Tropical Storm Sara formed this afternoon and threatens to bring "life-threatening and potentially catastrophic flash flooding and mudslides" to Honduras throughout the weekend, according to the latest update from the National Hurricane Center. A turn toward Florida is still possible, forecasters said.

Satellite imagery can help determine the strength, size and cohesion of a storm. The stronger a storm becomes, the more likely an eye will form in the center. When the eye looks symmetrical, that often means the storm is not encountering anything to weaken it. Sara is the 18th named storm to form in the Atlantic in 2024.

Tropical Storm Sara formed in the Caribbean and was expect to hit Central America and Mexico before emerging in the Gulf and moving toward Florida.
