At first, Dayana Halawo’s children, 5 and 7 years old, thought Hurricane Harvey’s thunderclaps were a more familiar sound: bombs. Halawo, 28, and her family came to Houston from Syria as refugees last August, and until recently, she had planned to throw a party to celebrate their one-year anniversary in the country. But in the days leading up to the hurricane, she instead made five trips to the grocery store, returning each time she remembered another item she and her family might need to wait out the storm. She stopped by her neighbors’ homes to make sure they had enough food and water. By Sunday, the roads surrounding her home were flooded, forcing her to stay inside.
