Hurricane Dora Discussion Number  26
NWS Central Pacific Hurricane Center Honolulu HI   EP052023
1100 AM HST Sun Aug 06 2023

Well-organized and compact Dora remains a very symmetric hurricane 
as it begins its journey into the central Pacific. A well defined 
clear eye with some marginal warming of cloud tops have been 
observed on satellite over the last couple of hours. Dvorak-based 
intensity estimates from PHFO, JTWC and SAB came in at 6.5, 
continuing to support an initial intensity around 120 kt. Recent 
cloud top warming could suggest a weakening trend, but given Dora's 
recent history of being stronger than the forecast, combined with no 
scatterometer or other observations to the contrary, will maintain 
the 120 kt intensity with this package. 

Some fluctuations in intensity are likely over the next several 
days as Dora moves over relatively warm water in a negligible wind 
shear environment. Drier air to the north of the system is expected 
to be ingested into the system within a few days and will help to 
weaken the storm midweek. The intensity models are in agreement with 
a weakening trend through the week, however they vary with regards 
to how much weakening occurs as the week progresses. The CPHC 
intensity forecast follows the NHC trend in the last few advisory 
packages of being a little above the model consensus.

Dora is expected to move to the west along the southern edge of the 
ridge to the north. On this track, Dora will pass well south of 
Hawaii over the next several days.  The model track guidance remains 
very tightly clustered through the week, thus the forecast track 
remains very close to the previous advisory.
