Issued at 200 AM PDT Fri Aug 06 2021 000 WTPZ43 KNHC 060839 TCDEP3 Tropical Depression Hilda Discussion Number 27 NWS National Hurricane Center Miami FL EP082021 200 AM PDT Fri Aug 06 2021 Hilda has been reduced to a swirl of low- to mid-level clouds overnight with no organized deep convection. There has not been any recent scatterometer data to aid determining Hilda's intensity, but a blend of recent subjective and objective Dvorak intensity estimates support keeping the initial intensity at 30 kt. If Hilda fails to redevelop organized deep convection soon, an unlikely prospect since sea-surface temperatures under the depression are now around 22 C, the cyclone should soon become a remnant low, possibly as early as later this morning. Complete dissipation of the remnant low is expected by this weekend, well east of the Hawaiian Islands. The tropical depression is currently moving west-northwest at 300/10 kt. This heading is expected to continue until dissipation as the system moves along the southern periphery of a low-level ridge to its north. The latest NHC track forecast is largely an update from the previous one, though is a bit slower, following the tightly clustered track guidance.
