Lala's deep convection has been decreasing in coverage, with 
continued evidence of dry air intrusion over the southern portion of 
the circulation.  Also, some southwesterly vertical wind shear 
appears to now be affecting the system.  Although Dvorak intensity 
estimates are slowly decreasing, a Metop-C scatterometer pass from a 
few hours ago suggests that the intensity is still near 40 kt.  The 
SHIPS guidance shows increasing shear over Lala with relatively dry 
air, and SSTs should remain near 23 deg C.  Therefore, additional 
slow weakening is likely and Lala is expected to degenerate into a 
post-tropical remnant low in 48 hours.  The system is forecast to 
cross the International Date line around that time as well.

Recent center fixes now show a slow north-northwestward motion 
around 330/4 kt.  A mid-level ridge to the northeast of Lala should 
result in a north-northwesterly to northwesterly track for the next 
few days.  The official track prediction is only a tad to the right 
and slightly slower than the previous NHC forecast.  This is in 
close agreement with the latest corrected consensus, HCCA, guidance. 
 Post-tropical Lala is forecast to accelerate deeper into the 
mid-latitudes over the weekend, and it should open up into a trough 
over the northern Pacific before reaching the western Aleutian 
Islands.
