A family in Panama Beach survived a nightmare
While the hurricane plundered a suburban neighborhood of Panama Beach called Cherokee Heights on Wednesday, Fatima Zogaj found herself trapped in a house that was falling around her and her his family.
Ms. Zogaj, 41, and her husband, Ahmed Alsaqqa, had not given much thought to squatting at home before the storm. They bought their brick house six blocks in brick, three years ago, far from the coast and in a neighborhood of recently constructed brick houses.
"We did not expect it to be that bad," Mrs. Zogaj said last night, staying out in a neighborhood of broken trees, flooded meadows and torn tiles.
The couple, Ms. Zogaj's mother and their four children encountered few problems during the first hour of the storm while the wind started whipping and howling. But soon the rain, blowing to the side, began to seep through the window of a guest room on the second floor. Their tiles began to take off.
