System loses its conviction to be Vince

MIAMI – A subtropical depression that formed in the open Atlantic was dissipating late Saturday, prompting forecasters to cancel a tropical storm watch issued for Bermuda.

The system was no longer a subtropical depression and had lost all of its convection, according to the National Hurricane Center in Miami.

At 11 p.m. EDT, the weakening depression’s center was about 250 miles southeast of Bermuda. It was moving toward the west near 14 mph, although the speed was expected to decrease during the coming days. It had top sustained winds of about 30 mph, but they were expected to weaken by today, forecasters said.

Long-term forecasts showed the system either reaching the United States mainland in about five days, or curving farther out to sea after passing Bermuda.

Had the system strengthened, it could have formed Tropical Storm Vince, the 20th named storm in one of the busiest hurricane seasons on record.
