At least 10 people were reported dead in Haiti after Tropical Storm Isaac drenched the impoverished nation, the Associated Press reports.
A woman and a child died in the town of Souvenance, and a 10-year-old girl died in Thomazeau when a wall fell on top of him, according to the AP.
Isaac's greatest toll may be the results of its rainwater -- expected to amount to about eight to 12 inches on the island Hispaniola, shared by Haiti and the Dominican Republic, according to the Associated Press.
Floodwaters could bring mudslides and outbreaks of cholera.
Many living in tent cities were urged to go to shelters, but President Michel Martelly admitted to CNN that not everyone in camps would be able to get out.
"Those who are very vulnerable, they are moved out of these camps. And the ones who are remaining behind are those who are stronger to fight this situation," he said.
For those living in camps, shelter means tarps and shacks.
"We don't have houses that can bear a hurricane," Jeanette Lauredan, who lives in a tent camp in Port-au-Prince, told the Associated Press.
The Haitian government had about $50,000 in emergency funds and buses and 32 boats on standby for evacuations, the AP reports.
Isaac will hit Florida as a hurricane, according to the AP. Relief agencies are taking necessary precautions.
