Flooding was also reported in neighbouring Haiti which is still recovering from the devastating 7.2 M earthquake of 14 August in which 1,941 have now died and over 9,000 injured.

Reports via Social Media showed severe flash flooding occurred late on 16 August in areas of Sud-Est Department in Haiti, in particular Cayes-Jacmel and Marigot communes.

The timing couldn’t be worse for a population under huge strain. Hundreds of thousands have been left struggling for food, water or shelter after the earthquake. Rescue teams are still working through the earthquake debris in search for survivors.

United Nations Children’s Fund (UNICEF) said, “Tropical Depression Grace has compounded the situation, with heavy rains further disrupting access to water, shelter, and other basic services. Flooding and mudslides are likely to worsen the situation of vulnerable families and further complicate the humanitarian response.”


Tropical Storm Grace brought heavy rainfall to Jamaica on 17 August. The Office of Disaster Preparedness and Emergency Management (ODPEM) reported 13 incidents of flooding and 2 landslides as a result, mostly in eastern parts of the island and in particular in St Andrew’s Parish where ODPEM opened a refuge for anyone displaced by flooding

The storm has started moving away from Jamaica but more rain is forecast. According to the National Hurricane Center, Tropical Storm Grace could be near hurricane strength as it approaches Mexico’s Yucatan peninsula late Wednesday or early Thursday.
