Through Friday expect moderate to brisk trades as supported by
strong eastern Pacific high pressure.  Guidance continues to
suggest that a pocket of enhanced moisture, originally from
tropical cyclone Frank, should cross the islands late
Wednesday-Thursday.  Thus generally windward focused rainfall may
be locally heavier in this time frame.  T.S. Howard is forecast to
weaken to post-tropical/remnant low status as it tracks toward the
state during the next few days.  Reflecting a gradual southward
trend in the guidance over the past 24 hours, the 0900 UTC
National Hurricane Center advisory now indicates a track into the
northwestern islands by 0600 UTC Monday.  This track increases the
potential for significant rainfall over the central/northwestern
islands from the weekend into the beginning of next week.  Any
drier trend after the departure of Howard may be brief as T.S.
Ivette should come into the picture by around next
Wednesday-Thursday.  Based on the current range of guidance for
Ivette's track toward the end of the period there will be the
threat for another episode of heavy rainfall and possibly enhanced
winds.
