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.

Dora advisory information was originally transmitted under the
incorrect headers this has been corrected.
