Tropical Storm Rafael churned in the central Atlantic early Monday as it approached hurricane strength, forecasters said.
Maximum sustained winds increased to 70 mph late Sunday, according to the National Hurricane Center in Miami. The storm was centered about 260 miles (420 km) north-northeast of San Juan, Puerto Rico, and was swirling north-northwest at 10 mph.
"Some additional strengthening is forecast ... and Rafael could become a hurricane on Monday," the hurricane center said.
