At 1200 PM CST (1800 UTC), the center of Tropical Storm Eta was
located near latitude 13.9 North, longitude 85.6 West. Eta is moving
toward the west near 7 mph (11 km/h). A west-northwestward motion
at a faster forward speed is expected this afternoon through

early this afternoon, and then move across Honduras later this
afternoon through Thursday morning. The system is forecast to emerge
over the Gulf of Honduras or the northwestern Caribbean Sea Thursday
night and Friday.
Maximum sustained winds are now near 45 mph (75 km/h) with higher

during the next day or two, and Eta should become a tropical
Tropical-storm-force winds extend outward up to 50 miles (80 km)
