Tropical Storm Flossie, located off the southwest Mexican coast, is expected to strengthen into a hurricane early this week, according to forecasters at the National Hurricane Center (NHC).
Why It Matters
Flossie is the sixth named storm of the Eastern Pacific hurricane season.
The system arrives shortly after Tropical Storm Barry, which formed in the Gulf’s Bay of Campeche over the weekend.
What To Know
“Maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts,” the NHC said on Monday. “Steady-to-rapid strengthening is forecast during the next couple of days, and the system is expected to become a hurricane tonight or Tuesday.”

National Hurricane Center
The NHC said that tropical storm-force winds extended outwards up to 70 miles from the center of the system.
A tropical storm warning was issued for portions of southwest Mexico, and the NHC said tropical storm conditions were expected here late Monday through Tuesday.
At the time of writing, a tropical storm warning was in place from Punta San Telmo to Playa Perula.
Meanwhile, additional tropical storm watches were in effect for Zihuatanejo to east of Punta San Telmo, and for North of Playa Perula to Cabo Corrientes.
“Flossie may undergo rapid intensification in the next few days and has the potential to become a major hurricane,” AccuWeather lead hurricane expert Alex DaSilva told Newsweek.
“The storm is in a very favorable environment with plenty of warm water and low wind shear. While most of the strongest winds will remain well offshore, heavy rain and gusty winds are expected across southwestern Mexico this week, and in southern Baja California later in the week.”
The rainfall may trigger flash flooding and mudslides, particularly in elevated areas, DaSilva said.
The storm is also expected to produce hazardous waves, rip currents, and storm surge along the Mexican coast through Friday. Should Flossie move nearer to the coast, it could result in heavier rainfall and more extensive damaging winds, DaSilva added.
What People Are Saying
AccuWeather lead hurricane expert Alex DaSilva told Newsweek: “There can be some moisture that gets sucked up into the North American Monsoon and brought into Arizona, New Mexico and west Texas.
“Most of the moisture will be from the North American Monsoon itself, although some of the moisture will also be from what was Tropical Storm Barry on the Atlantic side.
“While there can be some localized flash flooding in the Southwest, most of the rain will be beneficial due to portions of Texas, Arizona and New Mexico being in extreme to exceptional drought.”
Meteorologist Jim Cantore said on X, Monday: “Meanwhile #flossie in the eastern Pacific is forecast to become a hurricane and likely enhance the monsoon in the southwest as deep moisture flows up into AZ, the Rockies and the High Plains into the weekend.”
What Happens Next
The Eastern Pacific Hurricane season began on May 15 and runs through November 30.
Meanwhile, the Atlantic hurricane season spans from June through November.
