An elongated low pressure "tropical wave" prompted several Central American countries to issue heavy rain warnings Tuesday, and called on their citizens to take protective measures.
In Honduras, authorities declared an alert in 14 of the country's 18 departments.
Costa Rica also declared an alert on its Pacific coast and central valley, which includes the capital, San Jose.
In El Salvador, the civil protection agency issued a warning about a tropical wave, which would bring "moderate risks of flooding and landslides due to persistent rains."
The Guatemala coordinator for disaster reduction warned of increasing rainfall due to the low pressure system over the Caribbean, while in Nicaragua rains have flooded dozens of homes in the capital Managua, and disrupted power supplies, according to the country's Civil Defense Agency.
The region has already seen a host of named storms and hurricanes in recent weeks, with the eastern Pacific season's first named storm, Arlene, leaving at least 16 people dead in Mexico earlier this month after it drenched much of the country with heavy rains and left hundreds of thousands homeless.
