SAN JUAN, Puerto Rico (AP) — Hurricane Lee is whirling through open waters toward the northeast Caribbean becoming the first Category 5 storm of the Atlantic season. Lee was not expected to make landfall although forecasters said tropical storm conditions are possible on some islands. Meteorologists said it was too early to provide details on potential rainfall and wind gusts. The Category 5 hurricane was located about 705 miles (1,135 kilometers) east of the northern Leeward Islands. It had winds of up to 160 miles per hour (260 kilometers per hour) and was moving west-northwest at 14 mph (22 kph).
