Post-Tropical Cyclone Gil Discussion Number  14
NWS National Hurricane Center Miami FL       EP072025
500 AM HST Sun Aug 03 2025
 
Cool waters combined with a drier and more stable environment have 
taken their toll on Gil. The system has been devoid of deep 
convection overnight, with only an exposed swirl of low- to 
mid-level clouds remaining. The initial intensity is lowered to 45 
kt, based on a blend of the latest subjective Dvorak estimates from 
TAFB and SAB and objective estimates from UW-CIMSS. Given the cool 
waters, dry and stable air, and strengthening west-southwesterly 
shear, no new organized convection is expected. Therefore, this will 
be the final advisory on the system as it has become post-tropical. 
Gil is expected to dissipate around midweek as it opens into a 
trough northeast of the Hawaiian Islands.

The initial motion is estimated at 285/16 kt. The system is being 
steered by a low- to mid-level ridge to its north, and this general 
motion is expected to continue into tonight. A gradual decrease in 
forward speed is anticipated by Monday, followed by a turn toward 
the west as the shallow remnant low becomes steered by the low-level 
flow. The updated track forecast remains close to the previous 
advisory and continues to follow the tightly clustered guidance 
envelope.

Seas Forecasts issued by the National Weather Service, under AWIPS
header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at
