Tropical Depression Hernan Discussion Number  11
NWS National Hurricane Center Miami FL       EP082026
500 AM HST Sat Aug 15 2026
 
Hernan continues to remain a swirl of low- to mid-level clouds with
no active deep convection. A recent OSCAT pass showed that the
winds are around 25 kts at most in the northern portions of the
cyclone. Considering a possibility of undersampling and that the
most recent TAFB Dvorak fix had a wind estimate of 30 kt, the
intensity has been held at 30 kt for this advisory.
 
Given that the cyclone is moving into an area of higher shear and 
drier air, Hernan is expected to continue to weaken and become a 
remnant low later today. The current forecast calls for a slow decay 
of Hernan to a trough in 60 to 72 h in agreement with the global 
models. 
 
The initial motion is 260/12 kt. A low- to mid-level ridge to the
north should steer Hernan and its remnants westward for the next
few days. The new forecast track is similar to, but a little faster
than, the previous track.
