11pm Sunday: Irma shifts a bit east

The center of Hurricane Irma was located by NOAA Doppler radar near latitude 27.5 North, longitude 81.9 West. Irma is moving toward the north near 14 mph (22 km/h).  A turn
toward the north-northwest and then northwest at a faster forward speed is expected during the next day or so.  On the forecast track, the center of Irma will continue to move over the western Florida peninsula through Monday morning and then into the southeastern United States late Monday and Tuesday.

Doppler radar data indicate that maximum sustained winds have decreased to near 100 mph (155 km/h) with higher gusts.  Additional weakening is forecast, and Irma is expected to become a tropical storm over far northern Florida or southern Georgia on Monday.

Irma has a very large wind field. Hurricane-force winds extend outward up to 80 miles (130 km) from the center, and tropical-storm-force winds extend outward up to 415 miles (665 km).
