Residents of Haiti were last night clearing up the devastation caused by Tropical Storm Hanna, as officials in the US prepared for the storm to hit. Hanna caused major flooding in Haiti this week, leaving at least 61 people dead and thousands more stranded on rooftops without food or clean water. The President, Rene Preval, has called the situation catastrophic and appealed for international help. A UN mission is assisting with relief efforts in the hard-hit northern city of Gonaives, where 200,000 people have been affected by floods and mudslides. Forecasters expect Hanna to regain hurricane strength today as it continues on a path toward the south-eastern US. The Governor of Virginia already has declared a state of emergency.
