The satellite presentation of Lala has slowly deteriorated tonight. 
Water vapor imagery shows some drier air has worked its way into the 
circulation, which has led to diminished convection and warming 
infrared cloud tops near and around the center. The Dvorak current 
intensity estimates from JTWC and HFO have decreased to T2.5/35 kt, 
and so the initial intensity is lowered to 40 kt.

Fixes from recent AMSR3 and GMI passive microwave images suggest 
Lala has resumed a slow northwestward motion (310/4 kt), steered by 
a mid-level ridge just to the northeast of the storm. This ridge 
should keep Lala on a slow northwestward heading while the storm 
approaches the International Date Line (IDL). The updated NHC track 
forecast has been nudged to the right of the previous one, in 
response to an eastward shift in the latest track guidance envelope. 
Lala will remain in a fairly dry mid-level environment while 
encountering increasing shear over cool waters during the next 
couple of days. Thus, continued weakening is forecast, and Lala is 
predicted to lose organized convection and become a post-tropical 
low by 48 h as it reaches the IDL. 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 by 120 h.
