Tropical Storm Sara stalled over Honduras on Saturday, drenching the northern coast of the Central American nation and swelling rivers.
The area could see life-threatening flash flooding and mudslides through the weekend, according to the Miami-based National Hurricane Centre.
Sustained rain fell overnight and continued into the morning in the city of San Pedro Sula, where there were no immediate signs of serious flooding.
People watched as the conditions brought back memories of the disastrous November 2020 hurricane season, when two powerful storms passed through the region, displacing hundreds of thousands of people and causing widespread damage.
The weather system made landfall late on Thursday about 105 miles (165 kilometres) west-northwest of Cabo Gracias a Dios, on the Honduras-Nicaragua border.
The Hurricane Centre expects the storm will move near the Bay Islands of Honduras on Saturday before approaching Belize.
Sara is then expected to turn northwesterly towards Mexico’s Yucatan Peninsula, though forecasters said it probably will not re-emerge into the Gulf after crossing the Yucatan.
The storm, however, did not stop a Concacaf Nations League match on Friday in San Pedro Sula. Under heavy rain, Mexico lost 2-0 at Honduras.
In November 2020, Eta and Iota passed through Honduras after initially making landfall in Nicaragua as powerful Category 4 hurricanes.
Northern Honduras caught the worst of the storms with torrential rains that set off flooding that displaced hundreds of thousands. Eta alone was responsible for as much as 30 inches of rain along the northern coast.
