Dora remains a well-organized, compact and symmetric hurricane, 
moving west in the central Pacific. A blend of the subjective dvorak 
estimates from PHFO, SAB and JTWC combined with the objective 
estimates lends an initial intensity remaining at 120 kt. A partial 
SAR pass this morning showed winds on the northeast side near 90 kt, 
but may have missed some higher winds. 

Additional fluctuations in intensity are expected over the next 
several days as Dora continues a generally westward track along 
27/28 C water, in a negligible wind shear environment. Satellite 
shows significantly drier air several hundred miles north of Dora, 
which if it is ingested into Dora. A slightly more defined 
weakening trend is expected as some of that drier air is ingested 
into Dora in a couple days. The intensity forecast continues to 
follow the last few advisory packages for the first 36 hours, and 
remains a little higher than the model consensus. Starting with 48 
hours, the forecast intensity has been lowered a bit to keep it in 
line with the overall pattern of the intensity models. As the 
system moves into a more unfavorable shear environment beyond day 
4, additional weakening is likely. 

Very little change in the track forecast as models continue to be 
very tightly clustered through the week. Dora will move to the west 
along the southern edge of the ridge to the north, passing well 
south of Hawaii over the next several days.
