By DÁNICA COTO, The Associated Press SAN JUAN, Puerto Rico (AP) — Ernesto strengthened into a hurricane on Wednesday as it dropped torrential rain on Puerto Rico and left nearly half of all clients in the U.S. territory without power as it threatened to become a major storm en route to Bermuda.

The storm was located about 175 miles northwest of San Juan, Puerto Rico and was moving over open waters. It had maximum sustained winds of 75 mph and was moving northwest at 16 mph (26 kph). “The official forecast still reflects the possibility of Ernesto becoming a major hurricane in about 48 hours,” the National Hurricane Center said late Wednesday morning.
