Tropical Depression Orlene Discussion Number  21
NWS National Hurricane Center Miami FL       EP162022
400 PM CDT Mon Oct 03 2022
 
Strong west-southwesterly shear and the mountainous terrain of 
southwestern Mexico have taken a toll on Orlene.  The tropical 
cyclone has rapidly weakened, and is now estimated to be a 30-kt 
tropical depression.  A long-loop of one-minute GOES-17 visible 
satellite imagery suggests that the center likely came ashore 
slightly west of the earlier track, but close to the estimated time. 
Additional weakening is expected, and the low-level center is 
likely to dissipate this evening.  A 12-h point is provided for 
continuity but Orlene is not likely to exist as a cyclone by that 
time. 

Orlene is moving north-northeastward or 025/9 kt. The cyclone or 
its remnants should continue to move north-northeastward around the 
northwestern periphery of a mid-level ridge until dissipation 
occurs. 
 
Key Messages:

1. Heavy rainfall from Orlene is expected to lead to flash flooding, 
as well as possible landslides in areas of rugged terrain of 
Southwest Mexico through Tuesday.
