Hurricane Luis, a 700-mile-wide tempest with winds as fast as 175 miles per hour, is expected to hit Puerto Rico late today or early Wednesday. For days, frightened residents and tourists have been crowding airports and air charter companies. "Everybody here is kind of frantic," reports TIME's Lorelei Albanese in San Juan. "Bottled water is almost completely sold out, and batteries and other supplies are being snapped up as soon as they are put on the shelves." Albanese says the ferocity of the storm has reminded many Puerto Ricans of Hurricane Hugo, which caused more than $1 billion in damage to the commonwealth in 1989. "People remember Hugo, and they're terrified it's going to be worse this time."
