Though slightly weaker and downgraded from tropical storm status, Hanna still could drench much of Honduras and northern Nicaragua with up to 38 centimetres of rain, according to the Miami-based National Hurricane Center.
"These rainfall amounts will produce life-threatening flash floods and mudslides," the NHC cautioned at 0001 GMT today.
Hanna, with top winds of 55 kilometres per hour, was forecast to move quickly inland and bring downpours to the region.
While heavy rains might sound like good news for parts of Honduras that have been experiencing drought, the dry conditions actually make the terrain in mountainous Central America more prone to mudslides.
