currently drifting east-northeastward near 3 mph (5 km/h). Gamma is
forecast to gradually turn toward the southwest or west-southwest on
Monday and move slowly in that direction through mid-week. On the
forecast track, the center of Gamma will continue to meander
offshore of the northern Yucatan Peninsula tonight and pass near or

Tropical-storm-force winds extend outward up to 160 miles (260 km)
from the center.
