Tropical Storm Sara will cause 'potentially catastrophic' flash flooding in northern Honduras, according to the National Hurricane Center.

The National Hurricane Center is also asking residents of the eastern Gulf Coast, including Florida, to monitor the storm closely since it has the potential to reach the US.

Tropical Storm Sara made landfall in northern Honduras late Thursday and threatened to dump torrential rains across parts of Central America and southern Mexico. Sara hit land about 105 miles west-northwest of the Cabo Gracias a Dios on the Honduras-Nicaragua border,
