Tropical Storm Sara, a disorganized mass of rain and thunderstorms, was slowly meandering along the northern coast of Honduras on Friday morning, after making landfall near the Honduras-Nicaragua border late Thursday.

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

Tropical Storm Sara formed Thursday in the Caribbean, and is poised to deliver "potentially catastrophic" rainfall in Honduras in particular. It's not yet clear if it will threaten the Gulf Coast, though it's possible.
