200 PM HST Tue Sep 17 2019

For the central North Pacific...between 140W and 180W:

1. Showers and thunderstorms are associated with an elongated area of
low pressure around 450 miles southwest of Honolulu. Environmental
conditions are expected to be marginally conducive for some
development over the next 24 hours as the system moves toward the
northwest. By late Wednesday or Thursday, chances for development
drop off significantly as the low interacts with another disturbance
approaching from the west. Regardless of development, this system is
expected to bring locally gusty winds and heavy rain to portions of
the Papahanaumokuakea Marine National Monument over the next several
days. 
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.

2. Showers and thunderstorms associated with a broad area of low
pressure, located about 950 miles west-southwest of Kauai, remain
disorganized. This system is expected to slowly move northeast into
unfavorable environmental conditions. Development, if any, will be
slow to occur. Regardless of development, this system is expected to
bring locally gusty winds and heavy rain to portions of the
Papahanaumokuakea Marine National Monument over the next several
days. 
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.

3. An elongated area of low pressure lies around 700 miles southeast of
the Big Island of Hawaii. Slow development is possible during the
next several days while the area slowly moves westward, though the
environmental conditions are only marginally favorable.
