MIAMI - Tropical Storm Lisa slowed on Thursday after making landfall in Belize, causing flooding and plunging parts of the country into darkness as it churned westwards toward Mexico.
Both Mexico and Belize dropped their coastal tropical storm warnings as the former hurricane weakened and headed west at 16km/h, according to the US National Hurricane Center (NHC) in Miami.
Forecasters warned that the tourist-popular coast of Central America and the Yucatan Peninsula should continue monitoring the situation as the maximum sustained winds decreased to around 75km/h.
For the next day or so, the storm system is expected to pack a gusty punch and deliver heavy rain, swells and flash flooding to northern Guatemala and southeastern Mexico, further weakening as it moves inland.
Lisa slammed into the Sibun River just southwest of economic hub and former capital Belize City around 2120 GMT on Wednesday, uprooting trees, downing power lines and inundating streets.
"It's very dangerous for us" because in Belize "it floods quickly, even with moderate rain," Jasmin Ayuso, a 21-year-old secretary, told AFP.
A state of emergency was declared in two areas, while a curfew was in effect until dawn on Thursday.
Some parts of Belize were left without power as the storm lashed the country of about 405,000 people.
"BEL is aware of power outages affecting several areas of the country," the utility wrote on Facebook. "We assure the public that our teams are taking note of the reports of damages to the power system, including fallen power lines and poles."
Schools and most businesses were closed in anticipation of the storm and the government set up several shelters.
The NHC said Lisa could drop up to 250 millimetres of rain in some areas of Belize, northern Guatemala and several states in southern Mexico.
The Yucatan Peninsula, Honduras' Bay Islands and other areas of Central America were forecast to receive up to six inches of rain.
In Guatemala, heavy rain caused flooding and landslides in the northernmost department Peten on the border with Belize.
About 143 people were evacuated and 48 remain in a shelter, Oscar Cossio, secretary of the National Coordination for Disaster Reduction (CONRED), told a press conference.
