Storm Nate has hit Costa Rica, Honduras and Nicaragua, killing at least 22 people.
More than 20 people are missing in the Central American nations and a state of emergency has now been declared.
The tropical storm is now heading north towards the US, according to the BBC.
So far the storm has caused heavy rain leading to flooding and landslides. This has damaged buildings and bridges as well as blocked roads.
The death toll in Costa Rica currently stands at eight. Thousands of people in the island country, which has a population of less than 5 million, are currently living in shelters and almost 400,000 have no running water.
When the storm then moved it Nicaragua it left a further 11 people dead. Three people in Honduras have died as a result of the storm, including two young people who drowned in a river.
In El Salvador emergency services have also reported the death of a man in a mudslide.
It is thought the storm is likely to grow stronger and by Sunday (October 8) could be categorised as a category one hurricane before making landfall on the south coast of the US.
If the storm does follow this prediction it could potentially be the third major storm to hit the area this year.
