Hurricane Irma grew to wind forces of 120 miles per hour by 8 a.m. on Monday with at least one model predicting that the storm will hit south Florida on Sept. 11.
Irma intensified to a Category 3 storm on Sunday and is expected to gain strength on Monday and Tuesday.
While there is no definitive prediction whether Irma will reach the U.S., a storm forecast model developed by the American National Oceanic and Atmospheric Administration and mapped by Ventusky.com shows the hurricane hitting south Florida on Sept. 11 with winds reaching 119 miles per hour. That prediction was based on weather data available at 11 a.m. Monday.
