The number of deaths caused in Haiti by Tropical Storm Isaac has risen to 24, with three people still missing, according to the latest figures released Tuesday by the authorities.

Isaac, now headed toward the U.S. Gulf Coast, struck Haiti with heavy rains and gusting winds over the past weekend.

The provinces with the most fatalities were Ouest, which includes the capital Port-au-Prince, with 10 people killed, and Sud-Est with six.

As a consequence of the storm, which also left 42 people injured, according to the report, three people have gone missing.

There were also 8,189 families affected by the storm, with a total of 15,812 people forced to evacuate, of whom 7,753 remain in 62 provisional shelters, the government said.

Tropical Storm Isaac destroyed 1,005 houses, damaged 6,040 and flooded 1,144.

Isaac was approaching the north coast of the Gulf of Mexico on Tuesday and looked likely to strengthen to a Category 1 hurricane, putting the coastal areas of Louisiana, Mississippi and Alabama on maximum alert. EFE
