A tropical storm is intensifying and is expected to reach typhoon strength before hitting southern China's coast on Sunday.

Florida could feel impacts from an area of tropical moisture that includes remnants of the same system that dumped rain over the state last weekend. Forecasters are also watching another developing tropical wave in the distant Atlantic Ocean.

The system, identified as Invest 93L, originally developed east of Florida before traversing the entire state and ending up over Louisiana and Mississippi.

The storm remains disorganized on Wednesday but still has time to strengthen over the Gulf before making landfall on Thursday.

The National Hurricane Center is tracking Invest 93L. Could tropical storm Dexter develop? What is the weather forecast for travel? What we know
