Hurricane Max has formed off the coast of Mexico's southern Pacific coast and is forecast to hit land later today.
Initially a tropical storm, Max has strengthened into a Category 1 hurricane.
The US National Hurricane Centre issued a hurricane warning for the coastline between Zihuatanejo and Punta Maldonado.
It warned that Max could still strengthen a bit before reaching land and threatened to bring "life-threatening flooding [and] rainfall" to Guerrero and Oaxaca states.
Hurricane Max has maximum sustained winds of 75mph (120 kph).
The storm was located about 55 miles (85 kilometres) southwest of Acapulco and is heading toward the east at 6mph (9kph).
Earlier this week, Hurricane Irma wreaked havoc across the Caribbean before causing historic destruction in Florida.
Around 61 people were killed by Irma.
At least 38 were killed across the Caribbean and 23 deaths were reported in Florida, Georgia and South Carolina.
