Dominica is especially vulnerable to hurricanes as the island is located in what is referred to as the hurricane region. In 1979, Hurricane David struck the island as a Category 4 hurricane, causing widespread and extreme damage. On 17 August 2007, Hurricane Dean, a Category 1 hurricane at the time, hit the island.  A mother and her seven-year-old son died when a landslide caused by the heavy rains crushed their house. In another incident two people were injured when a tree fell on their house. Prime Minister Roosevelt Skerrit estimated that 100 to 125 homes were damaged, and that the agricultural sector was extensively damaged, in particular the banana crop. In August 2015, Tropical Storm Erika caused extensive flooding and landslides across the island. Multiple communities were evacuated and upwards of 30 people were killed. According to a Rapid Damage and Impact Assessment prepared for Dominica by the World Bank, the total damage and losses from the storm were US$484.82 million or 90% of Dominica's yearly GDP. Category 5 Hurricane Maria struck the island in 2017 and caused losses of approximately US$930 million or 226% of GDP.
