Tropical Storm Lala Discussion Number  53
NWS Central Pacific Hurricane Center Honolulu HI   CP012026
Issued by NWS National Hurricane Center Miami FL
500 AM HST Tue Aug 25 2026

The satellite presentation of Lala remains about the same as it has 
been for the last couple of days.  The cyclone continues to have 
well-defined curved bands of shallow-to-moderate convection with 
coldest cloud tops of -60 to -65 deg C.  Upper-level outflow is 
strongest over the northern semicircle of the circulation.  Based 
on an earlier scatterometer overpass with little change in 
structure since that pass, the advisory intensity remains at 45 kt.
 
Latest center fixes show that the storm is moving slowly 
west-northwestward with a motion estimate of around 300/5 kt.  The 
primary steering feature at this time is a weak mid-tropospheric 
ridge to the northeast of Lala.  The global models indicate that 
the stronger higher-latitude southwesterly flow will continue to be 
well-removed from the cyclone for the next few days.  Therefore the 
system is likely to continue a slow forward motion for the next 
72 hours or so.  The official track forecast is similar or very 
slightly to the west of the one from the previous advisory.  This 
is close to the latest corrected consensus, HCCA, solution.
 
Lala is forecast to traverse SSTs of about 23-24 deg C through 
Thursday and remain within a relatively dry low- to mid-level air 
mass.  These conditions should lead to slow weakening and gradually
diminishing deep convection.  It is likely that the system's deep 
convection will have decreased to the point that Lala will become a 
post-tropical cyclone by around 60 hours, and this is reflected in 
the latest NHC forecast.
