days of its life. The latest NHC track forecast is largely an update of the previous forecast track as the guidance remains tightly clustered along the forecast track. On this track, Felicia will be crossing into the central Pacific basin within the next few hours. This is the last advisory issued by the National Hurricane Center on Felicia.
