New area to watch joins Invests 91E, 92E in busy eastern Pacific tropics as Barbara looms this weekend
But in the short term, two clusters of thunderstorms are on the cusp of becoming the basin's next named storms, but which area of disturbed weather will take the name Barbara remains somewhat of an open question.
Both thunderstorm clusters were designated as invests on Friday as they parallel or slowly drift away from the Mexican coastline.
The National Hurricane Center first designated the batch of developing thunderstorms farther away from the southwestern Mexican coast as Invest 91E on Friday. A few hours later, the cluster closer to the coast became Invest 92E.
An "invest" designation signals an area of heightened interest and allows the National Hurricane Center to run a collection of specialized datasets and computer forecast model guidance on that area of disturbed weather. These computer models simulate the system's projected track possibilities and predict its future intensity.

What Is An Invest During Hurricane Season?
Both 91E and 92E have a near-certain chance of developing into a tropical system over the weekend.
Invest 91E organized somewhat quickly and is expected to see continued gradual development. The NHC says a tropical depression is likely to form over the weekend or early next week while the system moves northwestward at about 10 mph.
It has a 70% chance of tropical development over the weekend.
What Is An Invest During Hurricane Season?
Invest 92E, located several hundred miles southwest of the Gulf of Tehuantepec, could potentially have impacts on Mexico's southwestern coast with rounds of heavy rains and high surf.
"Environmental conditions are conducive for further development, and a tropical depression or tropical storm is expected to form this weekend as the system moves west-northwestward at 10 to 15 mph," NHC forecasters said.
Invest 92E has an 80% chance of development over the weekend and thunderstorm activity has increased on the disturbance's eastern side, according to the Hurricane Center.
The next name on the list is Barbara. If both manage to form into a tropical storm, the latter one would be named Cosme.
Finishing out the trio, a new area to watch was tagged by the NHC on Saturday morning as an area of low pressure is forecast to develop late next week south of southern Mexico.
The NHC says conditions appear conducive for some gradual development of this system as it moves west-northwestward, but as of now just has a low chance of development over the nest week.
How To Watch Fox Weather
Tropical activity has been increasing in the basin since the start of the hurricane season on May 15.
Tropical Storm Alvin formed and quickly dissipated last week.

Hurricane Gil continues to churn far out in the eastern Pacific
MEXICO CITY (AP) — Hurricane Gil was continuing to churn in the eastern Pacific Ocean on Saturday but is not expected to threaten land and is likely to decrease in strength rapidly over the weekend, forecasters said. The Miami-based U.S. National Hurricane Center said the storm was about 1,160 miles (1,865 kilometers) west-southwest of the Baja California peninsula of Mexico. Gil had maximum sustained winds of 75 mph (120 kph) and was moving west-northwest at 20 mph (31 kph). No coastal watches or warnings were in effect. 'Weakening is forecast to begin Saturday, and Gil is likely to become post-tropical as early as Sunday,' the NHC said. It is a busy period for storms in the eastern Pacific. Another named storm, Iona, which also was once a hurricane, was downgraded from a tropical storm to a tropical depression as it moved far to the west of Hawaii. It, too, was not threatening land. Other storms could develop in the coming days in the eastern Pacific, forecasters said.

Tropical Storm Gil expected to become a hurricane Aug. 1: See tracker
Tropical Storm Gil continues to strengthen in the Pacific Ocean and is expected to reach hurricane status soon, while Iona is expected to remain in tropical storm status before gradually weakening. In an advisory issued at 5 a.m. Hawaiian Standard Time on Friday, Aug. 1, the National Hurricane Center said Gil is located about 920 miles southwest of the southern tip of the Baja California peninsula and moving toward the west-northwest. Gil has maximum sustained winds near 65 mph with higher gusts and further strengthening is forecast, with Gil expected to become a hurricane on Friday, Aug. 1, NHC forecasters said. Gradual weakening is expected over the weekend. Iona, meanwhile, is located about 1,295 miles west-southwest of Honolulu, Hawaii with maximum sustained winds near 40 mph with higher gusts. The storm is moving toward the west-northwest and this motion is expected to continue over the next couple of days with a gradual decrease in forward speed. "Little change in strength is forecast through Saturday," the hurricane center said of Iona, adding that "gradual weakening is forecast to begin on Sunday."

NHC tracking three other systems brewing in Pacific The hurricane center said in a July 31 advisory it is also keeping tabs on three other systems in the Pacific Ocean. The first system is currently a trough of low pressure located about 650 miles south-southest of Hilo, Hawaii, associated with disorganized showers and thunderstorms. "While the system currently lacks a well-defined low-level center, some development is possible during the next day or so," the NHC said, however environmental conditions are expected to become less conducive for further development by this weekend. The hurricane center gives the system a 10% chance of formation through the next seven days. Additionally, an area of low pressure is expected to form well southwest of southwestern Mexico within the next day or two, according to the hurricane center. Environmental conditions appear conducive for some gradual development of this system, and a tropical depression is likely to form late this weekend or early next week as the system moves west-northwestward. The NHC gives the system an 80% chance of formation through the next seven days. Lastly, an area of low pressure is forecast to form offshore of the coast of Central America and southern Mexico by the middle part of next week. Thereafter, environmental conditions appear conducive for some development as the system moves west-northwestward. The system has a 20% chance of formation through the next seven days, according to the NHC. 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 Fahrenheit. 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 miles per hour. When its winds reach 74 mph, the storm officially becomes a hurricane. Prepare now for hurricanes Delaying potentially life-saving preparations could mean waiting until it's too late. "Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," NOAA recommends.
