...Tropical Storm Ana to affect Hawai'i starting this weekend...

Note... The Central Pacific Hurricane Center is issuing advisories
on Tropical Storm Ana. Please consult their advisories for the
latest information.

Through the rest of this week, an upper low to the SE of the 50th
state will continue to move westward. To the north, a surface high
will weaken and slide eastward, allowing the trades to lessen for
the balance of the week. By Saturday evening, Ana will likely be
located about 100 miles to the SE of the Big Island and headed
northwestward. A surge in tropical moisture is likely over at
least the southeastern islands this weekend that will subside
slowly, depending on how quickly Ana exits the region (which may
not be too quickly). Several inches of rain appear likely near the
track of the system and on upslope regions with an increasingly
easterly flow. By next week, the ensembles indicate upper ridging
to creep closer to the NW islands from the west, which will
complicate the track of Ana by then.
