Tropical Depression Hernan Discussion Number  10
NWS National Hurricane Center Miami FL       EP132020
900 AM MDT Fri Aug 28 2020

Satellite imagery shows that Hernan has become less organized since 
the last advisory with most of the associated convection 
dissipating.  In addition, surface observations in the coastal 
areas near the cyclone suggest the possibility that it no longer 
has a closed circulation, although there are no observations over 
water to confirm this.  Based on decreasing satellite intensity 
estimates, Hernan is downgraded to a tropical depression.  
Additional weakening is forecast, and Hernan is expected to 
degenerate to a remnant low pressure area as it moves over the Baja 
California peninsula later today and tonight.  The system is then
expected to weaken to a trough on Saturday.

The initial motion is a somewhat uncertain 295/18.  Hernan is 
moving around the northeastern side of the monsoon gyre that 
contains Tropical Storm Iselle, and a general west-northwestward 
motion is expected until the system dissipates on Saturday.
