 Tropical Depression Lane Discussion Number  55
 NWS Central Pacific Hurricane Center Honolulu HI   EP142018
 500 PM HST Mon Aug 27 2018
  
 Visible imagery from Himawari continues to show an exposed low
 level circulation center. The closest cold, high clouds associated
 with Lane are over 90 nm northeast of the center. Subjective Dvorak
 intensity estimates from HFO, SAB and JTWC were all 2.0/30 kt. The
 initial intensity for this advisory has been lowered to 30 kt, and
 Lane has been downgraded to a depression.
  
 A strong east northeast to west southwest ridge north of Lane
 has continued to steer the storm toward the west. The initial motion
 for this advisory is 270/6 kt. Satellite water vapor loops show a
 deep low aloft near 23N 172W. Southwest flow associated with this
 low is producing strong southwest vertical wind shear over Lane. The
 UM-CIMSS shear estimate was 51.2 kt. The low aloft is forecast to
 induce a deepening north south surface trough along 170W. The
 weakening circulation of Lane will become part of this trough and
 turn toward the north northwest tonight.
  
 Lane is forecast to weaken to a post-tropical remnant low within 24
 hours. The remnant low will continue to weaken as a new
 extratropical low forms to the northwest. The remnants of Lane will
 become wrapped up into that low.
