Mexico City — A hurricane warning has been issued for part of Mexico's Pacific coast as Tropical Storm Erick intensified.

Erick was a tropical storm in the North Pacific Ocean Tuesday morning Mexico Central Time, the National Hurricane Center said in its latest advisory. The tropical storm had sustained wind speeds of 45 miles per hour.

Tropical Storm Erick is expected to rapidly intensify into a hurricane this week, with some meteorologists anticipating it will reach major hurricane status before making landfall in Mexico on Thursday morning.
