Tropical Storm Chantal showed signs Friday of gradual strengthening and a shift to the northwest, but the 40-mph storm remained far from land in the Atlantic.
By today “it should get interesting. It will have died away, or it will have strengthened significantly,” said National Hurricane Center forecaster Steve Lyons. “It could still go either way.”
At 11 a.m. EDT, the storm was about 200 miles northeast of San Juan, Puerto Rico, and about 1,100 miles southeast of Miami.
The distance made any predictions about landfall on the U.S. mainland very iffy.
