A huge new storm has formed in the Gulf of Mexico, the third to threaten the US in only six days.
Hurricane Katia has strengthened in the warm waters off the coast of Mexico, with winds of 75 miles per hour.
The US National Hurricane Center (NHC) has said the storm is predicted to grow stronger over the next two days, while models show it remaining in the Gulf for the time being.
The news comes as Hurricane Irma - a category five hurricane - barrels its way through the Caribbean towards Florida.
With sustained winds of 180 miles per hour, it has become the most powerful hurricane on record in the Atlantic Ocean.
On Irma's heels is tropical storm Jose, which is expected to become a hurricane as it moves towards the Caribbean.
At this point, Jose's path can't be accurately determined, so it remains unclear whether it will hit the mainland United States.
Meanwhile, Florida remains in a state of emergency as Irma moves towards it, with landfall expected at the weekend.
