The main area of concern is a broad area of low pressure located approximately 1,300 miles east-southeast of Hawaii. This area of low pressure will continue to move westward over the next few days and will move through an environment featuring warm ocean waters and relatively light wind shear. This should allow this feature to better organize over the next few days and will likely become a tropical depression or even a tropical storm. However, this feature should pose no direct threat to Hawaii during the upcoming week.
Elsewhere in the basin, a pair of tropical waves is found over the open waters. Neither of these waves are expected to develop.

000 ABPZ20 KNHC 160553 TWOEP Tropical Weather Outlook NWS National Hurricane Center Miami FL 1100 PM PDT Sun Jul 15 2018 For the eastern North Pacific...east of 140 degrees west longitude: Showers and thunderstorms in association with a low pressure system located about 1200 miles east-southeast of the Big Island of Hawaii are showing signs of organization. Environmental conditions are expected to be conducive for the development of a tropical depression during the next day or so before upper-level winds increase by mid-week. This system is moving westward and is expected to cross into the Central Pacific basin on Monday. * Formation chance through 48 hours...high...80 percent. * Formation chance through 5 days...high...80 percent. Shower and thunderstorm activity associated with a tropical wave located several hundred miles south-southwest of the southern tip of the Baja California Peninsula has changed little this evening. However, recent satellite-derived wind data indicate that this disturbance is producing gale-force wind gusts east of the wave axis in the strongest thunderstorms. Although the environment is expected to be only marginally conducive, some additional development is possible during the next day or so while the system moves westward to west-northwestward over the open East Pacific. By Wednesday, strong upper-level winds will likely prevent further development. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...low...30 percent. $$ Forecaster Stewart
