Tropical Storm Barbara expected to become first hurricane of the season in Eastern Pacific
Tropical Storm Barbara formed off the southern coast of Mexico on Sunday morning, and forecasters say it's expected to become the first hurricane of the season in the Eastern Pacific. The National Hurricane Center (NHC) said Tropical Storm Barbara has maximum sustained winds of 45 mph and is moving off to the west-northwest at 12 mph. It's currently located about 180 miles south-southwest of Zihuatanejo, Mexico. How To Watch Fox Weather A tropical storm is a tropical cyclone that has maximum sustained winds between 39 and 73 mph – an upgrade from a tropical depression. The NHC said Barbara is expected to continue to move off to the west-northwest over the next few days before making a turn to the west at a slower speed on Tuesday. Tropical Storm Barbara is expected to strengthen over the next day or two, and it's expected to become a hurricane on Monday.

In addition, large waves at local beaches are expected to cause life-threatening rip currents. A few hundred miles to the west of Tropical Storm Barbara, showers and thunderstorms associated with a broad area of low pressure located about 600 miles off the southwestern coast of Mexico became better organized on Sunday morning. This disturbance has been dubbed Invest 91E by the NHC. What Is An Invest During Hurricane Season? Further development of Invest 91E is expected, and the NHC said a tropical depression or tropical storm is likely to form later Sunday or Sunday night as it moves northwestward at 5 to 10 mph. Once this system reaches tropical storm status with winds of at least 40 mph, it will receive the name Cosme. An area of low pressure is forecast to develop late this week south of southern Mexico. The NHC said environmental conditions appear conducive for some gradual development of this future low-pressure system, and a tropical depression could form late this week. According to the NHC, it has a medium chance of development over the next seven days. The Eastern Pacific hurricane season runs from May 15 to Nov. article source: Tropical Storm Barbara expected to become first hurricane of the season in Eastern Pacific

New area to watch joins Invests 91E, 92E in busy eastern Pacific tropics as Barbara looms this weekend
A busy start to the hurricane season in the eastern Pacific Ocean got even busier Saturday morning as the National Hurricane Center has now added a third area to watch for possible tropical development. 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.

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.
