 Tropical Storm Lane Discussion Number  54
 NWS Central Pacific Hurricane Center Honolulu HI   EP142018
 1100 AM HST Mon Aug 27 2018
 
 Visible imagery from Himawari continues to show an exposed low
 level circulation center with the cold, high clouds shearing off
 farther to the northest. Over the past several hours the amount of
 cold, high clouds has decreased in area and the tops have
 warmed.  Subjective Dvorak intensity estimates from HFO, SAB
 and JTWC were all 2.0/30 kt. The initial intensity for this
 advisory has been kept at 35 kt, but that may be generous.
  
 A strong east northeast to west southwest ridge north of Lane
 continues to steer the storm. The initial motion for this advisory
 is 260/6 kt. Satellite water vapor loops show a deep low aloft near
 24N 172W. Southwest flow associated with this low is producing the
 shear now impacting Lane. The low aloft is forecast to deepen a
 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.
