The Pacific Ocean remains active even after Juliette dissipates, however, with hurricane center forecasters keeping an eye on three tropical waves with varying degrees of potential for development.
The system with the greatest chance of formation is currently a broad area of low pressure located several hundred miles south-southwest of the southern tip of the Baja California peninsula that is producing disorganized showers and thunderstorms, according to the NHC.
Environmental conditions appear conducive for the gradual development of this system, and a tropical depression is likely to form over the weekend as the system moves west-northwestward across the eastern Pacific basin. Forecasters give the system an 80% chance of formation through the next seven days.
An area of low pressure could also form this weekend or early next week off the southern coast of Mexico, the hurricane center said in an early morning advisory on Aug. 28. Environmental conditions appear conducive for some gradual development of this system thereafter, and a tropical depression could form by the middle of next week as it moves west-northwestward offshore of Mexico.
The hurricane center gives this system a 40% chance of formation through the next seven days.
Lastly, a trough of low pressure located several hundred miles south of the Hawaiian Islands is expected to move westward into unfavorable environmental conditions, and development is not expected, the NHC said.

NHC also tracking a tropical wave in the Atlantic
In the Atlantic, a tropical wave is forecast to emerge off the west coast of Africa on Sunday, Aug. 31, according to the hurricane center.
Forecasters said environmental conditions could support some slow development of this system as it moves westward to west-northwestward next week. The hurricane center gives the system a 20% chance of formation through the next seven days.
This forecast track shows the most likely path of the center of the storm. It does not illustrate the full width of the storm or its impacts, and the center of the storm is likely to travel outside the cone up to 33% of the time.
How do hurricanes form?
Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression.
A tropical depression becomes a named tropical storm once its sustained wind speeds reach 39 mph. When its winds reach 74 mph, the storm officially becomes a hurricane.
Develop an evacuation plan. If you are at risk from hurricanes, you need an evacuation plan. Now is the time to begin planning where you would go and how you would get there.
Assemble disaster supplies. Whether you’re evacuating or sheltering in place, you’re going to need supplies not just to get through the storm but for a possibly lengthy aftermath, NOAA said.
Get an insurance checkup and document your possessions. Contact your insurance company or agent now and ask for an insurance checkup to make sure you have enough insurance to repair or even replace your home and belongings. Remember, home and renters insurance don’t cover flooding, so you’ll need a separate policy for those. Flood insurance is available through your company, agent or the National Flood Insurance Program. Act now, because flood insurance requires a 30-day waiting period.
Create a family communication plan. NOAA says you should take the time now to write down a hurricane plan and share it with your family. Determine family meeting places and make sure to include an out-of-town location in case of evacuation.
Strengthen your home. Now is the time to improve your home’s ability to withstand hurricanes. Trim trees and install storm shutters, accordion shutters, and impact glass; seal outside wall openings.
