In its 11 a.m. advisory, the NHC said Tropical Storm Nigel strengthened again with maximum sustained winds of 60 mph, a jump from earlier in the morning.
The center of Tropical Storm Nigel was said to be about 990 miles northeast of the Lesser Antilles as it moved north-northwest at 13 mph.
“Nigel is expected to become a major hurricane by the middle of the week, but will move toward the north and be a fish storm,” Eric Stone, a meteorologist with Nexstar’s WFLA, said. A “fish storm” refers to a storm that doesn’t threaten land, but could cause problems for fishermen or along shipping routes.
Meanwhile, the NHC is tracking another area of interest off the west coast of Africa. A tropical wave there is expected to move off the coast Wednesday and could be a tropical depression later this week, according to forecasters.
The NHC said that system currently has a 40% chance of development over the next seven days.
