Post-Tropical Cyclone Lowell Discussion Number  21
NWS National Hurricane Center Miami FL       EP172020
1100 AM HST Fri Sep 25 2020

Lowell has been largely devoid of deep convection for more than 18 
hours, with only a small shrinking patch left more than 100 n mi 
northeast of the center.  Therefore, Lowell is now considered a a 
post-tropical remnant low, and this is the last advisory from NHC.  
The initial intensity is estimated to be 30 kt.

The remnant low is moving westward at about 11 kt.  A continued 
westward motion but at a slightly faster pace should occur during 
the next few days while the remnant low gradually weakens over cool 
waters and in an environment of stable air and increasing westerly 
shear.  The remnant low is forecast to dissipate a few hundred miles 
east-northeast of the Hawaiian Islands in 4 or 5 days.

For additional information on the remnant low please see High Seas
